This is exactly correct.

Not to mention, some studies suggest that global warming is nowhere near what it should be (and I agree, all the estimates I have calculated suggest the global average temperature delta should be at least another degree higher). The reasons for this are varied, ice caps melting and such, but one key reason is that industrial activity also releases aerosols into the atmosphere which reflect solar radiation back into space. This was described as a "fool's climate" and stopping burning of fossil fuels could result in further global warming as the aerosols are removed. But they also have a much shorter half-life than greenhouse gases so your damned if you do, damned if you don't.

Even taking into account that study's very optimistic statement of 30%, and another study's very optimistic assessment of climate change being driven by thermal pollution (which is a quite reasonable theory), you are looking at at least 0.5 degrees of warming, which is... fine, but suboptimal. Realistically, we should anticipate at least 2.5 to 4.5 degrees of warming by the turn of the century.

Moreover, bug and larger animal populations have largely collapsed in recent years, which is key in food production (although I am not as well versed on that literature). While Eco-fascism is bad, we seriously need to start from the position of "we're fucked."

It's been linked here already (and thanks to a404 for posting it!), but Desert is really a must-read.
