NASA - Ice Satellite Shows Thinning At All Latitudes Of Greenland, Far Inland On Antarctic Sheets
Researchers have used NASA's Ice, Cloud and Land Elevation Satellite (ICESat) to compose the most comprehensive picture of changing glaciers along the coast of the Greenland and Antarctic ice sheets.

The new elevation maps show that all latitudes of the Greenland ice sheet are affected by dynamic thinning - the loss of ice due to accelerated ice flow to the ocean.

The maps also show surprising, extensive thinning in Antarctica, affecting the ice sheet far inland. The study, led by Hamish Pritchard of the British Antarctic Survey in Cambridge, England, was published September 24 in Nature.

ICESat's precise laser altimetry instrument, launched in 2003, has provided a high-density web of elevation measurements repeated year after year across the Greenland and Antarctic ice sheets. With the dense coverage, the research team could distinguish which changes were caused by fast-flowing ice and which had other causes, such as melt. The maps confirm that the profound ice sheet thinning of recent years stems from fast-flowing glaciers that empty into the sea.

2. Where are the deniers these days?
Back under their rocks?

At it again: George Will claims evidence of warming is "elusive"

October 01, 2009 3:39 pm ET

In his Washington Post column, George Will claimed that "evidence" of climate change is "elusive" and that scientists are overstating the threat of warming when they say -- in the words of a September 21 New York Times article Will criticizes -- that a recent "plateau" in temperatures has "no bearing" on the long-term warming trend; in fact, scientists routinely present strong evidence of long-term warming and its consequences -- including a September 2009 United Nations report Will himself cited that says "rapid environmental change is underway with the pace and the scale of climate change accelerating." Will has previously been criticized by the World Meteorological Organization, his own Post colleagues, and others for misusing scientific data to claim that warming may not be occurring.

Hannity, oblivious to "scientific nuances," takes NY Times out of context on global warming

September 25, 2009 7:33 pm ET

On his September 23 show, Sean Hannity claimed that a New York Times article reporting that "global temperatures have been relatively stable for a decade and may even drop in the next few years" is in conflict with President Obama's comments at the United Nations that "(i)f we continue down our current course, every member of this assembly will see irreversible changes within their borders." But Times reporter Andrew C. Revkin, in the article Hannity misconstrued, also reported that the recent temperatures have "been seized upon by skeptics" but that scientists say short-term climate variability "has no bearing on the long-term warming effects of greenhouse gases" and that "trying to communicate such scientific nuances to the public -- and to policy makers -- can be frustrating."

Beck, Hannity falsely claim IPCC's Latif has "pulled the rug out" from under climate change consensus

September 24, 2009 3:47 pm ET

On their radio shows, both Glenn Beck and Sean Hannity seized on a World Climate Conference presentation on short-term natural climate variability by Mojib Latif, a prominent climate modeler, to suggest that, in Beck's words, Latif has "backed out now and said, 'We were wrong,' " about global warming because, according to Hannity, Latif stated that global temperatures are actually "cooling." In fact, Latif asserted that contrary to common "media" misperceptions of global warming as a "monotonic process" in which "each year is warmer than the preceding year," there are significant natural climate variations within the decadal timescale that do not change the "long-term warming trend."

4. Heh, I'd love to see a full blown denier here on E/E. There are a few minor skeptics...
...but they at least have an open mind and can appreciate the arguments (though they can get heated at times). Most real full blown deniers who refuse to accept real evidence hang out at ClimateAudit and other right wing websites.
