If back radiation from "water clouds" overwhelms the greenhouse effect of CO2, why is the planet warming so fast? If your hypothesis was correct, the current warming rate would be consistent with historical and proxy records.  And it's not, not at all.

Also, what role do these researchers see for greenhouse gasses in ending ice ages? In other words, the greenhouse effect accounts very neatly for the well-documented cycle of ice ages and interglacials. If  the presence/absence of CO2 in the atmosphere plays no significant role in regulating global temperatures, what does? Water vapor? 

You might consider that water vapor is a greenhouse gas too, and, although it's statistically of a much greater volume than CO2, it's an effect of temperature as well as a driver of it. The journal you link is not really a serious scientific journal, anyhow. It's on SourceWatch's radar as publishing substandard research from habitual deniers.
