Where is the water coming from?

Now this is rather odd. A new NASA survey of both Greenland and Antartic ice confirms that, despite increased snow in parts of (I think) both places, overall there is a net loss of ice. One article says:

When the scientists added up the overall gains and loses of ice from the Greenland and Antarctic ice sheets, there was a net loss of ice to the sea. The amount of water added to the oceans (20 billion tons) is equivalent to the total amount of freshwater used in homes, businesses and farming in New York, New Jersey and Virginia each year.

Sounds a lot. But then again, what is happening to sea levels because of this? From the BBC version:

If ice is on balance being lost to the oceans, it could be contributing to global sea-level rise; and according to Jay Zwally's research, it is, but by less than expected.

"The study indicates that the contribution of the ice sheets to sea-level rise during the decade studied was much smaller than expected, just two percent of the recent increase of nearly three millimeters a year," he said.

"Current estimates of the other major sources of sea-level rise - expansion of the ocean by warming temperatures and runoff from low-latitude glaciers - do not make up the difference, so we have a mystery on our hands as to where the water is coming from."

Only 2 % of the current increase is coming from Antartic and Greenland ice? Maybe we have a while before we all drown. Or someone's figures are a bit screwy somewhere.

Also - if you want to see an example of why the media reporting of global warming irritates me, have a look at this recent Newsbusters story, and the "grab" at the bottom of the TV screen shot. It is not outright false, but still it is designed to give the impression of crisis.
