Your "alternative explanation" dates from 2005, and has since been shown to be unsatisfactory. That's not a criticism of you. The basis of science is NOTHING is settled. The laws of mass, motion and energy that comprise Newtonian physics, for instance, were validated by millions of experiments - but Einstein held that they were only *approximately* correct, and when speeds approach that of light, they are grossly in error. The important thing is scientists are free to challenge "facts", for if they prove the facts to be in error, we win, and if they prove the facts to stand up, we win. Our atmospheric measurements of greenhouse gas over the past half century has been taken at a volcano sitting in the middle of the Pacific. Given that the oceans absorb and give off more greenhouse gas than everything else combined, and volanism is another major player, isn't that data a bit suspect? Atmospheric levels of greenhouse gas were substantially higher in the past than in they are at present - and that was in the middle of an ice age. Does that suggest there may be other factors involved? Our sun is known to be a variable star. The word "variable" indicates that solar output is known to vary. If there's something going on - and like you, I suspect there is - wouldn't it make sense to learn what actually is happening? "Faith is believing in what you know damned well ain't so" -- Mark Twain. Excuse me, but I think we need more science, not less of it.
