INTRO: Record temperatures in 2024 on land and at sea have prompted scientists to question whether these anomalies are in line with predicted global heating patterns or if they represent a concerning acceleration of climate breakdown.
Heat above the oceans remains persistently, freakishly high, despite a weakening of El Niño, which has been one of the major drivers of record global temperatures over the past year.
Scientists are divided about the extraordinary temperatures of marine air. Some stress that current trends are within climate model projections of how the world will warm as a result of human burning of fossil fuels and forests. Others are perplexed and worried by the speed of change because the seas are the Earth’s great heat moderator and absorb more than 90% of anthropogenic warming.

Earlier this month, the World Meteorological Organization announced that El Niño, a naturally occurring climate pattern associated with the warming of the Pacific Ocean, had peaked and there was an 80% chance of it fading completely between April and June, although its knock-on effects would continue.
The WMO secretary general, Celeste Saulo, said El Niño contributed to making 2023 easily the warmest year on record, although the main culprit was emissions from fossil fuels.
When it came to oceans, she said, the picture was murkier and more disturbing: “The January 2024 sea surface temperature was by far the highest on record for January. This is worrying and can not be explained by El Niño alone.” (MORE - details)
