Climate Change: 97% of Scientists Don’t Agree

Written by Robert Murphy on May 30, 2014

If you have the temerity to challenge calls for the government to take aggressive action to reduce carbon dioxide emissions, you will probably have someone call you a “climate science denier.” You will further be lectured that “97% of climate scientists agree” on this consensus.

But there’s a bait-and-switch going on here, as Joseph Bast and Dr. Roy Spencer explain in the WSJ. Or, you can read David Friedman’s take-down here, which I think spells out the matter very simply.

What’s the source of this bogus stat? Cook et al. (2013) is a paper which claims to do the following:

We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11,944 climate abstracts from 1991–2011 matching the topics ‘global climate change’ or ‘global warming’. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming… Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research. [Bold added.]

To repeat, there’s a bait-and-switch occurring here. As Friedman spells out in a very straightforward way, all you need to do is actually look at Cook et al.’s own tables in their paper to see that others (including Cook himself in a subsequent paper!) are misrepresenting their findings. Only 1.6% of the surveyed abstracts clearly say that humans are the main cause of global warming. The 97.1% figure includes papers that merely claim that some amount of warming can be attributed to human activities.

    How did 'climate change scientists' become 'egg-spurts' ? http://www.goodreads.com/book/show/494799._Dumbth

  2. Rev Ruyle says:

    Dang! Leftists lying? You have to know that I'm shocked to discover that! (not really… that was a tongue in cheek comment)

  3. Real American says:

    First, they become liberals, then they become eggheads, then they magically become egg-spurts. Politweasels do it all the time. They lie their butts off and win a local popularity contest back home, go to the District of Criminals, and abracadabra, they're experts on everything. That entitles them to rule us peons for as long as they can get re-elected. What every politweasel wants is another term, and another, and another…

    Taking a clue from the Police Chief in Movie Casablanca:__"I'm shocked, just shocked to find that there is lying by Liberals going on in this debate"

    Let's not get caught up in the bait and switch that is going on. What the left started out calling global warming is now being called climate change. Scientists do not disagree with climate changes on our planet, but they do disagree with the man-made, man-induced, global warming hysteria as well as the cry that CO2 is detrimental to our environment, initially pushed by the libturds. Any real scientist knows that CO2 is not only a minimal gas in our air, but is essential to all life on the planet, as part of the CO2/O2 cycle. Believing that CO2 is a bad gas is like believing that guns (not people) kill people!

  6. I understand – and would welcome confirmation – that anthropogenic climate change is totally negated by the fact that the fraction of 'global warming' gases that is man-made is less than 1% of the naturally-occurring total.

    Any comments?

  7. "No, no, you puny human race have more impact on climate change than the Sun or the Earth's elliptical orbit! You must believe! We really</n> need you to pay that carbon tax$$$$$!"

  8. Climate change? Only deniers are arguing for a supposed Global Cooling.

  9. Hallelujah! Yes Lawd!

    My calculation shows that an increase of 100 ppm of CO2 in the atmosphere will increase its thermal absorption by one-eighth of one percent – i.e., it is less than negligible.

    Global warming is easy to understand. It is a fraud. See, easy.

  12. I completely accept that there is an "industry" surrounding "climate change" that does very nicely by spinning the global-warming story. A lot of them are in it for themselves.

    But I don't agree this is a left-right issue – I'm a conservative who does think that our behaviour is aggravating the global-warming situation.

    That doesn't mean there is an excuse to tax everyone and everything to the hilt – but it's not as simple as saying that it's a conservative v liberal issue.

  13. This is all about money it's that simple. Look into Al Gore and why he Needs there to be Global warming oops climate change, sorry wrong again climate disruption. These boobs can't even justify their own stats so they have to keep changing the name of their cause.

  14. Wrong again Gil. Everyone knows that sooner or later there will be another Ice Age, the planet has had plenty of them. We can just be thankful we are living our lives when there isn't one.

  15. allosaur says:

    How does a scientist receive his PC government funding? Oops, I gave it away!

  16. Apparently economists do it too.

  17. My calculation shows you're a fraud and can't do science properly.

  18. Considering we've had more CO2 pumped into the air in the industrial age than we've ever had in the history of humanity, yes, we are the main cause of CO2 in the atmosphere – which increases the heat retention of the planet, which changes weather patterns and melts ice, which changes the climate – making us the main driver for climate change. It's not that hard to figure out.

  19. There's also an "industry" that promotes the burning of fossil fuels that has been around far longer than any "climate change industry" and has far more money to throw around to push its own agenda.

    Which is harder to believe: that a few people are spending a lot of money to buy politicians to continue to further their own monetary and political interests, or that hundreds and thousands of independent scientists have reached the same conclusions about climate change – that people are the main cause and we've already caused irreparable damage, and that we should mitigate further damage?

  20. Yeah, it's all about the fossil fuel industry's money.

    Lawyer statistics always lie or are twisted beyond belief. A good statistician can make the answers to the questions bend to whatever his/her belief is. Just looking at what is in the article, 66.4% say there is no change to the climated due to man. I look at the vidios of China and see that there is personal damage being done to the citizens, but, the earth will adapt. Volcanos still put out more crap into the air than mankind ever has.

    Here comes the inevitable commie freak calling me names; I have MS and PhD degrees in Engineering from UCLA, with specialties in Heat & Mass Transfer and in Thermodynamics, and my IQ was measured at 165. Therefore I am qualified to call you, comrade commie, an utter POS!

  23. There has been climate change ever since the world was created. The climate is constantly warming or cooling. To think that humans have any significant impact on the rate or degree of change is absolutely ludicrous.
