Meteorologists warn that the era of climate crisis has arrived. What are the main factors related to the temperature rise?

The rising temperature is related to the melting of glaciers, marine glaciers and land plateau glaciers. Melting oceans and polar glaciers will lead to rising sea levels and endanger coastal homes. The melting of plateau glaciers will lead to mudslides, dammed lakes, dam breaks and floods. But these are superficial phenomena, and the harm of glacier melting is far more than that, and it can even be said that it is extremely serious. If the temperature of the house is too high, we can sprinkle a bucket of ice on the ground to cool the house. Similarly, why are glaciers and ice sheets melting everywhere? They actually offset the excessive heat released by human beings and stabilize the temperature of the earth.

Secondly, automobile emissions are also one of the factors that increase greenhouse gases. Since the advent of the automobile, the whole world automobile market has been dominated by gasoline vehicles, and this situation has lasted for more than one hundred years. With more and more people owning cars, the future car emissions will only bring more and more burdens to the atmosphere, natural greenhouse gas emissions. For example, cows release methane by burping and farting. Microorganisms in swamps also release methane and other greenhouse gases through decomposition.

Furthermore, it is caused by the chaotic climate and frequent extreme weather. In many parts of the world, the once-in-a-year or even once-in-a-century hot weather even seriously threatens the lives of residents. The heat energy brought by global warming and rising temperature will provide great kinetic energy for the air and ocean, thus forming large or super-large natural disasters such as typhoons, hurricanes and tsunamis. In inland areas, the increase of air humidity will aggravate the smog phenomenon.

We should know that global warming potential (GWP) is an index to measure the impact of greenhouse gases on global warming. The ability to cause global warming in a period of time by comparing the size of a specific greenhouse gas with the same mass of carbon dioxide. For example, on the time scale of 100, the GWP of methane is 25, which means that the ability of methane and carbon dioxide with the same mass to cause global warming during 100 is 25 times. On the century scale, the GWP of SF6 is as high as 22,800, which is a typical gas with high GWP.
