August 2026 Ties Global Heat Record

August 2026 was tied with July 2023 as the hottest month globally since modern records began, according to the European Union’s Copernicus Climate Change Service. The global average air temperature reached 16.96°C, or 1.65°C above the pre-industrial reference period of 1850–1900. It was the first month since November 2025 to exceed 1.5°C above pre-industrial levels, the threshold highlighted in the Paris Agreement, although a single month above that level does not constitute a breach of the agreement’s long-term warming goal. Global extra-polar oceans also recorded their warmest August ever, with an average surface temperature of 21.07°C. Samantha Burgess of the European Centre for Medium-Range Weather Forecasts said the figures demonstrated how climate change was intensifying extremes in both the atmosphere and oceans, with consequences for communities, economies and ecosystems. Western Europe experienced its hottest summer on record, surpassing the previous record set in 2003. Heatwaves began unusually early, in some areas as soon as May, and remained prolonged and intense. European land temperatures averaged 20.26°C in August, making it the continent’s fourth-warmest August on record. The heat was accompanied by widespread drought, exceptionally low water levels in major rivers including the Rhine, Danube, Vistula, Rhône and Po, and numerous wildfires. Simon Stiell, the UN Climate Change Executive Secretary, attributed the escalating records and extreme heat to fossil-fuel pollution and called for a faster transition to clean energy. The report presents the data as further evidence that global warming is driving increasingly severe and widespread climate extremes.

The European Union’s Copernicus climate service reported that August 2026 was the hottest month ever recorded globally. The planet’s average temperature reached 16.96°C, narrowly exceeding the previous monthly record set in July 2023 by 0.01°C. August was also 1.65°C warmer than pre-industrial levels, surpassing the 1.5°C threshold established in the 2015 Paris climate agreement. The Northern Hemisphere experienced its hottest recorded summer, while western Europe recorded its warmest summer in the Copernicus dataset. Copernicus said the eight hottest months on record have occurred since July 2023. Global ocean temperatures in August matched the record set in March 2024, and August 22 was identified as the hottest day ever recorded for the world’s seas. The article attributes the exceptional heat to the combined effects of long-term, human-caused climate change and a strengthening El Niño weather pattern. Scientists quoted in the report emphasized that fossil-fuel emissions remain the dominant cause. El Niño typically adds only 0.1°C to 0.2°C to global temperatures, while the overwhelming share of the warming comes from burning coal, oil and natural gas. The current El Niño is expected to become unusually strong in the coming months. Researchers warned that continuing temperature increases will make heat waves, storms, floods and wildfires more frequent and dangerous. They also stressed that the current conditions are consistent with climate projections made decades ago, rather than being unexpected events. Samantha Burgess of Copernicus said climate change is increasingly disrupting daily life through school closures, overwhelmed hospitals, damaged roads and buckled railway lines. Copernicus records extend to 1940, while longer-running U.S. and global datasets begin in 1895 and 1880, respectively.

The European Union’s Copernicus Climate Change Service reported that August was the hottest single month ever recorded globally, based on its observational data dating back to 1940. Global average air temperatures reached 16.96 degrees Celsius, narrowly exceeding the previous monthly record set in July 2023 by 0.01 degrees. Because the difference is so small, Copernicus characterized August and July 2023 as effectively joint record holders. The record heat extended beyond land temperatures. Ocean temperatures also reached unprecedented levels, while western Europe experienced its warmest summer on record. Samantha Burgess of the European Centre for Medium-Range Weather Forecasts, which oversees Copernicus, said current temperatures were likely hotter than anything humans had experienced for at least 100,000 years. Scientists can compare modern observations with this much longer climate history using evidence from ice cores, tree rings and coral skeletons. The report prompted a warning from the United Nations that continued reliance on fossil fuels would push the planet further into “uncharted territory.” Scientists attribute approximately 1.4 degrees Celsius of warming since pre-industrial times primarily to human activities, especially the burning of coal, oil and gas. That warming has increased both the likelihood and severity of extreme weather events. Overall, the article presents August’s temperature record as part of a broader pattern of rapidly intensifying climate change. It combines measurements from climate-monitoring agencies with longer-term paleoclimate evidence and emphasizes that the continued use of fossil fuels is driving dangerous and historically unusual conditions.

August tied with July 2023 as the hottest month in recorded history, according to the European Union’s Copernicus Climate Change Service. The global average surface air temperature reached 16.96°C, or 1.65°C above the estimated 19th-century pre-industrial average. It was the first month since November 2025 in which global temperatures exceeded 1.5°C above pre-industrial levels. The record heat coincided with widespread climate-related disasters. Wildfires affected areas from Indonesia to Greece and Belgium, while Hungary and Romania experienced severe drought. Landslides and flash floods in Nepal and China’s Tibet killed hundreds, and scientists said climate change likely contributed, although the precise links remain under study. Western Europe also experienced its hottest summer on record, with low river flows and depleted soil moisture worsening the effects of repeated heatwaves on agriculture. Scientists stressed that a single month above 1.5°C does not mean the Paris Agreement target has been formally breached, because the agreement refers to a long-term, decades-long average. Global long-term warming is currently estimated at about 1.4°C. However, the United Nations recently warned that limiting warming to 1.5°C over the long term is no longer achievable and called for faster cuts in carbon dioxide emissions to minimize the amount and duration of any overshoot. August also brought record or joint-record ocean temperatures outside the polar regions. Rising temperatures in the tropical Pacific, associated with a strengthening El Niño pattern, could push global temperatures even higher in the coming months. The findings underline both the accelerating effects of climate change and society’s limited preparation for extreme heat and related disruptions.
