The follow is a published review paper by J. Kirkby that summarizes the data and analysis that supports the assertion that solar magnetic cycle changes which modulation planetary clouds is a first order climate forcing function.

Kirkby includes 170 published papers to support the solar magnetic modulation of clouds hypothesis.

Is there any thread in against ATM that has 170 published papers to support it?

Is 170 published papers sufficient evidence that the mechanism in question is not ATM?
