I was in Iceland a few weeks ago, spent a few days touring round looking at things including glaciers. There are a few big permanent ice cap type things with various glaciers passing down through surrounding mountains from them. I cannot recall the exact distances but guides told us that those that we saw were now several kilometres shorter than they were a few years back. It's not proof of climate change but it would seem to indicate that something is happening. Im not interested in getting into an argument about the pro's/cons of it, just my 2 cents.
