There is an 80% chance of the warming El Ni\u00f1o phenomenon developing between June and August, increasing the risk of extreme weather events, the World Meteorological Organization has said.<\/p>\n

“Fuelled by unusually warm ocean waters in the tropical Pacific, El Ni\u00f1o conditions are developing and are set to influence global temperature and rainfall patterns,” the United Nations’ weather and climate agency (WMO) said.<\/p>\n

Forecasts from the WMO global network “indicate a pronounced shift toward El Ni\u00f1o conditions, with probabilities reaching 80% for June-August”, the Geneva-based organisation said.<\/p>\n

El Ni\u00f1o is a natural climate phenomenon that warms surface temperatures in the central and eastern equatorial Pacific Ocean, bringing worldwide changes in winds, pressure and rainfall patterns.<\/p>\n

It typically takes place every two to seven years and lasts around nine to 12 months.<\/p>\n

Conditions oscillate between El Ni\u00f1o and its opposite La Ni\u00f1a, with neutral conditions in between.<\/p>\n

\nEl Ni\u00f1o conditions could affect global temperature and rainfall patterns<\/p>\n

The likelihood of El Ni\u00f1o developing by November is “near or above 90%”, and most forecast models suggest it will be “at least moderate – and possibly strong”, the WMO said in its quarterly El Ni\u00f1o\/La Ni\u00f1a update.<\/p>\n

WMO chief Celeste Saulo said the world therefore needed to get ready for an El Ni\u00f1o which could “exacerbate drought and heavy rainfall and increase the risk of heatwaves both on land and in the ocean”.<\/p>\n

The WMO says that even a moderate El Ni\u00f1o makes some weather and climate extremes more likely.<\/p>\n

The last El Ni\u00f1o contributed to making 2023 the second-hottest year on record and 2024 the all-time high at around 1.55C above the 1850-1900 pre-industrial average.<\/p>\n

‘Urgent climate warning’<\/p>\n

In late April to mid-May, the sea-surface temperature in the central-eastern Equatorial Pacific – the area used as a monitoring reference – was approaching El Ni\u00f1o thresholds, the WMO said, with sub-surface temperatures more than 6C above average.<\/p>\n

Meanwhile, the Southern Oscillation Index – the atmospheric component of El Ni\u00f1o – is also consistent with El Ni\u00f1o conditions developing.<\/p>\n

The WMO said there was no evidence that climate change increases the frequency or intensity of El Ni\u00f1o events.<\/p>\n

\nWMO is warning of above normal temperatures<\/p>\n

However, it can amplify the associated impacts, it says, because a warmer ocean and atmosphere increase the availability of energy and moisture for extreme weather events, such as heatwaves and heavy rainfall.<\/p>\n

“El Ni\u00f1o is arriving on our doorstep,” UN chief Antonio Guterres said in a video message.<\/p>\n

“The world must treat it as the urgent climate warning it is. El Ni\u00f1o conditions will pour fuel on the fire of a warming world. Impacts will hit even harder, travel even farther, and cross borders with devastating speed.<\/p>\n

“The only effective response is climate action equal to the crisis – ending the addiction to fossil fuels, accelerating the shift to renewables, protecting the most vulnerable, and delivering early warning systems for all.”<\/p>\n

Temperatures above normal<\/p>\n

The WMO said that for June to August, forecasts project “a nearly universal dominance of above normal temperatures in nearly all parts of the globe”.<\/p>\n

This increases the risk of compounding hazards in some regions, and accelerating the onset of drought conditions where rainfall is reduced, it said.<\/p>\n

Regional climate centres are predicting “below-normal” rainfall during the critical June-September rainy season in the northern Greater Horn of Africa; below-average monsoon rainfall in south Asia; and drier and warmer summer conditions in central America.<\/p>\n

During the northern hemisphere summer, warm waters associated with El Ni\u00f1o can fuel hurricanes in the central and eastern Pacific, while hindering their development in the Atlantic Ocean.<\/p>\n

The WMO hopes advance warning will guide preparedness, especially in climate-sensitive sectors like agriculture, water management, energy and health.<\/p>\n","protected":false},"excerpt":{"rendered":"There is an 80% chance of the warming El Ni\u00f1o phenomenon developing between June and August, increasing the…\n","protected":false},"author":2,"featured_media":478898,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[246,61,60,82],"class_list":["post-478897","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-environment","tag-ie","tag-ireland","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/478897","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=478897"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/478897\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/478898"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=478897"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=478897"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=478897"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
