WASHINGTON More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming.
More than half of the loss of landlocked ice in the past five years has occurred in Greenland, based on measurements of ice weight by NASA's GRACE satellite, said NASA geophysicist Scott Luthcke. The water melting from Greenland in the past five years would fill up about 11 Chesapeake Bays, he said, and the Greenland melt seems to be accelerating.
NASA scientists planned to present their findings Thursday at the American Geophysical Union conference in San Francisco. Luthcke said Greenland figures for the summer of 2008 aren't complete yet, but this year's ice loss, while still significant, won't be as severe as 2007.
The news was better for Alaska. After a precipitous drop in 2005, land ice increased slightly in 2008 because of large winter snowfalls, Luthcke said. Since 2003, when the NASA satellite started taking measurements, Alaska has lost 400 billion tons of land ice.
In assessing climate change, scientists generally look at several years to determine the overall trend.
Melting of land ice, unlike sea ice, increases sea levels very slightly. In the 1990s, Greenland didn't add to world sea level rise; now that island is adding about half a millimeter of sea level rise a year, NASA ice scientist Jay Zwally said in a telephone interview from the conference.

Other research, being presented this week at the geophysical meeting point to more melting concerns from global warming, especially with sea ice.
"It's not getting better; it's continuing to show strong signs of warming and amplification," Zwally said. "There's no reversal taking place."

As a data point, the "2 trillion tons of ice melt" they are talking about represents about 0.0074% of the "land ice" in the world. They are also not mentioning ice _accumulation_ that's happened in some regions, for instance parts of Antarctica.
Also, take a look at the animation at the bottom of this page:

Most of the summer's anomalies have been wiped out - and remember the anomalies are against historical averages. Also, we're not even quite to winter yet, and it looks to be a very cold one...
We're about to the end of 2008, with sunspot activity still at a definite minimum - looks to be more cold times ahead.
(Just put it on our tab.)
It's all in New Hampshire, now.
0.0074%!!!! oh geeze run for the hills people!!!
Do you think these blatant misrepresentations are largely because of the media and maybe one or two “scientists” who play ball and give them idiotic quotes to print? I hate to think NASA scientists are in on it too.
obama’s fault......
I didnt realize how important global warming was till I saw the new “the day the earth stood still”. We better shape up, who knows when the aliens are going to come and eliminate us cause we’re destroying our planet? And Im sure when they do come they will go right after the movies stars for creating such a travesty on the silver screen.
It was named GREENLAND for a reason...
“NASA ice scientist Jay Zwally said in a telephone interview from the conference”
blah..nevermind they’re in on it
The Little Ice Age in the 1400’s, I believe was brought on by Greenland ice melt. Lasted into the mid-1700s. Could be wrong.
I never knew that Polar Bears lived on a diet of ice. I thought they drank Coca Cola. What did Polar Bears do to survive before the Polar Ice caps formed during the Ice Age?
And yet Greenland still isn't as warm and green as it was around 900 to 1300.
And if they didn’t tell us, we would never know it. That’s some crisis.
I like this site:

And where did the ice come from to begin with?
One of the worst prevaricators, James Hansen works for NASA and he’s one of the biggest global warming propagandists in existence. He deliberately fudges NASA’s weather data to create global warming scare scenarios that have no existence in reality. The lying incompetent Hansen should be fired by NASA.
All I want to know is how much has the ocean levels risen in the past 20 year as proof?
Our friends seawall down in Florida is the same distance off the water at high tide since it was put in, and that was back in the 50’s.
Notice the headline reads: 2 trillion tons of ice melted..
We are talking about it
Had it read: 0.0074% of ice melted...
No one would even bother to read it.
Global warming is a socialist plot to surren der control of the government to environmentalist WHACKOS. Don’t buy into it.
