The use of fossil fuels continues in the face of rising global energy demand, continued consumption and investment in new fossil fuel plants, and energy use, the report said. lower biomass such as using wood or agricultural waste in heating and cooking. Burning fossil fuels such as coal, gas and oil produces carbon dioxide, the main greenhouse gas that contributes to global warming. As concentrations of CO2 in the atmosphere rise to record levels, governments have called for stronger emissions cuts and curbs on fossil fuel use to meet global climate goals.

The share of fossil fuels in the global energy mix was 80.2% in 2019, compared with 80.3% in 2009, while renewables such as wind and solar accounted for 11, REN21 said. 2% in the energy structure in 2019 and 8.7% in 2009. The remainder of the energy mix consists of traditional biomass, which is used largely for cooking or heating in homes in the developing world. However, in many regions, including parts of China, the European Union, India, and the United States, it is now cheaper to build new wind or solar photovoltaic plants than to operate new ones. existing coal plant. Renewable energy is also competing with new natural gas-fired power plants in terms of cost in many locations and is the cheapest source of new electricity generation in countries on all continents, the report said. big land. “We are waking up to the bitter reality that the climate policy promises of the past ten years have been almost empty words,” said Rana Adib, CEO of REN21. “The share of fossil fuels in final energy consumption has not shifted an inch,” she added. In many countries, the Covid-19 economic recovery packages aim to stimulate further investment in renewable energy. But renewable investments only account for about one-sixth of investment in fossil fuels, the report added.

On June 13, Tesla CEO tweeted that he will accept Bitcoin electric vehicle payments again. However, this only happens when Bitcoin miners can prove that about 50% of the energy they use is clean energy. According to Reuters, Bitcoin price increased 5% to 37,360.63 USD at 1:10 am on June 14 (Vietnam time) after Mr. Musk’s tweet. Musk also said that Tesla will sell about 10% of its Bitcoin holdings to show that Bitcoin can be easily liquidated. During the first quarter of the year, Tesla sold about $272 million in “virtual assets,” which reduced its operating loss by $101 million. Tesla CEO comments about cryptocurrencies often cause price fluctuations. As a result, he was criticized by CEO Magda Wierzycka of asset management company Sygnia as a “market manipulator” and that the US Securities and Exchange Commission (SEC) should investigate. In February, Tesla revealed in an SEC filing that it had purchased $1.5 billion in Bitcoin and would accept Bitcoin as payment for its products. However, then the electric car company paused due to concerns about the method of mining virtual currency, which requires huge electricity consumption, affecting climate change. “We are concerned about the rapidly increasing use of fossil fuels to mine and trade Bitcoin, especially coal, which is the worst emitter,” Musk tweeted in May.

VinFast electric bus during test run Not only buses, coaches should also be encouraged to use trams Air pollution and fine dust threaten people’s quality of life. Every year, Vietnam has to pay a large amount of money, about 8-10 billion USD to import gasoline. Part of this is spent on operating traditional fossil fuel-powered vehicles. In addition to the proposed inner-city electric buses for application in Hanoi and Ho Chi Minh City. In Ho Chi Minh City, it is thought that the government should consider the early policy of putting electric-powered intercity passenger cars into operation in order to both exploit the superiority of electric vehicle technology, while protecting the environment and bringing a a new look for public passenger transport in the new era. The world’s two major problems, which are environmental pollution due to emissions and energy security due to the finiteness of fossil energy sources (coal, oil, gas) have gradually become urgent. Air pollution, fine dust in Vietnam has become serious with big cities like Hanoi, Ho Chi Minh City, etc. Ho Chi Minh. Here, it is recorded that there are maximum number of days in a year with the most dramatic air quality index – the most polluted air in the world. In the past two years, authorities at all levels have met to discuss and direct long-term radical solutions to further strengthen the control of air pollution, including the control of carbon emissions and fine dust from the air. means of transport. And fossil energy sources are not available in all countries. Vietnam is one of the importing countries, still heavily dependent on the world’s oil (although it is also partly domestic), it is estimated that it still has to import about 8-10 billion USD per year. With zero emissions and using electricity instead of petrol, electric vehicles are said to be a breakthrough solution for Vietnam in the context of the need to strengthen air pollution control, ensure energy security and suitability. with the development trend of the world’s means of transport. Simple structure of electric vehicles compared to vehicles using internal combustion engines “Electric vehicle” (EV) is often understood as a vehicle with an electric motor drive system. From the outside, an electric car looks like a car with an internal combustion engine (petroleum car). However, except for some parts and components for sharing, about 70% of the components of the two vehicles are different. The significant difference between electric vehicles and vehicles using internal combustion engines is the number of moving parts. Electric vehicles have only one moving part, which is the electric motor (motor), while cars using internal combustion engines have tens of thousands of different parts. Important components of electric vehicles include: battery, electric motor control system, regenerative braking system and powertrain. The number of spare parts for moving parts is less than in electric cars, which leads to another important difference, which is that electric cars require less maintenance (more economical to operate) and safer. safer, in addition to the advantages of environmental protection, civilized and modern technology. Why electric cars are becoming more and more popular At the United Nations Climate Change Conference 2015 (COP 21) held in Paris (France), the participants reaffirmed their efforts to strengthen the response to climate change. The Paris Agreement announced in December 2015 has set a target to limit global temperature rise to below 2 degrees Celsius. This goal can only be achieved when the energy and other sectors significantly reduce emissions. greenhouse gas emissions. The transport sector accounts for about a quarter of emissions from energy-related industries. The goal of reducing greenhouse gas emissions to contribute to achieving the goal of reducing global warming below 02 degrees Celsius can only be achieved with a strong commitment of the transport sector. The Sustainable Development Report of the International Energy Agency (IEA) has shown that, to achieve this goal, by 2050, the world’s transport sector must contribute at least one-fifth of total greenhouse gas emissions. cuts from energy use activities. Electric cars are identified as a key factor contributing to reducing greenhouse gas emissions in the transport sector, increasing energy efficiency, reducing greenhouse gas emissions in general, encouraging the development of new energy sources and recycled energy. In the context of rapid urbanization, the development of electric cars also contributes to reducing air pollution and noise pollution in big cities. The main obstacles to the development of electric cars are the initial cost of the car and the time available between two charges of the battery. However, the recent rapid development of science and technology has shown positive signs. According to a recent report by the US electric car company Proterra, a single charge for the bus can be up and running for 650 km and the price is becoming more and more relevant to the market to ensure more competitive exploitation than traditional gasoline-powered vehicles. Level of use of electric vehicles in countries around the world To date, China is the leading country in production, domestic consumption and export, with the famous electric car manufacturer BYD. In China, according to the data at the end of 2018, the total number of electric buses put into operation is over 421,000 units, Shenzhen city uses 100% of electric vehicles in public passenger transport, while Beijing and Shanghai , the utilization rate of electric buses has reached over 80%. Electric buses are increasingly popular in provinces and cities in China. Europe ranks 2nd among countries using electric vehicles with 2,250 units, the number of electric vehicles used will increase as some European countries such as the Netherlands set a target to convert and use 100% electric vehicles. (including buses, coaches plus and private cars) by 2024. The United States is also the country that is starting to shift towards using more electric vehicles. Although there are only over 300 electric buses in the United States, the number of electric buses is increasing in the near future, with the city of Los Ageles having just decided to buy 155 electric buses to serve all passenger transport activities. in this city. With the new energy policy (Green New Deal), led by many famous electric vehicle manufacturers such as Telsla, Proterra and even Apple recently announced the new Apple car electric car model, there is sure to be a boom in usage. electric vehicles in the United States under the new administration are clearly visible. For electric vehicles, environmental protection is always a top priority Why use an electric car? As mentioned above, electric vehicles are vehicles without chimneys, do not emit CO2, greenhouse gases into the environment. Therefore, the exploitation of electric vehicles in passenger transport is completely environmentally friendly, which is not controversial. Many researchers, policy makers still argue. The first is the traceable environmental issue of electric vehicles, that is, the source of electricity that electric vehicles use is clean electricity, that is, electricity using renewable energy such as solar power, wind power … or electricity from heat. Obviously, over the past time, the Government has called on businesses to invest in the production of solar power, rooftop voltage and wind power…, this electricity has been purchased by the state and connected to the national grid. Only the current supply has not met the demand and more clean electricity is needed to connect to the network. The second is the problem that the production of batteries for electric vehicles is still energy-intensive and emits a significant amount of CO2. As stated, today’s technology is evolving like crazy. As the demand for electric vehicles and batteries increases, mass production of large capacity batteries will result in better environmental control and lower loss and emissions. Here, it is a matter of deciding for the electric vehicle industry to have a direction in which to invest, cooperate and develop. When domestic manufacturers have been proactive in technology, it is possible to produce and recycle used batteries, thereby closing the production and exploitation process effectively and ensuring the problem. environment. What are the implications for passenger transport in Vietnam in the new period? Facing the environmental context, the challenge of air pollution as well as ensuring national energy security, Vietnam should consider the development of electric cars as a breakthrough policy for technology development, domestic auto industry. The introduction of electric vehicles into transport operation has really been a push to change for the progress to serve the travel needs of people and socio-economic development in the new period. The use of electric vehicles for public passenger transport is not only in the inner city as the project of electric buses in Hanoi and Ho Chi Minh City. Ho Chi Minh City as the media recently mentioned, but also hereby recommended that the State should have a policy to encourage the development of electric vehicles for inter-provincial passenger transport (both for fixed and non-fixed routes). To do this, the state has policies to socialize and encourage transport business owners to use electric vehicles in transport business activities; encourage businesses to invest in charging station infrastructure at rest stops, bus stations and other concentrated stops for re-energized vehicles to serve well for transport activities. In short, the policy to encourage the use of electric vehicles is a right one, in terms of both environmental protection as well as energy security. In addition to electric buses as currently proposed to be applied in the inner city of Hanoi, Ho Chi Minh City. Ho Chi Minh City is also considering the application of intercity buses running on electricity. With a national electric passenger transport network being formed, improving user experience, increasing the quality of transport services, electric cars will have a good future in Vietnam, gradually replacing the traditional means of transport. fossil fuel-powered transportation.

