Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm

According to the 57th Japan Antarctic Research Expedition (JARE)/National Institute of Polar Research (NIPR), a daily mean atmospheric CO2 concentration value of 400.06 ppm was observed at Syowa Station, Antarctica, on May 14, 2016.

This is the first time that the CO2 concentration at Syowa Station has exceeded 400 ppm since NIPR and the Tohoku University in Japan initiated observations in 1984. In addition, the monthly mean CO2 concentration value for June 2016 reached 400.51 ppm.

CO2 is a greenhouse gas, and its atmospheric concentration is increasing owing to human activities since the Industrial Revolution. Global warming associated with the increase in atmospheric CO2 and other greenhouse gases has become a serious problem worldwide.

“The fact that an atmospheric CO2 concentration over 400 ppm was observed at Syowa implies that anthropogenic activities are definitely affecting the Antarctic region, even though Antarctica is far from the northern hemisphere where the population is concentrated,” said Daisuke Goto, an assistant professor at NIPR. CO2 has exceeded 400 ppm at many locations on Earth; however, the Antarctic was the only region where CO2 had not yet reached 400 ppm. “It is important to continue monitoring the atmospheric CO2 concentration,” Goto emphasized.

  1. Can someone please make this shirt:

    I survived Acid Rain (strikethrough)
    I survived the hole in the Ozone (strikethrough)
    I survived Y2K (strikethrough)
    I survived 400 ppm CO2

  2. “Global warming associated with the increase in atmospheric CO2 and other greenhouse gases has become a serious problem worldwide.”


    • Scientists have too spend too much time filling out grant application forms. Detracts from their modelling.

  3. CO2 is a greenhouse gas, and its atmospheric concentration is {conjectured to be} increasing owing to human activities …

    There is not one piece of data that proves this to be true.


    1. Natural sources (and sinks) of CO2 are 2 orders of magnitude greater (around 150 gigatons per year versus around 5 gigatons per year) than human CO2 emissions.

    2. The ocean surrounding the Antarctic is an enormously large source of CO2 outgassing.

    3. CO2 levels lag temperature by a quarter cycle.


    It is highly improbable that the 400 ppmv measured above was “affected” by human CO2.



    End of story.

    • Actually the southern ocean is a sink, the co2 gradient is north to south, if the southern ocean were a source then co2 would be higher in the south which it isn’t.


      • Hans
        Atmospheric transport that carries CO2 is also from the NH to the SH. It starts in May and continues through to after December. Check the thirty detailed OCO2 satellite images released in April. Then check the surface sampling stations from the low SH points all the way down to the South pole, and that will quickly dismiss any ideas that the southern oceans are sinks. Only 8 pecent of human CO2 emissions are sourced from the SH, and its spring down here also, start of land and plankton activity. Given the huge sea surface area and that the seas are very cold, I would expect that the CO2 values would go down as the atmosphere travels south to the Antarctic vortex. They dont, its a flat line = zero adsorbsion.

    • Janice,

      As usual, here we differ in opinion… As Hans Erren already said: the Southern Ocean is a big sink for CO2.
      The oceans are monitored for their CO2 pressure (pCO2) and if that is below the atmospheric CO2 pressure (pCO2 ~= ppmv), then CO2 enters the oceans or reverse. The speed of CO2 transfer is influenced by wind speed as simple diffusion of CO2 is very slow.

      As you know, cold water does dissolve much more CO2, while warm water expells CO2. That is also the case here.

      For the map with yearly averaged ocean-atmosphere and reverse fluxes, see:

      The oceans as a whole do absorb more CO2 than they release: some 3 GtC/year…

      • Ferd, not to mention the CO2 used by aquatic plant life, and in calcification for shells etc.

        To keep these ocean environments prosperous, we must try to keep feeding them plenty of CO2.

