Snow over Antarctica Buffered Sea Level Rise during Last Century

A new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.

"Our findings don't mean that Antarctica is growing; it's still losing mass, even with the extra snowfall," said Brooke Medley, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published in Nature Climate Change on 10 December. "What it means, however, is that without these gains, we would have experienced even more sea level rise in the 20th century."
