The continuous development of global warming has brought a series of hazards to mankind. It will not only raise the temperature of the earth, but also lead to the accelerated melting of glaciers on the earth. At present, both of these problems make scientists feel sad. In 2020, historical high temperatures appeared in many areas, and the temperature in Antarctica exceeded 20℃ for the first time.
Not only did the Antarctic temperature hit a record high, but in 2020, the temperature in the United States also set a high temperature record since 107. 19 13, the temperature in Death Valley in California reached 56.7℃, and in August 2020, the temperature in Death Valley was 54.5.
Besides, it's not just Death Valley that has a high temperature climate. A certain area in California and Jin Man, Arizona both broke the record of high temperature in the past decades. However, the frequent occurrence of high temperature climate is also a great test for human beings.
The appearance of high temperature climate has accelerated the melting of the earth's glaciers. In 20 10, a huge iceberg with a size of 2,900 square kilometers in Antarctica cracked, which means that Antarctic glaciers are constantly decomposing, and all creatures living in Antarctica will face the problem of foraging, and many of them are already facing extinction. A research report shows that from 20 1 1, the number of penguins has decreased from 16000 to 10000!
In addition, the Arctic ice sheet has disappeared. The last complete ice shelf in northern Canada, the Milne Ice Shelf, has collapsed. In just two days at the end of July, 40% of the glaciers have disappeared, and the two Arctic ice sheets in Canada have completely disappeared, so the melting speed of the Arctic glaciers is far beyond our imagination.
Professor Weidham, a famous British marine expert, said that the sea ice in the Arctic Ocean is shrinking rapidly and will disappear completely in just a few years, so it will be difficult for Arctic creatures to board the ice floes for food and eventually die. Scientists also say that if all the glaciers in Greenland melt, the sea level will rise by 7 meters!
These problems not only lead to the deterioration of the earth's environment, but also threaten human survival. Because the sea level is still on the rise, it will directly affect the land where human beings live. The coastline is rising, devouring the land, and coastal cities will face the crisis of being swallowed up by the sea in the future!
Nowadays, with the development of global warming, the situation facing mankind is also very critical. If human beings don't want to be swallowed up by the ocean, then we must improve the global environment and alleviate global warming. So what else do you want to say about this?
