The meltdown at the top of the world proceeded at an unprecedented clip over the past year, a sweeping scientific report said Tuesday.

The annual Arctic Report Card, presented by the National Oceanic and Atmospheric Administration at the American Geophysical Union conference in San Francisco, documented rapid changes in the region in 2016, including several records.

Air and sea-surface temperatures are higher, sea ice is sparser and more fragile and ocean waters are absorbing more carbon, changing their chemistry to more acidic levels, while warming tundra is now expelling more carbon that it is drawing in from the atmosphere.
