In response to the Trump administration’s announcement that it was pulling out of the Paris Climate Accord, some of his critics declared that anyone who likes “science” would have supported the accord.
Not surprisingly, astrophysicist and science commentator Neil deGrasse Tyson rushed to declare that Trump supported the withdrawal because his administration “never learned what Science is or how and why it works.”
But what does “Science” (which Tyson capitalizes for some reason) have to do with it?
We know that Tyson is of the opinion that there is global warming. We also know that many other physical scientists agree with him.

After all, the Paris Climate Agreement isn’t a scientific study. It’s a political document that lays out a specific public-policy agenda.
Agreement or disagreement with the accord might hint at one’s opinions about climate science. Or it might not. One can agree that climate change exists and that human beings have a large role in the phenomenon. Agreement on this matter, however, does not dictate that one must also agree with the political policies outlined in the Paris document.
The two are totally independent phenomena.
Science and Politics Are Not the Same Thing
An analogy might help illustrate further:
Scientific inquiry tells us that obesity is bad for one’s health. Let’s imagine then, that in response to rising obesity rates, a large number of politicians gather and sign an agreement — let’s call it the London Obesity Avoidance Deal (LOAD). The supporting politicians claim that the deal will reduce obesity and that failure to abide by the agreement will spell a health crisis for humanity.
Does this mean, then, that any politician who doesn’t sign onto the agreement is an “obesity denier”? Does a failure to approve of the agreement prove that the dissenters believe that obesity is not a real thing?
Those who refuse to sign the agreement may be of the opinion that the LOAD does little to actually reduce obesity. Or, the dissenters may feel that the deal fails to properly compare costs and benefits when imposing its directives. Opponents may feel that “the cure is worse than the disease.”
In any case, dissent from the deal has nothing to do with denying the existence of obesity or the science behind the studies on the matter.
The Problem with Paris
The same is true of the Paris deal. Those who disagree with it may very well be — and probably are — taking issue with the specific provisions of the deal which may actually prove to be more costly to people than the presumed global warming itself.
But, for physicists like Tyson — i.e., people who know nothing about economics or political institutions — public policy is like a magic trick. A group of politicians get together, declare that they’re going to solve problem X, and then problem X is magically solved, so long as everyone supports the “solution.”
But what if the policy prescriptions of the Paris politicians are wrong? Or, what if the cure is worse than the disease?
Presumably, the agreement is supposed to improve the lives of real-world human beings by improving their standards of living.
If this is true, then, the Paris agreement must accomplish several things:
1. It must rely on good science about the climate.
2. It must accurately predict the effects of climate change on standards of living.
3. It must endorse public policies that will do something to mitigate the negative effects of climate change on standards of living.
4. It must demonstrate that these public policies will in fact mitigate the effects of climate change.
5. The agreement must demonstrate that the costs of the proposed public policies themselves are lower than the costs of the climate change.
If the Paris agreement fails to do any of these things, it should be rejected. If the net effect of the agreement is to make people poorer, then the agreement is of no value.
Now, without making any judgment about climate science itself, we can see just from looking at the Paris agreement that it could easily be rejected on the basis of numbers two, three, four, and five in our list.
After all, the agreement is based on policy predictions that are wildly speculative.They attempt to make predictions about the global economy decades in the future (a notoriously unreliable endeavor) and they fail to honestly take into account the true costs of imposing far-higher energy costs on most of the world’s poor and working classes — which is what the agreement would do.
In fact, the agreement doesn’t even mention the cost to households that would face higher energy costs under the agreement. The only costs mentioned are the costs of adapting to climate change. In other words, the agreement assumes that there is no downside for households in the agreement’s provisions. That’s a huge red flag right there.
Also ignored is the opportunity cost of adopting the agreement’s provisions. In real life, adoption of the agreement’s policy prescriptions will lessen growth by reducing access to basic energy resources. In addition to reducing household wealth, this will also reduce tax revenues. Money spent on higher energy costs is money that can’t be spent elsewhere — on things like health care, and research into better agricultural practices. Yet, at the same time, the agreement calls for massive redistribution of wealth and large amounts of government spending on various programs such as “emergency preparedness” and more government “insurance” to pay for the effects of natural disasters.
Thus, the agreement calls for more spending, while reducing the ability of both the public and private sectors to engage in that spending. It’s a self-defeating endeavor.
Other opportunity costs include the impact on the production of fresh water. As I noted in a 2015 article
“A second major factor here in the necessity of energy is fresh water. The California drought has reminded us that fresh water is a scarce resource, even if the government likes to treat it as if it were not. But even as larger populations demand more water, fresh water can be produced through the use of energy via desalinization and pump-based aqueducts.
Today, most such schemes are still uneconomical because the problem of water scarcity can usually be solved through cheaper means such as importing food from wetter climates and through cheaper aqueduct systems that are primarily gravity-based.
In the future, however, as water does become more and more scarce as populations grow, the most practical answer will indeed become more energy-intensive solutions.
By centrally planning and artificially limiting energy usage, however, what the global warming lobby wants to do is raise the price of water processing, and by limiting the use of such methods, also inhibit technological progress by preventing practical experience in the use of water processing and fresh water production.”
The Paris Climate Agreement supporters will no doubt retort that the provisions of the agreement will somehow amazingly prevent the need for more spending on clean water in the future by reducing global temperatures. Based on what evidence? Based on a computer model for what will happen decades from now?
With such flimsy evidence, it’s easy to see that it might be wiser to stick with policies we have now that are likely to produce a bird in hand — rather than the two birds in the bush merely promised by the Paris agreement.
We already know we can help the poor now with cheap energy, more productive capacity, and a robust economy. The Paris agreement only promises to help hypothetical people in the future based on a theoretical and untried public policy regime.
Many prudent people will elect to go with the former.
Moreover, many of the global warming lobby’s own people deny that the Paris agreement does much of anything to reduce temperatures anyway. Thus, prudence would dictate a renewed interest in investing in technologies and poverty-relief measures (such as those that encourage more trade and capital investment) that we know will help the poor right now. Adopting policies that cripple our ability to invest in these measures — as the Paris agreement does — only makes matters worse.
Nevertheless, in the imaginary world of physicists and climate scientists who can’t comprehend the complicated realities of economics and public policy, simply wishing something to be so makes it so. If we just wish really hard that all our problems are solved, surely the good people in government will make it happen.
