Climate Characteristics of the 2025/2026 Winter on Earth
The winter of 2025/2026 on Earth has become yet another vivid illustration of ongoing global climate change. Meteorologists and climatologists note that the season was characterized by pronounced heat anomalies in the Northern Hemisphere and an increase in extreme weather phenomena, in line with long-term trends predicted by the Intergovernmental Panel on Climate Change (IPCC).
In the Northern Hemisphere, the winter of 2025/2026 entered the top ten warmest winters on record. The average temperature exceeded the norm by 1.2–1.5°C. This was particularly evident in the Arctic, where temperatures were above the climatic norm by 6–8°C in some periods. The record reduction in sea ice area in the Barents and Kara Seas continued, affecting atmospheric circulation over Eurasia. An interesting fact: in January 2026, a Norwegian research vessel recorded rain at a point located just 800 km from the North Pole – a phenomenon virtually impossible for a typical Arctic winter in the last century.
Europe's winter was marked by instability: relatively mild periods were replaced by sharp, but short-lived intrusions of Arctic air. For example, in February, a powerful sudden stratospheric warming led to the temporary breakdown of the polar vortex. This caused extreme cold and heavy snowfall in Central and Southern Europe, while Scandinavia remained abnormally warm. For instance, Rome experienced a record snowfall in 50 years, while in Helsinki temperatures rarely fell below -5°C.
The Northern America faced a series of powerful atmospheric rivers – narrow streams of very moist air from the tropics. They dumped record amounts of precipitation on the west coast of the United States and Canada, causing floods and landslides. Meanwhile, on the east coast of the continent, especially in New York and Boston, the winter was snowless and mild, with repeated waves of warmth.
In contrast, winter in some regions of Asia was extremely cold. At ...
