Why is it so hot this year?

The reasons for the heat are as follows:

1, global warming:

Global warming is the climate background of frequent high-temperature heat wave events in the northern hemisphere. The main cause of global warming is burning fossil fuels such as oil and coal.

2. Persistent La Nina events:

La Nina phenomenon is contrary to El Niñ o phenomenon, that is, the sea surface temperature in the cold water area of the equatorial Pacific Ocean drops abnormally.

As the saying goes, "the mind is calm and naturally cool", keep a quiet and peaceful mood, eat light food, eat less spicy food, and don't blow air conditioners often in hot days. It is easy to get air conditioning disease. Proper sweating is good for health.
