The IPCC’s estimate of costs for reducing emissions out to 2050 in order to stabilize CO2 levels at the lowest level that they considered (which I believe was about 445-535 ppm) was a reduction in GDP growth of less than 0.12% of GDP a year. So, in other words, if you assume that world economic growth would have been, say, 3% per year, then these costs would reduce the growth to ~2.88% per year. (See here, in particular Table SPM.6 on p. 18 of the Summary for policymakers.)

Interesting. Of course the devil is in the details. I haven’t heard that anything so modest is what’s required to halt or slow down GW…in fact, all I have heard is that we are on the bring of disaster, etc etc, and that only extreme measures will get us through. If the US can do this for less than .12% of GDP then I have to wonder…why aren’t those figures being put forth more? I mean…that has got to be somewhere in the ball park of, say, NASA’s budget I should think.
I’m a bit skeptical that this low end figure is what we are really talking about here…because if it is, it makes no sense why we aren’t doing it already. And why the Euro’s are having so much trouble meeting their own quotas. And why other countries aren’t jumping at the chance to do this for such a paltry amount. We are only talking about a few hundred billion dollars if my rough back of the envelope calculation is in the ball park.

I hardly think that qualifies as “major economic depression, mass[ive un]employment and grinding powerty”.

Certainly not…if in fact the estimate you are quoting is both encompassing, accurate and inclusive. I’m a bit skeptical as I said…simply because every show I’ve seen on GW (and we are talking about a hurricane of recent shows on this subject) points to it being a bit more than what you are indicating to halt or avert this impending disaster.

There are people out there who want you to think that the only two options are to do essentially nothing or to face economic ruin. However, those tend to be the people who are, in one way or another, connected to industries (like coal) who will likely be losers in a carbon-constrained world, or people who have a viceral hatred of almost any government regulation of the market.

Interestingly enough, there are ALSO people and groups out there who are using the fear of GW/AGW to push through their own anti-corporate/green/tree hugging agendas as well. Fancy that…on both sides of the debate there are people who have other motives for all this stuff.
