Pielke train wreck

If you haven’t been watching the Roger Pielke Jr train come off the rails and the carriages smashing into each other and exploding, I suggest you look at this post from James Annan:

Roger Pielke has been saying some truly bizarre and nonsensical things recently. The pick of the bunch IMO is this post. The underlying question is: Are the models consistent with the observations over the last 8 years?

Hey, hypothesis testing. First year stats stuff. So Annan carefully explains how it’s done.

Marvel at Pielke Jr’s response:


All he does is draw some graphs and wave his hands around. Does he calculate the probability of getting such a result if the null is true? Hell no.

Annan does the work for him:

Even if the null hypothesis was true, there would be about a 21% probability of observing data this “extreme”. There’s nothing remotely unusual about it.

And that’s using Pielke Jr’s cherry picked starting point …

Update: More carriages exploding here.

    This is the misconception at the heart of your whole argument here, I think. Temperature INCREASE does not depend exactly on the amount of CO2 that was PREVIOUSLY added, other than warming “in the pipeline.” Short-term temperature INCREASE depends exactly on the amount of CO2 that is CURRENTLY being added.

    The whole theory behind your bet is based on a mistake.

    This was also addressed by Phoca at #49 when he used ENSO as an example……so let’s use ENSO.

    An ENSO event can be expected to affect different locations differently ie: heavy rains and flooding in Peru, severe droughts in Indonesia and parts of Australia….all depending on the variables local to that area…..altitude,latitude,proximity to large bodies of water or mountains etc…

    Also,climate zones are sometimes described by plant hardiness….here on the east coast, alongside Long Island Sound, the Sound acts to cool the coast in the summer and warm it in the winter…..the plant zone changes from the coastline to about 7 miles inland……is this not local climate?

    So in a sense….isn’t all climate local?

    Levenson: “Temperature INCREASE does not depend exactly on the amount of CO2 that was PREVIOUSLY added, other than warming “in the pipeline.” ”

    You are wrong Levenson. First of all, I’m not talking about what was added. I’m talking about the measureable increase that we can see in the atmosphere. And we have seen a consistent measurable increase in the atmosphere for the entire ten years that we have had no warming. The rate of increase was as large or larger than the previous 20 year rate where we saw a significant amount of warming. The greenhouse gas effect is not dependent upon when the greenhouse gas level was raised in the atmosphere; it only cares about how much of it is there. Take for example the number that you cultists like to use for CO2 doubling of 3C per doubling. You are going to get that 3C if you increase the CO2 as a pulse immediately, if you increase it gradually over time period x or if you increase it at the end of time period x. When you do the increase will effect when you get the 3C. And there will be some delay, but regardless, you will get the 3C – all other things being equal.

    So, for the ten years that we have had no warming, the CO2 has continued to increase, and it has therefore changed the radiation balance of the earth. This is all warmer theory by the way. That CO2 for the last ten years is in the atmosphere now, reflecting heat back to the earth now, and requiring that the earth get hotter to balance the equation now. If we do not see that increase, it can only be because it is temporarily masked by other natural climate events. But once that masking is removed or reversed, then all of the CO2 effect must be seen. If you don’t understand that Levenson, then you don’t understand the greenhouse theory that you claim to subscribe to.

    But taking things one step further, you theory has a bit of a problem. There has been no warming for 10 years. CO2 has continued up for 10 years. You now have to have some other natural climate events to mask the increase that should have happened for those 10 years. What is that natural climate event. It wasn’t PDO. It wasn’t a large number of volcanoes. Solar cycle 23 was smaller than 21 and 22, but it was still larger than the majority of the solar cycles.

    So, while explaining away 10 years of no temp increase as being due to natural variablility is not a problem, explaining just exactly what that natural variablily was is a big problem, because there doesn’t seem to be any.

    Well Boris, it seems that your are too dumb to even realize that you are on the loosing streak. You haven’t had any temp increase for ten years. Considering that your hand requires .2C increase over that period to win, you have lost. And it is you that is claiming “natural variation”.

    How long did you have to practice to be such a dumb ass Chris. When drongo says that the mean is 3.4C per century, he is obviously saying that the mean for a 30 year period would then be .3 X 3.4, or 1.02C. Meaning than Annan is getting a very nice edge if he only has to show .6C to win.

    The beauty is, that after increased C02 hasn’t increased the warming of the planet for the past 10 years, they still come back saying that their losing streak is “natural variation” and they’re just about to recover from the little bad luck age.

    So, Betula, do you deny that our planet’s climate is noisy and variable?

    If not, why do you think adding additional CO2 to the atmosphere would end that variability?

