Although it’s well known that climate change is having dramatic impacts on the North compared to elsewhere in the world, new research suggests that the Arctic is warming significantly more than we thought. In a recent paper published in the journal Geophysical Research Letters, researchers found that the Arctic is heating up to four times faster than the rest of the planet. The Arctic amplification index refers to the ratio between the Arctic and the global mean static air temperature. “Thirty years is considered the minimum to represent climate change,” Petr Chylek, a physicist and climate researcher at Los Alamos National Laboratory and lead author of the study, said in a statement. The researchers examined 39 climate change models in CIMP and found that four of them reproduced the 1986 step, but none reproduced the 1999 step that the researchers detected.
