Hockeysticks don’t die, they just get more corrupt

“The IPCC remains addicted to hockeysticks”

In the 6th dimension of Intergovernmental Climate Propaganda, which arrived last week, the long discredited Hockeystick is not just a sidenote, it’s the very first graph the IPCC uses in their Summary for Powerful people (the ones who make policy).

As per usual, hundreds of years of warmth has been retro-extinguished. Thousands of proxies around the world all deviated from the real temperature and non-randomly in the same direction. It’s a conspiracy I tell you! Luckily the IPCC has found scientists who can correct these simultaneous errors of proxiness which mostly they do by just tossing out the results they don’t like. They ignore whole series they don’t like, delete the years that don’t work for them, and flip that data upside down if they need to. And if that’s not enough they use trees that grow larger rings when CO2 is higher.

And when they are not deleteing data, they’re using the wrong trees. No one is even pretending anymore. They’ve done it all before and no one went to jail or even lost a job.

As Steve MacIntyre tells it the PAGES2017 data set winnowed down the thousands of proxies to their 692 favorite ones. In PAGES2019, instead of getting more data, they got less, and now there are only 257 proxies.

You might think they were the 257 longest or best proxies, but about 25% of the ones that made it through are short coral studies which often have steep rises in the last 50 years, but no information at all for the two thousand years before that, that mattered.

Hockeystick Graph, 2021.

Figure 1, IPCC 6AR. page 8 PDF

Steve McIntyre slices and dices the Zombie Hockeystick.

The IPCC AR6 Hockeystick

Although climate scientists keep telling that defects in their “hockey stick” proxy reconstructions don’t matter – that it doesn’t matter whether they use data upside down, that it doesn’t matter if they cherry pick individual series depending on whether they go up in the 20th century, that it doesn’t matter if they discard series that don’t go the “right” way (“hide the decline”), that it doesn’t matter if they used contaminated data or stripbark bristlecones, that such errors don’t matter because the hockey stick itself doesn’t matter – the IPCC remains addicted to hockey sticks: lo and behold, Figure 1a of its newly minted Summary for Policy-makers contains what else – a hockey stick diagram. If you thought Michael Mann’s hockey stick was bad, imagine a woke hockey stick by woke climate scientists. As the climate scientists say, it’s even worse that we thought.

To give the average punter an idea of just how industrial-grade the cherry picking is, McIntyre picks a random assortment of proxy histories the IPCC filtered out in order to discover the modern Hockeystick marked in Red.

The Black graphs disappeared, the blue graphs lived on, and the red line is the politically correct history of the temperature on Earth.

PAGES2017 graphs, data,

Random selection of proxies that didn’t show unprecedented global warming in PAGES 2017. The IPPC interpretation in Red.

 

Curiously, Cape Ghir (bottom right) off Morocco actually has a hockeystick, but its one of unprecedented cooling. It’s an alkenone proxy, which McIntyre describes as being good for estimating ocean temperatures, and used so often they have boilerplate formulas to convert the values into temperatures. However this is clearly wrong, the IPCC heroes know the temperatures were rising (how could it be any other way?) so they flip the graph to “discover” the warming. Up is down, black is white, you know the drill, Winston. They’ve done it before.

And a quarter of the cherries that were picked were the brief coral studies which tell us nothing about the Medieval Warm Period:

Coral Temperature Proxies

Coral Temperature Proxies

 

Hiding the decline

Since about 1960 tree rings and other proxies “diverge” from thermometers probably because tree rings are often not good thermometers, and sometimes thermometers are not good thermometers either — especially when they are put near exhaust vents from air conditioning units.

MacIntrye:

They took “hide the decline” to extremes that had never been contemplated by prior practitioners of this dark art. Rather than hiding the decline in the final product, they did so for individual trees: as explained in the underlying article, they excluded the “divergent portions” of individual trees that had temerity to have decreasing growth in recent years. Even Briffa would never have contemplated such woke radical measures.

Say hello to Divergence-free regional chronology?

“…rather than excluding divergent series altogether,

we exclude only the divergent portions of these series.

If you don’t like your data, you can delete your data.

See the bump around World War II in the top graph? It’s gone…

Deleting divergent portions of the temperature record

The warming around WWII was “divergent” from climate models and government grants. It was deleted.

The 2021 Zombie Hockeystick also includes that famous tree that responds to increasing CO2 levels by growing larger rings.

Five different PAGES2019 series use stripbark bristlecones…

By confusing cause with effect the stripbark pines are the ultimate tool to find warming at exactly the same time as CO2 rises.

      The Pages 2K datasets have been peer-reviewed, cross-checked, and validated many times by researchers all around the world. Invalidated proxies have been removed for a reason. There is no conspiracy to cook the books, it would be impossible to keep everyone (bar one) onside. All of the data is in the public domain and available for anyone to analyse, even if they don’t necessarily understand limitations within the data.

        So please point us to the reasons behind removing the 1940s warm period. If the data is validated, then there must be a valid reason to completely remove this big bump of warming from 1910 to 1940. If you recall the Tom Wigley email to Phil Jones (link below), then you’ll remember how they discussed removing this warm period back in 2009.

        http://sealevel.info/FOIA/1254108338.txt

        “If you look at the attached plot you will see that the land also shows the 1940s blip (as I’m sure you know).
        So, if we could reduce the ocean blip by, say, 0.15 degC, then this would be significant for the global mean — but we’d still have to explain the land blip.”

        Well, it looks like Dr Phil has outdone himself with the new report because the entire warming has now been removed, not just 0.15 deg C and no one has ever explained anything.