        Thankfully, China , India and many other countries know this. :-)

    • According to , radiative forcing is given by delta F = 5.35 ln(C/C0) , so when C = 2 C0 , delta F = 5.35 ln2 = 3.7 W/m^2 which the IPCC says produces 3 K warming (when feedbacks are included). Since 1850, CO2 has increased from 280 to 400 ppmv, so the forcing should be 5.35 ln(400/280) = 1.9 W/m^2, which would correspond to 3 K (1.9/3.7) = 1.55 K , which is twice the warming of 0.8 +/- 0.1 K actually measured, way outside the error bars. The recent 18-year hiatus, even as CO2 has continued to increase year-by-year, means that an appeal to a decades- or centuries-long time constant is not valid (because in that case temperatures would continue to increase, even if CO2 stopped rising). This obviously explains why all the computer models have consistently predicted temperature rises way above those actually observed. So if temperature rises caused by doubling CO2 can be no more than 1.5 K, then we would be wasting trillions of dollars trying to limit CO2 emissions to keep the resulting temperature rises to 2 K. You are right. End of story.

    • I don’t see what they are concerned about.

      The reason they have not seen this value before is that the value of CO2 ppm there has not gotten that high there before now, at least in recent memory.

      Get used to it; we have never seen a calendar date like October 25th 2016 before either, but we will survive it.


      • (( I don’t see what they are concerned about. ))
        Mainly their income, big salaries, book sales, Docudramas, movies, speaking tours.

    • Janice, I have no problems with the alarmist “saying” that man’s CO2 is increasing atmospheric CO2

      That way I can rub it in that with China, India, and many other countries will be continuing to RAPIDLY increase their fossil fuel burning for many years to come, and that there will be PLENTY of atmospheric CO2 for all the world’s plant life..

      Best of all… there is NOTHING they can do about it. :-)

      • 150ppm apparently. We are only 250ppm away from certain extinction, but 1,100ppm away from ideal plant growing conditions of 1,500ppm.

        However, we have been undone. The alarmists are heading us off at the pass by producing more ‘peer-reviewed’ papers stating that higher CO2 levels will likely be bad for plant life!

        You and I couldn’t make it up, but they do.

    • You got that right. As CO2 is more accurately called a radiative gas, it absorbs and emits IR radiation, and converts some heat energy to IR and some IR to heat constantly in daylight—it’s overall effect is a wash during the day and has no detectable effect.

      It is during the night, when there is no solar energy input, that both CO2 and water vapor (another radiative gas, more powerful and abundant than CO2) actively convert heat in the atmosphere to IR radiation, much of which is lost to space. Downwelling IR is absorbed and re-emitted by the cooling surface and eventually lost to space as well. That is why the air chills down so quickly after sunset and small breezes kick up so rapidly around the shadows of clouds on sunny days with scudding clouds.

      The global climate computer models do not have night-time, so this radiative gas cooling function is completely absent, and they have bastardized the action of these radiative gases, renaming them “greenhouse gases.”

      • … on its way to a beneficial effect.

        And any excess quantity is nicely handled by an amazingly well-designed sink …. and, ultimately, far downstream, via evaporation, puts rain in the sky and sea weed (and other green things) in the lakes and oceans.


  4. Is it true that every square inch of the earth’s surface gives off CO2 as a by-product of the munching of methane by subterranean microbes. Far more than mankind can produce. Ain’t the trees and plants lucky.

  5. If only they has used base 7 instead of base 10 they could have gotten over this number obsession back around 1985 when it crossed from 999 to 1000.

  6. Wow, 32 whole years of data. In study of the climate that represents a single data point. And what has temperature over the Antarctic done since satellite measurements started in 1979: 0.0 degrees change.

    • 32 years of data; and predictions based on that data didn’t come true. But to alarmists, every day is day one in their ongoing desire to condemn CO2 as the culprit for a natural event.

      What is it with these self-flagellating, hair-shirt sporting, manic depressives, that they are compelled to impose their demonic beliefs on the rest of us?

  7. Is North America the biggest carbon sink? Since all the leaves are gone here now, is that why C02 is up? I am pretty sure Antarctica is not a carbon sink.

  8. They should stop spooking themselves and go buy a CM-0039 1% datalogger. About $200, or a lot less from the manufacturer. Get a few sequences of the diurnal variation. Around here its about 40ppm, eg 380 – 420. Been the same for years.

    • Well done. That 400ppm isn’t just a number, it’s a very good number, and it’s getting better all the time.

