Heat waves like the current one they will increase by 30% in the next few years and the main cause is to be identified in the greenhouse gases emitted by man: this is indicated by a new study coordinated by Jiayu Zheng And Chunzai Wang ofChinese Academy of Sciences and published in Advances in Atmospheric Sciences made with the aim of evaluating the human impact on atmospheric circulation.

Exceeding 40 degrees, the July 19, 2022 has gone down in history as the hottest day ever recorded in the UK but forecasts indicate that the strong heat wave that hit a large part of the northern hemisphere, including Italy, is destined to repeat itself several times in the coming years. To try to better understand the dynamics behind these extreme events, Chinese researchers wanted to apply the current models of atmospheric circulation prediction to analyze what happened in 2021, another violent heat wave that hit the North in particular. America, especially the Pacific side, causing about 1,500 deaths, massacres of marine animals and huge fires. According to the authors, the models clearly indicate that the main reason for these heat spikes are clearly greenhouse gases that alter the ‘normal’ flows of atmospheric currents.

“If appropriate measures are not taken – commented Wang – the probability of extreme heat waves will increase and will have a further impact on the ecological balance, as well as on sustainable development at a social and economic level”.