        Every global temperature reconstruction over the past 25 years has been a hockey stick for the simple reason that the observed warming over the past 100 years has been much faster than can be explained by Milankovitch or solar cycles. Group think, fraud, or incompetence has nothing to do with it.
        It is unsurprising that rejected proxies show patterns inconsistent with those that have been validated and accepted.

          MWP was warmer LIA was colder

          Nearly all the Holocene was significantly warmer than now.

          We are lucky to have climbed slightly out of the coldest period in some 10,000 years.

          Group think, fraud, and incompetence have everything to do with it.

          Its what holds the AGW scam together.

          ” has been much faster”

          lol, Was faster between 1900 and 1940 in pre-agenda-adjusted data.

          And no, there is not enough data resolution from previous times to make that “has been faster”, except as propaganda.

          Other warming periods have been just as fast and much more protracted.

          What you really mean is that the smearing of urban temperatures and the manic “mal-adjustments” of temperature once-was-data, are more rapid since the AGW scam started.

          One day you will make up a fantasy to explain how tree stumps are found under retreating glaciers, trees aged at only 1000 or so years old. A lot more warming is needed before trees grow in those now-glacial areas again.

          Exactly, its down to ocean oscillations, in and out of sync, but lets talk about what is being observed in real time. This his not in the AGW songbook.

Tom Wigley’s ClimateGate email clearly recommends tendentiously [ ” we are still left with why the blip “] erasing the 1940s blip in the land thermometer record and now they have smoothed the ” divergent” 40’s warm blip from the IPCC’s tree ring series …. This is data tampering and you are condoning it . What is it about ” we exclude only the divergent portions of the series ” that does not perturb you ?

      It’s not just the scientists, but the field itself. Calling anything that must conform to obvious propaganda ‘science’ is an embarrassment to all legitimate science.

    Easy to get a hockey stick if you select just the series that show one. By the same token we could get the MWP or the Roman warm period, just as warm or warmer than today. So the method is worthless.

    Statistical theory says you must take a RANDOM sample, because statistical reasoning is based on probability theory. This HS junk is the exact opposite of a random sample of the thousands of available proxy series.

    Picking just the data that supports a hypothesis is scientific fraud.

    Also Steve Mac says that nowhere is the actual method explained, which makes the result impossible to replicate.

      A quote by Nicola Scafetta, Professor of Oceanography and Atmospheric Physics at the University of Naples Federico II (Italy): “The possible contribution of the sun to the 20th-century global warming greatly depends on the specific solar and climatic records that are adopted for the analysis. The issue is crucial because the current claim of the IPCC that the sun has had a negligible effect on the post-industrial climate warming is only based on global circulation model predictions that are compared against climatic records, which are likely affected by non-climatic warming biases (such as those related to the urbanization), and that are produced using solar forcing functions, which are obtained with total solar irradiance records that present the smallest secular variability (while ignoring the solar studies pointing to a much larger solar variability that show also a different modulation that better correlates with the climatic ones). The consequence of such an approach is that the natural component of climate change is minimized, while the anthropogenic one is maximized. Both solar and climate scientists will find the RAA study useful and timely, as it highlights and addresses this very issue.”

          It became an issue again in the 2010s because of the mandated diesel engines in France. The move to high compression engines meant we had swapped a fixable problem with (removable) sulphur dioxide (SO2, turns into H2SO4 sulphuric in the water/rain) to NO2 (forms nitric HNO3 in the water/rain). Dictatorial Green mania in government had replaced an historic problem with a new one. So they introduced a city tax on diesels. Which is why the maillot jaune protests. Idiotic Green bureaucrats keep inventing problems, forcing people to buy diesel cars and then punishing them for doing so.

          And Volkswagen were made the villains for giving legislators what they demanded, lower pollution with zero acceleration. Green diesels. Bureaucrats saving the planet. Too bad about reality.

          This reminds me of the transfat tragedy where America legislated the swap from saturated animal fats to caring, green hydrogenized vegetable oil and pilloried McDonalds and others for not swapping fast enough. Then it became clear that transfats were lethal, carcinogenic disasters and McDonalds became heroes.

          I wonder if mandatory vaccination will produce a similar tragedy, with mandatory innoculation of young people, even children who do not need innoculation. Herd immunity is a myth, a retrospective popular explanation for why viruses die out when the real reason is a rapidly spreading benign mutation because there was never an innoculation for H1N1.

          We were told this year that we all had to be innoculated for the latest flu because a flu epidemic was likely. In fact no people have died from the latest flu mutation in Australia this year and there is no epidemic. Nor was one expected but hundreds of millions of dollars were spent. For nothing.

          What I would love is that we become more aware of the dangers of flus and other communicable diseases and bring back health checks at every point of entry, as we used to have when we still remembered the problems, the pandemics which spread so rapidly with air travel. But now we have the UN/WHO to protect us.

          But the WHO and IPCC are under the control of the United Nations, 40,000 unelected people doing the work of the 75% of world governments which are military dictatorships. And still pushing an utterly discredited Hockey stick as if it had any relationship to reality. Meanwhile Tedros Adhonom has not said sorry for telling the world with all his authority that Wuhan Flu was not infectious, ‘person to person’. He lied. He and his friends and President Xi and his generals should all be on trial for crimes against humanity. 4 million dead and no one is saying sorry. He did however rename it to avoid the China military weapon connection, which has always been so obvious. Wuhan flu was released in exactly the way any country would launch WWIII. Unfortunately for Xi, Trump and Johnson survived.

