Climate warming and frequent extreme weather.

There are many reasons for extreme weather, and we cannot unilaterally say that climate warming is only one of them.

The increase of greenhouse gas concentration, global warming, El Nino phenomenon, the dynamic movement of the earth itself, human intervention in nature, the change of solar radiation, the deviation of the earth's orbit and the interaction of internal and external factors are all reasons for the increase of extreme weather frequency. Scientists also believe that the earth has a natural feedback mechanism to climate change, which can expand or reduce external positive and negative forces to maintain the stability of the earth's climate system. Without such a mechanism, the climate system may be unstable. However, if the external pressure is too large, it may lead to the collapse of the climate system, so disastrous extreme weather and climate events will occur frequently.

Extreme weather is caused by airflow, internal factors of the earth and, of course, human factors. The most important human factor is the increase of carbon dioxide concentration, which intensifies the greenhouse effect and produces strong convective weather and strong convective weather. Another reason is the heat island effect. The more serious the heat island effect is, the more air rises and the more air sinks nearby, which will lead to a convection. This couplet is particularly strong.

In the face of frequent bullying disasters, human beings have taken action. Although the Copenhagen conference did not reach a substantive and binding agreement, it served as a warning to mankind. Emission reduction, low carbon and ecology have become essential keywords in our lives. How do humans save themselves in the face of frequent disasters? The most fundamental thing is to protect the ecology with low carbon and reduce industries with high energy consumption. The most important thing is to study alternative energy and renewable energy, reduce the bearing pressure of the earth, and restore the earth's climate to the ability of natural adjustment.
