Arctic air temperatures are still increasing at twice the rate of global air temperatures, a NOAA-led report has found.

This year’s Arctic Report Card, a collaborative report by 63 authors from 13 countries, reports a disappointing continuation of Arctic warming: Alaska is seeing temperature anomalies more than 18 degrees Fahrenheit higher than the January average; temperatures are rising in the seas of the Arctic Ocean; and snow cover across the Arctic region is below average.

The report also includes an assessment of climate change’s impact on polar bears, finding a population decline in Hudson Bay, Canada, where the ice season is turning shorter. Still, polar bear numbers have stabilized elsewhere, including in the southern Beaufort Sea.
