Some believe global anomalies are in line with predictions but others are more concerned by speed of change

Heat records are becoming the norm, but the extent of the anomaly in 2024 above the seas has prompted concern.Heat records are becoming the norm, but the extent of the anomaly in 2024 above the seas has prompted concern.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.

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.”Sea surface temperatures in February were also hotter than any month in history, breaking the record set last August, according to Europe’s Copernicus satellite monitoring programme..

Carlos Nobre, one of Brazil’s most influential climatologists, said no climate model accurately predicted how high sea surface temperatures would reach during the past 12 months. Given the continued heat over the sea, he said 2024 was likely to be another unusually hot year for the world as a whole. The anomaly is strongest in the North Atlantic, where Brian McNoldy, a climatologist at the University of Miami, calculated the deviation from statistical averages as a one-in-284,000-year event.
