EU monitor says global temperatures were 1.75C above preindustrial levels, extending run of unprecedented highs
A run of record-breaking global temperatures has continued, even with a La Niña weather pattern cooling the tropical Pacific. The Copernicus Climate Change Service said last month was the warmest January on record, with surface – air temperatures 1.75C above preindustrial levels. The EU-funded Earth observation programme highlighted wetter-than-average conditions in eastern Australia and drier-than-average conditions in other parts of the country. Samantha Burgess, the strategic lead for climate at the European Centre for Medium-Range Weather Forecasts, said: “January 2025 is another surprising month, continuing the record temperatures observed throughout the last two years … Copernicus will continue to closely monitor ocean temperatures and their influence on our evolving climate throughout 2025.” Sea-surface temperatures remained unusually high in many ocean basins and seas. January marked the 18th month of the past 19 to record global-average surface temperatures above the 1.5C preindustrial level. Under the Paris climate agreement, world leaders said they would try to prevent global temperatures rising by more than 1.5C – but the threshold was based on long-term multidecadal warming and not short-term monthly temperatures. Climate scientists had expected this exceptional spell to subside after a warming El Niño event peaked in January 2024 and conditions shifted to an opposing, cooling La Niña phase. But the heat has lingered at record or near-record levels, prompting debate about what other factors could be driving it to the top end of expectations. Julien Nicolas, a climate scientist at Copernicus, told Agence France-Presse: “This is what makes it a bit of a surprise: you’re not seeing this cooling effect, or temporary brake at least, on the global temperature that we were expecting to see.”

Apparently, man-made global warming has swamped the natural cooling of La Niña, and I suspect that much of the heating that was attributed to the last El Niño was, in fact, man-made.
