Greenland ice sheet slams the brakes on (global warming)

Much noise has been made about how water lubricates the base of Greenland's ice sheet, accelerating its slide into the oceans. In a rare "good news" announcement, climatologists now say the ice may not be in such a hurry to throw itself into the water after all. Mother Nature, it seems, has given it brakes.

Since 1991, the western edge of Greenland's ice sheet has actually slowed its ocean-bound progress by 10%, say the team, who have studied the longest available record of ice and water flow in the region.

Not all scientists agree. Jay Zwally of NASA's Goddard Space Flight Center in Greenbelt, Maryland, US, says that averaging data over the last 17 years does not make sense because the most rapid melting at the edges of the ice sheet did not start until recently.

"It's only in the last five years or so that the warming signal has really been visible," he says.

Zwally told New Scientist that unpublished data from the eastern edge of the ice sheet suggests between 3% and 5% more ice is being lost because of lubrication than would otherwise happen. That is less than the 25% that was previously calculated, but still significant, he says.

Thank God!

This means that polar bears will not be floating over to Iceland...because they get shot and killed over there.

Global warming con artists are proved wrong once again. Their climate data was proved to be false. 1998 was not the warmest year on record as global warming people said. 1934 was. This junk science and political dishonesty to promote government taking more money from the American people has been proved wrong over and over. But the Democrats and the MSM keep pushing it and many people are dumb enough to believe it.

There is so much that the so-called “experts” do not understand about the climate, the earth, and the solar system. How they can claim that “global climate warming (and cooling) change” is irrefutably caused by man is simply absurd.

Did you notice the color of this bear? An investigation is in order.

The explanation of the bear in Iceland doesn't make any sense. Since Polar bears are at the high point of population numbers, it would make much more sense that they are expanding to greater areas, just like the black bears and grizzlies in the USA and Canada.

We The People pay NASA to do Space (which they do a great job of). Why is our tax money being used for their lies about climate change?

Yes, folks. This polar bear was hit by a speeding, sliding ice sheet. An ice sheet sent rocketing by GLOBAL WARMING. SAVE THE POLAR BEARS! STOP SPEEDING ICE SHEETS!

STOP SPEEDING ICE SHEETS!

Well, lets not get carried away here, and become rash.

In a more pragmatic first step, lets just place a 55 MPH limit on the ice sheets. Once we gain on this slippery slope, get the converts, THEN stop the sheets outright.

“Once we gain on this slippery slope”

Sliding ice sheets, slippery slope...

You made a funny!
