The Chart Chris Jackson Forgot To Show

December 30, 2020

Instead of using his bit of string on a board to illustrate the temperature and CO2 record of the Earth, Prof Jackson might have treated his audience in a more grown up fashion, and shown them the actual record:

If he had done, of course, he would have had a hard job convincing even the impressionable youngsters that carbon dioxide was controlling the climate!

    We must not confuse the kids with facts and evidence. Where would the future Gretas come from if they were given scientific evidence?

      Richard Lindzen is the only expert I would listen to on any of this !! MIT Emeritis. Cool head great brain with relevant & Genuine tertiary education, followed up by experience on the subject with 40 odd years of actual experience. And he says it is overblown for career motives. ( would ad embellished for lucrative gain from Renewables businesses, [ hence China making a bomb]
      I am a Scientist myself and fully concur with Professor Richard Lindzen.

        Plus very many. Always remember him giving a (UK) parliamentary committee a real education on CC – but they (apart from Stringer & Lilley) hadn’t a clue.

    Tempted to say I can feel this idiot – cannot bring myself to call Jackson a “Professor” as he is demonstrably compromised – squirming already but then it might prompt him to spout about attributional modelling trumping empirical evidence; I think most people will spot that as the crass attempt to selectively fit “facts” to “prove” a predetermined conclusion masquerading as a “theory”? …and I am not a scientist.

      The retrofitting of a belief with selective, dubious evidence is commonplace. HS2 is a prime example. Jackson cannot shift from an opinion based upon modelling so has to resort to what you allude.
      Well said Sir!

    I was a scientist and am disgusted at idiots like Jackson ruining non-scientists’ perception of what science really is. Rather like the Biased Broadcasting Corporation saying today that ‘Professor’ Ferguson is an “infectious diseases expert”, when all he is is an useless mathematical modeller.
    They must be giving out the title ‘Professor’ to those who demonstrate gross incompetence, ideally in an area outside their own specialisation.

      The IPCC’s Pachauri was always described as a “scientist”, when he was a railway engineer and economist. Economists such as Stern and Edenhofer are often given scientific credence.

    Did he think it would go unnoticed?

    I think he did.

    Professor is just a pay grade at university.

    • December 30, 2020 11:18 am

      GeoffB, In my day there was only one professor per department. Now they are all called professor. Also in my day THE Emeritus Professor of Petroleum Geology and Earth Sciences at Imperial was no other than the great Professor Robert Stoneley, the son of another Dr Robert Stoneley, the discoverer of Stoneley Waves. Now he WAS a professor!

      There are over 20,000 of them few of which are the traditional old professor who really knows his subject. Most seem to be young thrusting go-getters ( with lots of pal-reviewed publications on totally obscure aspects of their specialism) who crave publicity.

        I should have added that the financial model of Uni departments now makes professors business developers whose role is to bring in funding: sadly academia is as vulnerable as any business to the commercial requirements and TV appearances seem to be regarded as proof of expertise .

    I still struggle to find any justification for the farcical string curves presented by this “modern” manifestation of what it is to be a university professor. Indeed as he has two curves with one set of values in common only, where is the vertical axis on the right hand side? Ok I know he omitted (deliberately?) to add any annotation or scale but…..

    A pertinent question is, did he write the script or is he just a mouthpiece, the now acceptable face of Cyense on the BBC now post BLM handwringing by the BBC? Perhaps he will be the new even dumber and compliant Brian Pox, sorry Cox, slip of the digit on the keyboard?

    Also, given the subject matter and his supposed background and qualifications where does poor presentation and go to the back of the class stop and wilful lying with the deliberate intention to deceive, cause mental cruelty to children start?

      as i commented earlier on the last item .. how much of the subject and the detail was determined by the BBC producers/commissioning editors. Without the BBC showing the lectures on TV every year the RI would be a non-entity.
      Also, having watched episode 2 (another Imperial professor), apart from Jackson and a Hawaiian guy every guest has been female. More subtle wokeness? And the kids? when there is a live audience the demographics have been constant. Mainly white middle class kids who can be bothered to get their families to get them to London for the Lecture. Now we are using videos, with kids in school or at home, most of them at school, the mix of school kids has become very diverse (more reflective of inner London schools than the population as a whole). Again more subtle wokeness? I’m all for getting more kids involved, but social engineering .
      Actually given the amount of spurious man made climate change propaganda in these programmes so far, i wish fewer kids were exposed. You see them all nodding their heads, clapping like an NHS thursday night, taking it all in.

    I’m a climate change sceptic but when I showed this chart to one of my “warmist” friends, his smug response was: “How do they know what the temperature and CO2 levels were millions of years ago. Did they have someone there taking measurements?” I would like to know how to answer this question before showing the chart to anyone else.

    • December 30, 2020 12:06 pm

      Basically the sort of stuff Jackson presented – analysis of rocks, fossil etc

      This is a more up to date paper from Scotese, for instance, which gives more detail:

      https://www.researchgate.net/publication/309324713_A_NEW_GLOBAL_TEMPERATURE_CURVE_FOR_THE_PHANEROZOIChttps://www.researchgate.net/publication/309324713_A_NEW_GLOBAL_TEMPERATURE_CURVE_FOR_THE_PHANEROZOIC

    • December 30, 2020 1:11 pm

      Scotese is a very good resource:
      http://www.scotese.com/climate.htm

      ‘We can determine the past climate of the Earth by mapping the distribution of ancient coals, desert deposits, tropical soils, salt deposits, glacial material, as well as the distribution of plants and animals that are sensitive to climate, such as alligators, palm trees & mangrove swamps.’

