Antarctica GAINING 82 to 112 gigatons of Ice per Year

“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.”

“Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year”

The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said.

  1. Antartica ‘gaining mass’ means it is lowering sea level… And that likely means that wells and groundwater extraction now the are the #1 cause of sea rising, followed by ocean thermal expansion and melting glaciers.

    From May 2012:

    “observed sea-level rise between 1961 and 2003. Of that amount, the extraction of groundwater for irrigation and home and industrial use, with subsequent run-off to rivers and eventually to the oceans, represents the bulk of the contribution.”

  2. The GRACE satellite mission says that the Antarctic is loosing mass. If it is actually gaining mass then the GRACE satellite mission is wrong! If the GRACE satellite mission is wrong then it’s measurement of Greenland’s ice mass loss is probably wrong too. Since the GRACE measurement of Greenland’s mass loss is about the same as it’s incorrect measurement of Antarctica’s mass loss then Greenland is probably gaining mass just like Antarctica. If that is true then there can’t be much sea level rise so the sea level rise measurements must be wrong too!