    • …watch the weepy tears.

      Double CO2 and water (from the weepy tears). What happy plants we will have.

      Now if only the increase in CO2 could add a bit more warmth. Now that would be even better still. We can live in hope..

  9. Here in Colorado all the marijuana grow facilities pump CO2 into the enclosures until the concentration reaches 1500ppm. Coloradans used to worry about global warming and CO2 but since pot became legal….they don’t worry about anything any more.

    • and Peyton Manning, retired Denver Broncos quarterback and owner of many Papa John’s Pizza places, says he has sold mucho more slices since legal recreational pot in the Mile High City …

      • I haven’t even tried Papa John’s new ‘grass’ pizza. Should be a big seller though! Leaves a mellow aftertaste.

      • Hey now, Bubba Cow! Peyton was a Colts boy for far longer then he was a Bronco. And some of us still burn Jim Irsay in effigy for releasing him. >_< But at least Manning was able to win another Superbowl with the Broncos.

  10. In today’s El Tiempo, Bogota: The planet breaks the record for CO2 in the atmosphere.

    Of course they are only repeating what overseas news services repeat – Efe and AFP in this case.

    As usual there is no attempt to present any counterarguments. Luckily, I suppose Colombians have more to worry about than Global Warming.

  11. It’s a shame we didn’t evolve with 6 digits on each paw. If we had, we would count in base 12 and it would only be 294.

    • As of today, there is no problem.

      As of today, there is a net benefit.

      Will this continue to be the case as CO2 increases?

      Personally, I would say yes. And if by some happy coincidence increasing CO2 brings with it some increase in temperature, personally I would suggest that that would be a godsend; the planet is presently way too cold (we are in the 2nd coldest period in the last 500 million years) and life in general would benefit if the planet were to further warm by a few degrees.

      Of course, there would be some winners and losers, but overall, warming would be a net benefit to the biosphere.

  12. Gasp! Choke! I just reached a tipping point! Just look outside!
    Woops. It’s exactly like it was yesterday. Except four degrees Celsius cooler.
    I imagine the phenomenon of ‘a cooler day after a warmer day’ is exactly what’s predicted by the climate models.
    My problem is having to constantly put up with this nonsense.

  13. Chart from the main post.
    What I find interesting is the rise in CO2 values during December through to February, the SH summer period. Note 2014 / 15 and the the 2015/16 period.

    Also note the unusually long increase curve from March through to late September into October. This is from two sources, first the end of summer in the SH to mid May with some NH mixed in, and then the continuous flow of well mixed atmosphere from the NH that starts in May drawn by the increasing vortex. Then it goes flat until mid December. Depending on the NH winter and events occuring there, the rise over December to Febfruary is mostly from the NH.

  14. The fact that CO2 concentrations are much the same all over the World, is simply proof that the variation in CO2 concentrations in almost entirely caused by natural emanations from land and oceans. If industry was responsible for the growth of CO2, concentrations would be higher in the northern hemisphere.

    • Manmade CO2 is swamped by natural sources.

      But that does not necessarily mean that the increase in the concentration of CO2 is not a consequence of manmade emissions.

      The question to be answered is suppose man did not emit any CO2 (on an industrial scale) would present CO2 levels be less?

      • At between 2ppm and 4ppm…..are you kidding? Man’s CO2 fingerprint is only detectable because someone wants to find it. The scientific community largely condemns Homeopathic remedies which are dispensed at ppm treatments. Why should they believe in CO2 ‘forcing’ at levels comparable?

      • “Manmade CO2 is swamped by natural sources.”

        That is true Richard, but you’re omitting to mention is that natural sinks also swamp man-made ones. The difference in observed concentrations are overwhelmingly human in origin as per their isotope analysis.

    • ntesdorf
      Currently there is a higher volume of CO2 in the SH than the NH by about 15ppm average. The rise in the mid to high latitudes is almost entirely from the NH, it transports down here every year. That is why the latest OCO-2 images – 30 of released in April are not well known. They are not easy to find on the NASA OCO-2 website. You have to really search for them. No comment from NASA when they were released. They completely rebuke and make a joke of the current carbon cycle theory (the first drawings for the IPCC CAGW program were from Walt Disney !!).

