It\u2019s almost a mantra in climate science: The Arctic is warming twice as fast as the rest of the world. But that figure, found in scientific studies<\/a>, advocacy reports<\/a>, the popular press<\/a>, and even the 2021 U.N. climate assessment<\/a>, is incorrect, obscuring the true toll of global warming on the north, a team of climate scientists reports this week. In fact, the researchers say, the Arctic is warming four times faster than the global average.<\/p>\n

\u201cEverybody knows [the Arctic] is a canary when it comes to climate change,\u201d says Peter Jacobs, a climate scientist at NASA\u2019s Goddard Space Flight Center, who presented the work<\/a> on 13 December at a meeting of the American Geophysical Union. \u201cYet we\u2019re misreporting it by a factor of two. Which is just bananas.\u201d<\/p>\n

Researchers have long known the world warms faster in the far north, because of a phenomenon known as Arctic amplification. The drivers of amplification include increased solar heating, as dark ocean water replaces reflective sea ice, along with occasional intrusions of tropical heat<\/a>, carried to the Arctic by \u201catmospheric rivers,\u201d narrow parades of dense clouds that drag water vapor northward.<\/p>\n
