Study finds global warming over past 4 centuries was due to increased solar activity
Posted by greg2213 on June 6, 2011
A peer-reviewed paper published in the Journal of Atmospheric and Solar-Terrestrial Physics finds global warming over the 20th century “not significantly different” from warming episodes that occurred in earlier centuries. The paper finds that the increase in solar activity over the past 400 years explains the warming, without any need to search for a unique cause of late 20th century warming, such as greenhouse gas concentrations. The NIPCC website just posted this summary of the paper:

The paper is not behind a payway, so click the link above to get the link to the PDF. Given that papers of this sort have a much higher bar to pass than alarmist supporting papers I’m going to assume that it’s pretty solid. Conclusive? Who knows. A pretty good piece of research, yes.
A slightly variable sun causes warming of the surface and atmosphere which causes airstreams and currents which are affected by the physical location and shape of the landmasses and the Earth’s rotation, day night cycles, and a few other things. Somewhere CO2/methane might have something to do with it, but that’s looking less likely as time goes on.
One of the issues with the Global Warming concept is the lack of explanation for prior warm periods, warmer than the current period, when CO2 could not have been the driver. And if it was then we should be seeing seriously warmer temps today. We’re not.
Additionally, there is the lack of explanation for why the planet didn’t burn up in past ages when CO2 was far higher than today’s measly concentration. In fact, life flourished back then. If the CO2 concerns were real then we’d be seeing significantly higher, to much higher, temps today and at least some of the hysterical remarks would be coming true. At little bit, anyway.
As it is, all of them can by put into the “The End is Near” bin of failed religious cult predictions. 100% fail rate. If we need to mend our ways then the accusing side should have some credibility, I think. So far, they have none.
As far as I’m concerned, the sooner we got off the “CO2 is bad” kick, the better.
