In fact, the contribution of decreasing cosmic ray activity to climate change is almost 40 per cent, argues Dr. Rao in a paper which has been accepted for publication in Current Science, the preeminent Indian science journal. (drtimball.com)
Co2 levels also follow cosmic ray activity and solar cycle from peak co2 to peak co2. (judithcurry.com)
M. Funny how you limit the argument to the period of recent warming, conveniently overlooking the inconvenient truth that solar magnetic activity has been uniformly high over this period of warming and excluding the well documented climate history over the past centuries where sunspot activity, and cosmic ray activity, match climate history rather well.
