After reading the AP version of this story about water channels found in Antarctic ice, one would get the impression that Global Warming melted all this ice, and this water could be the source of the coming sea level rise. Look at this sentence: "It's a finding that may improve understanding of the interaction between global warming and the melting of Antarctic ice, which could contribute to a worldwide rise in ocean level." From my understanding of pressure and low temperatures from statistical mechanics, I immediately knew that I was being given a very skewed presentation of the sub-surface water. Take a look at the Reuters version of the story. The point of the story is that ice is moving around quickly (in terms of ice packs anyway) because of rapidly melting and freezing of ice thousands of feet below the surface. The coolness of the story was supposed to be about the new satellites that can detect the movement of the ice and map the water channels. Reuters makes it very clear here: "Global warming did not create these big pockets of water -- they lie beneath some 2,300 feet of compressed snow and ice, too deep to be affected by temperature changes on the surface -- but knowing how they behave is important to understanding the impact of climate change on the Antarctic ice sheet, study author Helen Fricker said by telephone." Let me repeat that first part, Global warming did not create these big pockets of water! But that's not the impression one gets from the AP story. I call global warmening shenanigans on the Associated Press!
