2013 Peer-Reviewed Study: ‘Contribution of the greenhouse effect of carbon-containing gases to global warming turns out to be insignificant’ – By S. V. Avakyan, writing for the Herald of the Russian Academy of Sciences
The Role of Solar Activity in Global Warming," by S. V. Avakyan. It appeared in the Herald of the Russian Academy of Sciences, 2013, Vol. 83, No. 3, pp. 275–285. Dr. Avakyan is "Head of the Laboratory of Aerospace Physical Optics at the Vavilov State Optical Institute and a leading researcher of the RAS Central (Pulkovo) Astronomical Observatory."
The abstract reads: 'The author associates the recently observed climate warming and carbon dioxide concentration growth in the lower atmospheric layers with variations of solar–geomagnetic activity in global cloud formation and the significant decrease in the role of forests in carbon dioxide accumulation in the process of photosynthesis. The contribution of the greenhouse effect of carbon-containing gases to global warming turns out to be insignificant.'