          Hockey sticks and world pandemics, brought to you by the UN. At your expense in every way. Plus acid rain, again.

A mixture of garlic from the restaurants and the smell of a small number of ULP cars in town … from 15 km away.

            My real concern with acid rain was not the fish in America’s lakes, as debunked later by David Maddison but the mass destruction of our heritage, so many beautiful buildings made from limestone (London, Paris, Odessa). Westminster Abbey is one. In Melbourne, much of the ornate sandstone of St. Paul’s Cathedral had to be completely replaced in the 1990s. Older structures such as 900 year old Norman Gothic Cathedrals are just ruined. The faces go missing first.

            The environmental concern is quite fake. Acidity at this level is nothing to wildlife. Humans drink Coca Cola and do not vanish. The dying fish from carbon dioxide is debunked as well and the JCU business Dr. Phillip Munday and students with carbonic acid from Ocean Acidicification has proven to be fake research. But JCU says he has left. And they found no fault with his research. Where Ridd was obviously fired for spilling the beans.

            However the beautiful sandstone and limestone and marble buildings fall apart in a few decades. And that is a real loss to everyone. Nothing to do with fish and the environment. And the concrete pipes do not appreciate acidic water either and tend to make it basic, at a loss to the concrete.

          All rain is acidic to a greater or lesser degree depending on the constituents of the atmosphere it falls through.

          What was labelled “acid rain” had much higher than normal levels of sulphur and nitric compounds (sulphuric and nitric acids which are not particularly friendly to life forms) dissolved in it.

          Volcanic action causes highly acidic rain from the release of sulphur. The problems caused by these are temporary. There was a certain reason behind the Green idea of banning sulphur but it was fatally flawed and totally stupid: there is no way we can prevent or control volcanoes. They happen.

            There was a major problem with Venezuelan oil. It was very high in sulphur. You could tell which countries were using it from the stench.

            But sulphur is now extracted and Venezuela has the biggest oil supplies in the world, which is why it is Socialist, the people are broke, government gangs and foreign soldiers control the country and the Chinese and the Russians and the Cubans are all in there helping their comrades take the oil while the people lack power, petrol, hygiene, jobs and it has gone from a first world country to a third world country in a few years. Socialism, it turns first world countries into third world countries overnight.

        DR WILLIAM REVILLE UNDER THE MICROSCOPE

        Whatever happened to acid rain? Back in the 1970s and 1980s it was killing our forests, acidifying lakes so they could no longer support life, and leaching metals out of soil into waterways where they could attack human health. Feelings ran high.

        In 1993, John Gummer, UK secretary for the environment was called a drittsekk (“sack of sh1t”) by Thorbjorn Bernsten, Gummer’s Norwegian counterpart, for failing to take air pollution seriously.

        Nowadays we don’t hear of acid rain. Have we solved the problem, and how big was it anyway? The answer to the first question seems to be a qualified yes, and to the second – not very big.

        Acid rain was mainly caused by emissions of sulphur dioxide to the atmosphere from coal-fired power stations, and by emissions of oxides of nitrogen from various sources. These gases, combined with water in the atmosphere to form sulphuric and nitric acids. The acids fell to earth as acid rain and studies purported to show acid rain damaged trees, polluted streams, lakes and rivers and damaged wildlife and buildings. It was estimated that 4,000 lakes in Sweden were acidified to the extent that no fish could survive and thousands of lakes in America were likewise “killed”. In the UK, acid rain was blamed for destroying toads and for eroding the structure of important buildings.

        Acid rain was dealt with in the 1980s and 1990s. By switching from coal to gas and installing “scrubbers” to clean up power station and factory emissions, huge reductions were made in acid rain pollution in Europe. Catalytic convertors on car exhausts reduced nitrogen oxide emissions. The US Clean Air Act Amendments, designed in part to control sulphur dioxide emissions, were passed in 1990.

        Emissions of sulphur dioxide and nitrogen oxides are now under control in Europe and America generally, but emissions from shipping still cause acid rain in coastal areas. Some experts warn that increasing acidity of the oceans could destroy all coral by 2065. Also, acid rain persists in China, which now burns half of all coal burned in the world annually.

        How dangerous was acid rain? The most comprehensive study was commissioned in 1980 by US president Jimmy Carter. The National Acid Precipitation Assessment Programme (NAPAP) examined the damage caused by acid rain and recommended solutions. In 1982 president Ronald Regan raised the annual budget for NAPAP to $100 million. The final cost of NAPAP, the most costly environmental study in US history, was $537 million.

        The situation turned out to be much more complex than had been predicted. The acidity of a lake is determined as much by the acidity of the local soil and vegetation as it is by acid rain. Many lakes in north-eastern America, dead in the 1980s, had plenty of fish in 1900. It was surmised by environmentalists that 20th-century sulphur dioxide emissions had choked these lakes to death with acid rain. But the NAPAP showed many of these lakes were acidic and fishless even before European settlement in America. Fish survived better in these lakes around 1900 because of extensive slash and burn logging in the area. The soil became more alkaline as the acid vegetation was removed, reducing the acid flowing into the lakes and making the water hospitable to fish. Logging stopped in 1915, acid soils and vegetation returned and the lakes became acidic again. The study also found that in many cases forests were suffering debilitation due to insects or drought and not acid rain.

