Global Warming: Not Man Made

In 2004, history professor Naomi Oreskes performed a survey of research papers on climate change. Examining peer-reviewed papers published on the ISI Web of Science database from 1993 to 2003, she found a majority supported the "consensus view," defined as humans were having at least some effect on global climate change.

[...]

Medical researcher Dr. Klaus-Martin Schulte recently updated this research. Using the same database and search terms as Oreskes, he examined all papers published from 2004 to February 2007.

[...]

Of 528 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers "implicit" endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis. This is no "consensus."

The figures are even more shocking when one remembers the watered-down definition of consensus here. Not only does it not require supporting that man is the "primary" cause of warming, but it doesn't require any belief or support for "catastrophic" global warming. In fact of all papers published in this period (2004 to February 2007), only a single one makes any reference to climate change leading to catastrophic results.

[...]

Schulte's survey contradicts the United Nation IPCC's Fourth Assessment Report (2007), which gave a figure of "90% likely" man was having an impact on world temperatures. But does the IPCC represent a consensus view of world scientists? Despite media claims of "thousands of scientists" involved in the report, the actual text is written by a much smaller number of "lead authors." The introductory "Summary for Policymakers" -- the only portion usually quoted in the media -- is written not by scientists at all, but by politicians, and approved, word-by-word, by political representatives from member nations. By IPCC policy, the individual report chapters -- the only text actually written by scientists -- are edited to "ensure compliance" with the summary, which is typically published months before the actual report itself.

By contrast, the ISI Web of Science database covers 8,700 journals and publications, including every leading scientific journal in the world.

Yeah, I've heard of this as well. Man-made or not, the climate is changing and either we do something to stop it or change our behaviour to take it into account.

not man-made but man-aided

yes we have an impact, however small ... you can't destroy (and not replace) millions of acres of forest and not add to the amount of greenhouse gasses in the atmosphere

probably to the ratio of 90.0 - 99.9% natural process to 0.1 - 10.0% man-aided

(in my psuedo-expert-environmental-science-teacher opinion)

even if we only aid the process by a smidgen or fraction of % points, we need to adapt our ways to at least stop that part of the process and also adapt to the overall

the ocean current changes scare me as those do have a tendency to change the climate quicker than it normally would

Gore missed on some points but he actually had some science involved in some others

Global warming is caused by a secret cabal of Ninja Pirates. Al Gore is the secret head of this cabal and when he is not making movies or giving speeches he is sailing the seven seas on the Queen Anne's Revenge, plundering oil tankers and assassinating whales.

All those studies show is the dramatic impact that politics had on science. The reason so few scientists stated that global warming was human caused was simply because they knew their careers would end if they did. It's scientific McCarthyism.

Too bad those researchers weren't insightful enough to understand their own data. I wish I could say it was rare. Then again they probably had a spin agenda.

yeah what was the line in inconvenient truth about [paraphrase] "hard to understand something when their salaries depend on them not understanding it" [/paraphrase]

Word play is fun. Scientific papers generally don't have to explicitly support something which is already accepted. For example, papers on astrophysics don't have to mention the author's acceptance of the theory of gravity, as it can be assumed. If you realize that and change your wording slightly, your same study comes up with only 6% of papers rejecting man-made global warming.

It also doesn't specify what papers are being talked about. What are the subjects here? What is he defining as "papers on climate change"? You could easily have dozens talking about, say, the levels of ice in the arctic that would never refer to the cause of global warming, just its effects. Also:

Forgive me if I'll take the word of climatologists over that of someone who has zero training in the field.

I don't know why it is surprising that most papers exploring climate change do not comment on the contribution of human activity. Good research is usually quite focussed in the questions it asks, and I imagine many studies are focussed on researching the manner of climate change or its effects. Even studies looking at causes are more likely to concentrate on immediate, proximate causes of this or that observation rather than more complicated whole-system causes.

If the point is that politics is playing a large role in the debate, that doesn't seem particularly insightful.

That the one researcher is in the medical field is not actually terribly unusual. Such inidividuals are often highly experienced in meta-analysis as it is a customary research methodology in that field. Its much less common in other fields.

Yes, that's certainly another factor. Given that the studies were published in a pro-energy journal, one by a historian and one by a medical researcher, I think it's safe to assume they are grossly biased and all mistakes we've cited are quite purposeful.

Propoganda takes many forms. Too bad the media are so easily suckered by it.

goddamn, and here I thought I was the conspiracy freak. You think everything is biased and untrue unless its some source you deem worthy. Wtf, man :roll:

And you see how quickly they turn their eyes back to the "research!" That damn ninja-pirate is plundering oil ships and getting booty on the high seas right now, probably in multiple sense of the word "booty!"


... I should murdar him and usurp the position... booty sounds pretty nice.

Yes, and that was addressed. With implicit acceptance, only 45% of papers in the last 3 years accept global warming as man made/aided/whatever. 48% explicitly neither accepted nor denied it. The point of the article is that not all scientists accept global warming as at least partially humanity's fault as many people are currently claiming (and I've seen that claim posted here a number of times). In fact, less than half of publish scientists in the last 3 years have.

Personally, I can't see how it can't be at least some of our fault, and quite possibly most of our fault, but I'm not a published scientist, and I'm guessing no-one here is, no matter how many lawyer teachers here think they are... ;) :P

Have you guys forgotten how much Big Money there is in denying global warming?
Since the late 1980s, this well-coordinated, well-funded campaign by contrarian scientists, free-market think tanks and industry has created a paralyzing fog of doubt around climate change. Through advertisements, op-eds, lobbying and media attention, greenhouse doubters (they hate being called deniers) argued first that the world is not warming; measurements indicating otherwise are flawed, they said. Then they claimed that any warming is natural, not caused by human activities. Now they contend that the looming warming will be minuscule and harmless. "They patterned what they did after the tobacco industry," says former senator Tim Wirth, who spearheaded environmental issues as an under secretary of State in the Clinton administration. "Both figured, sow enough doubt, call the science uncertain and in dispute. That's had a huge impact on both the public and Congress."
Groups that opposed greenhouse curbs ramped up. They "settled on the 'science isn't there' argument because they didn't believe they'd be able to convince the public to do nothing if climate change were real," says David Goldston, who served as Republican chief of staff for the House of Representatives science committee until 2006. Industry found a friend in Patrick Michaels, a climatologist at the University of Virginia who keeps a small farm where he raises prize-winning pumpkins and whose favorite weather, he once told a reporter, is "anything severe." Michaels had written several popular articles on climate change, including an op-ed in The Washington Post in 1989 warning of "apocalyptic environmentalism," which he called "the most popular new religion to come along since Marxism." The coal industry's Western Fuels Association paid Michaels to produce a newsletter called World Climate Report, which has regularly trashed mainstream climate science. (At a 1995 hearing in Minnesota on coal-fired power plants, Michaels admitted that he received more than $165,000 from industry; he now declines to comment on his industry funding, asking, "What is this, a hatchet job?")
Etc., etc.

Anybody still duped by this noise wants to be duped.

Yeah. And only 6% rejected it.

So what's the point, again?

This is basically a non-story overall. Just more bullshit from the anti-science crowd.
