Climate Is Not Difficult

I’m about to save the government $29 billion/year in climate research.

Earth’s climate is driven by changes in Earth’s orbit. Because of eccentricity and axial wobble, the length of different seasons varies over time. That is why we have ice ages and inter-glacials.

Solubility of CO2 in seawater varies with temperature. When temperatures increase, the oceans outgas CO2 – and vice-versa. That is the first thing freshman geology students learn, and is why the CO2 curve follows the temperature curve. It is also why a warm beer bubbles over when opened. Only a complete moron or a climate scientist would confuse that relationship. But I repeat myself.

    Is there a good reference work on “axial wobble” to share? (I’m going for my do-it-yourself, study-at-home Masters in climate science).

  2. Eliza says:

    This is I dont understand why climate scientist keep on publishing C02 sensitivity papers (now its “down” to 1.6C/century, according to Curry and Crock), when Co2 ALWAYS follows temperature. These papers must be all crock. Basically C02 most likely in the earths atmosphere has ZERO effect of Temp

  3. Eliza says:

    This is why…

  4. Tom In Indy says:

    Is there an explanation for the “sideways” temperature following the most recent peak in temperature, roughly the last ~10,000 years? If you look at previous peaks, temperature falls “quickly” following the peak. However, the pattern is different following the most recent peak.

    • Earth is closest to the sun now during January, so there won’t be an ice age for a long time.

      • Shazaam says:

        And yet the grant-sucking tax parasites haven’t figured-out that tiny detail as a possible “explanation” for the rise in the Antarctic sea ice.

      • Gail Combs says:

        That seems to be a major point of contention among quaternary scientists. (Forget the CO2 bafflegab needed to get published.)

        2012 Determining the natural length of the current interglacial
        ….model experiments suggest that in the current orbital configuration—which is characterized by a weak minimum in summer insolation—glacial inception would require CO2 concentrations below preindustrial levels of 280 ppmv (refs 2, 3, 4). However, the precise CO2 threshold4, 5, 6 as well as the timing of the hypothetical next glaciation7 remain unclear. Past interglacials can be used to draw analogies with the present, provided their duration is known….. The glacial inception during Marine Isotope sub-Stage 19c, a close analogue for the present interglacial, occurred near the summer insolation minimum, suggesting that the interglacial was not prolonged by subdued radiative forcing7. Assuming that ice growth mainly responds to insolation and CO2 forcing, this analogy suggests that the end of the current interglacial would occur within the next 1500 years, if atmospheric CO2 concentrations did not exceed 240±5?ppmv.

        Another:

        …Because the intensities of the 397kaBP and present insolation minima are very similar, we conclude that under natural boundary conditions the present insolation minimum holds the potential to terminate the Holocene interglacial.
        http://folk.uib.no/abo007/share/papers/eemian_and_lgi/mueller_pross07.qsr.pdf

        Lisiecki and Raymo (Paleooceanography, 2005) came to much the same conclusion.

        “Recent research has focused on MIS 11 as a possible analog for the present interglacial [e.g., Loutre and Berger, 2003; EPICA community members, 2004] because both occur during times of low eccentricity. The LR04 age model establishes that MIS 11 spans two precession cycles, with 18O values below 3.6o/oo for 20 kyr, from 398-418 ka. In comparison, stages 9 and 5 remained below 3.6o/oo for 13 and 12 kyr, respectively, and the Holocene interglacial has lasted 11 kyr so far. In the LR04 age model, the average LSR of 29 sites is the same from 398-418 ka as from 250-650 ka; consequently, stage 11 is unlikely to be artificially stretched. However, the June 21 insolation minimum at 65N during MIS 11 is only 489 W/m2, much less pronounced than the present minimum of 474 W/m2. In addition, current insolation values are not predicted to return to the high values of late MIS 11 for another 65 kyr. We propose that this effectively precludes a ‘double precession-cycle’ interglacial [e.g., Raymo, 1997] in the Holocene without human influence.

        This is the perspective. The summer solstice insulation minimum during MIS-11 at 65N was 489 Watt/m2 and it was 474 Watt/m2 in ~2005 (Lisiecki and Raymo, 2005). You need 15 Watt/m2 to get to the insolation minimum in MIS-11. I am not familiar with any CO2 estimates which correlate with a 15 Watt/m2 rise in atmospheric forcing.

