Arctic thaw significantly worsens global warming risk
Melting ice is cooking the planet. Shrinking Arctic sea ice means the ocean is absorbing more energy from the sun, and it's now clear the effect is twice as big as thought - adding significantly to heating from greenhouse gases.

From the article:
The extra energy absorbed goes into the ocean, particularly on the side of the Arctic near Alaska and Siberia, which is losing the most ice. "I don't know where it's going from there," says Eisenman.
Lots of AGW energy absorbed by ocean waters that were uncovered by retreating sea ice AND that is over downwellings, is transported to continental shelves & the ocean depths, for ocean depth storage & giving extra energy thawing clathrates.

One thing not mentioned is the shorter season and lower area of snow on land, which also contributes a positive feedback. A stronger one than is commonly understood.
