Model output for "Observed Antarctic sea ice expansion reproduced in a climate model after correcting biases in sea ice drift velocity"
The Antarctic sea ice area expanded significantly during 1979-2015. This is at odds with state-of-the-art climate models, which typically simulate a receding Antarctic sea ice cover in response to increasing greenhouse forcing. Here we investigate the hypothesis that this discrepancy between models...
