Nay-sayers for nay-saying's sake
"The theories about the water could drip through and accelerate ice sheet flow into the water "...is EXACTLY what has been observed in Greenland over the last couple of years, with Greenland's Glaciers accelerating and decreasing in size as a consequence.
NASA's observation is an interesting one which gives us more data to understand the effects of climate change: warming seas produce increased precipitation over Antarctica, summer melts change this snow into ice.
Too much summer melting could make the glaciers move faster, of course.
So will the increased precipitation over Antarctica reach a balance with increased glacier flow, or will one outweigh the other?
Luckily there are climatologists and others out there who are looking into these questions.
I don't see the point of nay-saying the whole "Global Warming" thing. Of course nobody's going to notice an increase of 1degree. Of course journalists are incapable of reporting intelligently on any science issue (El Reg excepted, of course). What people will notice is if their own neck of the woods suffers huge changes to its climate - and that's what we should be looking out for.
Have you ever been to Brittany?
Get a map of the world and trace the latitude West from Brittany until you hit land again. Now imagine Brittany and Newfoundland exchanging their climates. Now imagine this happening in 3rd-world countries where people haven't the means/intelligence/industry to overcome a change like this: where are they going to go, and who do you think is going to pay for it?
Climate Change *is* real, it's not simple, and its effects are going to be quite shocking, even to people like us.