Accordingly, the image shared by Elon Musk shows a couple having problems in love. (Photo: Reuters) The girl said that the love affair between the two would end if the boy continued to post the lyrics of the group Linkin Park. And the guy replied, “So in the end it didn’t even matter?” – are the lyrics to the band’s famous “In The End”. With the hashtag #Bitcoin and a broken heart, along with a photo of an angry couple and the song “In the End,” it seems like Elon Musk is hinting that his love of Bitcoin is over. (Screenshots) Bitcoin immediately dropped 2.8%, to $37,800. Prior to that, Bitcoin was on a rebound from multi-month lows, to climb to nearly $40,000. The cryptocurrency market was also affected and dropped heavily after Bitcoin unexpectedly plunged. Before that, Elon Musk has repeatedly made Bitcoin and other digital currencies go up and down like a “roller coaster” with his tweets. (Image: POOL/AFP via Getty Images) Most notably, last month, he took a 180-degree turn when he decided to stop allowing customers to buy Tesla cars with Bitcoin, citing concerns that Bitcoin mining would harm the environment. “Tesla has stopped accepting car purchases with Bitcoin. We are concerned about the rapidly increasing use of fossil fuels for Bitcoin mining and trading, especially coal. Cryptocurrency is a good idea on many levels and we believe it has a promising future, but that cannot come at a cost to the environment. (Photo: AFP) Tesla will not sell any Bitcoin and we plan to use it for transactions as soon as we transition mining to more sustainable energy,” Elon Musk said in an announcement posted on Twitter on the 13th. /5. Even so, Bitcoin supporters still argue that this drop will be a stepping stone for the currency to continue setting new records in the near future.

Specifically, Germany will provide $9.72 billion (€8 billion) for 62 projects it has selected to reduce emissions in the transportation, steel and chemical sectors. According to Economy Minister Peter Altmaier, Germany wants to be a global leader in hydrogen technology, noting that the just announced investment is a step towards making the German economy neutral. with carbon. Mr. Altmaier said that, through the use of hydrogen, Germany could annually cut several million tons of carbon dioxide (CO2) emissions from the steel and chemical industries. Germany has ambitions to lead the world in green hydrogen production. Photo: DW. Transport Minister Andreas Scheuer added: “We are making Germany a hydrogen country. A total of 95% of road traffic still depends on fossil fuels, so Germany needs transport based on renewable energy… We have to push and want to accelerate the transition to mobility. climate-friendly transition”. The German Energy Ministry will oversee 50 of these 62 projects, including plans for more than 2 gigawatts (GW) of electrolytic capacity to produce green hydrogen. This is 40% of the 5 GW target in Germany’s national hydrogen strategy by 2030. The Ministry of Transport will finance the remaining 12 projects in the transport sector. These activities will include the development and production of fuel cell systems and vehicles, including cars, trucks and buses… Hydrogen has gained a lot of momentum in recent years. It is appearing in almost every major oil company strategy and can be seen in many government plans for industrial decarbonisation. Governments, international organizations and oil and gas companies say that blue hydrogen (hydrogen plus carbon is collected and stored) and blue hydrogen (hydrogen produced by electrolysis of water using electricity from energy) solar or wind) could be the key to helping industries decarbonize waste in the energy transition.

But recently, paleontologists have had to change this view and push the herbivorous history of dinosaurs to the early Cretaceous period, 125 million years ago, grasses began to appear. This was discovered during the study of fossils of the dinosaur Equijubus found in China. Mount Mazong is located at the northern end of the Hexi Corridor, in present-day Gansu Province, China. The mountain is named because it looks like a horse’s mane blowing in the wind. Mazong Mountain is a desolate place, but beneath that gravel are the remains of creatures that died hundreds of millions of years ago. In 2000, paleontologists from China and the United States formed a joint expedition to unearth paleontological fossils in the Mazong mountain area. During this excavation, paleontologists discovered a large number of fossils. Chinese paleontologist You – Hailu studied the fossils of a new dinosaur species and he named this dinosaur Equijubus. The genus name is derived from the Latin words “equus” meaning “horse” and “juba” meaning “mane”, the genus name meaning “horse mane” because the fossil was found in Mount Mazong. The new species was given the full name Equijubus normani, with “Normani” being named in honor of the famous British paleontologist David B. Norman. Illustration. Equijubus can be considered an intermediate dinosaur between Iguanodon and Hasrosauridae. Equijubus has a fairly large body when compared to a “basic” Hasrosauridae, but they can still run on two legs after being chased by predators. Fossil specimens of this dinosaur include skulls, lower jaw bones, cervical vertebrae, dorsal vertebrae and other parts. Through fossil analysis, it can be seen that Equijubus belongs to the primitive Hadrosauridae, it already possesses some features of Hadrosauridae, but its skull also has obvious features of Iguanodon. Paleontologists surmise that the dinosaur Equijubus could be up to 7 m long, 2 m high and weigh 2.5 tons, almost the size of a small truck. Equijubus would have had a long head, a horn beak on the front of its mouth and flat teeth on the inside of its cheeks, allowing it to chew on hard plants. Equijubus also have a robust body, they often walk on all fours and run on two legs when fleeing predators. Although there are not many fossils of this species, the discovery of Equijubus has great significance for paleontology. As a very primitive Hadrosauridae, Equijubus has shown that the Hasrosauridae may have originated in Asia and that they evolved directly from Iguanodon. 14 years after the Equijubus species was named, paleontologists are once again studying their fossils using the latest technology. They found evidence of herbivorous dinosaurs actually eating grass in fossils! On December 21, 2017, You Hailu and other paleontologists published a research paper titled “Dinosaur-related cuticles and crystals from the Chinese Gramineae family of the Cretaceous Period” on National Science Journal of China. The paper mentioned that the microstructure of primitive herbaceous plants (herbs, rice) was silicified between the teeth of the dinosaur Equijubus. This suggests that herbaceous plants were originally the food of this dinosaur. In fact, to answer the question of whether or not herbivorous dinosaurs ate grass, we need to know that the grass family is a large family of plants with more than 650 genera. Rice, wheat, corn, millet, sorghum, etc… the plants that we cannot live without are all grasses, and many other plants that we can eat are also grasses. People have always doubted the existence of the grass family, and the time period of its appearance is also quite unclear. And in the past, scientists always thought that they appeared after dinosaurs. But through the discovery of secrets from the fossils of the dinosaur Equijubus, we have learned that grass appeared on Earth 125 million years ago. This means that on Earth, dinosaurs of that time also had herbivorous habits (literally eating grass). The earliest known seed-bearing plants can be traced back to the Middle Jurassic or earlier, 164 million years ago. It was discovered during the Boda Jurassic period in Inner Mongolia. Although this plant is only a few centimeters tall, it already has roots, stems, leaves, and fruits.

