The Arctic heat wave breaks records again. If climate warming causes continuous precipitation, can humans withstand it?
Global warming has become a commonplace topic. In the past few years, the temperature of the earth has frequently broken records, which has to arouse our attention. Even the North Pole, which is known for its coldness, experienced extreme high temperatures just a few days after the summer solstice.
Recently, according to the data returned by the Sentinel 3A and 3B satellites of the European Space Agency's Copernicus program, the Siberia region is suffering from a heat wave, where the surface temperature has almost reached 35 ℃, and the hottest is Verkhoyansk. Town, where the temperature reached 48 ℃. It is worth noting that summer has just begun, and there are still more than two months left, and the temperature may continue to hit new highs.
Looking at previous data, it was found that the coldest and hottest temperature records in the Arctic Circle were all set by the town of Verkhoyansk, at -67.8°C and 37.8°C (set in 2020), with a temperature difference of an astonishing 105.6°C. The frequent occurrence of extreme temperatures in the Arctic Circle has also woken us up. The rate of global warming is accelerating, and if no attention is paid, it may lead to catastrophic consequences.
Heat waves caused by high temperatures have made the Arctic Circle extremely dry and are prone to wildfire disasters, which occur almost every year. Wildfires in the Arctic Circle will produce more carbon dioxide and increase the greenhouse effect. In 2020 alone, the fires in the Arctic Circle have released about 250 million tons of carbon dioxide.
In addition, some permafrost layers in the Arctic are still melting at an accelerated rate, and some ancient bacteria and viruses that have been frozen under the ice will also reappear as the permafrost melts. No one knows that the recovery of these bacteria and viruses will bring mankind. What are the consequences.
As global temperatures increase, it is sure to trigger more and more frequent rainfall. Historically, there has been a record of continuous rainfall for 2 million years on the earth, which is called the Carnian flood event. The heavy rain that lasted for 2 million years caused the extinction of many low plants, caused a large number of herbivores to disappear due to lack of food, and affected the entire earth's ecosystem. About 90% of the creatures were extinct because of this rainfall.
After the rains, tall trees occupied the earth's surface, ushering in the dinosaur age when dinosaurs prospered.
If global warming intensifies, and the high temperature causes frequent rainfall to trigger the Carnian flood event again, can human beings afford it with the current strength?
If continuous rainfall occurs on the earth, it will inevitably cause flood disasters. Many low-lying cities will be relocated as a whole, affecting some human life and production activities. However, these are not the most important ones. The most important thing is the impact of continuous rainfall on plants. The Carnian flood event led to the extinction of a large number of low plants and herbs, and human food crops happen to be low plants. Continuous rainfall will lead to the failure of global food crops, and human beings are faced with the dilemma of no conventional food.
In addition, continuous rainfall can easily lead to a higher probability of disease outbreaks. After flooding into buildings, some items will become moldy and mold will affect air quality. People living in humid environments will also be more prone to asthma and some respiratory diseases. .
As the rainfall continues, due to the inability to adapt to the environment, lack of food, medical care and other problems, the population of the earth will drop sharply, bringing many unforeseen troubles to human beings, and may even cause human extinction in serious cases.
