Habibullo I. Abdussamatov of the Pulkovo Observatory of the RAS thinks solar irradiance is in for a “bicentennial decrease”. And has been kind enough to predict it. Unfortunately it won’t be obvious until about, what, 2016, that he is hopelessly wrong. But it beats most of the nutters who just wurble and nitpick and never predict anything.