        The NAPAP reported in 1990. The findings were explosive: first, acid rain had not injured forests or crops in US or Canada; second, acid rain had no observable effect on human health; third, only a small number of lakes had been acidified by acid rain and these could be rehabilitated by adding lime to the water. In summary, acid rain was a nuisance, not a catastrophe.

        Yes, tree rings are most affected by water stress. Small rings if hot and dry OR cold and dry. Large rings if warm and wet and mild (within limits) and wet. Tree rings tell you the available moisture at the time more than anything about temps. A grape vine will grow faster at 20c with lots of water than at 30c with inadequate water. Plant rings are hopeless as proxies for temps.

      I do not recall the name, but about five years ago (give or take), a young lady botanist would post on an irregular basis over at Anthony’s. She got into several discussions about tree rings, and related subjects, so at one point, I asked her point-blank, “Are tree rings usable proxies for temperature?”

      Her answer could not have been more succinct: She said, “No.”

      There were very few posts after that, and then finally, she left the forum.

      And, yes, she professed a belief in AGW and CAGW. Not a friend of Anthony’s, or Jo’s, or of mine.

      I promise, that was her entire post, viz. “No.” No elaboration, no discussion, no nothing. Just, “No.”

    The physics of the atmosphere would dictate that energy absorbed by CO2 is thermalised to the remaining 99.96% of he atmosphere, and dealt with by the normal process of the pressure driven lapse rate.

    Recent data shows this conclusively to be correct.

    Increased CO2 does not retain energy in the atmosphere.

    Data proves that while there is a decrease of OLR in the narrow CO2 band, as expected, it is more than compensated by an increase in a much wider band of OLR in the atmospheric window.

    The absorbed energy in the CO2 band is being thermalised to the rest of the atmosphere and rejected at a different frequency, exactly as atmospheric physics controlled by the gravity based lapse rate would dictate.

    https://i.postimg.cc/FRtCjkyG/Radiative-change.jpg

    OLR is increasing, in line with atmospheric temperatures

    https://i.postimg.cc/76VcwYzV/OLR-increase.jpg

    The only way this can happen is if the energy causing the mild but highly beneficial warming is from an exterior source.

    This is actually that big hot shiny object in the sky, which we call The Sun, but also affected by a decrease in cloud cover over the tropical oceans, thus helping fuel the El Nino events that are the coincident with the only warming since 1979 in the satellite temperature data.

    https://www.climate4you.com/images/HadCRUT3%20and%20TropicalCloudCoverISCCP.gif

    Also if we look at Solar intensity, we see that we have just had a period of the highest solar activity in a very long time.

    https://upload.wikimedia.org/wikipedia/commons/6/60/Solar_Activity_Proxies.png

    New paper also shows that if you use unadulterated data, solar energy is responsible for all the
    small but totally beneficial temperature rise in the last 150 or so years

      Nicely put.
      Particularly liked the material about the “lost” energy in the associated CO2 emission frequency being accounted for in the rest of the IR spectrum and presumably at a lower, less intense frequency.

      PW IR in the upper atmosphere has only one place to go on its slide down the energy gradient; deep space.

      Good, but “helping fuel the El Nino events” is not likely. The huge heat sinks on the planet, the ones which control and generates and change our weather are the oceans. As I always point out, with 340x the mass and 1400x the heat capacity of the air, the ocean temperature and specifically the ocean surface temperature generates ALL our weather. There would be no weather without water, just dust storms on a dead planet.

      But the ocean oscillations (PDO, AMO, ..) are not just on the surface or in swirling patterns horizontally or 2D but also 3D as currents hit continents and bounce upwards or sink. Oceans are up to 7km deep! Welling up of even slightly colder or warmer water from below can be a slow process, but likely to be a consequence of big oscillations, like a swimming pool on a boat in a storm (always fun and amazing).

      Until the vaunted Hockey stick computer models include the massive and dominant amount of energy in the oceans and the incident solar energy, they always will be wrong.

      Otherwise all the Hockey Stick predictions are based on the 0.1% of the solar energy stored in the tiny atmospheric system. How anyone thinks such a model will work at all for long term climate predictions is beyond reason. As I point out so often, Professor Weiss’ mathematical analysis was perfect, a fit for the last 250 years. And he only needed one solar cycle (De Vries 260 years) and the AMO/PDO to get a perfect fit. CO2 is irrelevant.

      But this comment is about the idea that the incident energy creates or alters El Nino cycles or any of the other big ocean oscillations. I would be surprised. The oceans hold tens of thousands of years of radiant solar energy and never freeze as they moderate climates all over the planet. And if one of them should actually change, say the Gulf Stream, it would be a disaster, but it is also very unlikely. Homo Sapiens has not been on the planet long in geological terms to be so unlucky.

      If we all drive Teslas, rely on windmills and solar panels though, we are told climates will never change and we will have no bushfires in Australia, Greece, California, Russia, no hurricanes or tropical storms or tidal waves or volcanoes. How reassuring is that? Looked at that way, Teslas are a bargain.

    An interesting recent comment from Roger Pielke Snr at Judith Curry’s blog and his link. He is referring to IPCC AR6 and he provides a link .
    The period he refers to is 3.5 decades ( 1979 to 2014) and that would be an extra warming of 0.35 c ( at least ) over that time. Or perhaps another 1.0 c of make believe warming in the next 100 years?

    So is Dr Pielke correct? And has anyone here have any comments? Over to Dr Pielke Snr.

    “Roger Pielke Sr | August 10, 2021 at 9:55 am | Reply

    “we assess with medium confidence that CMIP5 and CMIP6 models continue to overestimate observed warming in the upper tropical troposphere over the 1979-2014 period by at least 0.1°C per decade, in part because of an overestimate of the tropical SST trend pattern over this period.”

