Millions of Chinese called to stay at home because of a phenomenon

Several cities in China are on red alert on Monday due to the heat wave hitting the country, where tens of millions of people have been asked to stay at home.

Extreme heat waves, sometimes deadly, have affected different places on the planet in recent months, such as Western Europe in July and India in March-April.

According to scientists, climate change has made heat waves more frequent, a phenomenon that should increase with the expected rise in temperatures in the coming years.

The country is calling on millions of residents to stay home as the power system is under pressure.
