Anthony Watts records the release of a new paper by Shaun Lovejoy of McGill University, which claims to have shown that the chances of recent temperature change being natural are close to zero.
With 99% certainty claimed for the results, all sorts of alarm bells are sounded, and sure enough holes are being picked in the results already: Monckton here and Matt Briggs here.
I think it's fair to say that this particular paper is going to sink without trace.
