That's an obtuse and as yet unsupported scientific theory which in any case does not contradict the current consensus about anthropomorphic climate change. Nevertheless it will be picked up by professional science deniers to undermine efforts to stabilize the climate. Politicization of the climate issue will prevent that theory from ever being researched objectively. OTOH James Hansen created a climate model 40 years ago that predicted the current climate we live in and that should provide an adequate basis to control carbon, regardless of the merits of other theories.