      Study the images you can see them with commntary here. Ignore the commentary by all means – just look at the images. And rememeber, only 8% of human CO2 emissions are from the SH.

      After all, isnt the centre of the whole discussion CO2 ????????????????????

      • It is an interesting commentary.

        Has anyone worked out how much oxygen we are losing (consuming) from our atmosphere by burning fossil fuels?

        We are essentially replacing oxygen with CO2, CO and H2O (and other miscellaneous gases such as SO2).

      • The last time I looked, Ralph Keeling reported that Oxygen was reducing at a faster rate than can be attributed to binding in CO2 formation. The older CO2 surface station reprts had CO2 and O2 on the same chart. Some would say that the decreasing O2 levels are a greater problem long term as most of it is bound and the only freely available stuff is in the atmosphere. Note that the base level is about 20% of total atmosphereic gas. Studies have identified that O2 levels drop in heavily populated areas especially on still nites, combustion for heating, vehicle usage. So breathing problems can be a problem.
        Thanks for the comments on the article. The next one is on the way, it will focus on sea ice, atmospheric transport and a few other directly inter-related events. Sometimes you need to look at the data in a different light.

  15. There was a recent paper that claimed the greenhouse forcing over much of Antarctica was negative. It cools. I wonder why they didn’t mention this little fact.

    • Antarctica was still fairly balmy well into the Cenozoic Era. Fossil marsupials have been found there from the mid-Eocene Epoch. They probably survived at least into the Oligocene, before the ice buildup got too great.

      Antarctica of course was the bridge connecting South America with Australia, so that marsupials could spread from the Americas to Oz. When the Southern Ocean formed, with South America and Australia both separated from Antarctica by deep channels, ice sheets spread across the South Polar continent, burying prospective fossil beds.

  16. CO2 is a greenhouse gas, and its atmospheric concentration is increasing owing to human activities since the Industrial Revolution.

    We do not even know that CO2 is a greenhouse gas. It is a radiative gas, but whether it is a greenhouse gas is moot.

    Since no one has yet been able to show through observational data any signal to CO2 forcing temperatures upward, and given that the data suggest, if anything, that there is no correlation between CO2 and temperature, on any time scale, and to the extent that there are similarities (between temperature and CO2) it appears that CO2 lags temperatures, such that the data (admitted poor, uncertain and of short duration), suggests that CO2 is not a greenhouse gas.

    But as i say the jury is out, and the position is moot until we get better and more reliable data.

    • “We do not even know that CO2 is a greenhouse gas. It is a radiative gas, but whether it is a greenhouse gas is moot.”

      Sorry, did I read that right? CO2 might not be a greenhouse gas? So we have a global warming ‘theory’ based on the unproven warming properties of a ‘greenhouse’ gas, that isn’t a greenhouse gas after all?

      Where can I find (layman’s) information on radiative gases, CO2 as one, that bear scrutiny?

    • CO2 has risen monotonously since the end of WWII, but global average temperature (to the extent that it can be measured) has not. Indeed, far from it.

      GASTA fell dramatically from the ’40s to about 1977, when the PDO flipped. Despite thoroughly cooked books, the climate gatekeepers haven’t yet been able to make this decades-long chilling disappear yet. And it’s recorded in data from the time, which showed such cold that the big scare in the ’70s was the coming ice age.

      Then, from 1977 until the super El Nino of 1997-98, rising CO2 and global warming happened to coincide accidentally. From 1998 until this year, GASTA was flat to falling. The super El Nino of 2016 may have turned the slope slightly up, but it’s liable to flatten out again. In any case, the satellite observations since 1979 (and before) show warming far below that predicted by GIGO climate models.

      So the null hypothesis can’t be rejected, ie that nothing the least bit unusual has happened to global climate as a result of rising CO2 over the past 71 years.

      • Absolutely.

        I would go as far as to say, it is far from clear that today (2015/16/17) is in fact any warmer than it was in the 1940s.

        If in about 1980 one looked at the temperature record, it showed a cooling of about 0.3 to 0.5 degC between (about) 1940 and early 1970. There are even some NASA papers stating that the planet cooled by that amount. It is documented.

