All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

There is no empirical evidence to support climate alarmism. Malcolm Roberts vs the hack alarmists.


by Anthony Cox

ABC Insiders
Barrie Cassidy, David Leyonhjelm, Malcolm Roberts

Intrepid fellow that he is, Malcolm Roberts, newly elected senator on the PHON ticket, does not shy away from going into the Lion’s Den, or should that be the scalded cat’s litter-box, of the ABC. The ABC is a notorious  and biased advocate for the scams of alarmism and renewable energy.

The ABC can be expected to gun for Malcolm as Barrie Cassidy did in a desultory fashion on Insiders. Malcolm was more than a match for Cassidy as was David Leyonhjelm. While both Roberts and Leyonhjelm made a fool of Cassidy over the repugnant and sinister S.18C an important distinction between Leyonhjelm and Roberts over alarmism was apparent. Roberts opposes alarmism and renewables because they have no science to back them up and therefore measures like a CO2 tax have no justification. Leyonhjelm on the other hand does not quibble with alarmist science. He opposes a CO2 tax because no-where else in the world is this being done and therefore it would be fool-hardy for Australia to go it alone. An important distinction.

Malcolm also appeared on the ABC’s youth orientated Tripe J’s Hack and spoke sense. Naturally this did not impress and the response was to get some alarmist experts to refute what Malcolm had said. If it were not serious because of the vast amounts of money the government is wasting on alarmism and
renewables it would be hilarious. The experts the hack got to repudiate Roberts were: JohnCook and Steve Sherwood.

I have had some stoushes with Cook who from my experience turns up, adopts a condescending tone and then disappears when awkward questions such as how his paper on the consensusinstead proves there is no consensus, are asked.

At Hack Cook attempts to contradict Roberts reasonable conclusion that there is nothing unusual about the current climate by using the 4 atomic bombs comparison. This comparison is typical of alarmists. They have no facts so they resort to grotesque images and hyperbole. Supposedly human influence on the environment is like 4 atomic bombs going off every second. This is beyond stupid and it is alarming that not only people like Cook use this rubbish as Joanne Nova shows but supposedly top academics like Mike Sandiford. I deal with Sandiford at a previous post here which shows what is really behind this absurdity: misanthropy.

In any event the current climate is completely benign compared to some of the huge variations in past changes brought about by nature in Heinrich and Dansgaard-Oeschger events



The slight increase in temperature over the last century of less than 1C cannot be compared with past natural increases and decreases of temperature over similar periods or less of up to 12C:



Cook goes on to attempt to refute Malcolm’s perfectly reasonable observation that temperature has paused. Ken Stewart convincingly shows this pause:



Cook’s refutation goes further into Alice in Wonderland territory when he says the satellites, which show the pause, are really just measuring the upper atmosphere where cooling is consistent with alarmism. This is wrong in many ways. The satellites do measure the surface and the upper atmosphere has not cooled for as long as the pause has occurred:


Finally, Hack wheels out the big gun of Steve Sherwood to refute Malcolm’s claims that humans are not causing the increase in CO2. Sherwood is infamous; he has been inventing the Tropical Hot Spot (THS), the Holy Grail of alarmism, for years. As far back as 2008 Sherwood was discovering a THS where none existed. This 2008 paper typifies alarmism. Sherwood repudiated the instrument data because it did not show a THS and developed a windshear model which showed if there was windshear there would be warming. The stupidity of this was the instruments which were not good enough for temperature were used to establish windshear and model predicted temperature. In short he invented the evidence and called it modelling. And Sherwood keeps doing this as Jo Nova noted.

It is now well established that the increase in CO2 over the 20thC is almost entirely natural. The Airborne Fraction which is the % of Human CO2 in the atmosphere has not changed as the atmospheric CO2 increases:



As I explain if the proportion of Human CO2 is not increasing it must mean that nature is causing the increase. This is consistent with Henrys Law as Jamal Munshi explains in his paper. But facts are irrelevant to alarmists. They believe in their ideology. This is why we need someone like Malcolm Roberts in the senate. He won’t change their beliefs but hopefully he will convince the people in the middle and if enough people voice their opposition to this oppressive ideology of global warming the true believers will be removed from their undeserved positions of influence.


