The Church, climate change, and the shadow of Galileo
By Phil Lawler ( bio - articles - email ) | Jun 19, 2014
Do you want to know what I think about climate change?
My formal training in the sciences ended 45 years ago, with an introductory course on geology. I do not attend scientific conferences; I do not read scientific journals. I do not understand the methodologies of measuring and modeling. (In all these respects, incidentally, my ignorance is roughly equivalent to that of a typical American politician, or an average Catholic bishop.) So I (and they) have no business offering opinions on a scientific matter.
But this much I do know about the topic of climate change: it is extremely complex. The models of global weather patterns contain scores of variables, and touch on subjects, such as the role of the deep oceans, about which even the leading researchers know very little. Only a very few specialists claim to be familiar with the data, and among those few there are surprisingly sharp disagreements as to what the data mean. When the experts disagree, there is all the more reason for amateurs to keep a respectful difference from the debate.
So why am I writing on the subject at all? Why rush in where angels fear to tread? Because I am convinced that in America today, the debate about climate change is primarily not a scientific question, but a political one.
Consider how many newspaper editorials have been written about climate change—by journalists no more familiar with the science than I am. Rather than allowing the scientists to settle their disputes in the proper way, by conducting careful experiments and publishing arguments in peer-reviewed journals, political leaders have leapt into the fray. Despite his own obvious lack of credentials, President Obama has denounced some participants in the scientific debate. Former Vice President Al Gore has set himself as an expert on the subject, jetting constantly around the world to scold people who consume fossil fuels.
The politicization of the debate has damaged the causes of scientific integrity and academic freedom. Learned professors whose research clashes with the prevailing orthodoxy complain that they have been denied research grants, ostracized by professional societies, and even exiled from their academic posts (tenured or not) because of their views.
Even those scientists whose views are safely within the accepted mainstream have remarked on the tight control that politicians seek to enforce on the discussion. Harvard’s Robert Stavins, who helped produce an important UN document on the topic, reported: “I was surprised by the degree to which governments felt free to recommend and sometimes insist on detailed changes to the [Summary for Policy Makers] text on purely political, as opposed to scientific bases.” Stavins explained that politicians wanted to fine-tune the scientists’ document to strengthen their political arguments.
(It is significant, by the way, that I only encountered a report about the Stavins complaint in a British tabloid, the Daily Mail. American media outlets, apparently influenced by the same political pressures that are operating on scientists, have generally avoided the debate and accepted the majority view.)
For a scientist who dares to contradict the views that are currently in fashion, the pressure can be “virtually unbearable.” That was the term used by Lennart Bengtsson, a Swedish researcher with impeccable credentials who left his post at the Global Warming Policy Foundation-- a group that had encouraged skepticism about policies designed to slow global warming—after receiving hundreds of angry and abusive messages from scientific colleagues.
Why would a scientist denounce a colleague, rather than test out his ideas? For that matter, why would scientists sign their names to petitions urging the public to ignore certain other scientists? These are political tactics, far removed from the scientific method.
When the most alarming predictions about climate change are called into question, the scientists (and politicians) advancing those predictions invariably claim that most researchers support their views. There are three problems with that argument:
- Most of the available research does apparently support the “majority” view. But since contrarian research is not funded, and contrarian theories not published, that fact may speak to the effectiveness of censorship rather than the solidity of a scientific consensus.
- Most of the scientists whose names are invoked in support of the climate-change consensus are not specialists in the field. They may be better able than I am to judge the validity of a hypothesis, but they are not qualified to say that the question is settled when experts still disagree.
- Scientific facts are not resolved by majority vote—not even if the vote is taken among qualified experts. The brilliant columnist Mark Steyn (who, incidentally, is the target of a punitive lawsuit because he dared to question a climate-change scholar) made the point:
Indeed, the very idea of scientists conducting scientific research to determine scientifically that 97 per cent of scientists agree on the science is itself a bizarre example thereof.
The climate-change debate is a game that is being played for the highest of stakes. If it is true that the consumption of carbon-based fuels is endangering the planet, then we must change our ways. But if it is not true, then the adoption of draconian rules to cut down energy consumption would cause devastating economic losses, with brutal consequences for the world’s poorest people, for no reason.
So it’s terribly important that we find the right answers to the scientific questions. Toward that end, it is all the more essential to ensure that scientists have free rein for legitimate research, with an absolute minimum of political interference.
And here a cautionary word should be directed at Church leaders as well. Too many Catholic officials have already jumped aboard the bandwagon, insisting that action to stop climate change is a moral imperative. There is, to be sure, a clear moral imperative to preserve the environment, to exercise faithful stewardship over our natural resources. But what are the practical, policy applications of that moral imperative? Let’s proceed with caution.
Nearly 500 years ago, powerful prelates leapt prematurely into another scientific debate, denouncing the work of Galileo, with consequences that burden the Catholic Church to this day. The problem at the time was not with Galileo’s scientific research, which the Church had sponsored, but with the determination to make scientific conclusions fit into a preconceived ideological framework. Let’s not repeat that mistake.

Last year, an excited Al Gore exclaimed to Jay Leno, "You can see Minot, North Dakota from outer space, Jay!" In looking up the official image on the NASA website, I discovered that it was obtained using very sophisticated optics and technology that beg the question if gas flares in Minot would be visible to the unaided eye at all. It underscores the frustration I have with the establishment and lost hope of ever finding out the real truth as to if and how much of this CC is caused by us.

I’m highly confident that the anthropogenic climate change crowd is pushing a political agenda masked as (junk) science. What is perhaps even junkier “science” is that of evolution. Sadly, it’s also had a more direct and deleterious effect to the faith.

Not long ago it was 'settled science' that gastric ulcers were caused by stress. Then it was discovered by some real scientists that they are caused by virus.

Well said, Phil. "Climate change" (or is it global warming) advocates seem to include a disproportionate number of politicians and clergy (of all denominations) for reasons that escape me. None are willing to list their scientific credentials, but all seem to agree that CC (or GW) is "settled science", whatever that is.

Thanks, Phil. You are right about the abuse of science in the claims about CO2 causing climate change. It doesn't take a climate expert to see that. The role of our bishops is to protect the poor. They should be denouncing these abuses and the attempts to remedy a nonexistent problem by limiting development. It's just the population control crowd keeping the world safe for limousine liberals. If bishops can't understand the issue enough to see the fallacies, then they should be quiet.

The problem with politics is that many Bishops have chosen politics over prayer. After all it sounds easier to take money from tax payers than to rely on God'S bounty. It is also possible that once you become political you will always be political. Pray for our Bishops.

Democracy in science makes about as much sense as democracy in religion, viz. none at all. What the champions of this politicized approach to science achieve is exactly the opposite of their desire: people like me find themselves turning an automatic deaf ear to everything they say. If I see any hint in a headline that it deals with climate change, I skip it. And if I see someone wearing a miter pontificating on the matter, I ignore him completely.

Thanks Phil for stepping into this debate. As to the early cause of scientific corruption, and the ensuing temptation to jump on the political bandwagon, do recall the prophetic warning by Eisenhower in his Farewell Address: "The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present – and is gravely to be regarded." As long as there is taxpayer money in science, all science becomes political.
