- The Antarctic ice sheet had net gains in ice of 112 billion tons per year from 1992 to 2001.
- Antarctic ice from 2003 to 2008 had a net gain of 82 billion tons per year.
- Extra snowfall in East Antarctica began about 10,000 years ago as the Earth warmed after the last Ice Age and this snowfall thickened the East Antarctic and the interior regions of the West Antarctic by 1.7 cm/year. This accumulation over vast expanses more than offsets the melting of ice on the West Antarctic peninsula which gets so much publicity.
- The increased ice in Antarctica is now acting to reduce sea levels by 0.23 mm/year.
The findings of this study were the result of more accurate measurements of the small thickening of the ice in most of Antarctica from satellite measurements, with the exception of the ice core investigations by others that indicated the increase in snowfall beginning 10,000 years ago. It would not be surprising if the application of these satellite analysis methods to Greenland were to find that previous claims of large ice losses there were also wrong. It is easy to observe large glaciers calving into the ocean while missing the slow increases of ice thickness over much larger areas.
