Why is the weather getting warmer?

Because of a large number of greenhouse gases, such as carbon dioxide, methane, refrigerants and so on. Is injected into the atmosphere, which blocks the sunlight/heat reflected back to outer space after entering the surface-the so-called greenhouse effect. Accumulate and make the earth gradually warm. Coal-fired power plants, a large number of cars, etc. Are sources of large amounts of carbon dioxide. The decomposition of biological waste will produce methane (especially in large farms). After the refrigerant in the refrigerator air conditioner is recovered, the staff is not responsible for releasing it into the atmosphere, and the refrigerant factory is even more problematic. (The destructive effect is 17000 times that of carbon dioxide). Warming causes the frozen layer to melt. For example, in the permafrost of Siberia, glaciers began to melt, releasing methane (methane gas) produced by the decay of animals and plants that have been frozen and deposited for millions of years. This amount is particularly large, and the earth will accelerate warming.
