Frequency of heavy rain in Northern hemisphere may increase by 15% due to global warming - scientists

04 july 2023

Climatologists from the United States found that each increase in average temperatures by one degree Celsius raises the frequency of heavy rains in the mountains of the Northern hemisphere by about 15%, as reported by the Lawrence National Laboratory.

Scientists noted, in particular, the risk for the Russian Chukotka and Kamchatka. Researchers believe that, if the temperature rises by three degrees or more, the number of showers in these areas may increase several times by the end of the century. And this will dramatically increase the likelihood of natural disasters.

American climatologists studied the data of observations of the climate in the mountains from 1950 to 2019.

The climate model has shown how precipitation levels in the mountainous regions of the Northern hemisphere may change before the end of the XXI century.
