Hi Danescombe

Important post indeed. Actually I�m preparing one using this image.. but it�s going to be different anyway (I�ll to use a part only).
I really think we have much to do with this problem, I mean the heat we are producing over the world. There is too much to talk about. Let me suggest this post I�ve made about some glaciers over the world that shows the same problems that you introduced here, so people interested in this issue can have more info. Thanks!