So despite the idiots at Hack supposedly repudiating Roberts they have in fact once again demonstrated the truth of what Malcolm says:
there is no empirical evidence to support alarmism.

  2. I attempted to email this to Senator elect roberts, but the one Nation address no longer seems to be operating, so was awaiting his electoraloffice to be set up. However I will take the oportunity to post it here.

    Dear Senator elect Roberts,

    I have noted your remarks on the ABC Lateline and Insiders programs concerning climate change. In particular I noted your request to Mr Cassidy for empirical evidence of anthropogenic global warming.

    I will limit myself to two graphs of temperature and atmospheric CO2 data and how they relate to your statement that there is no empirical evidence for ‘unusual’ temperature trends.

    This graph of global temperatures from NASA’s Gistemp data set and atmospheric CO2 concentration as measured by the Muana Loa site in Hawaii which began operating in 1958.

    http://www.woodfortrees.org/plot/gistemp/from:1958/mean:12/plot/esrl-co2/from:1958/normalise/scale:1/offset:0.36

    If you are one of those who prefers the “unadjusted “satellite data, which began in 1979, the equivalent graph is here:

    http://www.woodfortrees.org/plot/gistemp/from:1958/mean:12/plot/esrl-co2/from:1958/normalise/scale:0.9/offset:0.35/plot/uah/mean:12/offset:0.4/plot/rss/mean:12/offset:0.3

    The sawtooth pattern of the CO2 concentration is due to the growing and dormant seasons in the northern hemisphere, where most of the worlds plants, particularly those in deciduous forests. are located.

    The Gistemp data gives a value for the Equilibrium Climate Sensitivity (ECS), the rise in temperature with doubling of CO2 concentration of 2.5 °C, within the IPCC range predicted by theory of 1.5 to 4.5 °C.

    The satellite data, being for a shorter period and being more “noisy” has higher error margins for the trend values. The trends and 2? confidence limits for Gistemp, UAH and RSS are respectively:

    Trend: 0.155 ±0.021 °C/decade (2?)

    Trend: 0.150 ±0.064 °C/decade (2?)

    Trend: 0.130 ±0.063 °C/decade (2?)

    The satellite data give ECS Values of 2.2 and 1.9 °C respectively in statistical agreement with the Gistemp data and also within the IPCC range predicted by the theory.

    The observations therefore match the theory, and do not do so if only “natural” rather than anthropogenic forcings are considered.

    Sincerely,

    Dr Philip Shehan

      Here is a reply from Anthony Cox:

      Climate sensitivity estimates, which means the temperature response to 2 x CO2, are declining:

      http://joannenova.com.au/2015/06/shrinking-climate-sensitivity-estimates/

      There is a strong argument that ECS has been reached:

      The IPCC and general alarmist predictions for ECS are based on erroneous estimates for CO2 residency as I discuss here in the context of the dispute between the Essenhigh, Cawley and Knoor papers:

      http://theclimatescepticsparty.blogspot.com.au/2013/01/defective-agw-science.html

      On residency see also this summary of residency studies which shows the IPCC analysis is the outlier:

      http://c3headlines.typepad.com/.a/6a010536b58035970c0120a5e507c9970c-pi

      And professor Gösta Pettersson’s work:

      https://daedalearth.files.wordpress.com/2013/09/paper3.pdf


      In respect of the temperature indices, GISS is also clearly an outlier and there is no doubt that there is a pause, at least with UAH, and RSS before the recent amendment to their algorithm as Ken Stewart’s analysis shows.

      In respect of whether humans are the source of the CO2 increase Dr Shehan has not addressed my points in the article and I redirect him to my analysis of Knoor’s paper:

  4. Thanks to Anthony for his comments. My response:

    All Ms Nova’s graph in the first link shows is that over time determinations of the selected ECS appear to be converging on a particular value within the original IPCC range of 1.5 to 4.5 °C. One would hope that this would be the case , even if the value being converged on is in the lower end of the range.