        Chronis Tzedakis (2010) did an exhaustive look at the MIS-1/MIS-11/MIS-19 conundrum. http://www.clim-past.net/6/131/2010/cp-6-131-2010.pdf

        While the astronomical analogy between MIS 1 and MIS11 has been incorporated in mainstream literature, there is a distinct difference between the two intervals: the Holocene contains one insolation peak so far, while the MIS 11 interval of full interglacial conditions (Substage 11c of the marine isotopic stratigraphy) extends over two insolation peaks. Thus an interesting situation has arisen with regard to the precise alignment of the two intervals.

        The two schemes lead to very different conclusions about the length of the current interglacial, in the absence of anthropogenic forcing, …

        With the end of MIS 11 full interglacial conditions and the start of ice accumulation estimated to have occurred at 395 kyr BP (de Abreu et al., 2005; Ruddiman 2005a, 2007), the precessional alignment would suggest that the Holocene is nearing its end, while the obliquity alignment would suggest it has another 12,000 years to run its course.

        “In this view, the two Terminations are incommensurate and MIS-1 is analogous only to the second part of MIS-11c….

        On balance, what emerges is that projections on the natural duration of the current interglacial depend on the choice of analogue, while corroboration or refutation of the “early anthropogenic hypothesis” on the basis of comparisons with earlier interglacials remains irritatingly inconclusive.

        Even during the only post-MPT interglacial to make it past about half a precession cycle it still got awfully cold between MIS-11?s two insolation peaks and the climate was a wee bit rocky. So no matter how you slice it the one thing we can be sure is NOT going to happen is CAGW.

        Investigating the processes that led to the end of the last interglacial period is relevant for understanding how our ongoing interglacial will end, which has been a matter of much debate…..

        …The onset of the LEAP occurred within less than two decades, demonstrating the existence of a sharp threshold, which must be near 416 Wm2, which is the 65oN July insolation for 118 kyr BP (ref. 9). This value is only slightly below today’s value of 428 Wm2. Insolation will remain at this level slightly above the inception for the next 4,000 years before it then increases again.” http://folk.uib.no/abo007/share/papers/eemian_and_lgi/sirocko_seelos05.nat.pdf

        For those who want to dig deep into the subject of glacial inception here is a starting point but be aware you are looking at hours of reading – mostly direct quotes from the literature.
        link

        The science is decidedly NOT settled, however perparing for colder weather makes a lot more sense that the idiocy we are seeing now. (It is also fun to rub the warmist noses into the possibility of glaciation and have the pee-reviewed papers they so love to back you up.)

        • It is not a question of insolation – it is length of the seasons.

        • Gail Combs says:

          Steve, that is why I said there is a bit of controversy on the subject going on.

          Bits and pieces from various sites:
          It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables is not due to the total amount of solar energy reaching Earth. The three Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.link

          This is why the amount of solar energy on 21st of June at 65? N is calculated and compared in all the different papers. MIS-19 which occurred somewhere within or at the Mid Pleistocene Transition, MIS-11 (the Holsteinian) and MIS-1 (the Holocene) all occurred at a 400kyr eccentricity minimum cycle, that is why they are considered analogs and have been studied closely.
          ………………..

          Eccentriticy: currently, we are in an orbit of low eccentricity

          At year 2007 AD, Spring = about 92+3/4 days and getting shorter, Summer = about 93+2/3 days and getting longer, Autumn = about 89+5/6 days and getting longer, Winter = slightly less than 89 days and getting shorter, with an average season length in this data set of about 91 days 7h 27m 15s. The significance of the changing season lengths will become obvious in chart #2, next below.

          (Spring + Autumn = Summer + Winter) link

          So the difference in season length between Summer and Winter is ~ 4 days.
          ………………………..

          axial tilt: currently, the axis of rotation for the earth is tilted at 23.5°
          However, this value changes from a minimum of 22.5° to a maximum of 24.5° and takes 41,000 years to complete one cycle less tilt also increases the difference in radiation receipts between the equatorial and polar regions.

