Consensus on Global Warming

FredFnord writes "Well, here's an interesting one: the fine folks at Science Magazine have done an analysis of the last ten years' published scientific articles (articles from crank or non-peer-reviewed publications were not counted) on the subject of global climate change. The results themselves are interesting, but the most remarkable part was that, of the 928 papers they found, 75% accepted that global warming was caused by human activities, either explicitly or implicitly. 25% made no mention either way. And not a single paper asserted otherwise." JamesBell submits this article by a geologist which suggests that the Earth is in serious, imminent, unavoidable danger.

Soon, it will be China and India that you're pointing fingers at, and not the US (or Europe).[1]

So... Then what?

And uh, is this news? Does anyone credible seriously disagree that emissions from human activity are at least in part contributing factors? Or is this another jab at boogiemen that don't exist? There's nothing "remarkable" about these so-called findings.

Also, the "Earth" isn't in danger. Yes, I know this distinction is splitting hairs, but what's in danger is Earth's inhabitants. Our actions are not going to alter a several billion year old rock.

[1] Don't feed me the per capita shit. China will be a far, far greater polluter in this realm, per capita or no. Further, the economic empowerment of the Chinese people will eventually drive them to a level of concern about the well-being of the environment, so, in a way, their accelerated economic development is a good thing, politically and environmentally. Incidentally, China has proven they can reduce greenhouse emissions, even while growing economically (1, 2)...but the point is, they're still on an upward trend. And they've got a lot more people who will begin to thirst for energy-hungry luxuries.

What I get out of this is "We dont know what it means, but it looks like at least SOME climate changes are caused by man".

and SOME studies suggest that cigarettes cause health problems.

some.

So what's the news here? by Alwin+Henseler · 2004-12-07 10:22 · Score: 5, Insightful

From the article summary: ".. of the 928 papers they found, 75% accepted that global warming was caused by human activities, either explicitly or implicitly. 25% made no mention either way. And not a single paper asserted otherwise."
Just because everybody is saying it, doesn't make it true.
But okay, I'm the last person to deny global warming is upon us. Other than some US folks still not convinced or thinking it's not that big a problem (or simply putting their head in the sand), global warming is observed, and the only question is about how much of it is the result of human activities, and how much by natural causes. Oh yeah, and what to do about it.
For the rest: nothing to see here.

"...and then consume that output." Funny how those who are so eager to "correct" this mistake never notice their own.

Seems a far more common and far more damaging oversight, eh? In fact, it's so common that one would almost think that this oversight is a deliberate untruth propogated for rhetorical purpose.

It is still surprising to me that only 1 in 4 bothered to include alternative polution sources...

Because they're professional geologists, so that goes without saying? These are peer-reviewed scientific journals, not introductory textbooks. If a physician writes an article claiming some chemical causes cancer, is he going to also mention everything else causes cancer? Is he going to mention the sun also causes cancer? Of course not, because he most likely is not a complete and utter moron, and he assumes his readers aren't either.

Find me a single geologist anywhere who has ever publicly stated that anthropogenic sources are the only things that cause global climate change.

This made me think of Michael Crichton's Aliens Cause Global Warming" speech, which is actually quite apropos since he took on the idea of scientific "consensus:"
In addition, let me remind you that the track record of the consensus is nothing to be proud of. Let's review a few cases.

In past centuries, the greatest killer of women was fever following childbirth . One woman in six died of this fever. In 1795, Alexander Gordon of Aberdeen suggested that the fevers were infectious processes, and he was able to cure them. The consensus said no. In 1843, Oliver Wendell Holmes claimed puerperal fever was contagious, and presented compelling evidence. The consensus said no. In 1849, Semmelweiss demonstrated that sanitary techniques virtually eliminated puerperal fever in hospitals under his management. The consensus said he was a Jew, ignored him, and dismissed him from his post. There was in fact no agreement on puerperal fever until the start of the twentieth century. Thus the consensus took one hundred and twenty five years to arrive at the right conclusion despite the efforts of the prominent "skeptics" around the world, skeptics who were demeaned and ignored. And despite the constant ongoing deaths of women.

There is no shortage of other examples. In the 1920s in America, tens of thousands of people, mostly poor, were dying of a disease called pellagra. The consensus of scientists said it was infectious, and what was necessary was to find the "pellagra germ." The US government asked a brilliant young investigator, Dr. Joseph Goldberger, to find the cause. Goldberger concluded that diet was the crucial factor. The consensus remained wedded to the germ theory. Goldberger demonstrated that he could induce the disease through diet. He demonstrated that the disease was not infectious by injecting the blood of a pellagra patient into himself, and his assistant. They and other volunteers swabbed their noses with swabs from pellagra patients, and swallowed capsules containing scabs from pellagra rashes in what were called "Goldberger's filth parties." Nobody contracted pellagra. The consensus continued to disagree with him. There was, in addition, a social factor-southern States disliked the idea of poor diet as the cause, because it meant that social reform was required. They continued to deny it until the 1920s. Result-despite a twentieth century epidemic, the consensus took years to see the light.

Probably every schoolchild notices that South America and Africa seem to fit together rather snugly, and Alfred Wegener proposed, in 1912, that the continents had in fact drifted apart. The consensus sneered at continental drift for fifty years. The theory was most vigorously denied by the great names of geology-until 1961, when it began to seem as if the sea floors were spreading. The result: it took the consensus fifty years to acknowledge what any schoolchild sees.

And shall we go on? The examples can be multiplied endlessly. Jenner and smallpox, Pasteur and germ theory. Saccharine, margarine, repressed memory, fiber and colon cancer, hormone replacement therapy. The list of consensus errors goes on and on. Finally, I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.
