Why is it so hot this year? How long will it be hot?

Due to global warming, it is impossible to estimate how long it will be hot.

The main reason for the hot weather this year is global warming. Due to the increase of greenhouse gases such as carbon dioxide and methane in the atmosphere caused by human activities, the global temperature is rising continuously, which makes the summer temperature in many places much higher than the average level. As for how long this heat will last in the future, it is a difficult problem to predict the weather, and many complicated climatic factors and changing trends need to be considered.

Global warming refers to the phenomenon that the average temperature of the earth rises, which leads to climate change and the destruction of natural ecosystems. Global warming is mainly caused by the increase of greenhouse gas emissions caused by human activities.
