GENEVA: The El Nino weather phenomenon, which triggers higher global temperatures, is expected to last until at least April 2024, the United Nations said on Wednesday (Nov 8).
El Nino is a naturally occurring climate pattern typically associated with increased heat worldwide, as well as drought in some parts of the world and heavy rains elsewhere.
The UN’s World Meteorological Organization said the current El Nino, which developed rapidly during July-August this year, was likely to peak between now and January.
“There is a 90-per cent likelihood it will persist throughout the upcoming northern hemisphere winter/southern hemisphere summer,” it said in its latest update, adding that it was expected to last until at least April.
The weather phenomenon typically occurs every two to seven years, and it usually increases global temperatures in the year after it develops.
But, while most of the El Nino impact is not expected to be felt until 2024, WMO highlighted that the phenomenon was occurring in the context of rapid climate change.
Currently the hottest year ever recorded was 2016 – the year after an exceptionally strong El Nino developed – but the world is already on track to beat that record.
“As a result of record high land and sea-surface temperatures since June, the year 2023 is now on track to be the warmest year on record,” WMO chief Petteri Taalas said in the statement, warning that “next year may be even warmer”.
“This is clearly and unequivocally due to the contribution of the increasing concentrations of heat-trapping greenhouse gases from human activities,” he said.
“Extreme events such as heatwaves, drought, wildfires, heavy rain and floods will be enhanced in some regions, with major impacts,” he cautioned, stressing the importance of efficient early warning systems.