    It is incorrect to draw some kind of trend line and extrapolate that at some time in the future will be zero.

    The second link is says that if the ECS is 3 0 or 2.5 °C it is almost impossible to restrict the rise in temperature to 1.5 °C above pre=industrial levels. I agree with that assessment.

    In fact the temperature rise in the graph of 1.25 C since 1800 with a CO2 concentration rise from 280 to 400 ppm if the ECS is 2.5 °C is in agreement with my determination of an ECS of 2.50 ± 0.35 °C based on a Gistemp temperature rise of 0.907 ± 0.12 from 1958 to the end of June 2016 and a rise in CO2 concentration of 315 ppm to 404 ppm over that period.

    The claim that humans are not responsible for the rise in CO2 since the industrial revolution is contestable to say the least and that rise correlates extremely well with temperature rise since that time:

    https://www.esr.org/outreach/climate_change/mans_impact/co2_new.jpg

    http://static.skepticalscience.com/pics/AMTI.png

    But in any case this does not affect the case that there is no basis for Roberts’ statement that the evidence shows that there has been no unusual warming.

    Similarly, your other links, while interesting are not relevant on this point.

    That is there is empirical evidence that there has been unusual warming , contrary to Roberts’ claims.

    1. Anthony Cox replies to Phillip Shehan:

      Philip; you are not drawing the right conclusion from the second link which I post again:

      http://joannenova.com.au/2015/12/the-ipcc-doesnt-believe-its-own-models-the-1-5c-ambitious-target-400ppm-were-already-there/

      The point about this is whatever ECS you believe in – 2 – 3C – we are at least 50% there now; the table explains this:



      Year CO2 (ppm) log2 (C/Co) Warming Warming
      (ECS of 3°C) (ECS of 2.5°C)
      1800 280 0 0° 0°
      2015 400 0.51 1.5° 1.25°
      2030 430 0.62 1.8° 1.5°
      2040 450 0.68 2.04° 1.7°
      2047 465 0.73 2.2° 1.82°
      2055 480 0.78 2.34° 1.94°
      2060 490 0.8 2.4° 2.0°

      And you ignore the log2 column which gives a proper figure for ECS. ECS for 2xCO2 is imply calculated. Based on average amount of solar radiation received on Earth:
      Sin=(1-a)FoHr^2
      Where a is albedo, Fo is the total solar radiative flux [w/m2] and Hr^2 is the cross-section of Earth.
      Energy radiated by Earth is:
      Sout= eQ4Hr^2T^4
      Where e is emissivity, Q the Stephan-Boltzman constant, 4Hr^2 the total area of Earth and T the temperature in K.
      At equilibrium Sin=Sout.
      Deriving we achieve:
      (1-a)Fo=eQ4T^4
      The average albedo is 0.297, solar irradiance 1366W/m2; assuming a blackbody e=1 so we have:
      (1-0.297)1366=5.67x10^-8(4)T^4
      Which gives T=255K; so the above becomes 255-273=-18C
      With e=0.612 the equation becomes:
      (1-0.297)1366=0.612(5.67x10^-8)4T^4
      Which gives T=288K - 273=15C
      The difference between the 2 temperatures [blackbody and real, that is with a greenhouse atmosphere] is 15-(-18)=33C; the greenhouse temperature.
      So with Earth reflecting 0.297 and emitting 0.612 =0.909 the amount of energy that Earth absorbs is:
      (1-0.909)1366=124W/m2. 124W/m2 has produced 33C. The sensitivity is therefore:
      33/124=0.27K/W/m2
      The radiative forcing for CO2 is:
      (5.35)In(C/Co)W/m2 [from Table 3 http://folk.uio.no/gunnarmy/paper/myhre_grl98.pdf }
      2XCO2=(5.35)In(2)=3.7W/m2 [the official IPCC forcing]
      So, the temperature increase from 2XCO2 is:
      (0.27)(3.7)=1C
      This a lower figure than calculated by either F&R or Hansen et al but I still think it is too high. Why? Clouds.

