Al Gore says he can see the melt. He must be on some pretty powerful hallucinogens.

Is there data to refute GRACE and the radar study that independently showed decreasing continental ice VOLUME?
Regardless, even if the globe is warming, there is a difference between correlation/association and cause-and-effect. Adjusting the past data to create a trend also doesn’t establish causation, and the component of warming supposedly due to CO2 can be fudged just on the basis of a few incorrect assumptions/constants/feedback magnitudes in the flawed models.

  That’s an interesting question. We can significant ice flows flowing out from the interior of Antarctica which may account for the ice volume loss to some degree, but since the mean annual temperature of the interior is −57°C it strikes me as a little unusual to attempt to explain that movement of ice mass on AGW. I’m not saying I know the answer, but I would like to know how there can be decreasing ice volume at an average temp of −57°C in recent years and expanding sea ice…? I wonder if there has been a decrease in snow fall over Antarctica recently to account for the difference? (Although if that speculation were true, it would be actually the exact opposite of what most climate models have expected.)

  How well does GRACE actually measure Antarctic ice volume? Consider that certain areas of the globe that were once covered by ice age ice sheets are still rising 10k years later. By the same token, just as isostatic rebound is a slow process still ongoing long after the depressing ice sheets have retreated, so the Antarctic continent is continues to sink under the immense weight of the Antarctic ice cap, regardless of whether the ice cap is growing or shrinking. Does one credit that GRACE scientists have an accurate knowledge of the rate of sinking of the underlying bedrock beneath the ice cap.
