Neat study, thanks. I don't understand what is inconvenient about it though. It may or may not be correct (I'm sure others will try and duplicate the findings) but it doesn't seem to do anything to dispute a grand notion of anthropogenic climate change. It says that the Greenland and Antarctic glaciers are not melting as fast as some recent studies have shown. That would be a very good thing because, as this article notes, the IPCC report uses estimates of glacier melting that are *lower* than what the recent studies have shown. So if this new study is correct, then glacier melting rates in Antarctica and Greenland (it does not seem to address other glacial areas) would probably be closer to what was presumed in the IPCC report than what many had feared they actually are. One thing that I thought was interesting about the article was their wording on sea level change. It said: "If the figures for overall sea level rise are accurate, icesheet loss would be contribute about 30 percent, rather than roughly half, to the total, said Vermeersen. The rest would come mainly from thermal expansion, meaning that as the sea warms it rises." So the authors of the study haven't even concluded that their revised estimates of glacial melt will change predictions on sea rise. I suppose that that kind of makes sense. The faster that the Greenland ice cap melts, the more cold water gets pumped into the ocean, keeping its temperature down. If the melt happens more slowly then the temperature could rise more quickly thereby causing additional sea level rise due to thermal expansion. Makes sense but I hadn't really thought about the tradeoff between input of additional fluid water versus rise due to water temperature change. Interesting, thanks.
