There is a big controversy in climate science regarding the magnitude of the effect of solar variations on the earth's climate. This article discusses one of those controversial theories.
I recently found this incredibly interesting article on the internet by K. Lassen at the Danish Meteorological Institute. The article shows incredible correlations between global temperatures and solar cycle length. Interestingly the author above and a colleague published evidence for this theory in Science way back in 1991. Although not the point of the article, it strongly implies that historical temperature variations are predominantly the result of a changing solar cycle length. Plots provided by K. Lassen (see link above) imply that the solar cycle length is periodic and it appears as though we might be near a peak in the periodic signal - thus cooling would begin (we just finished an unusually long cycle). If the solar cycle length is lengthening and world temperatures are still rising then human caused global warming may be even more significant than expected! If the solar cycle length is just starting to drop and world temperatures are also dropping accordingly (or start dropping soon) then human caused global warming might be much smaller than thought.
Check out this plot I got from this site, it shows that global temperatures are highly correlated with the sun spot cycle length.

September 24th addition: I will release my book soon and it includes many non-handout based suggestions for how to help with the food crisis.
