August 2026 was jointly the hottest month ever recorded in the world, tying the record of July 2023, according to the European Union's climate service, Copernicus.
The average global temperature during August was about 1.65°C above pre-industrial levels, crossing the critical threshold of 1.5°C, which countries around the world have aimed to avoid to limit the most severe consequences of climate change.
A single month above this level does not mean that the limit has been irreversibly crossed, but it does indicate a worrying trend.
The record has been driven by climate change, but also by the strengthening of the natural phenomenon El Niño, which warms the Pacific waters and releases large amounts of heat into the atmosphere. According to Copernicus experts, the current El Niño is strengthening and could be among the strongest ever recorded, while its greatest impact on global temperatures is expected next year.
August also marked the end of the hottest summer ever recorded in Western Europe. In the United Kingdom, the summer of 2026 was the hottest since records began in 1884. According to experts, climate change caused by human activity has made such a summer much more likely.
The heat wave in Europe caused numerous problems, affecting schools, the health system and agricultural production, while fueling fires and droughts and contributing to tens of thousands of deaths.
Experts warn that record temperatures should not be considered the “new normal.” According to them, as long as fossil fuel burning continues, temperature records will continue to be broken and extreme events will become increasingly severe.
"The evidence is irrefutable," declared UN climate chief Simon Stiell, linking rising temperatures to the use of fossil fuels and the global climate crisis.
