Thanks for an interesting link. I don’t post on climate change, because I don’t feel that I know the science well enough. Two points: First, I wonder how they know the sunspot activity for periods long in the past? I don’t say they can’t, I just wonder what the technique would be. Second, I agree with Motive’s comment that when the sunspots return we could be in real trouble. The article is properly inconclusive, but this seems to be something to keep an eye on.