Mentioning Van Kieu mountain is probably not strange to many people, this place is a famous mountain of Taoism located in Xiangning district, Linfen city, Shanxi province, China. Van Kieu Mountain is currently a national grade 5A tourist destination, compared to other places, although its popularity is not high, it is well worth a visit. This mountain scenic area mainly includes Zushiding, Yuhuangding, Taerpo ancient village, Wulong palace and other scenic spots. In particular, the ancient village of Taerpo is a place few people know about. Taerpo ancient village (Thap Ba) not only has magnificent and beautiful natural scenery but also has a deep cultural heritage. The historical record of the origin of this place goes back 1500 years. According to legend, Lao Tzu came here while traveling around the world, later many Taoist alchemists came here, the most famous being Qiu Xu Co. Thap Erba ancient village is located on the mountainside, beautiful natural scenery, giving people the feeling of paradise. Stroll along the cobblestone street in the village, flanked by many old houses, most of which are very well preserved. Many architects have come here to survey and identify them as “living fossils of residential buildings”. As the village was expected to become a tourist attraction, the original inhabitants who lived here were moved to new homes under the mountain. The traffic here is very inconvenient, going down to the foot of the mountain will have a much better living environment, which is also a good thing for the locals. Through the houses built in the style of a cave, although there are some places that are dilapidated, it also partly shows the past years of history. As an important part of the national 5A tourist attraction, in Thap Ba ancient village, you can experience rich features such as waist dancing, shadow puppetry and local wedding customs. Talking about the most unique feature of Son Tay, many people will immediately think of a folk art form of flower molding. The flowers are molded in many different shapes and colors, just like a work of art.

Illustration. https://tinhtexaydung.petrotimes.vn In a statement released alongside a major new report, the Paris-based organization said achieving the net zero emissions target “Net Zero” would require an “unprecedented transformation”. about how energy is produced, transported and used globally”. In a clear indication of the amount of work that needs to be done, the IEA report said existing commitments fell “far below what is needed to achieve net-zero global emissions by”. year 2050″. According to the IEA’s roadmap to achieve Net Zero by 2050, more than 400 “milestones” will need to be crossed. These include phasing out new fossil fuel sales by 2025 and ending sales of internal combustion engine cars by 2035. In addition, there should be no “investment in new fossil fuel supply projects, and no further final investment decisions for new coal plants”. Preliminary figures from the US Energy Information Administration show that: The share of natural gas and coal in utility-scale power generation in 2020 is 40.3% and 19.3%, respectively. . According to the IEA scenario, solar and wind photovoltaic will become the leading source of electricity for the planet before the end of the decade, accounting for nearly 70% of electricity production by 2050. According to the IEA’s roadmap, solar energy will become “the largest source of total energy on the planet” by the middle of this century. In contrast, fossil fuels will see their market share “fall from almost four-fifths of total energy supply today to more than one-fifth.” Employment in the clean energy sector will increase by 14 million people in the period to 2030, while the role in the oil and gas and coal sectors will decrease by about 5 million people. “Our roadmap shows the priority actions needed today to ensure that the opportunity for net zero emissions by 2050 is narrow but still attainable,” said Fatih Birol, CEO. of the IEA, said in a statement. “The scale and speed of the efforts required by this important and formidable goal, our best chance of tackling climate change and limiting global warming to 1.5 °C makes this perhaps the biggest challenge humanity has ever faced,” added Birol. Cutting anthropogenic carbon dioxide emissions to Net zero by 2050 is considered critical once the 1.5°C target is reached. Later this year, the COP26 summit will take place in the Scottish city of Glasgow. This is seen as a hugely important event, with many hoping it will act as a catalyst for governments to step up their climate ambitions to achieve the goals set out in the Paris Agreement. . The reality shows how challenging the IEA’s roadmap is. As energy companies are still discovering new oil fields, while in countries like the United States fossil fuels continue to play an important role in electricity generation. https://tinhtexaydung.petrotimes.vn

On May 21, G7 pledged to completely stop funding coal-fired power plants. On May 21, environment ministers from the Group of Top Industrialized Countries (G7) agreed to take concrete steps by the end of the year to stop government funding for coal-fired power plants as part of efforts to curb global warming. In a statement after the two-day video conference, the G7 environment ministers said: “(We) are committed to taking concrete steps towards an absolute end to the new direct government assistance. for international coal-fired power generation by the end of 2021, including through Official Development Assistance (ODA), export finance, investment, financial support and trade promotion” . However, the statement did not mention the possibility of phasing out coal-fired power generation, leading analysts to believe that the G7’s call would have little impact on global efforts to tackle the problem. climate change issue. The removal of government support for fossil fuel financing, which emits large amounts of greenhouse gases that warm the Earth, is seen as essential to limiting the growth of fossil fuels. global temperature increase at 1.5 degrees Celsius, above pre-industrial levels. (according to Kyodo)

The star-nosed mole is a species of small mole found in the humid lowlands of eastern Canada and the northeastern United States, with records along the Atlantic coast as far as extreme southeastern Georgia. It is the only member of the tribe Condylurini and the genus Condylura. Blobfish (also known as teardrop fish) – a fish voted by the Ugly Animal Preservation Society as the standard of evil. This fish was first found in the waters of New Zealand and Australia, at depths between 600 and 1,200 meters. These are also places where the pressure is about 118 times higher than sea level. If you’ve ever seen a cephalopod recently discovered by scientists, perhaps all the strange things in this world will become completely normal, and also not surprising. , because this creature is considered the strangest species. Essentially it looks like an oversized paper clip or a long “beard” on the head, they have a curved body with twists. This animal is called Diplomoceras maximum. It’s a pity that no matter in any zoo on the planet or on a deep-sea diving boat, you won’t be able to see this animal, because it is just like Tyrannosaurus. This animal lived in Antarctica during the Cretaceous period 68 million years ago and what we can see today are only their fossils. The age of the fossils is about 68 million years, the end of the Cretaceous period, the same time as the tyrannosaurs. This strange squid mainly inhabits the waters around present-day Antarctica. It is possible that they became extinct at the same time as the dinosaurs because of the catastrophic impact of the asteroid Chicxulub. The fossil of this strange squid was discovered by the Antarctic Expedition at the UK’s University of Leeds. Scientists conducted a scientific investigation on Seymour Island in the Antarctic peninsula for six years and discovered more than 6,000 fossils of marine life. The most special of these is the squid Diplomoceras maximum (Paperclip squid). Fossils of paperclip squid are now on public display at the Earth Museum in Ithaca, New York, if you’re lucky enough to see it, you won’t be able to imagine why this animal grew up like that. – it is about 1.5 meters long and can be up to 2 meters long, equivalent to the height of a human; if it stretched out its paperclip-shaped body in a straight line, its body length would exceed 4 meters. Their assumption is consistent because shells are known to grow by accretion, creating new growth each year. After shrinking the giant shells of these 1.5-meter-long animals, the researchers concluded that the only plausible explanation is that these animals have a lifespan of about 200 years. In addition, the most surprising thing to scientists is that this paperclip squid has a lifespan of up to 200 years, speculated now from the ridges on their shells, this calculation is similar to the way Calculate the age from the ridges of the tree trunk. Their shells were developed through accretion, based on repeated patterns of carbon and oxygen isotopes, which scientists believe reflects annual methane production on the seafloor. This means that the paperclip’s shell will grow one more groove each year, and it will grow longer and longer. And the question is why this squid was able to live so long, while modern cephalopods, such as cuttlefish and squid, have a lifespan of less than 5 years even when they are the largest species of this family or the cephalopods are also shellfish, they can only live up to 20 years. So paperclip ink can live to be 200 years old is completely strange and mysterious. New research published at an online meeting of the American Geological Society claims to have discovered new evidence for a previously unknown creature with a very long lifespan. To answer this question, paleontologists have put forward a threefold hypothesis – they suggest that their habitat at that time was similar to that of the Greenland shark, which lived in cold waters. The price of Antarctica, have long and dark winters, lack of food sources, so they have to slow down their metabolism to increase their chances of successful reproduction, so their lifespan is also increased.

