PARIS: The EU\u2019s climate monitor said Thursday that August was the hottest single month ever recorded globally, with ocean temperatures also reaching unprecedented highs as western Europe capped its warmest summer.<\/p>\n
In response to the assessment by the Copernicus Climate Change Service, the UN warned that until humanity weaned off fossil fuels, the planet would only push deeper into uncharted territory.<\/p>\n
Copernicus observations go back to 1940 but other evidence – such as ice cores, tree rings and coral skeletons – allow scientists to place today\u2019s climate against a much longer historical context.<\/p>\n
\u201cHumans haven\u2019t seen temperatures as hot as today for, arguably, at least the last 100,000 years,\u201d Samantha Burgess from the European Centre for Medium-Range Weather Forecasts, which oversees Copernicus, told AFP.<\/p>\n
Global average air temperatures in August were 16.96C, Copernicus said – surpassing by 0.01C the previous all-time monthly record set in July 2023. Copernicus said it considered the two months joint-highest given the narrow difference.<\/p>\n
Scientists say that human activity – primarily the burning of coal, oil and gas – has warmed the planet by roughly 1.4C since pre-industrial times and increased the severity and likelihood of extreme weather.<\/p>\n
Yet heat-trapping greenhouse gas emissions rose to new highs in 2025.<\/p>\n
\u201cThe evidence is irrefutable: this is the spiralling price of humanity\u2019s fossil fuel addiction, and the global climate crisis it is fuelling,\u201d United Nations climate chief Simon Stiell said of the Copernicus report.<\/p>\n
More ahead <\/strong><\/p>\n Global sea surface temperatures also set a new daily high and tied equal-hottest for August, extending a three-month streak of record-breaking warmth across the world\u2019s oceans.<\/p>\n More than 90 percent of excess heat trapped by greenhouse gas emissions has been absorbed by the oceans, sparing land from warming but at severe cost to marine life, reefs and coastal communities.<\/p>\n Records tumbled in overheated basins like the Atlantic and Mediterranean and also the tropical Pacific, where the strongest El Nino weather pattern in the modern era is fast accumulating strength.<\/p>\n These events are marked by unusually warm Pacific waters but raise the odds of wild weather thousands of miles away, from floods in Peru to droughts in Africa and wildfires in Australia.<\/p>\n The warmer phase of a natural climate cycle, El Nino episodes usually deliver a temporary spike in global temperatures already elevated by long-term background warming.<\/p>\n Scientists expect records to keep falling in the months ahead as this \u201csuper\u201d El Nino approaches peak intensity around December and for 2027 – and maybe even 2026 – to become the hottest years ever observed.<\/p>\n \u201cClimate change makes every El Nino hotter, and until we stop burning coal, oil, and gas these record-shattering months will simply keep on coming,\u201d said Friederike Otto, a climate scientist from Imperial College London.<\/p>\n Sizzling summer <\/strong><\/p>\n Copernicus also said that August \u201cmarked the end of western Europe\u2019s warmest summer\u201d that surpassed the long-standing record set in 2003.<\/p>\n The June to August season was defined by severe, back-to-back heatwaves that shut schools, dried up rivers and primed the land for devastating wildfires.<\/p>\n Between mid-July and mid-August, the continent\u2019s EuroMomo monitoring platform estimated that Europe saw more than 32,000 excess deaths.<\/p>\n Scientists from the World Weather Attribution network concluded that a particularly strong heatwave in June would have been \u201cvirtually impossible\u201d without the influence of climate change.<\/p>\n But extraordinary heat was felt around the globe.<\/p>\n On Wednesday, the National Oceanic and Atmospheric Administration said the contiguous United States has endured its hottest summer on record.<\/p>\n And regions home to around 900 million people lived through the hottest July ever observed, according to AFP analysis of Copernicus data.<\/p>\n \u201cWe\u2019ve had an exceptional summer — not only in Europe, but other parts of the world where records that have existed for close to a century have fallen,\u201d said Burgess, an ocean scientist and strategic lead for at ECMWF.<\/p>\n The climate would \u201ccontinue to get more extreme unless we turn off the tap to global emissions\u201d, she added.<\/p>\n<\/div>\n