      The main point being, as far as I understand, is that all proxies used for Earth history up to the around 1 million years ago, lack the spatial and temporal resolution to accurately determine the speed of changes or whether CO2 lags or leads temperature.

        Ice cores cure the problem and give the required resolution. Its the ice cores that prove that CO2 is changed by Temperature and not the other way around.

    • bobn permalink

      Principally by sampling ancient ice-cores. Two main sample areas have been used from drilling deep into Greenland (GRIP AND gisp2) and Antarctica (Vostok and EPICA) where the snow has fallen (not melted) and compacted for millions of years. These ice samples hold bubbles of historic air from which they can measure the air composition and temperatures from when the snow fell. They can also measure it from the composition of sediments laid down over millenia at various locations – often under today’s oceans which were not always underwater.
      The Antarctic based EPICA and Vostok Ice Cores show a repeating pattern of long periods of glaciation, (~100,000 years), when much of the Northern hemisphere is covered by ice sheets several kilometres deep. These are followed by much shorter warmer inter-glacial periods, (~10,000 years). The changes are driven by the orbital geometry of the earth around the sun. It can be modulated by the shorter term periodic behaviour of the sun. These facts controlling the earth’s climate are well documented and well understood. As the sun and our orbit cause the temp of the oceans to rise and fall, the solubility of CO2 in the ocean follows with a rise and fall. Seawater (and wine) will hold twice the CO2 at zero deg as at 30c (Sparkling wine stays bubbly longer when colder. Cold fizz tends not to gush out on opening but warmer bottles spray as more CO2 has been released from the liquid). So the sun causes temps to rise, forcing the warming oceans to lose CO2 into the atmosphere. A process known to every educated schoolchild but not to fake Profs at leftist community colleges.

        That would be a question, the answer to which I would pay to hear, that Prof Jackson should be made to answer: does CO2 (NOT carbon!!) lead or lag T?

    The climate change issue is a centennial time scale thing. What is the relevance of the million year time scale data presented here?

      At least – I think it’s him, I couldn’t watch the programme. I couldn’t bring myself to watch Dr Czerski last night either, though she seems unusually sensible for TV presenters to me. I was put off by the Radio Times blurb for tonight’s effort:

      “We would die without breathing oxygen, the raw material for all complex life, but another critical component of the atmosphere is carbon dioxide, a greenhouse gas that’s causing a dangerous rise in global warming. Tara [Dr Shine] considers how we might create a better, cleaner and more sustainable future as she looks at the carbon footprint of a loaf of bread and asks whether hydrogen might be the answer for heating and transport.”

      Perhaps plants are not considered a complex lifeform – I understand they don’t do well in the absence of CO2.

      Dr Tara Shine is here:
      https://www.tarashine.com/

      “Dr Tara Shine has dedicated over 20 years of her life to the pursuit of fairness between people and between people and the planet.”

      Good for her, I’m with her all the way for half of that statement. I don’t understand how we can even be relevant to a planet that would be 99.9999% the same if the entire atmosphere, and us with it, were blasted into space.

    The amount of CO2 estimated to have been in the Earth’s atmosphere in the early Archean is about 2,000 ppm. With water vapor this was enough to keep the planet from freezing because of the dim early Sun. It was enough to allow the evolution of life in sunlit waters that eventually gave rise to photosynthetic life. No catastrophic temperatures were involved except close to hydrothermal vents in the oceans. What the absolute temperature was is irrelevant. The planet has always been habitable once the late bombardment ended in the Hadean. Dr. Jackson is a geologist. He should know that… and probably does. It just doesn’t fit the global warming narrative he espouses.

    The problem is that these idiots like to virtue signal and being Leftist is currently fashionable. Ordinary people from the 1980’s and onwards are in the main. poorly educated so don’t question what they are told. How else can the fact that CO2 as a percentage of the atmosphere has risen from 0.03% to 0.04% be interpreted as an “emergency” or a “crisis” especially when its concentration was once 20% or 500x higher than it is now?

    The following is slightly off-topic but never the less relevant to poor science in other disciplines too!

    This idiocy isn’t confined to the climate either. Official dietary advice was, until relatively recently, to cut back on fatty food and eat more carbohydrates, the result? An epidemic of obesity and consequent heart problems. Then there was the government advice at around the the same time warning everyone that sunshine could cause cancer,. Parents were told to keep their children covered up and what was not covered was smeared with sunscreen. The result an epidemic of Rickets then, and a potential flurry of auto-immune diseases in the future!

    Why has it taken until just recently for the Pandemic Scientific ‘Advisors’ to make everyone aware of the protective properties of Vitamin D nine months after the start of the pandemic? I and my family and friends have been taking Vitamin D Pearls 5000iu since March!

    How did I know and they didn’t?

    It is depressing to see the scientists of today swallowing the alarmist junk without question. One just has to look at the history of CO2 and temperatures, the warming and cooling of the RWP, MWP and LIA to realise that there is nothing new about temperature change, This is a relatively stable period.

    Why, when currently CO 2 levels are over 400ppm, is that part of the graph appear to be lower than two other given measurements which are themselves lower than 400ppm?

  15. December 30, 2020 8:54 pm

    I am still waiting for the “fisics” of how a trace gas (CO2) causes warming of the atmosphere to such a degree that this alone causes all climate change.

    just catching up on last sundays papers . Sunday Times mag has a piece on Jackson – on being the first black scientist to do the RI Christmas Lecture . “He talks to Susie Mesure about tackling climate change and racism” . so it was always going to be a well balanced lecture wasnt it ? Worth a read just for a laugh