Van Xuong fish. You probably never thought that an animal could live without a head, heart and bones. In fact, this species existed 500 million years ago and exists until today, in addition, they are also considered “cousins” of the ancestors of many vertebrates today. The family of vertebrates is extremely prosperous today, with more than 60,000 members, all of whom have different looks, habits and temperaments, but this “cousin” only has one child left. the only living species, they are named Amphioxus – Van Xuong fish, this species is also considered a living fossil. Although Van Xuong fish is called a fish and at first glance, it is very similar to a fish, but it is not actually a fish. On our planet today, most of the animals that exist are vertebrates, such as horses, cattle, sheep, chickens, ducks, dogs, cats, tigers, turtles.. Of course, there are us humans as well. What makes this particular “fish” so strange and unlike any other is that they are cephalopods, without a backbone, but still grouped with vertebrates, Chordates live and form the phylum Chordate. Biologists think that Van Xuong fish are animals in the transitional evolutionary stage from invertebrates to vertebrates, today they are considered to be ancestors of fish, but they are completely different. not fish. The skin of Van Xuong fish consists of two main layers: the epidermis (epidermis) on the outside and the dermis (dermis) on the inside. Unlike most vertebrates, their epidermis has only one layer of cells, while the dermis is underdeveloped, mainly composed of glue or elastic connective tissue. There are more than 66,000 animals in the order Phylum Chordata. The most special thing is that vertebrates account for the largest proportion, with more than 66,000 species, the main subphylum is the sea squid, and there are currently about 3,000 known species; and cephalopods, there are only two families of Van Xuong and Asymmetron fish – there are 30 species. In fact, the skeleton of this fish is the rope that runs along the body and back from the tail to the head. In the gill slit region, the skeleton is a network of many horizontal and vertical connecting rods. The fins and tentacles are also supported by the connecting rod. Their central nervous system is a neural tube running along the body, located above the spinal cord but not reaching the end of the spinal cord, wrapped in a protective glue membrane. Although Van Xuong fish looks like a fish, the biggest difference between it and vertebrates is that it does not have a real head, sense organs such as smell, sight and hearing, even a skull or a skull. teeth are also something too fictitious for them. This animal only has a tuft of elastic “legs” on the head that acts as support for the body. The most amazing thing is that it doesn’t even have a heart, instead it relies on the beating of a portion of blood vessels to transport blood. Their musculature is less differentiated and typically segmented. Therefore, the muscles can only guarantee simple bending movements, suitable for the lifestyle buried in the sand. The muscular system consists of many muscle segments (myomera), arranged from the anterior end to the posterior end of the body. The muscle segments are separated by septa of connective tissue (myosepta). The muscle segments on both sides of the body are arranged alternately with comb teeth. As a result, when swimming, the body bends in the horizontal plane. Amphioxus is widely distributed in the shallow waters of the ocean, Qingdao and Xiamen in China are their main habitats. In addition, there are the coasts of Southeast Asia and the coasts of California and Florida, Norway, the Mediterranean and Africa. Due to its rich nutrition and delicious taste, Van Xuong fish is considered a traditional delicacy in Southeast Asia. Van Xuong fish is 3 to 5cm long, very strange shape. The long, flattened body looks almost like a pole. The whole body is pinkish-pink, semi-transparent, the muscle fibers are clearly visible. They have no scales, no fins, no spine, their internal organs are just a rhythmically pulsating complex tube. There are no senses like eyes, nose, ears. There is no decomposition for the gastrointestinal tract. Apart from the mouth and pharynx, the only remaining part of the intestine is the intestine leading to the anus. Van Xuong fish often follow the tide to swim into the estuary where the seabed is shallow, almost defenseless but capable of penetrating the ground. Their lifespan is about 3-4 years, they often bury half of themselves in the sand, while the other half is exposed to receive plankton from the river. Their musculature is less differentiated, so they can only move in the water by simple bending movements. When not moving, they often bury themselves in the sand. The respiration of Van Xuong fish is also similar to other fishes. They vibrate the cilia (the tentacles in the mouth) to bring water from them to the gill slit. The wall of the gill slit has many blood vessels, where gas exchange occurs.

Billionaire Elon Musk. (Photo: Bloomberg) “We are concerned about the increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, the largest emitter of all fuels,” Musk wrote on Twitter. 12/5. As the world’s largest digital currency by market capitalization, Bitcoin lost nearly 8% in value after Musk posted the above tweet, according to data from digital currency exchange Coinbase. “Digital currency is a good idea from many perspectives and we believe it has a promising future, but this should not come at a great cost to the environment,” Musk wrote. Tesla and SpaceX boss and ardent supporter of digital currencies and has created great excitement for this market this year, especially with Bitcoin and Dogecoin. Back in January, the price of Bitcoin skyrocketed when Musk named the coin in his tweet. The price continued to rise sharply after Tesla revealed that it bought $1.5 billion in Bitcoin and that people can use the coin to buy Tesla cars. As the price of Bitcoin continues to rise to new levels, environmental activists warn about the significant amount of fuel used to mine Bitcoin. The reason is that this operation requires the use of very powerful computers to verify Bitcoin transactions. Every year, Bitcoin mining uses as much electricity as the whole country of Argentina, according to estimates by Cambridge University. China accounts for 65% of global Bitcoin mining. That carbon footprint goes against Musk’s advocacy of clean energy. But he did not give up Bitcoin. In a tweet posted on May 12, he said that Tesla will not sell any Bitcoin and that Tesla intends to keep this currency to use for transactions “when Bitcoin mining becomes more environmentally friendly”. Musk also said that Tesla is looking for low-energy digital currencies.

Tesla stops trading in bitcoin. (Source: Forbes) On May 12, the world’s largest electric vehicle maker Tesla (USA) announced that it would stop using bitcoin in its car sales due to concerns about environmental issues. On his personal Twitter page, Tesla’s CEO, US billionaire Elon Musk wrote: “Tesla stopped using bitcoin to buy and sell cars. We are concerned about the use of bitcoins. fossil fuel for bitcoin mining and trading is increasing, especially coal – the worst emission fuel.” Tesla suggested that cryptocurrencies are a “good idea” with a “promising future” but “that cannot be achieved at a huge cost to the environment. Tesla emphasized that it will not sell “any bitcoin” but intends to use it for trading as soon as “bitcoin mining” transitions to more sustainable energies. This can be considered as a move to reverse the view of Elon Musk and Tesla, after facing criticism from environmentalists and investors. In the first quarter of this year, Tesla spent $1.5 billion buying bitcoin, then selling about 10% to bring in more than $100 million in profit. Immediately after the above announcement, the world’s largest digital currency lost more than 7% of its value and is trading at $52,669. In the Asian market, at one point bitcoin fell 17% to $45,700, its lowest level since March 1. Currently, this virtual currency has partially recovered to over $50,000. Bitcoin has a high level of security, appears and is distributed completely automatically based on algorithms and anyone can own it through deciphering mathematical equations and giving answers. dig.” To be able to earn bitcoins, “miners” will have to solve complex computational problems through a “miner” that consumes a lot of electricity. Researchers from the University of Cambridge (UK) believe that the total energy consumption of bitcoin mining in 2021 could reach 128 billion kWhm, accounting for 0.6% of the world’s total electricity production and high than electricity usage in Norway.