    Which climate scientist has ever said that increasing CO2 concentrations from 280 ppm to 380 ppm will cause the natural variability of climate to stop? That it will cause ENSO to stop? That there will be no more La Niñas, no more El Niños?

    Do you understand just how stupid your comment is? Or do you need us to spell it out in more specific terms?

    When the next El Niño inevitably shows up, are you going to remember that you don’t believe in the noisiness and variability of the global climate system? Or are you going to suddenly switch allegiance and say “oh, look, global warming plays no role, El Niño is natural” after sitting here denying the importance of the ENSO effect on the cherry-picked 10-year period that just happens to start in the year of one of the strongest El Niño’s in history?

    Climate science doesn’t resemble your strawman characterization, any more than evolutionary biologist resembles the strawman characterizations “proven false” by creationists. If you’re going to overturn climate science, you’re going to have to understand the field, first.

  19. #19 Chris Colose

    Tilo, for one so confident in challenging climate scientists, you are quite ignorant on this subject. For one thing, you should know very well that 10 years of temperature is far too short a time interval to look at given the signal-to-noise ratio. Your cherry pick fest is not impressive. Even if there was warming or cooling over the last 10 years (in fact, a best fit line does give slight warming) it could all be simply due to chance. What’s more, the projection of 0.2 C/decade does not mean that every subset of 10 years necessarily warms by 0.2 C.
    While you claim to believe that CO2 is not the only thing that effects climate, and claim to be well aware that no one else believes that, your implications are that it IS the only thing that influences climate.

    Next, the greenhouse effect does not work by “reflecting” heat. This is a rather elementary concept.

    You are right that the ~3 C of warming will eventually be realized, but it does not need to be realized in nice linear steps. In fact, this is the idea behind the latest Keenlyside et al paper– if it turns out right, warming will occur in staircases, since it made no implications for climate sensitivity. It will take many decades to reach 560 ppmv (the “first” doubling) and still more time for equilibrium. Now we will need to get warming over the next 15-20 years to maintain confidence in the IPCC projections, but I really don’t think you understand any of this.

  23. #23 mz
    May 17, 2008

    Heh.
    There are two reasons why Tilo’s bet is wrong.

    The first one:
    James predicts 0.2 C per decade. Plus minus something. Tilo takes this as the center and would have James win only if it’s more than 0.2 and Tilo win if it’s 0.19 for example. So only 0.5 for James if James is 100% correct.

    This is clearly not demonstrating how much James is believing in the 0.2 C (plus minus some of course). For example, if we assume James believed he is 90% certain and Tilo has 10% correct, then James’ odds would be only 45%. Only a fool would bet then.

    0.1 C per decade would be a better example (if not for reason #2). Then James would have perhaps 80% chance (haven’t checked the distribution that lies to the right of 0.1 C) and Tilo would have whatever he believes.

    The second one:
    Including some flattish years from the beginning which, when taking into account the natural variability of the global temperature, lower the odds that a 20 year trend including these 8 first years would be the same as the long term trend. It’s all about window positioning which affects your results when you’re trying to predict a trend in a noisy signal.
    Just look at this:

    Well, at least he shows a nice graph with a 30-year slope of just 0,166 K / decade.

    May I suggest the troll be quieted?

    It’s hilarious, though, that he proves the point that basing a bet that includes a historical component is stupid.

    Good joke! Just look in your mirror at ‘realclimate’ where you back a bet by a professional climatologist, which is even heavily loaded with a historical component.

    What do we learn? Annan’s claim is consistent with the IPCC. Roger Pielke Jr’s claim is consistent with the weather and with the IPCC, Rahmstorf, Keenlyside, (pirates?), and again with Annan. What is not consistent is the way how climate scientists suddenly debate in public. The level seems to be down during La Niñas:-).

  31. #32 Majorajam
    May 17, 2008

    Apologies Tim, but I have to answer the ninny. Ninny, there are indeed cyclical factors that one would expect to wash over any 30 year period, negating the importance of including realized history. However, the system is still chaotic with multiple feedbacks both positive and negative, (ice sheets, sea ice, biosphere, cloud formation, etc.), and meaning that unforced differentiation can introduce some pre-cooked results into even a long-term forecast. In addition, there are these things called specification and sampling error (the latter applicable to GCMs only deductively in that these must be consistent with empirical outcomes) you may have heard of which will also cause random innovation around your point estimate. So you choice of bet is indeed giving Annan less than even odds by his own forecast. And what a fool he would have to be to turn it down…

    The more important bit is that this passive aggressive nonsense is a real bore. You claim that the ‘warmers’ are a ‘cult’ and yet won’t back up that self-parody with a simple and very favorable bet about climate sensitivity. You’re trying to show climate scientists lack the courage of their convictions by making it abundantly clear you have none. You won’t even take odds that climate sensitivity is, say, 1 degree per doubling, which would give you plenty of leeway in case there were a grain of truth to their conspiratorial cult to take over the world via the UN. But no, they must demonstrate their confidence by betting on a, (slightly stacked), coin toss while you lack the confidence even to bet that they overstate their case. What a hero.

