Grass grows on Mount Everest, methane erupts in the North Pole, and the temperature in the South Pole is 20 degrees. Will Hawking's prediction come true?

In the summer of 20 19 in the northern hemisphere, heat waves hit many parts of the world. In July of that year, the global average temperature was1the highest in the same month since the temperature was recorded for 40 years, which was nearly 1℃ higher than that in July before 100. In fact, according to some signs on the earth, scientists speculate that this is the hottest time in two thousand years.

This is not the only phenomenon of global warming. When the southern hemisphere entered the summer in 20 19, a large-scale mountain fire broke out in Australia for several months, during which more than 10 billion animals were killed. One of the main reasons for this fire is that the weather has become dry and hot due to global warming.

In 2020, there have been many high temperatures over the same period in the world.

Everest grass

For a long time, the area above 6000 meters above sea level of Mount Qomolangma belongs to the glacier belt covered with snow and ice, where there are snow all year round, glaciers everywhere and nothing grows. However, plants have been found in the ice-covered glacier belt of Mount Everest, which has exceeded the limit growth environment of plants recognized by human beings. According to years of satellite observation data, the vegetation coverage area at the foot of Mount Everest has increased significantly, especially in the range of 5000 meters to 5500 meters above sea level. The above phenomenon is probably caused by global warming.

Arctic methane explosion

There is a lot of methane under the permafrost in the Arctic. With global warming and rising temperature, the permafrost in the Arctic began to melt gradually, which will lead to a large amount of methane being released into the atmosphere. The United States Space Agency (NASA) has monitored that millions of methane release points have appeared in the Arctic permafrost.

As we know, the main reason for the global temperature rise is that humans have released a lot of greenhouse gases, mainly carbon dioxide, into the atmosphere. At present, the concentration of carbon dioxide in the atmosphere has increased by 40% compared with that before industrialization, and the global average temperature has increased by 1 degree. Methane is also a greenhouse gas, and its warming capacity is 2 1 times that of carbon dioxide.

Therefore, if the global temperature continues to rise, methane in the Arctic permafrost will be released continuously, which will aggravate the greenhouse effect and lead to further global temperature rise. In turn, this will further promote the release of methane, thus causing a vicious circle of global warming.

The Antarctic temperature exceeds 20℃

As the other pole of the earth, the Antarctic has been frozen for many years, and the average temperature there is 20 degrees lower than that of the North Pole. The average temperature in Antarctica is -25℃, and that in coastal areas is-18℃. On February 9 this year, scientists measured a record high temperature in the Antarctic Peninsula, with the temperature as high as 20.8℃. There is no doubt that the record high temperature in Antarctica is also a microcosm of global warming.

Locust plague in East Africa

At the beginning of 2020, the worst locust plague broke out in East Africa in decades. Hundreds of billions of locusts even flew over the Red Sea, wreaking havoc in many parts of Asia. The cause of this locust plague may be climate change caused by global warming. The El Nino phenomenon in the Indian Ocean makes the climate in East Africa abnormal. In the winter of 20 19, the rain continued and the vegetation grew in large quantities, which prompted the locust to multiply in large numbers and eventually led to locust disaster.

hawking prophecy

In fact, Hawking was worried that global warming would lead to abnormal climate change and threaten human survival on the earth. Coupled with the potential fatal threats from the universe, such as asteroids and gamma-ray bursts, Hawking believes that the earth may become unsuitable for human survival in the future, and we should go to the universe as soon as possible to find a second planet where human beings can live.
