The co2 warming effect is not in discussion, as you say. But there are cascades of events stemming from the warming itself, and those are integral part of our concern with climate change. How much sea rise will there be? How much will the weather patterns change? How, and how much this will impact catastrophic events? Which negative (or positive) impacts there will be on economies? And of which countries' economies? What will be the ecological impacts? What will be the impacts on health, on infectious diseases? What will be the societal impacts? Etc. Some of these effects are two or three or more steps removed from the warming caused by co2, and there is a "cascade of uncertainty" in predicting them. I agree with the GP that being climate (and atmosphere) omnipresent, it is easy and tempting to draw long causal chains from it to the most disparate effects. And that, given the theme is central to our time, and given the number of scientists of all disciplines working to study these effects, in the most rigorous fields a publication bias on the effects found must exist. In the less rigorous, most probably anything goes.
