Antarctic ice mass shrinking

Two recent reports from NASA-funded scientists agree that, based on satellite data, the water ice locked up in Antarctica is shrinking as the global climate warms, contributing to the rise of sea levels around the world.

But one of the studies found that while glaciers at the edges of Greenland are also melting, the snow pack at the center is growing as snowfall increases - both effects predicted by global warming theory. On balance, then, the water locked up in Greenland's ice and snow gained slightly during the study period, but the net change for both ends of the planet combined, shows a net loss.

The scientists say glacial melt accounts for only a tiny fraction of the rise in sea levels. Most is due to the expansion of the oceans as the waters warm. And even that doesn't explain it all. Where the rest of the added water is coming from remains a scientific mystery.

Here is a news release on the first study, published last week. And here is the release on the second, just out.  Gentle readers, inflate your water wings.
