La temp\u00e9rature moyenne mondiale de l’air en surface a atteint 16,96 \u00b0C, soit l\u00e9g\u00e8rement plus que le pr\u00e9c\u00e9dent record d’environ 16,95 \u00b0C \u00e9tabli en juillet 2023. Ce chiffre est sup\u00e9rieur de 0,85 \u00b0C \u00e0 la moyenne des temp\u00e9ratures pour un mois d’ao\u00fbt sur la p\u00e9riode 1991-2020, et de 1,65 \u00b0C au niveau pr\u00e9industriel estim\u00e9 pour la p\u00e9riode 1850-1900.<\/p>\n\n\n\n

Il s’agit du premier mois depuis novembre 2025 durant lequel la temp\u00e9rature mensuelle moyenne mondiale a d\u00e9pass\u00e9 le niveau pr\u00e9industriel de plus de 1,5 \u00b0C.<\/p>\n\n\n\n

L’Europe occidentale a \u00e9galement connu son \u00e9t\u00e9 le plus chaud jamais enregistr\u00e9. Une succession de vagues de chaleur exceptionnellement pr\u00e9coces, persistantes et intenses depuis mai a fait grimper la temp\u00e9rature moyenne de juin \u00e0 ao\u00fbt au-del\u00e0 du pr\u00e9c\u00e9dent record \u00e9tabli en 2003.<\/p>\n\n\n\n

Les temp\u00e9ratures oc\u00e9aniques ont \u00e9galement atteint des niveaux records. La temp\u00e9rature moyenne de surface de la mer dans les oc\u00e9ans situ\u00e9s entre 60 degr\u00e9s de latitude sud et 60 degr\u00e9s de latitude nord a atteint 21,07 \u00b0C en ao\u00fbt, soit la temp\u00e9rature la plus \u00e9lev\u00e9e jamais enregistr\u00e9e pour ce mois.<\/p>\n\n\n\n

Les temp\u00e9ratures \u00e0 la surface de la mer sont rest\u00e9es exceptionnellement \u00e9lev\u00e9es sur une grande partie du Pacifique tropical, o\u00f9 les conditions li\u00e9es au ph\u00e9nom\u00e8ne El Nino se renforcent et pourraient \u00e9voluer, au cours des prochains mois, vers l’un des \u00e9pisodes les plus puissants jamais enregistr\u00e9s.<\/p>\n\n\n\n

Les donn\u00e9es montrent que le changement climatique est \u00e0 l’origine de ph\u00e9nom\u00e8nes extr\u00eames tant dans l’atmosph\u00e8re que dans les oc\u00e9ans, avec des r\u00e9percussions croissantes sur les populations, les \u00e9conomies et les \u00e9cosyst\u00e8mes \u00e0 l’\u00e9chelle mondiale, a d\u00e9clar\u00e9 Samantha Burgess, responsable strat\u00e9gique pour le climat au Centre europ\u00e9en pour les pr\u00e9visions m\u00e9t\u00e9orologiques \u00e0 moyen terme.<\/p>\n\n\n\n
