Global warming blamed for advancing glacier

The Daily Mail reports that global warming is changing the face of the northern hemisphere, and presents these photos of Iceland's Breidamerkurjokull glacier as evidence.

Trouble is, glacial retreat would be more indicative of global warming than a glacial advance, and in reality neither would be a conclusive indicator of global warming or cooling because glaciers grow when they get lots of snow in the winter and not much melting in the summer, a situation which could be attributable simply to changes in cloud and precipitation patterns rather than temperature.

But that doesn't much matter. The point of this post is to observe an example of the knee-jerk tendency of the media and the public to lay every natural change at the feet of "global" "warming". It does get tiresome.
