Why is it so hot this summer?

The reason why the temperature is so hot is global warming.

Global warming: high temperature and drought have occurred this year. Although the global climate changes periodically, local special weather systems, such as tropical high pressure climate and heat island effect, are mainly caused by global warming. According to the report of the World Meteorological Organization, the global high temperature this summer is the result of global climate change. Under the climate background of global warming, it is expected that extreme high temperature will appear more frequently and intensively in the future. If greenhouse gas emissions continue to increase, the greenhouse effect will rise even more.
