Well this is awkward. Just a month after former Aussie PM Tony Abbott openly questioned global warming data (and was ‘replaced’), a new NASA study finds another inconvenient truth– Antarctica has been adding more ice than it’s been losing, challenging other research, including that of the UN’s Intergovernmental Panel on Climate Change, that concludes that Earth’s southern continent is losing land ice overall.
In a paper published in the Journal of Glaciology on Friday, researchers from NASA’s Goddard Space Flight Center, the University of Maryland in College Park, and the engineering firm Sigma Space Corporation offer a new analysis of satellite data that show a net gain of 112 billion tons of ice a year from 1992 to 2001 in the Antarctic ice sheet.
That gain slowed to 82 billion tons of ice per year between 2003 and 2008.
Climate scientists caution that these findings don’t mean it’s time to start celebrating the end of global warming.
More than anything, the paper shows how difficult it is to measure ice height in Antarctica and that better tools are needed.
For now, the study authors say, these findings challenge current explanations for sea level rise, much of which is attributed to melting ice sheets in Greenland and Antarctica.
“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” said Dr. Zwally.
“But this is also bad news,” he added. “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.”

Perhaps it is time to burn just a little more fossil fuel? And maybe VW was doing a global good with its defeat device?