      The energy uptake of the oceans is limited by an ocean surface thermostatic process that results from the formation of ice above 7000m in the atmosphere. That process is observed as monsoon, which can develop into tropical cyclones at latitudes greater than 10 degrees. Monsoon cloud limit ocean surface temperature to an annual average of 30C and short term peak of 32C.

      The loss of ocean heat is limited by an ocean surface thermostatic process causing the formation of sea ice at -2C. Sea ice is highly insulating and results in a dramatic reduction in heat loss once the sea ice forms. The temperature of the water interface below a thin layer of sea ice is -2C.

      The two temperature limits are observable any day of any year for the past 50M years since the surface pressure has been close to what it is today:
      https://www.tropicaltidbits.com/analysis/ocean/cdas-sflux_sst_global_1.png

      The addition of CO2 does not alter the surface pressure so cannot alter the upper ocean temperature limit. It depends entirely on the behaviour of water (liquid, solid and gas) in the atmosphere:
      http://www.bomwatch.com.au/wp-content/uploads/2021/08/Bomwatch-Willoughby-Main-article-FINAL.pdf

      Temperature measurement of the troposphere are likely to show some influence from CO2 but that is unrelated to ocean surface temperature and the global energy balance because they are functions of precise thermostatic processes. I believe the trend in the UAH TLT data set shows a CO2 signature.

      If “the science” of global warming was settled, the IPCC could have stopped at the First Assessment Report and made a 4 page summary each year showing how well the models predicted the current situation. Such a comparison would show how poor the models are. Instead IPCC AR6 is a 4000 page pile of manure. Any journalist reporting on the IPCC should be asked a simple question – have you read the report? If they had they would know it is layer-upon-layer of manure.

      What is not stated in any IPCC report is that Earth’s orbit is constantly changing. There are significant orbital changes year-to-year and longer trends. The Southern Hemisphere has been getting less sunlight for the last 400 years and the Northern Hemisphere more sunlight. But there are seasonal changes as well. For example, Sydney is getting 1.2W/sq.m less in October now than in 1850 but 1W/sq.m more in March. The change since 1850 in New York is 0.6W/sq.m more in March but 0.6W/sq.m less in August.

      The climate is ever changing but literally NOTHING to do with CO2 as an atmospheric gas.

        You’ve got to ask why anyone is listening to the IPCC anymore? They have been wrong about everything since their first assessment report in 1991. And in 1991 they were predicting a 1 meter rise by 2100, but by 1993 they has moved it up to 1.1 meters rise by 2100. Just 2 more years on and it varied towards the hysterical end by another 10 cm! What a clown show.

          When the UN/IPCC says the planet is burning and Wuhan Flu is not infectious, people believe them. There is no science. It is just lies by the communists who run the place.

            And you get our communist leader, Generalissimo Danial Andrews who legislated his own private army to arrest people indefinitely without warrant or any judicial oversight. It actually passed our parliament to be made law but was stopped by two Green votes in the upper House. And it takes a lot to get the Greens to stop anything, but he nearly had his own private army under his command. It happened in 1933 in Berlin too. Fascism was socialism.

            Even now Andrews has the whole city of 5 million in a 9 to 5am curfew! For our own safety.

            Why? Because he can. And no medical person can explain the curfew, nor the police.

            And the Victorian police are supposed to arrest children and parents if they dare go near a playground on the weekend, masks or no masks.

            This is the man who signed ‘his’ state up to the Chinese Communist Belt and Road deal in a private deal, even though under the Federal Constitution has no such power to make international agreements of any sort. And I would be arrested by his storm troopers and disappeared forever, except for two Green votes. It’s that bad.

            So while we puzzle over the amazingly in your face criminal rehabilitation of the utterly discredited hockey stick, remember some people believe that everyone in power means well. Not Daniel Andrews and not their UN/IPCC/WHO. I am counting 4 million dead from the WHO lies alone. And their rich ABC says nothing, because the idi*ts are part of the problem.

    This is the crucial period for the totalitarian movement. It needs to negate the old “reality” in order to implement the new one, and it cannot do that with reason and facts, so it has to do it with fear and brute force. It needs to terrorise the majority of society into a state of mindless mass hysteria that can be turned against those resisting the new “reality.” It is not a matter of persuading or convincing people to accept the new “reality.” It’s more like how you drive a herd of cattle. You scare them enough to get them moving, then you steer them wherever you want them to go. The cattle do not know or understand where they are going. They are simply reacting to a physical stimulus. Facts and reason have nothing to do with it.

    Here’s their conclusion and the link.

    https://judithcurry.com/2021/08/17/new-confirmation-that-climate-models-overstate-atmospheric-warming-2/

    “Concluding remarks

    “I get it that modeling the climate is incredibly difficult, and no one faults the scientific community for finding it a tough problem to solve. But we are all living with the consequences of climate modelers stubbornly using generation after generation of models that exhibit too much surface and tropospheric warming, in addition to running grossly exaggerated forcing scenarios (e.g. RCP8.5). Back in 2005 in the first report of the then-new US Climate Change Science Program, Karl et al. pointed to the exaggerated warming in the tropical troposphere as a “potentially serious inconsistency.” But rather than fixing it since then, modelers have made it worse. Mitchell et al. note that in addition to the wrong warming trends themselves, the biases have broader implications because “atmospheric circulation trends depend on latitudinal temperature gradients.” In other words when the models get the tropical troposphere wrong, it drives potential errors in many other features of the model atmosphere. Even if the original problem was confined to excess warming in the tropical mid-troposphere, it has now expanded into a more pervasive warm bias throughout the global troposphere.

