Of course we knew all that, but this puts the real numbers on it. Unfortunately like all climate science we cannot compare it properly to previous decades. We do know that the sea ice cover has expanded and this suggests that this reflects the ice gain.
At least NASA has seriously put its foot down on this rather critical issue. Arguing that the Northern Hemisphere is warming while the Southern is cooling is hugely different than claiming the world is warming.
We have been having this exact discussion on this blog for the eight years we have had this blog and until now the skates were on regarding the South. Now they cannot.
NASA reveals that Antarctica is actually gaining more ice than it is losing
Antarctica's ice floes have been found to be growing faster than they are shrinking despite fears over global warming
"Our main disagreement is for East Antarctica and the interior of West Antarctic, there, we see an ice gain that exceeds the losses in the other areas,” added Zwally, an expert at the NASA Goddard Space Flight Center.
The new findings reinforces the challenges in measuring changes in Antarctica.
The surface height of the Antarctic ice sheet was analysed using radar instruments on two European Space Agency satellites between 1992 and 2001.

Laser sensors on a NASA satellite were also used in the research between 2003 to 2008.
Scientists have previously wrongly attributed gains in elevations in East Antarctica to recent snowfall. The NASA team used data dating back to 1979 to prove the ice cores in the area had in fact been thickening.
