Melting glaciers, ancient virus or long-term virus, is the emergence of COVID-19 related to global warming?

At present, global warming has long been * * * knowledge, which has a lot to do with human activities. Since the industrial revolution, science and technology and productivity have improved, the population has skyrocketed, and human needs have increased day by day. Humans rely too much on fossil fuels and emit a lot of greenhouse gases such as carbon dioxide into the atmosphere. Greenhouse gases, like a warm quilt, can absorb the sun's radiation and store it, which hinders the heat dissipation of the earth and makes the global average temperature rise day by day. In order to curb this trend, some responsible countries have taken measures to reduce greenhouse gases.

Humans began to record the temperature from the middle of19th century. According to research, the thawing period of ice and snow in the northern hemisphere was earlier than that of 150 years ago, but the frost started later, and the global average temperature rose by about 0.6℃ in the 20th century. Do not underestimate the change less than 1℃. The average temperature rises by 65438 0℃, which means that the extreme temperature will fluctuate several degrees.

It is generally believed that global warming is caused by human burning fossil fuels. However, there are also views that it is caused by the activities of the sun. The temperature of the earth is really not constant. In the 4.5 billion-year history of the earth, there have been many climate fluctuations. The Ice Age more than 60 million years ago is the best witness. The activities of the sun can really affect the climate of the earth. But for today's human beings, there are 7.8 billion people on the whole earth, and we can't afford this kind of tossing. Extreme drought alone is enough to cause large-scale crop failure and make people starve, even starve to death.

Greenhouse gases do cause global warming, and Venus is the best example. According to the monitoring, the content of carbon dioxide in the atmosphere is increasing year by year, which will inevitably have an impact on the global climate, and human beings must be prepared for extreme climate change. The rise of carbon dioxide has acidified the ocean, and a large area of coral reefs has been bleached and died.

Global warming will redistribute global precipitation, melt glaciers or frozen soil and raise sea level, which will threaten the balance of ecosystem and human survival. The land is divided into three parts and the ocean is divided into seven parts. The heat energy brought by the temperature rise is provided to the air and the ocean, which will generate huge kinetic energy, thus forming bad weather.

There are a lot of glaciers in the north and south poles of the earth. Global temperature rise will melt the polar ice sheets, and some low-altitude areas will be submerged. Rising temperatures will also soften frozen soil. But what is more worrying is the bacterial virus hidden in the ice. When it comes to bacteria and viruses, we have to mention plague, which is a highly contagious disease. At present, COVID-19 has caused a serious epidemic of infectious diseases in human history, and almost no one in the world has been spared.

Viruses and bacteria are tiny microorganisms that are invisible and intangible to the naked eye. Viruses, in particular, are extremely simple in structure, between living things and non-living things. If they are not parasitic in other organisms, they are completely a pile of chemicals.

Some viruses or bacteria are extremely tenacious, can hibernate like animals at low temperature, and become active again when the temperature is right. The structure of virus is extremely simple, and low-temperature freezing generally does not destroy its molecular structure. Scientists are studying cryonics technology. In contrast, these microorganisms are very small and easier to achieve. For example, sperm and eggs can be frozen at low temperature for many years and can also be used for fertility. Some viruses and bacteria have been frozen for decades or hundreds of years, but they still have the ability to mutate and infect after thawing, and there are potential risks.

Most parts of Siberia, Russia, are frozen all the year round, and the dead animals buried under the ice sheet don't even rot. No one knows whether there are ancient viruses hidden under the dead animals or frozen soil. If global warming melts the frozen soil, those bacteria and viruses will become active again and return to nature. I wonder what impact it will have on mankind. Siberia is also inhabited, and some people who died of infectious diseases are buried under the ice sheet, but these bacteria and viruses may not have died, which means that germs hundreds of years ago may ravage the world again.

It has been found that COVID-19 originated from nature. However, it is not clear whether the emergence of COVID-19 is related to global warming. Even in today's accelerated extinction, many species can still be found every year. There are too many kinds of viruses in nature, and viruses, as a microorganism, are highly variable and often spread across species, and many new viruses will inevitably appear in the future. Without vaccine and drug resistance, it will cause catastrophe. When and where did COVID-19 originate? No one knows now. Maybe it has existed in nature for a long time, and it has not been transmitted to humans until now.