    So why doesn’t the troll take the bet? My guess is because you’re a poisonous little man with too much time on his hands when he’s not using them to punch his angry inch like he caught it trying to break into his house. And this is just another way to get a kick. You poor poor fellow.

    “You’re not getting the point which is that for you to deny that increased CO2 is a warming force over the last 10 years requires belief that nothing else (natural or otherwise) could have given a cooling force”

    And your not getting the point which is that for you to believe C02 is the main driving force behind the warming, and will wreak havoc in a short period of time if we don’t take urgent action….. requires the belief that nothing (other than immediate, drastic regulatory actions) can save us.

    Unless of course there is no warming for 10 years, when the cooling effect of natural variations suddenly appears, putting the urgency on hold without warning…. and the term Global Warming fades away and Climate Change begins to take hold.

    Did we forget to include the cooling or suppressing effects of natural variation into the sense of urgency formula?

    I understand the trend and I understand things don’t happen in a linear way (due to natural variations) and I understand it would be wise to reduce and save and explore and create new etc…

    What I never understood was the sense of panic….10 and more years ago and today…which is the fuel behind imaginary images of planetary doom that are the driving force behind attempting to rush overeacting policies.

    And to drift off topic even further, think of it in terms of terrorism and the war in Iraq. Was the planning rushed? Was there overreaction? Was it well thought out? Was it a reaction to a trend line that created images of doom? Did it solve the problem?

    Irrational doom and gloom and the need for expedience….there’s a good combination to formulate rational decision making…..

    But hey, we haven’t had a terrorist attack in almost 8 years…..maybe rushed, overreacting policies based on worst case scenarios are a good thing.

    An ENSO event can be expected to affect different locations differently ie: heavy rains and flooding in Peru, severe droughts in Indonesia and parts of Australia….all depending on the variables local to that area…..altitude,latitude,proximity to large bodies of water or mountains etc… -Betula

    When the water to cause that rain and flooding in Peru moves across 4/5ths the breadth of the Pacific to get to Peru, and is carried by air currents that literally circumnavigate the globe, and the heat engine for the whole thing is 93 million miles away, it would be extremely difficult to say climate is caused locally, although if you say climate’s effects are felt locally, I don’t think anyone would disagree with that.

    Guys, do not feed the troll.

    Or trolls, in this case.

    “Guys, do not feed the troll.
    Or trolls, in this case.”

    Or at least feed them something worth eating…..we need to have them around so we can call them trolls and denialist twits to make us feel clever.

    Science will continue marching on with or without science denialists.

    And the earth will continue to warm whether you believe it or not.

    Reality’s a bitch.

    And now, via Annan, we have Pielkean arithmetic

    I guess if you squint and wave your hands, 23% is pretty close to 5%.

    Phoca says…

    “it would be extremely difficult to say climate is caused locally”

    This began at #48 when Harold Pierce stated “All climate is local”. You can read into that what you like, but I believe we are talking semantics…..location affects climate.

    This from the Colorado Climate Center……

    “The climate of local areas are profoundly affected by differences in elevation, and to a lesser degree, by the orientation of mountain ranges and valleys with respect to general air movements. Wide variations occur within short distances. The difference (35°) in annual mean temperature between Pikes Peak and Las Animas, 90 miles to the southeast, is about the same as that between southern Florida and Iceland. The average annual snowfall at Cubres in the southern mountains is nearly 300 inches; less than 30 miles away at Manassa in the San Luis Valley, snowfall is less than 25 inches. While temperature decreases, and precipitation generally increases with altitude, these patterns are modified by the orientation of mountain slopes with respect to the prevailing winds and by the effect of topographical features in creating local air movements.”

    Climate/microclimate…

    It comes down to scale, but to try to say that HPJr’s “All climate is local” eyebrow-raiser is to any real extent defensible, Betula, stretches credulity. Global climate exists, and it is affected by global-scale factors. There is no hiding from this.

    Methinks that it might be you who plays semantics, with your quotation and with your implication that HPJr is somehow correct.

    Permit me a metaphor.
