This is in some ways a game of semantics. The Iris hypothesis was proposed in conjunction with Lindzen's observation that there is no cause for concern from CO2.
Actually, it is far more than semantics. Lindzen's position is completely incompatible with arguments put forth in this forum by many of the people you are defending.
To claim it is semantics is to claim that the distinction between 'the twin towers were brought down by explosives' and 'the twin towers were brought down by plane-shaped missiles' is semantics. I use this example not because I want to compare the arguments in this thread to the truthers, but because that is the only place where one can find logic that asinine.
If Lindzen is right, then all the positions put forth by MHaze, AA, Beerina, et al are completely, utterly, wrong. You cannot point to Lindzen and say 'well, he's wrong about 98% of the things he says, but hey, his conclusion roughly agrees with mine if I squint a lot, so he's totally right.' To call this distinction
semantic is to display a complete and total lack of understanding of the meaning of that word.
I repeat - the difference between the Iris hypothesis put forth by Lindzen and the 'conventional' global warming hypothesis is whether, in Cirrus Clouds, the ratio of infrared energy reflected to earth versus the solar energy reflected to space, and whether increased heat in the oceans will increase the number of clouds or reduce them (Lindzen's hypothesis is they are a net warming effect, and the warming in the oceans will reduce them). This is the difference.
You cannot seriously tell me that this is the
same thing as Beerina's question on whether manmade CO2 is even significant. I dare you to tell me they're the same thing, and that the difference is
semantic.

I'm not sure if you call that "denying" or not (too bad people still use that label; it's pretty much an appeal to ridicule at this point).
It's hard to appeal to ridicule when deniers work so hard to make themselves ridiculous. To see them jump from hypothesis to hypothesis, embracing things like Lindzen when he disagrees with 98% of the crap they spout, how can one ridicule this? It surpasses ridicule, and moves into farce.
It is indeed fortunate for Lindzen that he has largely escaped censure. Other subjects named in the hacked emails were not as fortunate.
The NWO will get to him eventually, amright?