    If the discrepancies in the troposphere were evenly split across models between excess warming and cooling we could chalk it up to noise and uncertainty. But that is not the case: it’s all excess warming. CMIP5 models warmed too much over the sea surface and too much in the tropical troposphere. Now the CMIP6 models warm too much throughout the global lower- and mid-troposphere. That’s bias, not uncertainty, and until the modeling community finds a way to fix it, the economics and policy making communities are justified in assuming future warming projections are overstated, potentially by a great deal depending on the model”.

    CNN and the rest of the LW MSM in the US hate FOX News with a vengeance.
    If only McIntyre, Christy, McKitrick, Curry, etc could get some air time there this could still blow up and become a festering sore for their AR6 report.
    The seeds of doubt need to be planted early in the public’s mind. I’m sure Andrew Bolt and Rowan Dean will take this up soon, but I could be wrong and Sky News coverage would be great but not the same seismic shift as FOX News coverage.

    “sometimes thermometers are not good thermometers either — especially when they are put near exhaust vents from air conditioning units.”

    if the aircon units are split system, the thermometers near such air con units work both ways. In summer the unit exhausts the hot air from the room and in winter the air con unit exhausts the cold air from the room so a thermometer near the exhaust vent will show as hotter in summer and colder in winter.

    Sometimes methinks her agenda is to lock everyone indoors so they can’t see (with their own eyes) the YUGE SNOWFALLS burying the Southern Alps and Mount Ruapehu. Big, cold snow on the way this weekend for TAS, Vic, NSW, and maybe even southern Queensland, again.

        You need to get on message – July 2021 was the warmest EVAH. That is what was reported during our nightly weather forecast in Melbourne yesterday. But then went on to show chilly wind over the bay suggesting today would also not be good beach weather.

        July 2021 has been identified as the warmest month since records began, not “ever”. And via the same data, the ten warmest years have occurred in the last 16 years.

        (Note: at this point I do not need the stock responses that NOAA is as corrupt as their data – and anyway – to reject inconvenient data is just what the IPCC crew are being attacked for in today’s post).

        My main concern with the arguments put here, is the obsession with data, almost to the exclusion of everything else. You almost literally only have to look around you, at the shrinking Arctic sea ice, the permafrost melt, temperature records being set in many places, fierce floods and wildfires, sea-level rise, and much else.

        Just one example – the dramatic and close to catastrophic decline in the water volume of the Colorado River, resulting from much-reduced snowpack in the Rocky Mountains. Tens of millions of people rely on a river that simply cannot deliver any more.

        I remain sceptical of those who are sceptical about the IPCC figures. If it’s a dodge that means there are an awful lot of scientists who are being fraudulent … it’s very difficult to accept.

        I have no doubt the planet is getting hotter – and reasonably rapidly too – within the scale of a century or so, or even just one long human lifetime. Weather events such as snow in NZ or on Cradle Mountain, or a cool breeze across Port Philip Bay, are not contradictory evidence … it’s just wintry weather.

        The challenge is, what to do about it. in a sensible timely way, before we are forced into even worse choices. Personally I would like to see us wind back the hyper-complexity, hyper-materialist, and hyper-consumerist mad world we’ve created – or had imposed upon us.

        I’m not saying we all have to head back to the garden like well-behaved hippies, but simplifying things would be a good start.

        When you see mindless people queue all night, just for the privilege of handing over huge sums just to get the “latest” iPhone, then you do shake you head in wonder …

          So Funny. Talk about denial. !

          Then ten warm years, so what… not caused by anything humans have done, just luck.

          Be very thankful for those 10 warmer years. Barely a bump above the coldest period in 10,000 years. I bet you choose to live somewhere that has nice warm summers and mild winters. Most people in the world do.

          You do know that there is massive evidence that California has had much longer droughts in the not too distant past, and that they waste lots of that water from their dams to save a fish that hasn’t been seen for ages. Are you ignorant of that as well?

          Yes we know cold is just “weather” and warm is a signal of catastrophe… that’s the AGW mantra

          You are still totally bereft of any evidence of CO2 causing warming.

          Are you aware,

          That the “snowpack” you refer to has been melting for the last 17,000 years?

          The other significant factor, that your tragically childish “science” doesn’t appreciate, is that the rate of meltdown has been lower over the last 7,000 years and this has led to an extension of the time that running water has been available.

          The South pole, by contrast has been packing on ice and saving it for a rainy day, so to speak.

            Yes – I’m well aware that the world is in an interglacial period, and that in fact all of human civilisation has occurred and is occurring within one.

            But it seems it is always brought up as an “argument” when others wish to address global warming that is occurring on a much smaller scale, brought about by industrialisation, and the rapid release of carbon dioxide. I don’t think the long-term climate patterns add to this discussion.

            Rapid Arctic sea-ice shrinking, large-scale permafrost thaw, and receding glaciers – these (and many other indicators) are much more important.

              WRONG as always, just suppositional BS backed by absolutely nothing.

              Arctic sea ice is far above what it has been for most of the last 10,000 years.

              LIA and late 1970’s were the anomaly in extreme high levels of sea ice

              Current levels aren’t even down to MWP yet.

              Receding glacier, that didn’t even exist in the MWP, exposing tree stumps some 800-100 years old.

