Why is the weather bad this year?

Nowadays, the weather is getting worse and worse mainly because of global warming caused by human beings. Since 1970, the global temperature has risen by an average of half a degree Celsius, mainly because a large number of greenhouse gases have been discharged into the atmosphere. Causing some extreme heat waves, droughts and other extreme weather events. Besides, there is little rainfall now, which makes the "warm" weather worse.

Scientists all over the world know that more than 90% of climate change may be the responsibility of human beings, and the decisions and choices made by human beings today will affect the direction of climate change. Today, the earth is hotter than it was in the past two thousand years. If the situation continues to deteriorate, the temperature of the earth will climb to the highest level in two million years by the end of this century.

In the past, extreme weather "once every few decades" or even "once in a hundred years" became more and more common.