        If one looks at the satellite data, it suggests a warming from 1979 to date of about 0.36 to 0,42 degC. This therefore suggests the possibility that we are today back to the temperatures last seen in the 1940s.

        Further, the tree ring data that M@nn had to ignore when performing his nature trick also does not suggest that it is warmer in the mid/late 1990s than it was in the 1940s. This therefore also suggests that the temperature today could be about the same as it was around the 1940s.

        The importance of this is that if temperatures today are approximately the same as they were back in the 1940s, then notwithstanding that about 95% of all manmade emissions having taken place during this period, there has been no measurable increase in temperature over and above measurement errors/the limitation of the data that we have available to us.

        That would put Climate Sensitivity at zero or close thereto or say at a level below which it cannot be measured. As I say, whether CO2 is a greenhouse gas is a moot point.The data that we have available to us is of too poor a quality to measure and ascertain this.

  17. CO2 started to correlate with average global temperature in about 1973 and stopped correlating in about 2005. Other than that, not so much.

    Water vapor increase, combined with an approximation of ocean cycles and a proxy, which is the time-integral of sunspot number anomalies, however . . . 98% match 1895-2015.

  18. ““It is important to continue monitoring the atmospheric CO2 concentration,” Goto emphasized.”

    Bullshit. Only if one believes that a natural, valuable trace gas can affect the world, like Homeopathic medicine can’t.

    Seriously, would a millionaire be concerned about a £/$4 increase (4ppm CO2 increase) in his wealth every year, over 40 years…..It’s £/$160 for Christ sakes!…….I spend more than that on beer ever month.

    Come the revolution, the Ferrari’s mine!…….A nice bright Green one, with a 5 Litre, petrol burning, CO2 emitting, plant life stimulating, V12 engine. And woe betide any greeny, luvvy cyclist gets in my way when I’m driving down a cycle lane in central London!

    I’ll never be famous, so f**k em all. I hate PC crap, I hate cultural integration for the sake of it, I hate cyclist’s who provoke confrontation with drivers because they’re always ‘victims’. I hate runners on the street when they can go to a track, I hate effing water bottles, I hate lycra and the gym mob who express their healthy credentials by heaving their fat arses around in track pants and shorts. Have they no sodding dignity! I think Zumba/Step etc. and boom boxes are puerile, self obsessive and a complete waste of time; stop stuffing your face and you just need to walk the goddamn dog for exercise! Most of all, I hate the liberal city dwelling muppets who believe CO2 is poisonous.What planet do they come from? Seriously. But you tell them, and you tell them, and you tell them, and they continue to tell you that the planet is dying because CO2 is increasing. What effing chance do we really have in the face of abject stupidity?……….I think I should stop now, and breathe.

    Ahhhhhhhhhhhhhhhh……..better now. Until tomorrow!

  19. What will be said if atmospheric CO2 begins to decrease? Aw, I’ll answer my own question. There would be a scramble to take credit for it, and that would take many forms.

    • And of course, the world must cool if CO2 decreases because it heats up if we add it. So we get a cold planet with no plant food, effing marvelous. Like I want that for my kids!!!

    • More importantly, in my opinion, is that no matter how dismally the ‘clean’ energy, windmill and solar brigade fail in the future, they will take the credit for ‘restraining’ temperature rises, that never happened. They will spend Trillions on wind farms and bio fuels, tax people into poverty, preside over mass third poverty, enjoy their filthy lucre, and then tell us they saved the planet.

      As bad as the coal and oil barons were, they were kindergarten kids compared to the mob we are dealing with now.

      • Love the rant at 4:48pm. I think there many of us that feel the same way as apparently the mods do as well. All of us are just as frustrated with the crap that is going on and your description of the urbanites firs to a T. Thanks you got at least 1 supporter but I think there are many. Thanks for the rant, but do sit back and relax now and have that beer. Cheers!

      • I remember when I was young…..