    2. Geoff, I beg to differ, and so does Ms Nova. She writes:

      "Apparently we want to set Earth’s climate control knob at 1.5 C above the Little Ice Age...If the climate modelers are right, and equilibrium climate sensitivity is 3 C, the CO2 concentration we need to aim for is … wait… 400 ppm. How many years have we got to change the whole “human emissions” equilibrium and discover 100% clean energy? Answer: No years."

      Ms Nova is assuming that everyone is using the figure of 3 C for an ECS. That is not true. The IPCC range for that value is 1.5 to 4.5 C, but the actual value is probably at the lower end, between 2 and 2.5 C as the second link shows (see my reply to Alan below) in line with my empirical calculations based on temperature and CO2 data.

      Ms Nova's argument is that at the current value of 400 ppm, we are already 1.5 C above the pre-industrial temperature.

      Well, as we are not 1.5 C above the pre-industrial level, with a CO2 concentration of 400 ppm, Ms Nova's assumption that the ECS is 3 C appears to too high.

      And in fact I have undertaken the reverse procedure, taking the actual CO2 and temperature data for periods of time,from 1959 when Muana Loa CO2 data began and matching it with Gistemp data, and again from 1979 when satellite data became available.

      The error margins for short term data are high but the calculated ECS values of 2.5± 0.4 °C and 2.2 ± 0.9 °C are within the IPCC range.

      But if you look at data going back to 1850,you get an ECS value of 2.04 ± 0.07 °C.

      http://oi46.tinypic.com/29faz45.jpg

      The error margin is lower, but in statistical agreement with the data for shorter periods.

      The ECS is not directly calculated from solar radiation. If the atmosphere was CO2 alone the warming vs concentration curve looks like this:

      https://knowledgedrift.files.wordpress.com/2010/05/log1-co2.jpg

      Here the warming is expressed in the energy per square meter at the surface, which converts to an increase in temperature of 1.1 C with doubling of CO2 concentration. What makes the cdetermination of the ECS for the earths amosphere are the feed back mechanisms, positivr and negative.

      One positive feedback is that the warmer the atmosphere the more water vapour it can hold, and H2O is itself a greenhouse gas. further warming the atmosphere.

      On the other hand that increased water vapour can form clouds, which shield the surface form the sun - a negative feedback.

      These are just two mechanisms, and the difficulty in working out how much feedbacks add to or subtract from the warming due to increasing CO2 alone is why the range has been stuck at 1.5 to 4.5 C for decades.

      But I agree with Ms Nova that it is unlikely that CO2 concentrations can be reduced enough to prevent the temperatures from exceeding 1.5 C above pre industrial levels.

    3. Anthony Cox reply to Dr Shehan.

      Philip, you are tying yourself in knots. And misrepresenting what Jo is saying: which is even if there is a delay in the effect of the heating from CO2 as defined by the ECS, which there is not, we are more than ½ way there. That’s all.

      And the point of the declining estimates for climate sensitivity are nothing more than the IPCC and climate researchers realising the so-called heating effect from 2xCO2 is not as great as they originally estimated.

      As for the ECS and the supposed delay in the heating effect from 2xCO2. This is wrong for a number of reasons.

      1 CO2 residency, the period CO2 lasts in the atmosphere, is much less than alarmism estimates. My first comment provides many sources for this.

      2 The missing heat is not stored on Earth. It is not in the oceans as even Hansen was forced to admit:

      http://www.abc.net.au/news/2011-05-02/cox2c-stockwell---honest-jim3a-the-science-is-not-settled/1031292

      http://www.rochester.edu/news/show.php?id=3420

      What these show is the oceans are NOT storing the missing heat. The climate responds fairly quickly to forcing and does not store heat.

