Arctic ice melting to enhance El Nino effect and change world climate

03 april 2024

The rapid melting of the Arctic ice will lead to an increase in the El Nino natural phenomenon's scope, which is associated with the occurrence of dry periods, severe storms and floods around the world.

In addition, researchers from universities in the United States and China warned of an ice-free Arctic summer in 2040, RuNews24.ru reports.

Scientists have analyzed the effect of Arctic ice melting on El Nino. According to the researchers, the amplitude of the natural phenomenon directly depends on the rate at which the Arctic ice is shrinking.

At the same time, the area of sea ice has already decreased by 12% over the past half century. Experts fear that the summer of 2040 will be the first ice-free summer in the history of the Arctic due to this development.
