I fully accept that global warming is real, human-caused, and a major problem in the coming century. However, I don't believe we should limit carbon emissions. Instead, we should earmark all the money that would've gone into reducing carbon emissions (a carbon tax could be useful for this) into developing comprehensive evacuation plans for every major city, as well as a fund for rebuilding. As the effects of global warming hit (which will more likely be in the form of severe weather events than a global rise in sea levels), we migrate away from the hardest hit areas and rebuild in the areas made more hospitable by climate change.
There are two advantages of this:
The first is that many climate scientists believe that it's already too late, and a tipping point was reached around 2000 that's set in motion a catastrophic climate shift that we can't reverse now. Cutting carbon emissions now is a bit like closing the barn door after the horses have left. It won't actually fix our predicament, though it may slow it.
The second advantage is that this covers a number of contingencies other than climate change. A freak hurricane sweeps up the Gulf Coast, headed for Houston or New Orleans? No problem, all of the evacuation routes have been mapped out, we've built enough roads that the population can get out (as an additional plus, this helps rush-hour traffic), and the insurance companies are ready to pay out to help the victims. Drought in California? Move to Seattle or Portland and stop buying beef and almonds. It'd help if we let the price of affected commodities (water, and the things it helps grow) float to reflect their true scarcity rather than subsidize them.
The idea is to fix the problem closer to the symptoms rather than trying to get to the source. Accept that the planet's climate will change, and then work to adapt to that with minimal dislocation rather than prevent it from changing.
Thoughts? It's certainly not the party line, but it makes sense to me. And if you're currently a climate-change denier, would this proposed solution make you reconsider the facts?