      3 The idea that there are long delays in climate response was contradicted as far back as 2001 when Trenberth wrote his paper:

      http://www.cgd.ucar.edu/cas/papers/2000JD000298.pdf

      So to recap: even if you accept the idea of ECS, which is simply a delay in the heating response to 2xCO2 we are more than 50% past the figure which is DECLINING in the estimates. But there is strong evidence against a delay in climate response and therefore an ECS because CO2 does not last as long as alarmists have estimated and heat is not stored in the oceans.

  6. Alan, you are failing to distinguish between graphs which contain data which lend themselves to extrapolation and those that do not.

    Ms Novas graph shows various determinations of the ECS which appear to be converging on a value within the expected range. that is what one would hope would happen as understanding and data accumulates. the fact that it is converging on a value at the lower end of the expected range does not mean that you can take some line and extrapolate outside the range.

    There is no theoretical reason as to why the figure should decrease with time. Especially when the data on the graph appears to have selected high determinations in earlier years and ignored lower values to give a downward slope to the trend line.

    For example here are just some of the values that do not appear on the graph.

    Lorius 1990 examined Vostok ice core data and calculates a range of 3 to 4°C.

    Hoffert 1992 reconstructs two paleoclimate records (one colder, one warmer) to yield a range 1.4 to 3.2°C.

    Hansen 1993 looks at the last 20,000 years when the last ice age ended and empirically calculates a climate sensitivity of 3 ± 1°C.

    Gregory 2002 used observations of ocean heat uptake to calculate a minimum climate sensitivity of 1.5.

    Chylek 2007 examines the period from the Last Glacial Maximum to Holocene transition. They calculate a climate sensitivy range of 1.3°C and 2.3°C.

    Tung 2007 performs statistical analysis on 20th century temperature response to the solar cycle to calculate a range 2.3 to 4.1°C.

    Bender 2010 looks at the climate response to the 1991 Mount Pinatubo eruption to constrain climate sensitivity to 1.7 to 4.1°C.

    Other graphs show data where there is an expected theoretical relationship between the values on the vertical and horizontal axis.

    For example, there is an theoretical expectation that if atmospheric CO2 levels rise, atmospheric temperatures will rise. And the ECS is a paramater value that gives a value for the relationship.

    So you can plot a graph like this which relates temperature to the log of CO2:

    http://oi46.tinypic.com/29faz45.jpg

    The mathematical relationship between the quantities allows one to extrapolate along the line to predict what the future temperature willbe for a given future CO2 concentration.

      You leftist CAGW worshippers hate capitalism even though you reap the benefits. If 'big coal/oil (such a childish expression) is so terrible, why depend upon it any longer, contributing to the CAGW 'problem'? You can divorce yourselves from it and totally stop contributing your share of that evil CO2, right now! So GO!

      Buy some land somewhere and make sure there's no electricity provided by the local (big coal/oil powered) electricity supply, no (fossil fuel powered) cars, trucks, motorbikes, lawnmowers - anything that burns fossil fuels and no roads; and live in your clean, green utopia without it.

      Power your new world with your touted ultra reliable 'renewable' energy sources (i.e. wind turbines / solar) and eat the birds that they kill for food, but you'll have to cook them on an open fire, because the electricity won't stay on long enough to cook them in an electric range and of course, gas will be forbidden...

      Prove to us lunatics and environmental vandals how great your green utopia without depending 'big coal/oil' really is and you might even convince us to (NOT!) join you.

      Whilst you are still living in a world where your evil 'big coal/oil' prevails, you are all hypocrites so you should either shut up, or get out of the world that literally runs on the energy source you have demonized.
      Go and live in your clean, green utopia and enjoy it. Do it now, but you won't drag the rest of us down there with you, mainly because you yourselves would never go there either!

      You all love to preach the trendy leftist CAGW dogma and chant the alarmist mantra, but at the end of the day, you're all full of it...

      If you were even slightly genuine in your belief of your chosen morbid religion - CAGW and Climate Change Alarmism: you would lead by example, instead of preaching to us how we should live, whilst still living in and enjoying the benefits of a society fuelled by the evil 'big coal/oil' you claim is destroying the planet...
