In fact, it seems as if it isn’t really much of a debate anymore
First, let me be clear, the debate among scientists isn’t whether CO2 is a greenhouse gas or whether, even, it can cause warming, but instead on what real (if any) total effect it has overall on the climate. In other words, is there a saturation point where additional CO2 has little marginal effect, or does it build to a tipping point where the change is radical? Robust climate or delicate climate?
Evidence is building toward the robust climate theory, which would mean that while there may be more CO2 being emitted, it has little to no effect on the overall climate. That, of course, is contrary to the AGW crowd’s theory.
