| I don't think it's the rise in temperature that is the problem-it's the rate of change. When we were in Iceland a couple of summers ago we were at a camp at the foot of their major glacier and they had a centre there which explained all about the expansion and contraction of the glacier. The ice field had been much bigger in the 1800's, but much smaller (than it was now) in the 1200's-well there wasn't much in the way of atmospheric polution around then simply because there weren't many people either. The climate on this little planet of ours has continually changed over the milenia-just this time it is happening a bit quick like.
