L\u2019Organisation m\u00e9t\u00e9orologique mondiale pr\u00e9voit le retour d\u2019El Ni\u00f1o pour la fin de l\u2019ann\u00e9e 2023. Ce ph\u00e9nom\u00e8ne m\u00e9t\u00e9orologique cyclique, qui entra\u00eene une hausse des temp\u00e9ratures, inqui\u00e8te. Conjugu\u00e9 \u00e0 l\u2019impact du r\u00e9chauffement climatique d\u2019origine humaine, il pourrait provoquer de nouveaux records de chaleur.<\/p>\n\n\n\n
Le ph\u00e9nom\u00e8ne n\u2019est ni inconnu ni anormal. Naturel et irr\u00e9gulier dans ses fluctuations, de retour tous les deux \u00e0 sept ans, El Ni\u00f1o est pressenti pour refaire un tour de chauffe d\u00e8s 2023.<\/p>\n\n\n\n
L\u2019Organisation m\u00e9t\u00e9orologique mondiale (OMM) des Nations unies (ONU) estime \u00e0 80% les chances de formation du ph\u00e9nom\u00e8ne d’ici la fin septembre. \u00ab Nous avons besoin de deux ou trois mois de plus pour avoir une id\u00e9e plus fiable de ce qui va suivre \u00bb, a pr\u00e9venu Alvaro Silva, un consultant \u00e0 l’OMM.Le cas \u00e9ch\u00e9ant, il succ\u00e8dera \u00e0 une p\u00e9riode de trois ans, chose rare, de son pendant, La Ni\u00f1a, p\u00e9riode m\u00e9t\u00e9orologique au cours de laquelle la temp\u00e9rature des oc\u00e9ans baisse et, par cons\u00e9quent, celle de l\u2019atmosph\u00e8re terrestre aussi.M\u00eame avec ce \u00ab frein temporaire \u00e0 la hausse globale des temp\u00e9ratures \u00bb, les huit derni\u00e8res ann\u00e9es \u00ab ont \u00e9t\u00e9 les plus chaudes jamais enregistr\u00e9es \u00bb, a toutefois point\u00e9 le secr\u00e9taire g\u00e9n\u00e9ral de l\u2019OMM, Petteri Taalas. Et l’ann\u00e9e 2022 marqu\u00e9e par de multiples catastrophes naturelles.<\/p>\n","protected":false},"excerpt":{"rendered":"
