I'm a skeptic about any claim of understanding climate at this point, whether pro-GW or anti-GW. I just don't think the science is there, and I think the politics have gotten way ahead of where the science is. Having said that, I have problems with the use of proxy climate data, such as this author does with ice cores. While useful to start an inquiry, many times these things are overrated. Add to that the fact that everybody is able to grow their own "adjustment" functions to try to extrapolate the measurement to the climate at large, and having a discussion using data like this seems problematic, at least to me.
