President Trump announced the U.S. will withdraw from the Paris climate agreement on Thursday, to the horror of green elites world-wide. If the decision shows he is more mindful of American economic interests than they are, the other virtue of pulling out is to expose the fraudulence of this Potemkin village.
In a Rose Garden ceremony, Mr. Trump broke with the 2015 agreement, starting the formal four-year withdrawal process: “We’re getting out. And we will start to renegotiate and we’ll see if there’s a better deal. If we can, great. If we can’t, that’s fine.”
This nonchalance inspired a predictable political meltdown, with the anticarbon lobby invoking death, planetary disaster and a permanent historical stain. Billionaire Democratic donor Tom Steyer called it “a traitorous act of war against the American people,” while Barack Obama accused his successor of joining “a small handful of nations that reject the future,” whatever that means. Get ready for another march on the White House.
But amid the outrage, the aggrieved still haven’t gotten around to resolving the central Paris contradiction, which is that it promises to be Earth-saving but fails on its own terms. It is a pledge of phony progress.
The 195 signatory nations volunteered their own carbon emission-reduction pledges, known as “intended nationally determined contributions,” or INDCs. China and the other developing nations account for 63% of annual global CO 2 emissions, and their share is rising. They submitted INDCs that pledged to peak the carbon status quo “around” 2030, and maybe later, or never, since Paris included no enforcement mechanisms to prevent cheating.
Meanwhile, the developed OECD nations—responsible for 55% of world CO 2 as recently as 2000—made unrealistic assurances that even they knew they could not achieve. As central-planning prone as the Obama Administration was, it never identified a tax-and-regulation program that came close to meeting its own emissions pledge of 26% to 28% reductions from 2005 levels by 2025.
Paris is thus an exercise in moral and social signaling that is likely to exert little if any influence on atmospheric CO 2 , much less on global temperatures. The Paris target was to limit the surface temperature increase to “well below” two degrees Celsius from the pre-industrial level by 2100. Researchers at the Massachusetts Institute of Technology’s Joint Program conclude that even if every INDC is fulfilled to the letter, the temperature increase will be in the range of 1.9–2.6 degrees Celsius by 2050, and 3.1–5.2 degrees Celsius by 2100.
Such forecasts are highly uncertain, which is inherent when scientists attempt to predict the future behavior of a system as complex as global climate. The best form of climate-change insurance is a large and growing economy so that future generations can afford to adapt to whatever they may confront.
