Norway Swelters: 2025 Hottest Year on Record

Norway endured its hottest year on record in 2025, a trend attributed to a potent summer heatwave and a remarkably mild winter. The Norwegian Meteorological Institute reported that national average temperatures were 1.5°C higher than the 1991-2020 baseline, and a staggering 2.8°C above pre-industrial levels.

The unusual warmth extended to the Arctic, with Longyearbyen in Svalbard reaching 4°C on December 22, a temperature warmer than both Seville and Ankara on the same day. This event underscores the significant impact of climate change.

Experts at the institute anticipate that the extreme temperatures observed in 2025 will become a recurring occurrence in the future, signaling a shifting climate pattern for the region and potentially beyond.
