Article’s title: « Des régions du Brésil en alerte face à une sécheresse de l’air historique »
The article discusses an unprecedented air dryness in several regions of Brazil, particularly in the northeastern states. This dryness is linked to a positive Indian Ocean Dipole (IOD) event, which has caused a decrease in rainfall and an increase in temperatures. Consequently, vegetation and water resources are severely affected, threatening agriculture and increasing the risk of fires. According to experts, this situation could worsen in the coming months due to the La Niña phenomenon.
