Why is the weather always so abnormal recently?

The fundamental reason is that global warming has aggravated the instability of the climate system. Global warming will change the global atmospheric circulation situation and affect the local climate through the interaction between ocean and atmosphere, land and atmosphere. Global warming causes extreme weather and climate events such as rainstorm, flood, drought, typhoon, high-temperature heat wave, cold wave and sandstorm to occur frequently in some areas, and their intensity is enhanced.