        … a long, long time ago when the earth was a pretty cool place …

      • Oh, math professor Andy (and that is for real, not a mere compliment, WUWTers) — I messed up! Somehow (who knows) I put a decimal into that $100 and made it $1.00!! aaaaaaa. Next time, I’ll be more humble and double-check. As IF a math prof. wouldn’t get that right. **double blush**

  20. Mother Nature’s “grim milestone” seems to be as effective as Barack “Nobel Peace Prize” Obama’s red line(s) in Syria…

      • I believe its actually written “rseset”…at least, that’s what the smart people say. You know, the ones whose entire foreign policy is based on “zingers” like “the 1980s are now calling to ask for their foreign policy back because…the Cold War’s been over for 20 years.”

        Wow, what depth. What intelligence. What?

  21. The news story appears to imply that CO2 levels in antarctica have been affected by emissions elsewhere. That in turn relies on CO2 being well mixed around the globe. Or at least better mixed that I would expect.

    The Mauna Loa figures are easy to locate. Is there a central repository for CO2 levels at various places around the world?

  22. If CO2 lev ls fall below 150ppm, photosynthesis shuts down and all life on earth goes extinct…

    12,000 years ago, at the end of the last glaciation period, CO2 levels fell to 170ppm (just 20ppm from an extinction event) the lowest level since complex life evolved about 600 million years ago.

    We should be ecstatic that CO2 levels are returning to healthier levels with our help, but they’re still too low.

    A recent peer-reviewed paper (Zhu et al 2016) shows that manmade CO2 emissions have increased global greening by about 38% just since 1980 due to th positive benefits of CO2 fertilization:

    I thought both rational humans and eco-wackos wanted a greener earth…. Oh, the irony.

    All the physics and empirical evidence show ECS (warming per CO2 doubling by 2100) will be around 0.5C, which not only isn’t a problem, it’s a net benefit….

    CAGW is dead…. I can’t believe this disconfirmed hypothesis is still taken seriously.

    • “12,000 years ago, at the end of the last glaciation period, CO2 levels fell to 170ppm (just 20ppm from an extinction event) the lowest level since complex life evolved about 600 million years ago.”

      Gee, just when human civilisation exploded and took over the planet. Can’t have been all that bad after all.

      • As you no doubt know, the planet is presently in an ice age. Rather than having a fever, the planet is way too cold, as one might expect given that it is in an age.

        About 12,000 years ago was just in to the start of the present inter-glacial, the Holocene. An inter glacial, being a period of relatively short period of benign warmth within what is an ice age.

        All significant human advance has taken place during this inter-glacial, because life loves warmth and hates cold. The history of civilisation can be traced to temperature; warmer places having obtained advanced civilisation earlier than cold places. Same with technology; mesolithic/neolithic, bronze age, iron age etc are all temperature dependent.

        Unfortunately for humans (and life in general on this planet), the Holocene is probably over half way through its epoch. It will probably come to an end sometime within the next 6,000 to 14,000 years whereupon the planet with descend into the deep throes of the ice age that it is presently in. That is when we will see real climate change, and this is when there will be mass migration of humans (and other life forms) all heading nearer the tropical regions of the planet. It will be impossible to live in high northern latitudes.

    • And according to you speculation if neither you nor I were here then then no-one would be here to speculate.
      Well done Sherlock.

  23. CO2 measurements up at an Antarctic station.
    What perchance is the plot of # of personnel and fuel consumption at the station over the same time frame?
    Just dotting the i’s and crossing the t’s.

  24. It seems like the CO2 level has been busting through the 400 ppm threshold for several years now. Every time I look at the chart it shows it going vertical through the magic level. One would think it’s long since left 400 in the dust and should be pushing through 410/420 but no, it’s always just pushing through 400.

  25. That must be good as if it spreads we can expect a significant increase in the yield of corn and rice. MG

  26. I cant believe you are all so calm. This is surely a tipping point, point of no return, apocalypse, game changing thingy. I feel the urge to run around in circles, shrieking and waving my hands. Where is Tim Flannery when you need him?

