Opinion: Global warming not worth the fight

Global warming is real. It is predominantly anthropogenic. Left unchecked, it will likely warm the earth by 3-7 C by the end of the century. What should the United States do about it?
Very little, if anything at all.

It is not in our national self-interest to try and bear the costs of global warming by ourselves. For a wealthy, cold, non-agrarian, stable country such as ours, it is unclear whether we even stand that much to lose from a rise in temperatures. There have been several studies that suggest the costs of mitigating climate change exceed the benefits in a country such as the United States — work by William Nordhaus and Robert Mendelsohn of Yale, Richard Tol of Carnegie Mellon, Melissa Dell and Benjamin Olken of MIT, and others, suggest this outcome is likely.
But even if we take the estimates provided by the advocates of aggressive action, the math comes up short. For example, the National Resource Defense Council estimates that if left unchecked, global warming will cost the U.S. 1.8 percent of its GDP by the year 2100. Meanwhile the Stern Review estimates the cost of carbon mitigation to total 2 percent of world GDP by the year 2100. It appears that the hot areas of the world should be bribing us to take action, not the other way around.
More to the point, unilateral action will not mitigate climate change. The U.S. is only a small fraction of total emissions. Even if all of the Annex I countries of the Kyoto Protocol agreed to binding constraints, they would account for less than half of the world’s total emissions, and a far smaller fraction of the expected growth in emissions between now and 2100. To act unilaterally, or even in conjunction with the rest of the developed world, would mean paying the full measure of mitigating climate change while receiving only a fraction of its benefit.
