Previously, UN researchers confirmed that climate change is increasing the severity and duration of heat waves, which in some areas can occur throughout the year. According to Thursday’s Korea Times (24/8/2023), recent headlines have often been dominated by episodes of extreme heat, from the “hot dome” phenomenon that affected much of Europe to wildfires. caused by high temperatures in Greece. , Spain, Canada and Hawaii, as well as rising winter temperatures in South America.

According to John Nairn, extreme heat expert at the UN’s World Meteorological Organization (WMO), heat waves now come earlier, last longer and are more intense.

“This is the immediate and fastest result of global warming that we have observed in weather dynamics,” Nairn said, adding that this phenomenon was in line with scientific projections.

“People seem to take these symptoms lightly. Scientists have already predicted these events. This is not the end (of the heat wave), these events will only get worse and happen more frequently,” said he indignantly.

One of the factors, according to him, is the impact of global warming which causes a decrease in the strength of the global jet stream, namely the flow of air at a height of the Earth’s atmosphere.

As the jet stream becomes slower and more unstable, the weather system stays in one area for a longer period. “It is possible that one summer we will have a prolonged heat wave and temperatures will continue to rise unabated as the flow stagnates,” Nairn said.
