Antarctic Gains

A study published by NASA last week has created a new stir in the Climate debate.  But, as usual, the stir is mainly fodder for the extreme political poles on either side of sensibility on this issue.  Specifically, a recent NASA analysis of satellite data indicates the southernmost continent is actually experiencing a net gain of ice annually, although that annual gain has slowed in recent years.

Jay Zwally, a glaciologist with NASA, had this to say,  “The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away, but this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”

The study should not be taken as proof that Global Warming is not real.  Rather, it serves to illustrate the complexity of the science and the need for additional study to gain greater understanding.
