Skeptical Science on the “16 Years” nonsense

If you’ve been unfortunate enough recently to be in earshot of Fox News,  talk radio, seen a tattered copy of the once great Wall Street Journal, or even if you had an uncomfortable holiday dinner with Aunt Teabag and Uncle Dittohead, you probably have seen/heard the meme du jour in climate denial circles.

“There’s been no warming in 16 years.”

uhh, Deniers, Australia called and they’d like some clarification. But never mind.

John Cook and the Skeptical Science team have come up with a brilliant, and short, video response that should bring this conversation to a quick conclusion. Be sure to bookmark the post at skepsci.

The video above perfectly complements the “escalator” diagram that also effectively illustrates the art of cherry picking – see below.

  1. China might like to know too.

    Anyway this is a perfect example of what’s wrong with SkS’ warpath approach. Their argument is obviously flawed but they can’t won’t would die rather than listen anything or anybody who would explain it to them.

    So we’re left with 16 years of no warmING, perhaps 20 if the Met Office is right for once, but much effort is put into pretend analysis trying to demonstrate the opposite.


    1. How do you justify saying “16 years of no warming”?
      And explain the flaws in SkS’ reasoning – you have an audience right here.


    2. If the argument is so obviously flawed, it should be easy to point out what the flaw is. As this approach was taken by Foster and Rahmstorf 2011, to remove the natural fluctuations.

      So is the obvious flaw in Foster’s and Rahmstorf’s approach, SkS’s application of the approach, or is it you just don’t like what the analysis reveals?

      Saying something is flawed without being able to show where the flaw is, is not very convincing.


      1. John – if I posted about “John Silvester thinks cows can fly” without you ever having said so, my argument would look obviously flawed to you too.

        Furthermore, once anybody states that 16 years are not long enough, any further discussion should start from “how long is long enough” and “how short is meaningful enough”, not a graph saying “look if I take it this long I can come up with a warming signal”.

        IOW if not 16 why 160 and not 1600 or 16000/


        1. omnologos

          Flying cows and pigs for that matter is not relevent to this discusion. However, if someone were to make that statment I think it would be quite easy to show the flaw in such a statement.

          So please tell me what what the flaw is with the argument presented in this post.

          The post argues that 16 years is too short to meet some statistical significance level. So what is the flaw with this argument.

          As to how long is long enough, 30 yrs, as we are discussing climate, not weather.


          1. I shall repeat myself

            1. Nobody I know has ever made what the SkS video says it’s the way skeptics see global warming. So the claim that the video shows the way skeptics see global warming, is a fake claim

            2. Cook doesn’t make the case for 30 years. Why not? Because even 30 years might not mean much. Say, if temps baselined even for 50 years, still we could build a graph starting in the 1850s and clearly showing global warming.

            I am afraid as long as the focus is on how to demonstrate global warming instead of how to falsify it, we will always run into baseless arguments that cannot be logically answered to, just as the arbitrary choices made by SkS for their graphs can’t. I


    3. Yes, I can understand why omnologos would hate an approach that uses statistical analysis and simple language to explain why denier arguments are wrong.

      So we’re left with 16 years of continued global warming, but much effort is put into denying reality and pretending the opposite.


      1. The “how skeptics view” section is completely fabricated. I cannot remember any skeptic making such an argument, and in any case there is no organization of skeptics to whom to attribute views. The video, in this respect, is a lie, compounded by the simple truth that even the stones know by now graphs and their meanings depend on starting points and how data is averaged.

        —-

        There has been no statistically significant increase in world temps for 16 years. That’s a fact. The Met Office doesn’t expect any such increase for at least 4 years. That’s another fact.

        You can always and very democratically argue that 16 years isn’t enough, or that warming will resume later, or that this stuff happens, or whatever else. But to change a fact into “nonsense”, that’s a denial outright.


        1. There has never been a 16 year period of statistically significant warming since records began. There can’t be. Statistical significance cannot be achieved over such a time given the existence of short-term variables, mostly due to the influence of ocean currents. The value of the mantra which you repeat lies only in the fact that most people don’t know what it means – or, to be more precise, what it doesn’t mean.


        2. “There has been no statistically significant increase in world temps for 16 years. That’s a fact”

          No, your statement is almost certainly complete and utter bullshit. There are at least two years within the past 16 years which show significant world-wide temperature increases from the previous year.

          There are plenty more years which would show a statistically significant increase if one decided to cherry pick a LOW year (instead of a high year) as the baseline year.

          Your statement is only true if you restate it as “There has been no statistically significant increase in world temperatures over a particular 16 year period – ie, the one starting in 1996 (or whatever is the high anomaly year that was used to generate such a deliberately deceptive statement).

          You really need to state your deliberately disingenuous disinformational statements more carefully, omnologos. People will start to talk.


          1. Roger – thanks for making my point. Choose your start and end point, and you can say what you want. The SkS video is rubbish. My statement is a fact, just as it’s a fact that global warming is evident from the mid XIX century to today.


    4. Sounds like the sort of thing an infallible Pope would say.

      Funny, Phil Jones and the Met Office were “crooks and liars” during the “Climategate” faux-scandal debacle. Now they are the sole repository of absolute truth.


    5. This is a reply to your comment further down about New Scientist joining the nonsense crowd although you didn’t bother to explain what that meant.

      Perhaps you didn’t read Fred Pearce’s Aug 2008 article “Climate Change: The Next Ten Years” – see alternate link below.

      If you had, it would have been clear to you that scientific discussion on this have been going on for years – I’m speaking about practising, dedicated climate scientists arguing about what the impact of complex cycles might be.

  2. Thanks for the repost, Peter.

    Kevin C deserves the credit for this video – he conceived it, wrote it (with lots of SkS review feedback from the other SkS authors) and Daniel Bailey did a great job with the voice over.


          1. WAY OFF TOPIC

            Re: “I first saw those images of the Syrian refugee camp a few hours ago on TV.”

            Really? Which channel?

            Re: “War is Hell.”

            I take a more cynical view. War is a racket.

            The Ba’ath Party of Syria was a reasonably benign answer to the disparate sects, cults, religions and other interests in Syria. Alas, the Ba’ath Party was one of the last parties on the Left that held itself apart from the neo-colonial aspirations of the elite planners in Wall Street, the City of London, Washington and Paris (the old colonial master of Syria). So the attack on Syria’s stability was inevitable as the capitalist juggernaut continues to roll across the planet replacing the old Orwellian vision of the future being a jackboot on the face of humanity with something far more sinister. Now the jackboot has been replaced with surrogate fundamentalist jihadi marauders working on behalf of their capitalist masters creating mayhem out of decent societies for sake of profit and power for the financial elite. Sacramento, Springfield and Surrey should take note. What the elites are doing to Syria is what the elites intend to do everywhere that any shred of decency and democracy remains.


  3. I have just learned from James Hansen that instead of “pause” we should use “standstill”. Can’t imagine the scrambling at SkS to show that the two words are really really dissimilar.
