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."

Thanks for the link. The earthquake this AM in Sweden indicates additional Artic instability too.
The ice is melting...we must be doing something to cause it. Because everything has to do with us. /s
Defying Predictions, Sea Level Rise Begins to Slow
World’s oceans rise slower since 2005, fail to display predicted accelerating trend.

About 7.57 by my calcs, but damn close enough for this kind of silliness.
Thanks for the back up!
Someone is missing a great opportunity to bottle that water and sell it to drought stricken areas of the globe.
And where did the ice come from to begin with?
The New Ice Age that Reaganomics caused. Our only hope to stop the melt? Taxes on the wealthy. Don't question me on details boy, it's SCIENCE!
Gore looks like he’s using the rifle as a bong.
LMAO...that pic says it all don’t it. What a maroon
OF course, what none of these ninny-hammers tell you - that a bajillion tons of ice melt EVERY year in the Arctic - regardless of the climate. They completely ignore the INCREASING ice on the polar caps that is evident in the satellite imagery.
:-) Priceless.
It didn’t “melt”, it simply migrated south to the US lower 48. And so what if it did melt - it hasn’t always been there.
I ran the numbers, and had a junior co-worker check my numbers. LOL! Work is really busy now, can you tell?
Heard this piece of propagada on radio this morning.
The sheer volume, or weight, or frequency, or adventurousness of the scams and schemes has reached critical mass in 2008. When it blows up the planet will disappear and space aliens will have to find a new vacation destination.
“What a maroon”
Well, there’s no mag in the rifle, so he’s ‘safe’... lol
They know that Americans educated in the public schools don’t know or understand the metric system so a millimeter may as well be a mile.
2 trillion tons? Wow! Just think how many ounces that would be!
“More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003”
No matter what % of total land-ice that figure represents, consider what happens in all cycles - the peak (or trough) is at the highest (lowest) extreme when??? - Just as the cycle is beginning to turn in the other direction.
The recent-decades highs are in the peak-arena of a natural “warming” trend; the reversal of which is already showing its signs.
