Tundra regions warm twice as fast as the global average

Earth's vast, treeless tundra regions are warming at roughly twice the global average rate, a phenomenon called Arctic amplification. Since the late 20th century, diminishing sea ice and snow mean less sunlight is reflected, absorbing more heat. This rapid warming has increased Arctic temperatures by 2-3 degrees Celsius since pre-industrial times, compared to a 1.1-degree global rise.
