The whole business is eerily religious in feel. Back in the 15th century, the question was: Do you believe in Christ? It was required in Spain by the Inquisition that the answer should be affirmative, leaving to one side subsidiary specifications.
It is required today to believe that carbon-dioxide emissions threaten the basic ecological balance. The assumption then is that inasmuch as a large proportion of the damage is man-made, man-made solutions are necessary. But it is easy to see, right away, that there is a problem in devising appropriate solutions, and in allocating responsibility for them.
To speak in very general terms, the United States is easily the principal offender, given the size of our country and the intensity of our use of fossil-fuel energy. But even accepting the high per-capita rate of consumption in the United States, we face the terrible inadequacy of ameliorative resources. If the United States were (we are dealing in hypotheses) to eliminate the use of oil or gas for power, would that forfeiture be decisive?
Well, no. It would produce about 23 percent global relief, and at a devastating cost to our economy.
As a practical matter, what have modern states undertaken with a view to diminishing greenhouse gases? The answer is: Not very much. What is being done gives off a kind of satisfaction, of the kind felt back then when prayers were recited as apostates were led to the stake to be burned. If you levied a 100 percent surtax on gasoline in the United States, you would certainly reduce the use of it, but the arbiter is there to say: What is a complementary sacrifice we can then expect from India and China? China will soon overtake the United States in the production of greenhouse gases.
At Kyoto, an effort was made 10 years ago to allocate proportional reductions nation by nation. The United States almost uniquely declined to subscribe to the Kyoto protocols. Canada, Japan and the countries of Western Europe subscribed, but some have already fallen short of their goals, and all of them are skeptical about the prospect of making future scheduled reductions. It is estimated that if the United States had subscribed to Kyoto, it would have cost us $100 billion to $400 billion per year.
