Sea level could rise faster while Antarctic gains mass

Hot off the press are some interesting findings.

In brief:
If iceberg calving in the Antartic (huge chunks braking off the ice shelves) continue at current rate, glaciers could get involved. It appears that, if unencumbered, they slip faster into sea, then previously thought. This could far accelerate sea level rise beyond the currently projected 28-43 cm over the next 100 years.
However, overall, the Antarctic is not likely to loose ice mass. Instead it will gain from more intense precipitation in the form of snow fall. Also, widespread thawing of the Antarctic is not likely due to the extreme cold.
This current finding seems to support the idea that the Atlantic sea mass and currents are at greater risk of widespred change then the Pacific. For that reason too, when it comes to regulating oceanic changes, Earth agmentation should start at the Gulf. Check out this article on the subject.

This is a really interesting post. When most people hear something like the Antartic is increasing in mass, they think "well, there you go. There is no global warming." Your post and the accomapnying post give a great explanation and perspective on this issue.
