Extreme weather in Chongqing
The cause of extreme weather. In the 4.6 billion-year history of the earth, the movement of the earth's plates has a great influence on the earth's climate. At the same time, the earth's orbit around the sun will change, which will make the earth enter the big and small ice ages. There have been four major ice ages in the history of the earth, each with an interval of about 200 million to 300 million years, and each ice age will have a fluctuating trend of rising first and then falling. Humans have just been in the fourth ice age cycle, and the fourth Great Ice Age began 2-3 million years ago, about? It will take 90,000 years to enter the freezing period.
Since the industrial revolution hundreds of years ago, the burning and development of fossil fuels have led to the increase of greenhouse gases such as carbon dioxide released into the atmosphere. When the emission of greenhouse gases such as carbon dioxide doubles, the global temperature will rise by about two degrees, and the highest can reach about five degrees. The increase of temperature will directly affect the air flow and air pressure difference. This difference will form typhoons, tornadoes, heavy rains and hail.
The influence of extreme weather. The influence of greenhouse gases on the earth is enormous, which will not only cause local extreme weather anomalies, but also lead to rising temperatures, which will lead to the melting of global ice and snow, including the permafrost in the Qinghai-Tibet Plateau, the North and South Poles and the Northern Hemisphere. The rise of sea level will accelerate the extreme change of weather. Although the greenhouse effect counteracts the impact of the ice age on human beings, with the decrease of human population and the self-adjustment of the earth, the environment of the earth will be rebalanced and the largest ice will appear.
