Global Warming and Solar Flares

[cbish]

Does anyone have any information on this? A friend of mine received a paper which said global warming is caused by solar flares. IIRC, this is not true. It seems I remember reading a response on this forum explaining why, but doing a search on this topic on this forum is a daunting task.

I think we'll have to be clear on this. The claim is that most of the climate change is natural in origin, and there have been compelling empirical studies which appear to show a correlation between solar variation and climate change. Most of the claims of anthropogenic climate change appear to come from computer models (or more accurately, from the people who program the computer models).

Abstract
Possible mechanisms of solar-climatic connections, which may be of importance over short and long time intervals, are discussed. The variations of energetic balance of Earth's climatic system for the last 50 years are estimated. It is ascertained that the imbalance between the flux of solar energy that comes to the Earth and radiates to space is of 0.1% for the last ten years. The significance is analyzed for the possible influence of variations of solar constant upon the energetic balance of the atmosphere. The physical mechanism of the influence of solar activity on climatic characteristics and the atmospheric circulation is suggested and theoretically substantiated. The mechanism is based on the redistribution in lower-troposphere of condensation nuclei by the vertical electric field. This electric field is determined by the ionosphere-Earth electric potential, which in the Polar Regions is controlled not only by tropical thunderstorms and by the galactic cosmic-ray intensity but also by solar cosmic-ray fluxes. The height redistribution in the atmosphere of condensation nuclei with a change of the electric field of the atmosphere is accompanied by a change in total latent heat (phase transition of water vapor), by changes in radiation balance, and by subsequent changes of the thermobaric field of troposphere. The results of analysis of thermobaric field variations for the periods of invasion of abnormally powerful solar cosmic ray fluxes and magnetic storms confirm the reality of manifestation of heliogeophysical disturbances.