Explaining his decision, Elon Musk expressed concern that “the use of fossil fuels for Bitcoin mining is rapidly increasing.” Elon Musk has just announced, Tesla will “pause buying cars with Bitcoin”, because of concerns that the use of fossil fuels to mine Bitcoin is increasing rapidly.

Cryptocurrency is a good idea on many levels and we believe it has a promising future, but that cannot come at a cost to the environment. Tesla will not sell any Bitcoin and we plan to use it for transactions as soon as we transition mining to more sustainable energy,” Elon Musk wrote on Twitter. The recent announcement of billionaire Elon Musk on Twitter. (Screenshots) After Elon Musk’s announcement, the cryptocurrency market quickly “red” when the price of Bitcoin plunged below the $50,000 mark, losing more than 12% in the last 24 hours. Bitcoin price this morning, this coin previously dropped below $47,000 after Elon Musk’s announcement.

In early February, Tesla announced that it had spent $1.5 billion to buy Bitcoin, as well as saying that it could invest in a number of other digital currencies in the future.

By the end of March, Elon Musk announced that users in the US could buy Tesla cars with Bitcoin.

The star-nosed mole is a species of small mole found in the humid regions of eastern Canada and the northeastern United States, with records along the Atlantic coast as far south-east as Georgia. It is the only member of the genus Condylurini and genus Condylura. Blobfish (also known as water drop fish) – a fish voted by the Ugly Animal Preservation Society … the standard of evil. This fish was first found in the waters of New Zealand and Australia, at depths from 600 to 1,200 meters. These are also locations where the pressure is about 118 times higher than sea level. If you ever saw a new species of cephalopods discovered by scientists recently, perhaps all the strange things in this world would be very normal, and not surprising. , because this creature is considered the most exotic. Essentially it looks like an oversized paperclip or a bunch of long “antennae” on the head, they have curved bodies with twisted lines. This animal is called Diplomoceras maximum. It’s a pity that no matter where you live in any zoo on the planet or ride a diving boat to explore the deep sea, you will not be able to see this animal, as it is just like Tyrannosaurus. This animal lived in Antarctica during the Cretaceous period 68 million years ago and what we can see today is only their fossil. The date of the fossils is about 68 million years, the late Cretaceous period, the same time the dinosaurs. This strange squid mainly inhabits the waters around present-day Antarctica. They may have gone extinct at the same time as the dinosaurs because of the catastrophic impact of the asteroid Chicxulub. This bizarre squid fossil was discovered by the Antarctic Expedition at the University of Leeds, UK. Scientists conducted a scientific investigation on the island of Seymour in the Antarctic peninsula for 6 years and discovered more than 6,000 fossils of marine life. The most special of these is Diplomoceras maximum squid. The fossils of paperclip are currently on display to the public at the Earth Museum in Ithaca, New York, if you were lucky enough to be seen, you wouldn’t be able to imagine why this creature grew like that. – it is about 1.5 meters long and can be up to 2 meters long, which is equivalent to human height; if its paperclip-shaped body was stretched out in a straight line, their body length would exceed 4 meters. Their assumption is consistent because the shell is known to grow by accretion, creating new growth each year. After shrinking the giant crust of these 1.5-meter-long animals, the researchers concluded that the only plausible explanation was that these animals had a lifespan of about 200 years. In addition, what surprised scientists the most was that the paperclip squids had a lifespan of up to 200 years, speculation now calculated from the edges on their shell, which is similar to the method. Calculate the age from the trunk lines. Their shells are developed through accretion, and based on the repetitive characteristics of carbon and oxygen isotopes, scientists believe this reflects the annual production of methane on the seabed. This means that the paperclip ink’s cover will grow one more groove each year, and it will grow longer and longer. And the question is why this squid is able to live so long, while modern cephalopods, such as cuttlefish and squid, live less than 5 years even if they are the largest of this family or the cobra is also a shellfish, which can only live up to 20 years. So paperclip ink can live to 200 years old is completely strange and mysterious. New research published at an online meeting of the American Geological Association claims the discovery of new evidence suggesting a very long lifespan has never been known before. To answer this question, paleontologists have come up with a temporary hypothesis – they suggest that their habitat at that time was similar to that of the Greenland sharks, which lived in cold seas. Antarctica’s prices, which have long and dark winters, lack food sources, so they have to slow down their metabolism to increase their chances of reproducing successfully, so their lifespans are also increased.

You probably never thought that an animal could live without a head, heart, or bones. In fact, this species existed 500 million years ago and exists to this day, in addition they are considered “cousins” of the ancestors of many species of vertebrates today. The vertebrate family of today is extremely prosperous, with more than 60,000 members, all of them with different looks, habits and temperament, but this “cousin” has only one child. Only alive, they are called Amphioxus – Van Xuong fish, this species is also considered living fossils. Although Van Xuong fish is called fish and at first glance it is very similar to fish, it is not actually fish. On our planet today, most animals that exist are vertebrates, such as horses, cattle, sheep, chickens, dogs, cats, tigers, ba … Of course, there are us as well. What makes this particular “fish” so exotic and unlike any fish is that they are vertebrates, have no vertebrates but are still grouped with vertebrates, cord animals and form the Chordate branch. Biologists believe that Van Xuong fish are animals during the transition from invertebrates to vertebrates, today they are considered to be the ancestors of fish, but they are completely not fish. The skin layer of Van Xuong fish has 2 main layers, the outer epidermis and the dermis on the inside. Unlike most vertebrates, their epidermis has only 1 cell layer, while the epidermis is underdeveloped, mainly composed of colloid or elastic connective tissue. There are more than 66,000 species of animals in the order Phylum Chordata. The most remarkable thing is that vertebrates make up the largest proportion, with more than 66,000 species, the main caudal subsector is the sea level, and there are currently about 3,000 known species; and head vertebrates, only two families of fish Van Xuong and fish Asymmetron – there are 30 species. In fact, the skeleton of this fish is the wire that runs along the body and back from the tail to the head. The gill region, the skeleton, is a network of horizontal and vertical interconnected rods. The fins and tentacles are also supported by the connecting rod. Their central nervous system is a neural tube running along the body, located above the spinal cord but not reaching the end of the spinal cord, wrapped in a protective glue film. Although the Van Xuong looks like a fish, the biggest difference between it and its vertebrates is that it does not have a real head, sensory organs such as smell, sight and hearing, even a skull. The teeth are also something too fictional for them. This animal has only a bunch of elastic “legs” on the head to play the role of supporting the body. The most amazing thing is that it doesn’t even have a heart; instead, it relies on the beat of part of the blood vessel to carry blood. Their musculoskeletal system is less dissociated and typical dissociated. Therefore, muscles can only ensure simple bending movements, consistent with the lifestyle of being buried in the sand. The muscular system consists of many muscles (myomera), arranged from the front end to the posterior end of the body. The muscle segments are intersected by septum by connective tissue (myosepta). The muscles on both sides of the body are arranged alternately with comb teeth together. As a result, when swimming, the Pangasius swim, its body bends along the horizontal plane. Amphioxus is widely distributed in the shallow waters of the ocean, and Qingdao and Xiamen in China are their primary habitats. In addition, there are coasts of Southeast Asia and coasts of California and Florida, Norway, the Mediterranean and Africa. Due to its rich nutrition and delicious taste, Van Xuong fish is considered a delicious traditional dish in Southeast Asia. Van Xuong fish is 3 to 5cm long, the morphology is very strange. The long and flattened body looks almost like a burden. The whole body color is pink, semi-transparent, the parallel longitudinal muscle fibers can be seen. They have no scales, no fins, no vertebrae, and their internal organs are just a rhythmic, rhythmic, complex. No senses like eyes, nose, or ears. There is no differentiation to the digestive tract. Apart from the mouth and throat, just a piece of intestine that leads straight to the anus. Van Xuong fish often follows tidal water to swim in estuaries where the seabed is shallow, almost unable to defend themselves but capable of penetrating into the ground. Their lifespan is about 3-4 years, they often bury half of themselves in the sand, while the other half is exposed to the plankton from the river. Their muscles are less differentiated, so they can only move in water by simple bending movements. When not moving they often bury themselves in the sand. The way of respiration of Van Xuong fish is similar to that of fish. They vibrate to inject capillaries (mouth tassels) to carry the stream of water from the gill slits. The wall of the gill slot has many blood vessels, where gas exchange occurs.

