Africa-Press – Cameroun. <\/strong> <\/span>Ce troisie\u0300me e\u0301pisode mondial de blanchissement, lors de la de\u0301cennie passe\u0301e, a repre\u0301sente\u0301 \u00ab\u00a0de loin le plus grave et le plus e\u0301tendu jamais enregistre\u0301\u00a0\u00bb, souligne Sean Connolly, l’un des auteurs, chercheur a\u0300 l’Institut Smithsonian de recherche tropicale, au Panama.<\/p>\n

Au cours de ces trois anne\u0301es, 51% des coraux ont subi un blanchissement mode\u0301re\u0301 ou plus se\u0301ve\u0300re, occasionnant pour 15% d’entre eux une mortalite\u0301 significative. Les e\u0301pisodes pre\u0301ce\u0301dents (en 1998 et 2010) n’avaient dure\u0301 qu’une anne\u0301e. \u00ab\u00a0Et pourtant, les coraux subissent actuellement un quatrie\u0300me e\u0301pisode encore plus grave, qui a commence\u0301 de\u0301but 2023\u00a0\u00bb, a ajoute\u0301 Sean Connolly dans un communique\u0301.<\/p>\n

\u00ab\u00a0Le niveau de stress thermique a e\u0301te\u0301 extraordinairement e\u0301leve\u0301, notamment en 2023-24, a\u0300 un niveau comparable ou plus e\u0301leve\u0301 encore que ce qui avait e\u0301te\u0301 observe\u0301 en 2014-17, au moins dans certaines re\u0301gions\u00a0\u00bb, a-t-il dit a\u0300 l’AFP.<\/p>\n

Par exemple, la co\u0302te Pacifique du Panama a dernie\u0300rement e\u0301te\u0301 expose\u0301e a\u0300 des effets de la chaleur \u00ab\u00a0bien pire que ce qui avait e\u0301te\u0301 ve\u0301cu auparavant\u00a0\u00bb, avec une \u00ab\u00a0mortalite\u0301 des coraux conside\u0301rable\u00a0\u00bb, ajoute le chercheur.<\/p>\n

\u00ab\u00a0Les conse\u0301quences du re\u0301chauffement de l’oce\u0301an sur les re\u0301cifs coralliens s’acce\u0301le\u0300rent\u00a0\u00bb<\/b><\/p>\n

Les coraux, barrie\u0300res contre l’e\u0301rosion et re\u0301servoirs de biodiversite\u0301, qui stockent e\u0301galement le carbone, blanchissent sous l’effet de la chaleur, ce qui les rend particulie\u0300rement vulne\u0301rables au re\u0301chauffement climatique. Dans des oce\u0301ans plus chauds, ils expulsent les micro-organismes qui leur donnent leurs couleurs vives et leur fournissent leur nourriture, finissant par mourir de faim.<\/p>\n

\u00ab\u00a0Les conse\u0301quences du re\u0301chauffement de l’oce\u0301an sur les re\u0301cifs coralliens s’acce\u0301le\u0300rent, avec la quasi certitude que le re\u0301chauffement actuel occasionnera une de\u0301gradation de ces e\u0301cosyste\u0300mes essentiels a\u0300 grande e\u0301chelle et peut-e\u0302tre irre\u0301versible\u00a0\u00bb, e\u0301crivent les auteurs de l’e\u0301tude.<\/p>\n

Le blanchissement des coraux (AFP\/Archives – Jonathan WALTER, Jean-Michel CORNU)<\/p>\n

La vaste majorite\u0301 des coraux sont condamne\u0301s<\/b><\/p>\n

Les re\u0301cifs ont quasi certainement franchi un point de basculement catastrophique, concluait l’an dernier une e\u0301quipe internationale de quelque 160 scientifiques dans une e\u0301tude de re\u0301fe\u0301rence.<\/p>\n

Les chercheurs estiment qu’avec 1,5\u00b0C de re\u0301chauffement par rapport a\u0300 l’e\u0300re pre\u0301-industrielle, la vaste majorite\u0301 des coraux sont condamne\u0301s. Or, ce seuil sera quasiment certainement franchi dans quelques anne\u0301es, sauf re\u0301duction drastique et imme\u0301diate des e\u0301missions de gaz a\u0300 effet de serre.<\/p>\n

\u00ab\u00a0Nous voyons des re\u0301cifs qui n’ont pas le temps de vraiment se remettre avant le prochain e\u0301ve\u0301nement de blanchissement\u00a0\u00bb, alerte Scott Heron, de l’universite\u0301 australienne James Cook University, l’un des auteurs.<\/p>\n
