As somebunnies may have noticed, the CO2 is life, or plants or green line is being peddled by the denialati. It was the one line Will Happer remembered to peddle during the recent Cruz farago. Indur Golkany, beloved of Roger Sr. even wrote a paper about it that was peer reviewed (does that mean Chris Monckton? Why yes it does, and Happer even told Greepeach about it and how peer review works on his side of the aisle).
Bernard J has an excellent deconstruction of the Cruz four in the comments to a previous post. Suffice it to say he would rather discuss climate change with pond scum than Mark Styne but one point stood out.
The next time somebunny tells you between the 5th and 12th floor that CO2 is not a pollutant because we breath it out reply:
Right. There's a reason why we breathe it out... We also shit, and shit is also great for plants, but too much of it in too constricted an environment...
