Via Stephen Hayward at Planet Gore comes word of another scientist off the “consensus” reservation. According to David Evans (who, according to his bio, is a genuine rocket scientist – sweeeet…), “… in 1999 the evidence that carbon emissions caused global warming seemed pretty conclusive, but since then new evidence has weakened the case that carbon emissions are the main cause. I am now skeptical. As Lord Keynes famously said, ‘When the facts change, I change my mind. What do you do, sir?'”

Evans does a great job of laying out why the science on the issue of climate change is not settled, and also notes the potential dangers of the current “consensus”:

The evidence is not currently conclusive either for or against any particular cause of global warming. I think that it *is* possible that carbon emissions are the dominant cause of global warming, but in light of the weakening evidence I judge that probability to be about 20% rather than almost 90% as estimated by the IPCC.

I worry that politics could seriously distort the science. Suppose that carbon taxes are widely enacted, but that the rate of global warming increase starts to decline by 2015. The political system might be under pressure to repay the taxes, so it might in turn put a lot of pressure on scientists to provide justifications for the taxes. Or the political system might reject the taxes and blame science for misinforming it, which could be a terrible outcome for science because the political system is powerful and not constrained by truth.

Some people take strong rhetorical positions on global warming. But the cause of global warming is not just another political issue that is subject to endless debate and distortions. The cause of global warming is an issue that falls into the realm of science, because it is falsifiable. No amount of human posturing will affect what the cause is. The cause just physically is there, and after sufficient research and time we will know what it is.

Perhaps the best thing about this post is that it comes as part of a civil, rational debate about the merits of climate science, something that is sorely lacking in the current highly politicized climate. This sort of exchange is an encouraging sign that rationality may win out over hysteria in the end.

This week in the PowerBlog’s Global Warming Consensus Watch: A final pass at the Sheryl Crow/Toilet Paper controversy, just to ensure that the issue is wiped clean; The fight against climate change goes to 11; Global warming causes everything, and we’ve got professional athletes to prove it; and finally, what – if anything – are those carbon offsets offsetting? (more…)

An entire nation breathes a sigh of relief today, as Sheryl Crow has claimed that her proposal to restrict toilet paper usage to one square per restroom visit was a joke, as this blogger suspected. Unfortunately, Crow had no further comment on the status of her “dining sleeve” device.

You can count on the PowerBlog to bring you the latest news and updates on this important story as they occur.

More: Iain Murray at Planet Gore notes that all things considered, it was relatively easy to take Crow’s ludicrous suggestion seriously:

The reaction to it should tell her something about the environmental movement. People thought it was a serious suggestion because they are used to hearing equally ludicrous things coming from environmentalists. Even The Daily Show took her at face value last night. Until green environmentalists square the circle of modern life with their concerns about it and their proposed statist solutions, they’re going to face exactly the same problem.

Welcome to the first edition of the PowerBlog’s new GLOBAL WARMING CONSENSUS WATCH, where we keep you up-to-date on the latest news about the ever-strengthening, nearly invincible consensus that climate change is 1) unnatural and 2) a massive catastrophe waiting to happen.

  • Another scientist off the reservation: Somebody has to start doing something about all these “scientists” who openly question the unshakable, indisputable consensus on global warming. Like this guy, for instance. What in the world could he be talking about here?
    Spencer contends there is not yet enough known about the Earth’s atmosphere to understand exactly what occurs naturally to stabilize the earth’s climate.

    “I don’t think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don’t know for sure how it happens…”

    Nonsense. Didn’t he see Al Gore’s movie?

  • Thank you sir, may I have another? Why certainly. Here’s Dr. Timothy Ball, a retired Canadian climatologist, on those climate models we hear so much about:
    As I have said for years, climate models are a useful but severely limited tool in the laboratory that must meet scientific responsibilities. Unfortunately, they are clearly not doing this, which is why we need an independent audit.

    When you go public and allow the output of the models to become the basis of global, national and regional policy there is a different set of responsibilities and these are definitely not being met.

    Worse, they are deliberately being manipulated and misused.

  • Balance = Bias: The potential catastrophe of global warming is too important to allow dissent on the issue in the media, according to Al Gore. And the major media seems to agree:
    Al Gore has complained that the media are biased against the inconvenient truth of global warming. “I believe that is one of the principal reasons why political leaders around the world have not yet taken action,” Gore told a “Media Ethics Summit” at Middle Tennessee State University back in February. Gore lectured journalists that any coverage of views opposed to his own was irresponsible, calling it “balance as bias.”

    It’s impossible to imagine the big TV networks actually accepting an edict from a conservative politician to report only their side of a major public policy issue, but a new Media Research Center study of ABC, CBS and NBC’s global warming coverage finds the networks are giving Gore practically everything he demanded. Not only does nearly every global warming story exclude any contrary voices, but the coverage of Al Gore personally has been exceptionally positive as well.

    It’s amusing to think that Gore could claim that his position on global warming hasn’t gotten a fair shake in the big media without being laughed out of the room. I think it’s much more in line with reality to say that the reason Al Gore even has a career these days is because the media has long ignored his calls to rid the world of the internal combustion engine or the fact that one can barely tell the difference between Gore’s environmentalism and the Unabomber’s (I scored a 25% on that quiz, by the way – you’re invited to drop your score into the comments).

  • The First Cut Is the Deepest: Noted environmental expert Sheryl Crow (who has a career as a recording artist on the side) used to like to soak up the sun. But she’s changed her ways, and what she sees now is not a pretty picture. The consensus on global warming is strong enough that she’s ready to advise us all to make some cuts – and it’s true when they say that the first cut is the deepest:
    Singer Sheryl Crow has said a ban on using too much toilet paper should be introduced to help the environment.

    Crow has suggested using “only one square per restroom visit, except, of course, on those pesky occasions where two to three could be required”…

    …”I have spent the better part of this tour trying to come up with easy ways for us all to become a part of the solution to global warming,” Crow wrote.

    “Although my ideas are in the earliest stages of development, they are, in my mind, worth investigating.

    “I propose a limitation be put on how many squares of toilet paper can be used in any one sitting.”

    Now come on – this has to be a joke, right? No serious person would propose restrictions on how much toilet paper a person can use, right? It would be an understatement to say that this idea is “in the earliest stage of development.” For one thing, has she come up with a workable enforcement mechanism? The mind boggles. But this is a BBC article, not The Onion, so it at least has the faint odor of plausibility (no pun intended).

    On the other hand, the article also includes this tidbit:

    Crow has also commented on her website about how she thinks paper napkins “represent the height of wastefulness”.

    She has designed a clothing line with what she calls a “dining sleeve”.

    The sleeve is detachable and can be replaced with another “dining sleeve” after the diner has used it to wipe his or her mouth.

    OK, there’s no way this is real. Unless somebody can point out to me evidence that Crow (or any other Hollywood celebrity) is actually using the “dining sleeve,” I’m just going to write this whole article off as a parody. After all, even climate change is trumped by vanity and hypocrisy in Tinseltown.