Billions of T. rex have been wandering North America, a group of experts say. Although not a simple task, paleontologists from the University of California (USA) gave the T. rex dinosaur numbers in the Cretaceous period 65 – 98 million years ago. Challenging work Fossils have long been used to improve our understanding of extinct creatures like dinosaurs, but experts suggest that these skeletons are used to calculate densities and levels. Their abundance is a challenge. Director Charles Marshall of the University of California’s Museum of Paleontology is part of the research team. “There is no information available to make an estimate,” he said. If you find an Easter egg in your garden, how do you estimate how many Easter eggs ever existed? It simply cannot be done. You need information from somewhere else, for example, the density of the Easter eggs, how many years they can be found and how many Easter eggs have been placed in the garden. Paleontologist Nizar Ibrahim at the University of Portsmouth (UK) is not involved in the study. “Previously researchers tried to estimate things like the size of the Tyrannosaurus’ habitable area and their basic energy needs, so this is an extension of the work,” he said. before that, including many updates about Tyrannosaurus ”. There are 20,000 T.rex dinosaurs in North America T.rex is predicted to have a lifespan of 28 years. Using fossil records, densities and data from climate models, the University of California team calculated that about 20,000 adult T. rex, living across North America, could exist at the same time. . In a study published in the Journal of Science, researchers say this means that about 2.5 billion T. rex have lived and died over a period of nearly 2.5 million years – a process The dinosaurs live. For the first time, the team also calculated the lifespan of dinosaurs. Using scientific literature and expert opinion, they estimated T.rex’s adult age to be 15.5 years and its lifespan could reach around 28 years. The average adult body weight of this dinosaur is about 5,200 kg and a growth after maturity can make them weigh up to 7,000 kg. From the above estimates, the team concluded that each generation of T.rex lasted for about 19 years and there was a dinosaur for every 100 square kilometers. They determined that, with 20,000 permanent dinosaurs and about 127,000 generations of this species, there would be about 2.5 billion T.rex overall. “The researchers’ approach seems informative, while also pointing to current limits on what can be done,” said Jason C.Poole of the Bighorn Institute of Paleontology (USA). learned from the known “. “I’m sure it opens the door to better focus on questions about population density and what it means over time. So this can really help us understand how animals change over time as it is related to evolution and changing ecosystems, ”said Mr. Poole. The researchers estimated that the population density of T. rex was equivalent to 3,800 carnivorous dinosaurs in an area the size of California, but only 2 in an area the size of Washington DC. . Open up the possibility to find out more information A T.rex dinosaur could have an average weight of 5.2 tons. Meanwhile, the results also allow the authors to determine that only about 1 in 80 million T. rex is preserved as fossil remains. “The big impact of this study may be how rare the fossils are, they represent only a fraction of the individual organisms that ever existed, not to mention the depth of time and the rate. it happened in a few thousand to a million years, ”Mr. Poole said. Study co-author Professor Marshall of the University of California said, “In a way, this is a paleontological exercise of what we can know and how we can know what. there… It’s amazing what we know about this dinosaur so we can calculate more information.Our understanding of T. rex has expanded greatly over the decades. Through more fossils, more analytical methods and better ways of integrating information through known fossils ”. Mr Ibrahim sees other possibilities stemming from this study. There is a lot we don’t know about T.rex’s physiology, behavior, and food environment, he said, but this study offers an interesting approach to estimating abundance and prevalence. conservation of dinosaurs. “I would love to see it apply to the other dinosaurs we know from fossils. Looking at a wide range of dinosaurs, predators and prey, we can better compare dinosaur animal communities to modern ones, ”he said. What we see is superficial, according to Ibrahim, and even with this fascinating research, there is still a long way to go for us to confidently apply these approaches widely in research. save dinosaurs.

Even though there is news of reduced CO2 emissions into the atmosphere in the early stages of a pandemic, the risk of climate change remains evident. New research has shown that, even after a year of decommissioning and production cessation, global greenhouse gas emissions continue to increase at an unceasing rate. To mitigate the worst effects of climate change, the researchers note, humanity needs to focus purposefully on reducing fossil fuel emissions to close to zero, but even less. In that case, humans also need to find ways to further remove greenhouse gases from the atmosphere. Covid-19 is believed to have contributed to change in planetary climate; Source: topnewsrussia.ru The rapidly changing climate is caused by human activities and this is a scientific conclusion. Back in 1988, scientists put the issue of global warming on the agenda, emphasizing that humanity is facing a “climate emergency”. In 2020, 11,000 scientists around the world released a statement with the same name, calling for immediate action. According to the scientific community, our failure to reduce the amount of carbon dioxide (CO2) in the atmosphere will turn unusually hot waves, storms, wildfires and melting glaciers “a daily thing” and could “make the a large area of ​​uninhabitable Earth ”. Researchers noted that the world leaders’ actions against climate change cannot be called enough and effective. At the same time, the media’s response to the Covid-19 epidemic, such as the use of masks and social isolation, illustrated a useful, effective model of action. People should do the same with climate change. Since CO2 has remained in the atmosphere for decades, the longer humans wait for decisive action, the more extreme the weather, and the more likely it is to pass points of no return or out of control. Covid-19 pandemic and global warming A pandemic may have little effect on climate change, but Covid-19 can certainly teach us a lot about the global threats that exist. Recently, researchers from King’s College London have concluded that countries that are better prepared for a climate emergency have much more advantages in dealing with the Covid-19 pandemic. More importantly, the scientists also concluded that countries should treat the climate crisis as a pandemic. Research taking data from 110 countries shows that societies “in which people care about each other” cope better with pandemics. The work highlights the urgent need to invest in both climate action and public health infrastructure so countries can better prepare for similar disasters in the future, as Sciencealert writes. By looking at the social, economic and health measures each country is proposing to deal with the pandemic, the King University researchers found a lack of “social cohesion” in America. and Western Europe led to an increase in Covid-19 mortality. More than 71% of emissions since 1988 are believed to have been generated by 100 of the world’s super corporations; Source: topnewsrussia.ru Last year, the economic slowdown caused by the global pandemic cut CO2 emissions by about 7%, which according to some studies, only 10% of this initial sharp drop was due to air travel. reduction. Another study shows that the Covid-19 pandemic will only cool the planet by about 0.01 ° C by 2030. This is a small difference, but the good news is that if combined, then cut. By investing in fossil fuels, we can avoid warming of 0.3 ° C in the future by 2050. “Increased fossil fuel emissions may not be entirely the cause of the increase in methane concentrations in the Earth’s atmosphere, but a reduction in fossil fuel emissions,” says chemist Ed Dlugokenski. is an important step to climate change mitigation. Reality shows that, even if people around the world decide to stay home, travel less, fly less and consume less, it’s still not a solution, because 71% more emissions since 1988 have been generated by only 100 of the world’s super companies. These are companies and the systems related to these companies need to be changed. Therefore, it will take more than one global pandemic to address the climate crisis.

