“A reply to Vonk: Radiative Physics Simplified II“. Denialist Jeff Id from “the Air Vent” tries to explain to the more enthusiastic followers of Anthony Watts’ blog why they shouldn’t make themselves look foolish defending Tom Vonk’s recent imaginative foray into radiative physics.

My statement is – CO2 does create a warming effect in the lower atmosphere.

Horrors! But the usual escape hatch is attached:

Before that makes you scream at the monitor, I’ve not said anything about the magnitude or danger or even measurability of the effect. I only assert that the effect is real, is provable, it’s basic physics and it does exist.

Lasers and canisters of CO2 explain it all. Source: WUWT figure 7.

After some simple-minded talk about lasers and canisters of gases Jeff declares that “NONE of this should create any alarm” and says that perhaps “CO2 then, can be considered nothing but plant food”. And of course we all must be reminded why the “true and high quality results from Anthony’s surfacestations project [is] so critically important.”
