October 2026 was the hottest October worldwide since records began. The average air temperature at the surface was 1.75 degrees Celsius higher than in the pre-industrial period, according to the European Union's climate service Copernicus. Spiegel.de ↗
The year 2026 will very likely be the second-hottest year in recorded history. A higher average temperature has so far only been recorded in the record year 2024. Thus, in 2026 too, the average global temperature will likely exceed the threshold of 1.5 degrees Celsius above the pre-industrial period. Le Monde ↗
The climate service also stated that this will only be the second time the annual average temperature has exceeded this threshold. The first time was in 2024. October also brought historically the highest ocean temperatures. Der Standard ↗
According to the published data, the development is also being influenced by the exceptionally strong El Niño climate phenomenon, which intensifies global warming caused by human activity. The assessment is based on measurements of global temperatures and a comparison with the period before the extensive use of fossil fuels. RTE News ↗
Forecasts also suggest that 2027 could bring warming of approximately 1.8 degrees Celsius compared to the pre-industrial era. The development will depend on the further course of climate phenomena and the continuation of the trend of rising global temperatures.