An image of polluted air was taken on February 13, following the outbreak of the Covid-19 pandemic, in Beijing, China. Photo: Reuters. On April 20, the International Energy Agency said that global CO2 emissions from electricity use will increase by nearly 5% this year. This suggests that an economic recovery from Covid-19 could bring many benefits, except for climate sustainability. The IEA’s 2021 Global Energy Assessment predicts that carbon dioxide emissions will rise to 33 billion tons this year, 1.5 billion tons higher than in 2020, the highest increase in more than a decade. IEA Executive Director Fatih Birol said this year’s increase in emissions this year could be increased by the recovery of coal use in the power sector, which is forecast to be particularly strong in Asia. It will also put pressure on governments to take action on climate change. US President Joe Biden will hold an online summit involving dozens of world leaders this week to discuss climate change ahead of global negotiations in Scotland at the end. this year. Last year, as electricity usage fell due to the Covid-19 pandemic, energy-related CO2 emissions fell 5.8% to 31.5 billion tons, after reaching a peak in 2019 of 33, 4 billion tons. The IEA’s annual review analyzed the latest country data from around the world, economic growth trends and new energy projects. Global energy demand is expected to grow 4.6 percent by 2021, led by developing economies, pushing it above 2019 levels, the report says. Demand for fossil fuels is on the rise in 2021, with both coal and gas rising above 2019 levels. IEA said more than 80% of its forecast for coal demand growth by 2021 will come from Asia, led by China. Coal use in the US and the European Union is also on the rise but will remain below pre-crisis levels.

Berkeley Lab is pursuing negative emission technologies and related research to remove CO2 from the atmosphere. According to Jeffrey Long, senior scientist in the Berkeley Laboratory’s Materials Science Department, UC Berkeley Professor of Chemistry, MOFs are highly porous solid materials that act like a sponge. They are capable of absorbing large amounts of a specific gas molecule, like CO2. A special feature of MOFs is its high internal surface area. Therefore, if properly designed, a small amount of MOF can remove large amounts of CO2 from the flue gases produced during the burning of fossil fuels. “We have shown that MOFs can capture and release CO2, using a much smaller temperature change than is required by other technologies. This offers a great advantage over conventional methods of CO2 capture. Variations of MOF can be effective in removing CO2 from other gas mixtures, including biogas, natural gas and even directly from the air, ”explained Mr. Long. However, this expert emphasized, reducing the cost of direct gas collection is essential, because this process is extremely expensive. The cost of removing CO2 with such a technology is at 500 – 1,000 USD / ton. Therefore, Mr. Long said that in the future, researchers will create more efficient materials. As a result, it helps to reduce costs below 100 USD / ton. Besides, the main issue is the amount of energy required to regenerate the adsorbent. This means that the scientists want to release CO2 in its pure form. As a result, the material can then be reused to capture more CO2. “One of our research goals is to develop materials with high capacity, high capture rate, fast kinetics for CO2 adsorption and low regeneration temperature. At the same time, limit the co-adsorption of water so as not to waste energy on the desorption process “, Mr. Long said. According to the scientist, it is possible to find a way to achieve below $ 100 for each ton of CO2 removed from the air. However, scientists will have to do much of the research needed to achieve that. “We need to really rethink some of the ways materials are designed and understand how to manipulate things like delta-S (entropy) to adsorb CO2, so that less heat is needed to release CO2,” Mr. Long stressed.

Artwork: Getty In an explanatory statement released later, New York Mayor Bill de Blasio emphasized: “We need to attack the biggest polluting corporations, with false advertising about fighting climate change.” According to the head of the New York City Consumer and Workers Protection Agency Lorelei Salas, energy corporations have committed acts of harming consumers’ interests by always advertising only products. “Clean and environmentally friendly” without mentioning, even “hiding” negative impacts on the climate. And this has influenced consumers’ decisions and protecting benefits. profits for oil and gas corporations. This is not the first time New York City has “declared war” on the giants of the oil industry. In early 2018, New York Mayor De Blasio announced the city was suing five fossil fuel companies – BP, Exxon Mobil, Chevron, ConocoPhillips and Shell – to federal court for their roles in Climate Change. At the end of 2019, New York City continued to sue ExxonMobil Group in a climate change issue. Lawsuits are filed with the aim of forcing energy corporations to tell the truth about commercial behavior and the products they sell, according to New York City Law Officer James Johnson. “Consumers have the right to choose different products and many consumers are very concerned about climate change”, added Mr. James Jhonson.

President Joe Biden. Photo: AP Along with the participation of the US, the leaders of the countries have promoted a new commitment to reduce harmful fossil fuel pollution on the first day of the summit organized by the US. However, observers hope video conferencing between senior leaders of countries will look towards new action to deal with climate pollution and as money for the UN meeting in November in Glasgow. . The world will face “dangerous moments” but also “opportunities”, President Biden declared during the online summit to have the participation of 40 world leaders. “The signals are unmistakable. The science is undeniable. The cost of delay continues to rise,” said President Biden. Before the summit, the pledge of President Biden once spoke out to cut 52% of US fossil fuel emissions by 2030. This comes 4 years after the US withdraws from the climate change agreement. The Biden administration this week is outlining a new vision for a prosperous, clean energy America. At that time, factories will focus on the production of advanced batteries and electric cars. At the conference, Japan announced its goal of cutting emissions by 46% and South Korea said it would stop giving public funding to new coal-fired power plants. This is considered an important turning point to persuade China and other countries to limit dependence on coal fuel. Canadian Prime Minister Justin Trudeau said he would increase fossil fuel pollution cuts from 30% to at least 40%. In a report by insurance firm Swiss Re (Switzerland), climate change could cause up to $ 23,000 billion in damage to the agriculture, health and physical infrastructure sectors, as well as to government spending direction. Joining hands to deal with climate change The complicated developments of the epidemic make the climate change summit to be held in an online format. However, the participation of the leaders of the countries shows the joint efforts to deal with the climate change challenges taking place around the world. Chinese President Xi Jinping expressed his determination to cooperate with the US in promoting efforts to cut emissions. “Protecting the environment is about protecting productivity. Promoting a healthy environment is about promoting labor productivity”, President Xi Jinping emphasized. Russian President Vladimir Putin also offers opinions and pushes on efforts to cope with climate change. “Russia is really interested in increasing international cooperation in search of effective solutions to climate change and all other important challenges. Russia is currently the fourth country in number. Large fossil fuel smoke emissions are harmful to the climate. Observers say that efforts to cope with climate change are the driving force for leaders of all countries to push disputes and tensions aside for a good and healthy world. Fossil fuel emissions on earth increase rapidly, according to analysts. The Biden administration’s commitment will require a major effort to address current climate change issues. German Chancellor Angela Merkel is one of several allies that support a return to the United States in response to current climate change. “I am delighted to see that the United States has returned to working with us in climate politics. Because of America’s involvement and we need you to join hands in accomplishing our great goal,” Chancellor Merkel spoke out in her speech at the online summit. Pope Pop Francis is also strong: “I wish you [nước Mỹ] succeed in this great decision to meet, step forward and accompany all the way “. According to scientists, the alarming level of climate change comes from operations at coal plants, car engines and other fossil fuel use. These are reasons that exacerbate the risk of droughts, floods, storms, wildfires and other natural disasters. Leaders of small states and island nations also voiced the serious challenge of rising sea levels and increasing natural disasters. The countries are also calling for international assistance to cut emissions from world powers.