              “I don’t think the long-term climate patterns add to this discussion.”

              Yes, you have to ignore climate history to remain in your AGW fantasy bubble.

              But its totally unrelated to anything resembling actual science.

              It will have to get a lot warmer than now for trees to grow where they used to grow.

              And of course, there is absolutely no evidence of warming caused by human CO2

    https://wattsupwiththat.com/2021/08/17/climate-hype-hurts-the-environment-and-undermines-our-society/

    Summary
    “An apocalyptic future looms before us, but it has little to do with increasing greenhouse gases.
    A future with catastrophically burning forests, of media providing increasingly apocalyptic warnings, of polluted coastal areas and poisoned shorelines, weakened democracy, attenuated and undermined science, omnipresent fear of the future, increasing power blackouts, and decreased equity in society.
    But we do not have to have this future.
    But to do so will require that we honor diversity of viewpoint and refrain from demonizing folks with different ideas or political backgrounds. That we stop politicizing science and use the best science to guide our adaptation and mitigation activities. That we stop pushing a false apocalyptic vision to encourage the “unanointed” to do the right thing. That we support technological research and considering the value of nuclear power as part of the energy mix. And that the media, such as KNKX and the Seattle Times, move from advocacy to providing coverage that is both factually correct and representative of the diversity of ideas in the real world.
    I am convinced that global warming is a technical problem that will be solved with technical innovation. And that using it as a wedge issue to promote political and ideological goals will not only fail, but undermines our society in profound ways”.

          Most of the Permafrost melted away thousands of years ago, it used to be down to around 42 degrees North which is in mid europe.

          Arctic summer ice has been little to zero for centuries at a time in the early interglacial period, Polar Bears are still with us anyway.

          Glaciers retreat is to be expected when it grew a lot during the LIA, now it has been warming for the last 3 centuries. Glacier bay was fully filled in 1760 sticking out into the pacific ocean, melted out in just 100 years time.

          It was much warmer 6,-8,000 years ago yet here we are.

          Arctic sea ice is far higher than it has been for most of the last 10,000 years.

          The late 1970s was a period of extreme sea ice extent, up there with the extents during the LIA.. That was the anomaly, current levels are only partly returned to the Holocene norm.

          Were you ignorant of that, like you are of everything else?

          Glacial retreat often reveals tree stumps and human artifacts, around 1000 or so years old.

          Please explain how those trees grew there.

          Record high temperatures.. lol.. mostly in heavily urbanised areas with substandard or unfit for purpose instrumentation.

          Did you know that the recent so-called record in Spain was in a badly weathered grey screen with no door on it,.. Seriously.. how much worse can surface data get !

          Hot records by a tiny fraction of a degree in urban areas with fast reaction time instruments, surrounded by asphalt and sheds etc.. a joke., ..

          … whereas a lot of recent cold records have been by whole degree values.

          It will need significant extra warming for trees to grow again where those tree stumps have been found.

          Many of those glaciers didn’t even exist in MWP times, they are the product of the LIA.

          The world has, very thankfully, warmed small amount of that coldest period in 10,000 years

          All your comments about climate are based on a total ignorance of climate history.

          Yet you still haven’t produce one single bit of scientific evidence of human CO2 causation.

          Why is that… ?

          CO2 warming only exists in climate models.

          There is zero evidence of it in reality.

          Still waiting for you to prove otherwise.

          Increased CO2 does not retain energy in the atmosphere.

          Data proves that while there is a decrease of OLR in the narrow CO2 band, as expected, it is more than compensated by an increase in a much wider band of OLR in the atmospheric window.

          Now read the actual science in comment #9 above

    One of the flaws of this site is that it is impossible to find comments made in previous posts without actually going into each one and searching.

    I was intending to repost a comment I made (with a link) concerning how the people creating the models for the IPCC warned that they would forecast excessively high temperature increases because the guesses they made for the effects of cloud cover were incorrect. They warned that the extreme cases should not used in the 6th Report but the IPCC put them front and center in their presentation, anyway.

    30

    • #
      Analitik

      Oh well, I found the source article that I based my previous comment on so let’s start again

      Many of the world’s leading models are now projecting warming rates that most scientists, including the modelmakers themselves, believe are implausibly fast.

      Even Gavin Schmidt had to admit they got things wrong

      In advance of the U.N. report, scientists have scrambled to understand what went wrong and how to turn the models, which in other respects are more powerful and trustworthy than their predecessors, into useful guidance for policymakers. “It’s become clear over the last year or so that we can’t avoid this,” says Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies.

      So they admit that the and behaviour and hence effect of clouds is guessed at and shoved into the models

      To find out why, modelers probed the guts of the simulations, focusing on their representation of clouds, long the wild card of climate change. The models can’t simulate clouds directly, so they rely on known physics and observations to estimate cloud properties and behavior

      And the recommendation to the IPCC was to ignore the extreme end of the forecasted temperature rises

      For now, policymakers and other researchers need to avoid putting too much stock in the unconstrained extreme warming the latest models predict, says Claudia Tebaldi, a climate scientist at Pacific Northwest National Laboratory and one of the leaders of CMIP’s climate projections.

      https://www.sciencemag.org/news/2021/07/un-climate-panel-confronts-implausibly-hot-forecasts-future-warming

      Of course they IPCC didn’t pay any attention to the scientists who were honest enough to find issues with their own work.

    It’s a plot of the SST from the Hadley Centre going from v2 to v3. Best looked at with a 12 month moving mean. Red and Blue are the northern hemisphere while green and magenta are the southern.

