Missing factors in climate models suggest Antarctic melt may not be so bad after all

Watts Up With That?

Geophysics could slow Antarctic ice retreat
Gravitational effects, variations in Earth structure could damp rise in global sea levels

The anticipated melting of the massive West Antarctic Ice Sheet could be slowed by two big factors that are largely overlooked in current computer models, according to a new study.

The findings, published online in Nature Communications, suggest that the impact on global sea levels from the retreating ice sheet could be less drastic – or at least more gradual — than recent computer simulations have indicated.

Over the past year, numerous studies have warned that parts of the West Antarctic Ice Sheet are on the verge of a runaway retreat. Just last week a high-profile research paper forecast that this could lead eventually to a rise in global sea levels of as much as three metres.

The authors of the new Nature Communications paper, however, focus on…
