The Arctic is the world’s region that has warmed the most, followed by Europe

The world is heating up. By the 2010s, the global average temperature of the air above the surface was about 1°C higher than in the 1940s. But some regions are warming much faster.

The chart shows how average surface air temperatures have changed each decade across continents and oceans compared to historical averages.

The Arctic warmed more than any other region — by the 2010s, it was 2.8°C hotter than in the 1940s.

In the Arctic, melting sea ice has amplified this temperature increase: ice reflects sunlight, so having less of it leads to more warming.

Europe was in second. Since land heats up faster than water, its mostly land-based geography has increased its rate of warming. It has also seen a rapid reduction in aerosols from air pollution. These improvements in air quality can inadvertently increase temperatures because there are fewer aerosols to reflect sunlight.
