'The new study, published in the Journal of Glaciology,
doesn't totally undermine the handful of studies showing significant
glacier, ice sheet and sea ice shrinkage. Instead, if offers evidence of

'The new tallies reveal an annual net gain of 112 billion tons between
1992 and 2001. Annual gains of 82 billion tons were observed between

'"We're essentially in agreement with other studies that show an
increase in ice discharge in the Antarctic Peninsula and the Thwaites
and Pine Island region of West Antarctica," lead study author Jay
Zwally, a glaciologist with NASA Goddard Space Flight Center, said in a press release.
"Our main disagreement is for East Antarctica and the interior of West
Antarctica -- there, we see an ice gain that exceeds the losses in the

reveal "small height changes over large areas, as well as the large
changes observed over smaller areas."'
