Lots of nutsy "skeptics" here
Yes, of course the Sun affects the Earth's climate. Every climatologist knows this is the case.
The question is how would changes in solar radiance affect the climate? At what levels of the atmosphere? How would the global climate effects of changes in solar radiance be differentiated from changes due to atmospheric changes? Are there any differences that can be used to examine the competing hypothesis? (Hint: yes, there bloody well are!)
So-called anonymous coward "skeptics" here seem very happy to toss around the rawest nonsense both for their own position and the position they attribute to the climatological community.
