The science is a settled as it needs to be -- the remaining questions are about details and amplifying forcings, etc. But the big picture is *very* clear -- anthropogenic climate change is upon us.
The sun and clouds and all the rest are already fully accounted for in the science -- *please* take the time to view the series of videos I linked to.
Edit: here's another video debunking the "mini-ice age":
To ignore the scientific consensus is folly. We need to change our energy sources, and we need to dump factory farming, and disposable stuff (designed for the dump!) and we need to stop pretending that we are not part of the environment. The earth is a finite planet, and a growth economy is a fallacy, and oil was the Viagra of our little economic party.
What kind of world are we leaving to our descendents?
