scpg02 - I too am wondering if temperature proxies have it right. Let's not even talk about CO2 proxies!

I've been looking for any studies that have validated the proxy dataset to global temperatures calculated from modern climate stations. It seems it would be a valid excercise, and relatively straightforward. It would also give everybody some level of comfort about just how steady (or variable) our past temperature has been. Unfortunately, I have not found any such study.

I wonder why.........