  27. From early 1990s the values of both eleven-year and bicentennial components of TSI variations are decreasing at
    accelerating (at present) rate (Fig. 2), and hence a fraction of TSI absorbed by the Earth is declining at practically
    the same rate (e.g., Frhlich, 2011; Abdussamatov, 2007b, 2009a, b). Average value of TSI in the 23rd cycle was by 0.17 W/m2 less than in the 22nd cycle. Smoothed value of TSI in the minimum between the cycles 23/24 (1365.24 0.02 W/m2) was by 0.26 W/m2 and by 0.33 W/m2 less than in the minima between cycles 22/23 and
    21/22, respectively. However, forming from early 1990s long-term deficit of TSI (see Fig. 2) was not
    compensated by decrease in the emission of the Earth intrinsic thermal energy into space which practically
    remains on the same high level during 146 years due to thermal inertia of the World Ocean. Since the Sun is
    now entering a bicentennial long-term phase of low luminosity (e.g., Abdussamatov, 2004, 2005, 2007b; Penn
    and Livingston, 2010; American-astronomical-society, 2011) such energy imbalance of the system (E<0) will
    continue further for the next few 11-year cycles. As a result, the Earth as a planet will henceforward have
    negative balance (E<0) in the energy budget. This gradual consumption of solar energy accumulated by the
    World Ocean during the whole XX century will result in decrease of global temperature after 146 years because
    of a negative balance in the energy budget of the Earth. This, in its turn, will lead to the rise of Earth albedo, the
    drop of atmospheric concentration of the most important greenhouse gas water vapor, as well as of carbon
    dioxide and other gases. Let us note that water vapor absorbs ~68% of the integral power of the intrinsic
    long-wave emission of the Earth, while carbon dioxide only ~12%. As a consequence, a portion of solar
    radiation absorbed by the Earth will gradually go down together with manifestations of the greenhouse effect
    caused by the secondary feedback effects. The influence of the growing consecutive chain of such changes will
    cause additional decrease of the global temperature exceeding the effect of a bicentennial TSI decrease.

  28. No relation between the CO2 level and near record low in antarctic winter sea ice and dramatically retreating antarctic glaciers?

    Or to the current ‘lowest ever sea ice extent for the date’ we see in the arctic?

    • If CO2 is so warming, why do we re-glaciate every time it is at its highest levels?
      Lowest ever sea ice extent for the date since 1970, must be a major historic event, what a joke.

      • I don’t see your evidence we do re-glaciate in those circumstances.

        Is it really of no concern that at this point in the freezing season we are seeing such low ice extent (and its not very thick compared to recent years either)?

        And just look at the Antarctic:

  29. Antarctica is unique in another respect, multidecadal change in strength of the geomagnetic pole (location shown in blue on the map) follows change in the solar activity (inversed correlation) with details here.

  30. From the article:

    “CO2 has exceeded 400 ppm at many locations on Earth; however, the Antarctic was the only region where CO2 had not yet reached 400 ppm”

    Are they asserting that CO2 is not evenly distributed around the globe? If that’s the case then all of the ice core recordings of ancient CO2 levels are rendered meaningless. Bubbles in ice cannot be considered representative of the global atmosphere unless CO2 is considered evenly distributed.

    And if ice core sampling is rendered meaningless, can we stop actively drilling ice cores? Especially since we have tens of thousands of polar ice core samples stored in a frozen lab in Colorado.

  31. It is not strange that the CO2 would also rise at Antarctica. The strange thing is that the variation over the year gets larger and larger the far north you travel. Even at Greenland Summit you have a twofold variation relative to Mauna Loa. Despite all the CO2 mankind is making, the nature can suck it up at twice the speed half the year, and then release a part of it again the next half year. If mankind stopped all release i would believe the CO2 in the air would drop by 2ppm a year untill we starved to death.

  32. Every increase gives us a better margin against the scenario of a photosynthesis crash. At these low levels, a good bolide strike might be all it takes to incite such a crash. 1000 ppm or bust. In all seriousness, though, we will reach a point where it is not practical to increase. We are probably going to peak at around 500. Then, the long slide to true oblivion shall resume.

  33. Isn’t 400 ppm a trigger point or a point of no return. Hopefully it is because once we pass the point of no return then any further expenses incurred in the attempt of reversing it is by definition futile. The money we save can then be spent on real problems like health and education.
