should we fear “unprecedented heat waves” in 2023?

Meteorologists fear exceptionally high temperatures in the world for the years 2023 and 2024, reports TF1, this Tuesday, January 17.

The highly probable return of El Niño worries all climatologists. This oceanic phenomenon which warms the waters of the Pacific could indeed cause historic heat waves in the world in 2023 and 2024, indicate our colleagues from TF1, Tuesday January 17.

El Niño was already at the origin of the absolute temperature record recorded in 2016, with 1.2°C more than in the pre-industrial era.

In the coming months, global warming could this time reach the very worrying mark of +1.5°C, reports The Guardian. According to Adam Scaife, head of forecasts at the Met Office, the British national meteorological service, this threshold of +1.5°C has “a 50% chance of being crossed in the next five years”.

Forest fires and floods

“With climate change, the impacts of El Niño events will intensify”alert to the British daily Adam Scaife, which predicts “unprecedented heat waves during the next El Niño” in 2023-2024. Australia and Indonesia would be directly affected by warming waters. Periods of drought and forest fires could therefore increase. Conversely, the United States and East African countries would be at risk of flooding. New disasters are therefore to be feared after a year 2022, the hottest ever observed in France, particularly marked by exceptional meteorological phenomena.
