Now Real Climate has posted a summary and FAQ by Shaun Marcott and colleagues, which I’ll excerpt below. As the real climate scientists at RC note:
Our view is that the results of the paper will stand the test of time, particularly regarding the small global temperature variations in the Holocene. If anything, early Holocene warmth might be overestimated in this study.The main, stunning conclusion we can draw from the paper is that the rate of warming since 1900 is 50 times greater than the rate of cooling in the previous 5000 years, which undermines the whole notion of adaptation..."

2) The history of climate science. We have nearly 200 years of climate science starting with Joseph Fourier who first considered "the possibility that the Earth's atmosphere might act as an insulator of some kind" and first proposed what is now known as the greenhouse effect.
Over the years we have had Tyndall, Arrhenius, Callendar, Plass, Suess, Revelle, Keeling, Charney, Lovelock, Hansen, Broecker, Oreskes and Schneider, to name but a tiny few of the important figures who have made significant contributions to climate science. Most of us will leave little record of lasting import that we were here or did anything of significance for humanity. Unlike these giants of science. Climate change deniers must deny the very history of the science that has brought us to this moment. In fact, the less they know, the better. If they actually studied and understood climate science, they would not be deniers..."
