Greenland Melting? Not so Fast, It’s Gaining Mass. So is Antarctica.

Greenland Ice Study

The treat of rising sea levels is link to land supported ice only, since floating fresh water ice has already displaced the sea water it floats on.

All of Greenland ice has the capacity to raise ocean levels 8 feet. But in reality the ice mass is at record level.  You have been lead to believe differently.  Here is the daily and seasonal change in Surface Mass Budget giga-tons (Billion Metric Tons)

The ice sheet is melting only along the westerly and northerly margin.






NASA Study: Mass Gains of Antarctic Ice

Sheet Greater than Losses

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed   to 82 billion tons of ice per year between 2003 and 2008.

Sums are for all of Antarctica:
East Antarctica (EA, 2-17); interior West Antarctica (WA2, 1, 18, 19, and 23); coastal West Antarctica (WA1, 20-21); and the Antarctic Peninsula (24-27).
A gigaton (Gt) corresponds to a billion metric tons, or 1.1 billion U.S. tons.
