Its fish in a barrel time, but Corbyn seems to have had his International Conference. It doesn’t look very exciting. As RB says: Did the meeting live up to its billing of “refuting, totally, the CO2 theory of warming”? Hardly. Because doing that seriously doesn’t mean refuting it to my satisfaction, or yours, or that of the audience scattered about the Imperial College lecture theatre on Wednesday; it means convincing the greater community of climate scientists, and that brings us back to… publishing. What some in the sceptical camp do not appear to appreciate is that published, peer-reviewed science is not only the sole way of establishing and improving theories; it’s also, now, the only route to the policymakers they want to influence. Modern-day ministers and their scientifically-qualified advisers are absolutely not going to listen to half-developed, unpublished theories or complaints about fraud and conspiracies.
