Recent retreats in ice in the Alps due to global warming have resulted in a number of interesting archological finds, of which the most famous is the "ice man", Otzi. Less famous are the finds in Schnidjoch Pass. These have been purported by AGW deniers to prove that the Alps were warmer in the past when the artifacts found in Schnidejoch were dropped by their former owners. In fact, the logic is exactly the reverse - these artifacts prove Schnidejoch to have been colder throughout the last 6000 years than it has been in the early twenty-first century. Here is a detailed explanation of why, from a recent comment at SkS. A follow on comment, not posted here, is also of interest.

The following is a comment made at SkS on the topic of how much new agricultural land will be made available in northern latitudes by global warming. It relies heavily on just one, twenty year old reference in an area in which I lack significant knowledge. It is posted primarily to provide a reference to two key sources of relevant data. I think my discussion is reasonable, but it should only used to provoke thinking on the topic rather than to take home conclusions.
