A new NASA study found that 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.
