Solar and climate- no longer taboo

R. Gates says:
In general, the life support systems of the earth (which include of course biosphere, hydrosphere, and all levels of the atmosphere) are self regulating and adjust to external forcing to keep earth in a range of temperatures that are not too extreme for life. This range can be quite large, as life can be quite adaptable. However, when change strikes rapidly, or too intensely, the self-regulating processes of the planet don’t have time to react or adapt, and we get periods of mass extinctions on the planet, and the planet goes through a period of reorganization until new self-regulating systems can once more balance things out and a new mode is established, with much different biosphere than previously.
The key question arises: How sensitive will the biosphere, atmosphere, and hydrosphere be to the (geologically speaking) rapid rise in CO2 beyond anything seen in at least 800,000 years? As a current “warmist” I think human CO2 emissions are having some effect, though I am still not convinced they will be catastrophic. However, it does appear that some changes going on in the oceans (hydrosphere) and specifically the biological ecosystems of the oceans might be indicating that the oceans are going through some rapid changes. This deserves close and intense study, for as the oceans go, so goes much of the rest of life on earth. The greatest mass extinction on earth was seen first as changes in the oceans.” —http://wattsupwiththat.com/2011/10/13/solar-and-climate-no-longer-taboo/#comment-769828
