Why is it so sultry these days?

Landlord, the reason why the weather is so sultry: The most important thing is that due to global warming, the greenhouse effect is intensified, leading to frequent extreme weather, which is easy to produce extremely strong precipitation and cause floods; It is easy to cause no rain for a long time, resulting in extreme drought; Or cause extremely long-term high temperature weather, forming a heat disaster; For example, the continuous precipitation in Northeast China in May, June and July this year, the freezing rain and snow disasters in Guangdong and southern Hunan in early 2008, and the continuous high temperature in North China this year are the best examples.
