I've more than once seen, and gotten peripherally involved in, discussions on this subject, but the last time I looked at it in any depth was (now that I think back) more than 10 years ago.
People on BOTH sides have been so strident that I find it very hard to even sort out the sane from the kook, and I'd really like to have a decent overview of the subject... on both sides.
I would prefer this *NOT* become a debate in my journal. What I want are references that allow me to examine the major sides of the debate -- best case, worst case, strength of evidence, etc.
Last I looked, for instance, I saw no clear indication that there was a really good plot of temperatures for, say, the past 100,000 years which would therefore permit one to see if the current temperature trends really fell out of those bounds. After all, 100-200 years is a miniscule blip on the charts.
So I'm looking to update my knowledge -- preferably with few flames.