Chinese paleontologists have found ancient insects, snakes, ancient birds and even dinosaur tails in fossil Burmese amber. Thanks to the special preservative properties of amber, these fossils have retained their original shape after 100 million years. One of the dinosaur feathers discovered in the amber piece was damaged by chewing and the markings are similar to the feathers of modern birds with parasitic lice. Feather is one of the types of “special impurities” preserved in Burmese amber, including neck feathers and insect feathers. Not long ago, two pieces of feathered amber from Myanmar attracted paleontologists because through microscopic observations, the researchers noticed some ancient bugs in the feathers. Although these bugs are small and hard to see, paleontologists have found that they have unique and striking habits. The newly discovered insect is named Mesophthirus engeli, revealing the early makeup of the lice ancestor. Mesophthirus engeli has no wings and a body similar to a lice. The team found that they chewed very vigorously through the marks of a dinosaur’s fur. A team of researchers from the Capital Education University of China, the Chinese Academy of Sciences, the Capital Medical Science University, the National Museum of Natural History, and the Russian Academy of Sciences studied the studies. Small insects preserved in amber and discovered this particular beetle. Archaeologists have named this tiny insect Mesophthirus engeli with the genus “Mesophthirus” from the Greek word and the name “engeli” is dedicated to Michael S. Engel, a famous paleontologist. Americans, in recognition of his outstanding contributions to the study of ancient insects. The earliest appearing fur-eating insect was thought to be Megamenopon rasnitsyni. The lice fossils were unearthed in Germany 44 million years ago, according to Chungkun Shih, study author at the Smithsonian Institution’s Museum of Natural History. Researchers also found evidence of Jurassic and Cretaceous parasitic parasites 66 to 201 million years ago. This ancient bug was very small with a length of less than 0.2 mm, so researchers had to use an electron microscope to see its shape. Mesophthirus engeli looks very much like today’s lice, but it has a larger head with black dot-like eyes on the sides and two tentacles with three long spines on top of the head. Mesophthirus engeli can be said to possess a body “three rings as one”, with the head, chest and abdomen equally wide, six feet short, with claws and long spines at the end, can be grasped. This finding suggests that the insect’s feathering behavior has originated at least in the mid Cretaceous period. Although it looks like a lice, the Mesophthirus engeli species is far different from modern lice and lice. Hence, paleontologists established a new ancient taxon of insects – Mesophagous caterpillars. Compared with the body, the mouth of Mesophthirus engeli is very large and strong, two large jaws are serrated, capable of chewing very strongly. In addition, the researchers also found that in the amber pieces containing these ancient bugs all had the presence of feathers and they all existed signs of damage: broken niches formed near the body. feathers and feathers are also broken. The marks of damaged feathers resemble those left by a feather-eating bug after chewing on the feathers. And obviously, the culprit of these traces was none other than the Mesophthirus engeli species. The origin and early evolution of the hairy trait in insects is inherently ambiguous due to the lack of records of Mesozoic fossils – the period of tectonic, climatic and progressive activities. chemical. Blood-sucking insects were found during the Jurassic and Cretaceous periods, but dinosaur fur-eating insects have not been previously reported. The discovery of this ancient feather-eating beetle is of great significance, because it has pushed the history of feather-eating insects to 55 million years, because before the discovery of this beetle, the earliest feather-eating insect. is known to mankind in the Kainozoic era 44 million years ago. Thus, the discovery of Mesophthirus engeli filled the gap in the early evolution of a feather-eating insect. Mesophthirus engeli lived in the Cretaceous period 100 million years ago, this is also an important period of diversity and differentiation of primitive birds and feathered dinosaurs, it can be said that this is also the setting stage. parasitic relationship between feathering insects and their host.

The number of car charging stations is increasing globally and also in Vietnam.

The energy provided for electric vehicles is increasingly clean

The REN21 Global Renewable Energy (GSR) Report of 2020 (Global Multilateral Renewable Energy Policy Network) shows that, over the past 5 years, the renewable energy sector has reached its speed. 3 times higher than electricity produced from nuclear and fossil fuels.

“When the grid becomes ‘greener’, using electric vehicles will be more perfect ”, Gordon Bauer – electric vehicle researcher at the International Council for Clean Transport in San Francisco (USA) said. According to expert Gordon Bauer, the current innovative grid model will help improve the environmental efficiency of electric vehicles around the world.

The evidence is a study by scientists at the Lawrence Berkeley National Laboratory in California (USA) that if all personal vehicles in the US are powered by electricity, each year, the country will lose 46%. greenhouse gas (0.5 gigatons CO2 equivalent) compared to conventional fossil fuel cars.

This is what environmental activists expect. Anne Laurent, president of the All-European Environmental Union, admits the members “have no doubts” about the positive impact this vehicle can have on the planet.

“We do not expect a perfect solution. Therefore, we are delighted that electric vehicles deliver positive environmental indicators“Ms. Laurent said in a report released at the end of 2020.

In Vietnam, green vehicles are also developing with the launch of private cars and VinFast electric buses. And look at “National energy development strategy to 2030, vision to 2045” – with the goal that the renewable energy in the total primary energy supply will reach 15 – 20% by 2030 and increase to 25-30% by 2045 we have the right to hope for a “green future, clean air” when clean cars are powered by clean electricity.

Electric vehicle batteries are too expensive to be … garbage

In addition to generating electricity, environmental activists have been concerned about the fate of electric vehicle battery blocks after they have run out of “trumps”. Elon Musk was the “victim” of this wave of protest. But in fact, electric car batteries can not be thrown away because … too expensive, even after the expiry date.

The reason is that the prices of cobalt, lithium, nickel and the metals used in lithium-ion batteries have skyrocketed as the electric car race intensifies between manufacturers across Asia to Europe and the US. Therefore, all electric car manufacturers are researching and announcing solutions to handle expired batteries with battery recycling technology.

“To meet electric vehicle battery demand in the next 10 years, the industry will need 1.5 million tons of lithium, 1.5 million tons of graphite, 1 million tons of nickel and 500,000 tons of manganese. Today, the world produces less than a third of that material ”Sam Jaffe, CEO of Cairn ERA, an energy consulting firm in the US, told CNBC.

Some studies show that recycling can recover between 95 and 98 percent of the nickel, cobalt, copper, aluminum, and more than 80 percent of the battery’s lithium. Ms. Celina Mikolajczak, Vice President of Battery Technology and Technology at Panasonic Energy North America, said that the battery recycling industry will be a billion-dollar land with the development of electric vehicles.

“There are so many benefits to recycling and it would be really stupid if we didn’t take advantage of the old battery cells’ ability to make the next generation.”Ms. Celina Mikolajczak confirmed.

This excellent solution not only eliminates the worry of running out of production materials, but also removes electric vehicle batteries from the burden of the environment.

There are more than 50 companies around the world engaged in the recycling of lithium-ion batteries of varying sizes, most of them concentrated in China (more than 20 companies), followed by Korea (6 companies), followed by the EU, Japan, Canada and the US. Even global tech giant Amazon hasn’t overlooked this potential by investing $ 2 billion in Redwood Materials, a battery recycling startup founded by former Tesla chief JB Straubel. Redwood Materials is also responsible for recycling electric vehicle batteries for Tesla.

In addition to recycling batteries for reuse for electric vehicles themselves, a series of projects to utilize old batteries have been implemented recently by car manufacturers. Toyota has a project to connect old electric vehicle batteries with solar panels to power 7-Eleven stores in Japan; Nissan is using old batteries to power the small robots; Renault is working with its partners to introduce static energy storage systems made of old electric vehicle batteries … Other car manufacturers such as Audi, BMW, Lucid Motors or Proterra … are also incorporating reusable principles into their designs. the battery.

“We believe that the ‘second life’ battery will become an independent business and cannot be disposed of as trash.”, Weiland Bruch, BMW spokesman forecasts.

When the final concern was that electric vehicle batteries turned into environmental waste were completely eliminated – it’s easy to understand why green cars are supported by environmental activists around the world. And that will also be the green future that we need to move towards to escape the country’s “scandal” of the “two-wheeled gas factories” that international indicators set for Vietnam.