          One hypothesis for Earth’s reaction to a smaller degree of axial tilt is that it would promote the growth of ice sheets. This response would be due to a warmer winter, in which warmer air would be able to hold more moisture, and subsequently produce a greater amount of snowfall. In addition, summer temperatures would be cooler, resulting in less melting of the winter’s accumulation.   At present, axial tilt is in the middle of its range.
          ……………………….

          Precession: currently this means that the Northern Hemisphere will experience winter when the Earth is closest from the Sun and summer when the Earth is furthest to the Sun.

          I would think the comment about “….a warmer winter, in which warmer air would be able to hold more moisture, and subsequently produce a greater amount of snowfall. In addition, summer temperatures would be cooler, resulting in less melting of the winter’s accumulation….” would again apply. It is not the cold, it is the warm wet winters and cool summers that are the ‘I Gotchas.’

          It is interesting to note the possible analog for the Holocene, MIS 11 was warmer than during the Holocene according to pollen records from Europe, Asia, Australia, New Zealand and America.

          MIS 11 is also the warmest period in Brunhes chron recorded in Lake Baikal. The loess sequences in Northern China show evidence that the summer monsoon during MIS 11 was particularly strengthened, which is typical of warmer climate. Sea-level highstands at about +20 m, dated at about MIS 11, were identified in northern Alaska, in England, in Bermuda and the Bahamas and in the Cariaco Basin. MIS 11 is also characterized by unusual carbonate plankton blooms in high latitudes and massive coral reef build-up
          . https://pangea.stanford.edu/research/Oceans/GES205/MIS11FutureClimateModeling.pdf

          There is the one tiny point that most everyone seems to miss — 65 million years of cooling
          The Holocene is a lot cooler than the Holsteinian (MIS-11) as mentioned above and I have no idea if that lower temperature starting point is taken into account or would have any effect.

        • cdquarles says:

          Gail, if I’m not mistaken, the current axial tilt is 23.4 degrees and declining.

        • cdquarles says:

          Here is a link to orbital parameters, with code: http://www.jhu.edu/~lhinnov1/hinnovresearch/earthsorbitalparameters.htm. I have not checked the code for accuracy or precision.

      • David A says:

        Does this mean that the earth, via the SH oceans, intakes more solar energy (due to the heat capacity of the oceans) then if the more intense solar energy was striking the NH?

        • geran says:

          Yes. At closest distance to the Sun, the increase in solar irradiance is about 6% more than when the Earth is farthest.

        • The theory is that ice ages occur when Northern Hemisphere summers are short and receive the brightest sunshine, while winters are long and dark.

          >>>>>>>>>>>>>>>
          Sorry Steve the data says different:

          Loutre and Berger’s 2003 paper was based on an astronomical model and looked at orbital mechanics and model results (therory.) It was at the time, considered a landmark paper and a widely quoted and discussed. That paper predicted that the current interglacial, the Holocene, might last another 50,000 years, particularly if CO2 were factored in.

          However that paper was followed in 2005 by another paper by Lisieki and Raymo. This paper was not based on theory and models but instead took an exhaustive look at 57 globally distributed deep ocean cores. They concluded:

          …consequently, stage 11 is unlikely to be artificially stretched. However, the June 21 insolation minimum at 65N during MIS 11 is only 489 W/m2, much less pronounced than the present minimum of 474 W/m2. In addition, current insolation values are not predicted to return to the high values of late MIS 11 for another 65 kyr. We propose that this effectively precludes a ‘double precession-cycle’ interglacial [e.g., Raymo, 1997] in the Holocene without human influence.
          http://web.pdx.edu/~chulbe/COURSES/QCLIM/reprints/LisieckiRaymo_preprint.pdf

          A fall 2012 paper “Can we predict the duration of an interglacial? “ gives the solar insolation on 21st of June at 65? N (The summer solstice in the Northern Hemisphere) for termination of several interglacials
          Current value – insolation = 479 W m?2,
          MIS 7e – insolation = 463 W m?2,
          MIS 11c – insolation = 466 W m?2,
          MIS 13a – insolation = 500 W m?2,
          MIS 15a – insolation = 480 W m?2,
          MIS 17 – insolation = 477 W m?2,

