LE FIGARO. – Why should the average temperature increase be greater in the coming months?
Cathy CLERBAUX. – There is a convergence of factors that all point in the same direction for the next eighteen months. The underlying trend is of course linked to the accumulation of greenhouse gases in the atmosphere. Added to this is the drop in automobile pollution (linked to the deployment of electric vehicles in Europe, the United States and China), whose aerosols shield solar radiation.
These two phenomena contribute +1.2°C to the rise in future temperatures. Also, the solar cycle (about ten years old, editor’s note) approaches its maximum. In addition, the recurring climatic event El Niño (a surface temperature anomaly in the Pacific), which tends to warm the planet, is taking hold. Finally, the violent eruption in January 2022 of the Hunga Tonga submarine volcano sent around 150 million tonnes of steam…