    Everybody makes mistakes, but science is the art of realising that you are wrong. A large number of scientists worked (supposedly) on what was a reconstruction of the data set that you needed to get a global average, from a record not fit for purpose. The checking so as to not introduce an artificial trend must have been extremely thorough. No?

    Swapping them back so that they match up, and you see another issue that screams ‘botched job’. These are averages of anomalies – the average for a particular month of a year minus the average for the same month in all the years of the base period from 1961 to 1990. As you can see, there were large changes to the beginning of the base period but little deviation either side of it.

    Then you have how all of them line up around the time of the 1998 El Nino.
    https://woodfortrees.org/graph/hadsst2nh/from:1990/mean:12/plot/hadsst2sh/from:1990/mean:12/plot/hadsst3nh/from:1990/mean:12/plot/hadsst3sh/from:1990/mean:12
    Looks more like the reference period for the reconstruction.

    And lastly, without the 12 month moving mean
    https://woodfortrees.org/graph/hadsst2sh/from:1990/plot/hadsst3nh/from:1990
    The SH v2 and NHv3 suddenly get a seasonal signal in the anomalies, and because it’s only the difference from the average of the same month in the base period, it shouldn’t be there. Oops. Start again, except it’s there again in version 3 (although now north, colours are changed on the plot so check the legend)

    And for some strange reason, I have to accept this as robust science or some Swedish teenager will huff and puff.

      Back in 1900 there were two guys in a rowing boat going offshore from Falmouth to get the daily SST – known as the Falmouth duo. It is quite reasonable to think that there are more than a single daily reading now but does it matter when making comparisons back to 1900.

      Making any claim about SST going back to 1900 with the present is so far fetched it is riduluous and deserves ridicule. I don’t care what the colours are, the basis of the temperature reading is pure nonsense. No way the Falmouth duo got down to 60S to get SST readings amongst the icebergs.

      The BoM do not even trust land temperatures before 1920 and they are far more reliable than readings from the Falmouth duo.

      Climate models are magic with regard precipitation and evaporation. The modellers do not bother with trivia like mass balance.

      I integrated the precipitation minus evaporation for the mean of the CMIP5 and found the atmosphere was magically creating water after 3 years. For year-to-year mass balance, the sum of the pie curve should be near zero:
      http://climexp.knmi.nl/data/icmip5_pme_Amon_modmean_rcp45to85_0-360E_-90-90N_n_+++_2015:2020.png
      It is clear in the plot that precipitation dominates so the atmosphere runs dry after three years. They have more precipitation than evaporation every year – magic.

      Climate models are a sad joke on society. The cretins who play with them are so far removed from reality it beggars belief.

Instead of working a lifetime to maybe find an answer to a puzzling question, the brilliance of the new science is, one knows the answer and simply by homogenisation and a bit of poetic license along the way, one simply finds the data – any data – to suit the answer. That’s the reverse of the slow old system, and so much more productive, and the data proves the argument! Doesn’t it? Instead of risking a lifetime of hard yakka, and finding no result, the new methodology is guaranteed to suit the answer at least every 5 years.

    It is really a brilliant system that no disbeliever can ever question, because every non professional person knows it is precise and right. The data says so! Time shouldn’t be wasted listening to those believing any alternative.

    “The science” is quite distinct from science.

    “The science” is a phrase that should always make you pay extra attention to the intent of the message rather than the message itself.

    Is the IPCC AR6 report statistically flawed and have so much of the previous 20 years of IPCC reports suffered from the same problems. Here’s a new essay by Ross McKitrick and an early part of the essay.

    “The IPCC’s attribution methodology is fundamentally flawed
    Posted on August 18, 2021 by curryja | 1 Comment

    by Ross McKitrick

    “One day after the IPCC released the AR6 I published a paper in Climate Dynamics showing that their “Optimal Fingerprinting” methodology on which they have long relied for attributing climate change to greenhouse gases is seriously flawed and its results are unreliable and largely meaningless. Some of the errors would be obvious to anyone trained in regression analysis, and the fact that they went unnoticed for 20 years despite the method being so heavily used does not reflect well on climatology as an empirical discipline.

    My paper is a critique of “Checking for model consistency in optimal fingerprinting” by Myles Allen and Simon Tett, which was published in Climate Dynamics in 1999 and to which I refer as AT99. Their attribution methodology was instantly embraced and promoted by the IPCC in the 2001 Third Assessment Report (coincident with their embrace and promotion of the Mann hockey stick). The IPCC promotion continues today: see AR6 Section 3.2.1. It has been used in dozens and possibly hundreds of studies over the years”.

    It is time to review those peers,
    Who concur with the unfounded fears,
    Of the I.P.C.C.,
    As they nod and agree,
    And have done for the last thirty years.

    I spotted a comment about clean air the other day in another blog and started to think on it and expand its relevance.
    Basically, the hockey stick correlates quite easily to the period when CFCs were banned and when catalytic converters arrived and when diesel engines became a whole lot cleaner.
    Could it just be that the atmosphere just got a whole lot cleaner so that much of the Sun’s radiance was NOT bounced back to space?
    True or not I am going to use to annoy climastrologers who can’t deny my theory while at the same time cannot explain the hockey stick – except for CO2.

    Remember that the IPCC has nothing to do with climate change, only with the spreading of global socialism. These bozos must be desperate if they are pushing the Mann “hockey stick” scenario again. The unfortunate thing is that gullible governments (eg; Australia) are throwing $$$ at these snout-dipping pigs.
