Global Warming

February 21st, 2008
by Mohit Joshi

A new NASA study has confirmed that the surface temperature of Greenland's massive ice sheet has been rising, stoked by warming air temperatures, and fueling loss of the island's ice at the surface and throughout the mass beneath.

Greenland's enormous ice sheet is home to enough ice to raise sea level by about 23 feet if the entire ice sheet were to melt into surrounding waters.

Though the loss of the whole ice sheet is unlikely, loss from Greenland's ice mass has already contributed in part to 20th century sea level rise of about two millimeters per year, and future melt has the potential to impact people and economies across the globe.

1. All hope abandon, for the end is nigh!

Here is dynamic map for sea level rising

2. IM PRESIDENT BUSH AND I APPROVE THIS MESSAGE

FAMOUS REPUBLICAN RESPONSES TO GLOBAL WARMING:

10 IF YOU CANT TAKE THE HEAT GET OFF OF THE PLANET
9 THIS IS WHY OUR LORD AND SAVIOR TOLD US TO BUILD AN ARK
8 WE DONT BELIEVE IN...BLUB...BLUB...BLUB...
7 I THINK, LIKE IRAQ, THIS IS GOOD FOR THE ECONOMY
6 IS OUR CHILDREN LEARNING
5 HOW TO LEAVE THE NORTH POLE... ROW VS WADE...
4 BROWNIE YOU'RE DOING A HECK OF A JOB... CAN YOU TAKE A LOOK AT THIS GLOBULAR WARNING THING
3 IT'S GOOD FOR ALASKA
2 WHAT WOULD SPONGEBOB DO?
1 AS RONALD REAGAN WOULD SAY "When you can't make them see the light, make them feel the heat"

5. If it's melting, why wouldn't all of it melt? Or most of it?

Isn't that the way to bet?

"...And there ain't no mention of it in the Bible. So I reckon this is just more of that lib-rul science-based fact shit. Smirk. Since I am the Decider, I COMMAND that we keep the oil profits rolling in for my republicon homelander cronies. Smirk. The rest of you can just shut up and sit down. Smirk."

7. is that a picture of Mars on fire?

[paparush]

9. I noticed that too...I know our geography is bad..but, cmon..

11. I'd understand if it was Venus they used.

Allusion and all, but Mars?
Makes NO sense.

10. Greenland experiencing global warming again after 90 years

From the same source, looks like it may have happened before.

Digging through the old data, Herrington found a map from 1932 and an aerial photo from 1933 that documented how, during a warm period, the Kangerdlugssuaq Glacier lost a piece of floating ice that was nearly the size of New York 's Manhattan Island.

"In 2002 to 2003, that same glacier retreated another 3.1 miles (5 kilometres), and that it tripled its speed between 2000 and 2005. "

The fact that recent changes to Greenland's ice sheet mirrors its behavior nearly 70 years ago is increasing researchers' confidence and alarm as to what the future holds.

What was going on 90 years ago to cause this?

12. I'm just speculating here, but maybe it melts by plateaus not a straight line, and 90 years ago

would've been about the time of World War 1, maybe combined with the Industrial Age picking up steam to support the Earth's first World War triggered it? Here's more from your link.

"Recent warming around the frozen island actually lags behind the global average warming pattern by about 1-2 degrees C but if it fell into synch with global temperatures in a few years, the massive ice sheet might pass its "threshold of viability" – a tipping point where the loss of ice couldn't be stopped.

"Once you pass that threshold, " Box said, "the current science suggests that it would become an irreversible process. And we simply don't know how fast that might happen, how fast the ice might disappear. "

Greenland 's ice sheet contains at least 10 percent of the world's freshwater and it has been losing more than 24 cubic miles (100 cubic kilometres) of ice annually for the last five years and 2007 was a record year for glacial melting there."

I suspect China and India's vast modernization and entrance in to the Industrial Age could be triggering it this time. Those are a lot of bicycles being turned in to automobiles, not to mention the factories and industries being created almost overnight.
