why can't the AGWCult produce a single lab experiment that controls for incremental and minute quantities of CO2?
Are you asking for something new? Did you get tired of lying about the 120 ppm experiments you'd been shown?
there have been no 120 ppm experiments shown. I would have noticed.
there have been a few other CO2 experiments for other than 120 ppm that have been faked though. like the Al Gore/ Bill Nye one. Al Gore and Bill Nye FAIL at doing a simple CO2 experiment Watts Up With That
