Latest data shared by the World Meteorological Organization (WMO<\/a>) indicates a 55 per cent likelihood that sea surface temperatures in the equatorial Pacific will cool to La Ni\u00f1a levels from September to November.<\/p>\n

About 90 per cent of the\u00a0excess\u00a0heat\u00a0from global warming\u00a0is stored in\u00a0the\u00a0ocean, making ocean heat content a critical indicator of climate change.\u00a0<\/p>\n

\u201cFor October to December 2025, the probability of La Ni\u00f1a conditions slightly increases to about 60 per cent. There is little chance of El Ni\u00f1o developing during September to December,\u201d WMO said in an update.<\/p>\n

According to the UN agency, there is a smaller chance (45 per cent) that Pacific temperatures will stay as they have for the past six months, when neither the cooling La Ni\u00f1a nor its opposite number, the warming El Ni\u00f1o, caused unusual spikes or dips in sea surface temperatures.<\/p>\n

Lifesaving insight<\/p>\n

The UN agency\u2019s forecast for the El Ni\u00f1o Southern Oscillation phenomenon is an important climate intelligence tool which could \u201csave thousands of lives when used to guide preparedness and response actions\u201d, insisted WMO Secretary-General, Celeste Saulo.<\/p>\n

The information could also translate into millions of dollars of savings in agriculture, energy, health and transport, she said.<\/p>\n

Important as La Ni\u00f1a and El Ni\u00f1o are in shaping our climate by altering ocean surface temperatures and impacting changes in winds, pressure and rainfall patterns, human-induced climate change is still \u201cincreasing global temperatures, exacerbating extreme weather, and impacting seasonal rainfall and temperature patterns\u201d, WMO noted.<\/p>\n

Each year of the past decade has been the top 10 warmest on record, the UN agency warned earlier this year<\/a>, with 2024 the hottest yet, with \u201cexceptional land and sea surface temperatures and ocean heat\u201d.<\/p>\n

Citing six international datasets, WMO said that global average surface temperature was 1.55\u00b0C\u202f(34.79\u00b0F) above the 1850-1900 average.<\/p>\n

\u201cBlazing temperatures in 2024 require trail-blazing climate action in 2025,\u201d said UN Secretary-General Ant\u00f3nio Guterres<\/a> at the time. \u201cThere’s still time to avoid the worst of climate catastrophe. But leaders must act \u2013 now,\u201d he insisted.<\/p>\n

Other key climate phenomena that influence global temperature include the North Atlantic Oscillation, the Arctic Oscillation and the Indian Ocean Dipole. Their impact on surface temperatures and rainfall are monitored by WMO and published in regular\u00a0Global Seasonal Climate Updates (GSCU).<\/a><\/p>\n

The latest Update<\/a>\u00a0indicates that for September to November, temperatures are expected to be above normal in much of the Northern hemisphere and large parts of the southern hemisphere.<\/p>\n

Rainfall predictions are expected to be similar to those typically observed during a moderate La Ni\u00f1a, the WMO assessment noted.<\/p>\n","protected":false},"excerpt":{"rendered":"Latest data shared by the World Meteorological Organization (WMO) indicates a 55 per cent likelihood that sea surface…\n","protected":false},"author":2,"featured_media":119321,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[64,63,75,128],"class_list":["post-119320","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-au","tag-australia","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/119320","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=119320"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/119320\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/119321"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=119320"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=119320"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=119320"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
