Description
Summary:reviewer needs to be specific as to where this fits. Preference goes to peer-reviewed literature. 7-2 7 0 This chapter is considerably improved from the ZOD, and I commend the authors for constructing a draft that is more balanced, better organized, covers most of the important issues, and is well written. That having been said, there are still differences in approach and emphasis among the individual sections on clouds, aerosols, and cloud-aerosol interactions. The chapter as a whole would benefit if these differences were reduced. The clouds section, with one exception noted in a future comment, really focuses on the climatic effects of clouds and eschews detailed discussions of the cloud physics that leads to these climate effects, so much so that some of the more important science issues are ignored and others given short shrift. The aerosol section is just the opposite- it reads more like a review article in a journal than an IPCC report section, reviewing all the details of aerosol physics/chemistry, including many things that may or may not turn out to be significant in the future but which have not yet been demonstrated to be important to climate change. It seems to this reviewer that the cloud-aerosol interaction section comes closest to getting the balance right between explaining details of the physics and explaining how they are understood to affect or not affect climate change. The section on cosmic ray effects on climate is too long given that there are as yet no demonstrated, or even likely, effects on
