The World Meteorological Organization (WMO), has forecasted that there’s a likelihood of La Niña conditions resurfacing later this year.
The 2023/24 El Niño event, which contributed to global temperature spikes and extreme weather, was showing signs of winding down.
WMO’s latest forecast indicates a 50% chance of either neutral conditions or a transition to La Niña during June–August 2024. As we move into July–September, the probability of La Niña increases to 60%, and by August–November, it reaches 70%. During this period, the chance of El Niño redeveloping is negligible.
El Niño event, a cyclical warming of the Pacific Ocean, has captured global attention. As the World Meteorological Organization (WMO) releases its latest forecast, what is the implications for our planet’s ecosystems and the habitats we call home?
Historically, El Niño, characterized by elevated sea surface temperatures in the equatorial Pacific, has a history of disrupting weather patterns worldwide. Its impacts extend beyond meteorology, affecting marine life, agriculture, and human settlements.
The last strong El Niño, in 2015, coincided with a massive marine heatwave known as “The Blob.” This dual impact weakened ecosystems, harmed species, and left a lasting imprint on our environment.