          NOAA also gives calculated values:
          Holocene peak insolation: 522.5 Wm-2
          depth of the last ice age – around 463 Wm?2
          NOW (modern Warm Period) 476Wm-2

          Will an extra two days of summer and two days less of winter make the difference? Will something else like a couple of nasty volcanos tip the balance the other way? Will the sea ice building in the Antarctic reflect enough energy to cause a difference? Will the solar minimum we may be heading into along with the increase in volcanic activity that seems to accompany it be a tipping point? Heck if I know but I think we are near enough the ‘balance point’ between glacial and interglacial that this is what scientists should be looking at instead of chasing a harmless plant food.

        • At peak eccentricity, there is nearly a month difference between glacial winter length and interglacial winter length.

        • David A says:

          “The theory is that ice ages occur when Northern Hemisphere summers are short and receive the brightest sunshine, while winters are long and dark”
          ==============================================
          Yet precession makes a complete cycle every 24000 to 25000 years. So, according to the data, we only kick into a full blown glacial advance every fourth time or so we complete the cycle.

      • John F. Hultquist says:

        60,000 years, more or less
        http://motls.blogspot.com/2012/03/next-peak-of-ice-age-year-60000-ad.html

        Now, about this cold water and CO2 thing:
        Why, when I drop and ice cube into a class of already cold soda, does it fizz? Maybe this is an optical illusion and I’m seeing CO2 from the air in the room being violently taken into the liquid. One of life’s little mysteries!

        • mjc says:

          Two entirely different reactions/reasons for CO2 leaving the liquid. The CO2 out gassing in a can of warm soda or beer causes the pressure in the container to build, which when opened causes the violent reaction.

          The ice cube, or any solid object, especially one with many pores and cavities on the surface, causes the CO2 to rapidly leave the liquid due to nucleation.

          The results can be the same…but the processes are vastly different.

      • Tom In Indy says:

        If your claim is true, and I have no reason to doubt it, then the implication is that the earth was not closest to sun in January immediately following the last 4 peaks that are visible in your graph. There is no ~ 10,000 year “pause” 😉 in temperature decline following the last 4 peaks. Does anyone know if it’s true that the earth was not closest to sun in January immediately following the last 4 peaks? Is there an app for that? 🙂

      • cdquarles says:

        Strictly speaking, Tony, we are in an Ice Age now, living in an interglacial (meaning slightly less ice, especially on land at the ‘mid’ latitudes); unless they’ve changed the definition again. Ice Age = large amounts of perennial ice anywhere on the planet, back when I was introduced to the concept.

        • mjc says:

          That’s still the definition…but, it probably won’t be for long.

          These believers in a static climate can’t have anything that shows there were past changes that weren’t caused by human intervention.

  5. All the current discussion re climate sensitivity is a complete waste of time and effort.
    The modelling approach is inherently of no value for predicting future temperature with any calculable certainty because of the difficulty of specifying the initial conditions of a sufficiently fine grained spatio-temporal grid of a large number of variables with sufficient precision prior to multiple iterations. For a complete discussion of this see Essex:
    https://www.youtube.com/watch?v=hvhipLNeda4
    Models are often tuned by running them backwards against several decades of observation, this is
    much too short a period to correlate outputs with observation when the controlling natural quasi-periodicities of most interest are in the centennial and especially in the key millennial range. Tuning to these longer periodicities is beyond any computing capacity when using reductionist models with a large number of variables unless these long wave natural periodicities are somehow built into the model structure ab initio.
    Earth’s climate is the result of resonances and beats between various quasi-cyclic processes of varying wavelengths combined with endogenous secular earth processes such as, for example, plate tectonics. It is not possible to forecast the future unless we have a good understanding of the relation of the climate of the present time to the current phases of these different interacting natural quasi-periodicities which fall into two main categories.
    a) The orbital long wave Milankovitch eccentricity,obliquity and precessional cycles which are modulated by
    b) Solar “activity” cycles with possibly multi-millennial, millennial, centennial and decadal time scales.
    The convolution of the a and b drivers is mediated through the great oceanic current and atmospheric pressure systems to produce the earth’s climate and weather.
    After establishing where we are relative to the long wave periodicities, to help forecast decadal changes, we can then look at where earth is in time relative to the periodicities of the PDO, AMO and NAO and ENSO indices and based on past patterns make reasonable forecasts for future decadal periods.
    In addition to these quasi-periodic processes we must also be aware of endogenous earth changes in geomagnetic field strength, volcanic activity and at really long time scales the plate tectonic movements and disposition of the land masses.
    For forecasts of the probable coming cooling based on the natural 1000 and 60 year periodicities in the temperature data and using the neutron count and 10 Be data as the best proxy for solar “activity” see the series of posts at

