Doug:

What dio you suppose accounts for the unprecedented calving of icebergs in the Antarctic which hyave been intact and growing for thousands of years?

How do you explain the softening of permafrost layers which have been solid ice for thousands of years?

How about the gradual disappearance of real estate from the edges of low-lying islands in the near-Arctic regions?

Or, perhaps you have an explanation for the dramatic reduction of firm ice which is disrupting the economy of hunters of Eskimo tribes in certain regions which are usually solid enough to hunt on byut have now become so mushy year-round that they are having to give up practices that have kept their tribes alive for centuries?

All these phenomena and more are carefully documented in the New Yorker series to which I offered a pointer. I am sure your library in Pheonix has the back issues.

Just in case you want to arm yourself with the facts.
