They Call It A "Non-Polluting Gas"...

This Open Letter would have rather more credibility if this phrase

The United Nations Intergovernmental Panel on Climate Change (IPCC) has issued increasingly alarming conclusions about the climatic influences of human-produced carbon dioxide (CO2), a non-polluting gas that is essential to plant photosynthesis.

didn't sound suspiciously close to this one:

As for carbon dioxide, it isn't smog or smoke, it's what we breathe out, and plants breathe in. Carbon dioxide: they call it pollution, we call it life.

Because that, as I wrote some time ago, was an egregious bunch of propaganda for the joys of pollution provided by the Competitive Enterprise Institute (CEI), "advancing liberty - from the economy to ecology".

And oh, look: by an amazing coincidence the Open Letter talks about - guess what? - yes, that precious economy:

While we understand the evidence that has led them to view CO2 emissions as harmful, the IPCC’s conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity.

Ah, yes, prosperity - so much more important than little things like trees, a healthy, sustainable environmental commons, or survival. No, let's get our priorities right:

Attempts to prevent global climate change from occurring are ultimately futile, and constitute a tragic misallocation of resources that would be better spent on humanity’s real and pressing problems

which are, of course, how to make the rich even richer by exploiting the environmental commons as quickly as possible, before the world is burnt to a crisp.
