    If you review this article "Large and Rapid Melt-Induced Velocity Changes in the Ablation Zone of the Greenland Ice Sheet" in the July 2008 issue of Science Magazine, I believe you will find that the contentions you report are not supported by the evidence. But, don't let a 17 year study of the Greenland ice sheet get in the way of hyping up a bunch of science fantasy.

    The Inhofe Blog! LOL. That energy company whore? Come on, people. Show me on scientific society that does not completely endorse the fact the the earths atmosphere is warming, and that the burning of fossil fuels is the primary cause of that warming. Show me one National Academy of Science of any major nation that does not endorse that consensus. Show me on major university that does not have a policy statement on global warming that states this. You cannot, because there are not any. The scientific consensus on global warming and it's cause is as solid as that on evolution.

    Now if you are able, accept the challenge and show me a scientific society that states that global warming is not happening, or that the burning of fossil fuels is not the primary cause of the warming.

    This MODIS Terra image, acquired August 23, 2006, shows the southern portion of Greenland. The Greenlandic ice cap covers about 80% of the island's surface. Credit: NASA
    > Click for larger image. A new NASA study confirms 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. So NASA scientists used state-of-the-art NASA satellite technologies to explore the behavior of the ice sheet, revealing a relationship between changes at the surface and below. The new NASA study appears in the January issue of the quarterly Journal of Glaciology.

    Like the AMS position statement that I took you to the cleaners with last week? :eusa_whistle:

    Antarctica Ice Loss Faster Than Ten Years AgoMason Inman
    for National Geographic News

    January 14, 2008
    The western part of Antarctica is shedding ice much faster today than it was just ten years ago, according to new satellite measurements.

    The measurements, which surveyed the coasts of nearly the entire continent, suggest that climate models underestimate how quickly Antarctica responds to ongoing global warming, said study co-author Jonathan Bamber of the University of Bristol in England.

    Global Warming "Tipping Points" Reached, Scientist Says (December 14, 2007)
    Many past studies have tried to estimate how much ice Antarctica is losing.

    (Related: "Hundreds of Glaciers Melting Faster in Antarctica" [June 6, 2007].)

    But the new study is the first to show that this loss is accelerating, at least in western Antarctica and the Antarctic Peninsula, the researchers say.

    "In all the ice sheet models we have at present for Antarctica, things happen very slowly," Bamber said.

    "[But] we're seeing things happen rather quickly."

    They found that for Antarctica overall, the ice loss increased about 75 percent over the ten-year period, from 112 gigatons of ice per year in 1996 to 196 gigatons of ice per year in 2006.

    As to whether Antarctica will lose or gain ice as global warming proceeds, the measurements disagree with existing climate models that suggest "[the ice sheet] is going to get bigger because of increased snowfall with warming temperatures," Bamber said.

    "We don't see that. We see the ice sheet losing mass," he said. "So there's a bit of a paradigm shift in what the ice sheet has done recently and what it could do in the future."

    Scientists are concerned the melting ice will contribute to a dangerous sea level rise.

    Repeat the lie often enough and many fools will begin to believe you. I must admit its a great tactic.

    Indeed, strong observational evidence and results from modeling studies indicate that, at least over the last 50 years, human activities are a major contributor to climate change.

    Direct human impact is through changes in the concentration of certain trace gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor, known collectively as greenhouse gases. Enhanced greenhouse gases have little effect on the incoming energy of the sun, but they act as a blanket to reduce the outgoing infrared radiation emitted by Earth and its atmosphere; the surface and atmosphere therefore warm so as to increase the outgoing energy until the outgoing and incoming flows of energy are equal. Carbon dioxide accounts for about half of the human-induced greenhouse gas contribution to warming since the late 1800s, with increases in the other greenhouse gases accounting for the rest; changes in solar output may have provided an augmentation to warming in the first half of the 20th century.
