...""The paper's finding that climate models tend to underestimate the warming ratio [between the Arctic and the Earth as a whole] is really interesting," says Kyle Armour, a climate scientist at the University of Washington who was not involved in the new study.
Previous studies have found that computer models actually do a good job estimating how much the Arctic has heated up, but that they tend to overestimate how much hotter the whole planet is, Armour explains. That means the models' comparison between Arctic warming and overall warming ends up being incorrect.
"We have more work to do to figure out the source of this model bias," says Armour. And that work is increasingly important, because world leaders use climate models to understand what the future holds and how to avoid even more catastrophic warming."