      In other words. we’ve barely scratched the surface of knowing the known variables…let alone knowing exactly how many variables there are.

      • Gail Combs says:

    • nielszoo says:

      Amen, look at the large energy systems and their interrelationships and periodicity.

      (And we’ll get a whole lot further along if we quit concentrating on the mix of trace gasses in our atmosphere… especially on CO2, whose only significant effect comes from the fact that it’s needed for plant growth and the amount of vegetation in the seas and on the surface can change with it’s concentration.)

    • gregole says:

      “…The modelling approach is inherently of no value for predicting future temperature with any calculable certainty because of the difficulty of specifying the initial conditions of a sufficiently fine grained spatio-temporal grid of a large number of variables with sufficient precision prior to multiple iterations…”

      This has always been in my mind, number one criticism of climate modeling – computer climate modeling is an exercise in futility. It is impossible to even start the model since we don’t have enough real-time climate data to capture the starting state of the atmosphere. So I’m sure modelers just guess – they must plug in some values to get the model run started.

      • Gail Combs says:

        The IPCC actually said in the Science Report in TAR:

        “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible.’ – I 2001 section 4.2.2.2 page 774

  10. bleakhouses says:

    The chart is consistent with the 100,000 year Milankovitch cycle.

  11. KTM says:

    Has anyone calculated how much bicarbonate there is dissolved in the world’s oceans, relative to the amount of CO2 in the atmosphere?

    Since CO2 dissolved in water is in equilibrium with carbonic acid/bicarbonate, I think it would be reasonable to view the oceans as both a carbon sink AND a CO2 source.

    Mankind only contributes a tiny fraction of CO2 release into the atmosphere as it is. I think putting it as a ratio to the potential CO2 reservoirs of the ocean would make it seem even more vanishingly insignificant.

    This brings up another key problem with the hockey stick graphs for CO2. They show that CO2 goes up and down through the paleo record, then they past the most recent measurement data onto it with a massive hockey stick. But how do we know that actual atmospheric CO2 levels weren’t as high or higher in the past than they are today, but the various proxies do not accurately reflect that? I have no problem with saying that variation within a proxy is a reasonable estimation of some variables, but pasting an instrumental record onto the end without knowing exactly how that would be recorded in the proxy record, or changing over time within the proxy record, is asking for trouble.

  12. David A says:

    The 180 reading at the peak of the ice advances is very serious depletion of CO2. A reading that low should be reflected in the types of plants that grow and their relative abundance. Does anybody know about this? If the plant growth does not reflect the very low readings, then perhaps the CO2 proxy record is somehow muted to below what it actually was.

    • Gail Combs says:

      David A.
      You are correct. C3 plant growth stops or slows significantly @ 200 ppm. That means no growth and NO SEEDS. One commenter at the above links mentioned that what the ice cores represent is an average of long time perids. Also CO2 does not stay put in the ice bubbles (Think about how flat soda becomes after a year in a plastic bottle.) If the entire sample is crushed and analysed the CO2 readings are much higher but that does not suit the Con men so earlier studies on ice cores using the whole sample have been pretty much ignored after 1985. Dr Jaworowski did quite a bit of work on this.

      I list a lot of links in Comment 1 above. Dr Jaworowski and Dr. Glassman did a lot of work on the subject.

      In comment 2 (actually the comment folloing that one) I list studies on plants. One open field study shows a more realistic lower limit of ~300 ppm can be deduced from readings taken 6 feet above a field study of wheat (C3). Greenhouse studies showed “…photosynthesis can be halted when CO2 concentration aproaches 200 ppm… “
