OAA published its global climate report for year end 2021 highlighting that its global temperature anomaly measurements showed 2021 being the sixth highest of its recorded measurements. NOAA’s global annual measurement for 2021 was 0.84 degrees C.
NOAA chose to emphasize that the annual 2021 temperature anomaly was in the top ten of its recorded years as follows:
“The year culminated as the sixth warmest year on record for the globe with a temperature that was 0.84°C (1.51°F) above the 20th century average. The years 2013–2021 all rank among the ten warmest years on record.”
What NOAA failed to highlight was that the year-end 2021 global temperature anomaly measurement marked the continuing decline of its global temperature anomaly measurements that have now fallen for the last 6 years since peak year 2016 as shown in their graph below. These declining measurement outcomes make a complete mockery of recent climate alarmists scientifically unsupported politically contrived “climate emergency” propaganda claims.

After 1750 and the onset of the industrial revolution, the anthropogenic fossil component and the non-fossil component in the total atmospheric CO2 concentration, C(t), began to increase. Despite the lack of knowledge of these two components, claims that all or most of the increase in C(t)since 1800 has been due to the anthropogenic fossil component have continued since they began in 1960 with “Keeling Curve: Increase in CO2from burning fossil fuel.” Data and plots of annual anthropogenic fossil CO2 emissions and concentrations, C(t), published by the Energy Information Administration, are expanded in this paper. Additions include annual mean values in 1750 through 2018 of the 14C specific activity, concentrations of the two components, and their changes from values in 1750. The specific activity of 14C in the atmosphere gets reduced by a dilution effect when fossil CO2, which is devoid of 14C, enters the atmosphere. We have used the results of this effect to quantify the two components. All results covering the period from 1750 through 2018 are listed in a table and plotted in figures. These results negate claims that the increase in C(t) since 1800 has been dominated by the increase of the anthropogenic fossil component. We determined that in 2018, atmospheric anthropogenic fossil CO2 represented 23% of the total emissions since 1750 with the remaining 77% in the exchange reservoirs. Our results show that the percentage of the total CO2 due to the use of fossil fuels from 1750 to 2018 increased from 0% in 1750 to 12% in 2018, much too low to be the cause of global warming.

Globally, the deviation of the global mean temperature of the satellite-based measurements from the mean of period 1991-2020 rose slightly in December to 0.21 degrees Celsius. The mean temperature increase since satellite measurements began was 0.14 degrees Celsius per decade. The year 2021 was an average year compared to 2010 to 2020, with 0.134 degrees deviation from the thirty-year average. Six years since 2010 were warmer and 5 years were colder.
This is also true for Germany. But the German weather service gives a different impression
How the German DWD Weather Service turned cooling into warming in 2021
In its press release on Germany’s weather in 2021, the German Weather Service writes: “The mean temperature [Germany] in 2021 was 9.1 degrees Celsius (°C), 0.9 degrees above the value of the internationally valid reference period 1961 to 1990. 2021 was thus the eleventh year in a row that was too warm.”
Why does the DWD use the internationally no longer valid 1961-1990 reference period? It writes itself elsewhere: “To record the climate and its changes, mean values are formed over a period of 30 years…With the end of the year 2020, the reference period for current climatological assessments was replaced by the 1991 to 2020 period.”
Fudging with the reference period
The DWD thus followed the World Meteorological Organization (WMO)recommendation. But in the press release, the DWD still prefers to use the old, outdated period. The 1991 to 202 0reference period differs from the one of 1961 to 1990 by 1.1 degrees. So the DWD should have written : “2021 was 9.1 degrees, 1.3 degrees cooler than 2020 and even -0.2 degrees Celsius below the average from 1991 to 2020. Since 1991 there have only been 9 years colder than 2021.”
But 0.9 degrees more and the eleventh year in a row that is too warm (compared to the colder period of 1961-1990) of course fits much better with the zeitgeist.

We have updated our “Extremely Low CO2 Climate Sensitivity” scientific paper list with new papers added from 2021 and some newly discovered papers from the past.
As of 2016 this list had only 50 papers on it (as indicated by the web address). In less than 6 years the list has grown to 137 (as of today).

A few of the sample papers are shown here.

The HITRAN database of gaseous absorption spectra enables the absorption of earth radiation at its current temperature of 288K to be accurately determined for each individual atmospheric constituent and also for the combined absorption of the atmosphere as a whole. From this data it is concluded that H2O is responsible for 29.4K of the 33K warming, with CO2 contributing 3.3K and CH4 and N2O combined just 0.3K. Climate sensitivity to future increases in CO2 concentration is calculated to be 0.50K, including the positive feedback effects of H2O, while climate sensitivities to CH4 and N2O are almost undetectable at 0.06K and 0.08K respectively. This result strongly suggests that increasing levels of CO2 will not lead to significant changes in earth temperature and that increases in CH4 and N2O will have very little discernable impact.

December 1961 can be summed up in two words – cold and snow. The month was the 9th coldest on record since 1884.
The first week saw widespread snow and severe gales, whilst the Christmas week was one of the coldest of the century, with more heavy snow:
In this monthly lookback through the archives, two things are abundantly clear for every month we have checked:
1) Weather was every bit as extreme in the past
2) The weather can vary enormously from one year to another. This can not be better exemplified than the series for December, which has offered up very mild months to very cold ones, very dry ones to very wet, and very snowy ones to very little snow.

In my last post, entitled Advection, I was discussing the online MODTRAN Infrared Light In The Atmosphere model. A commenter pointed out that in the past I’d wondered about why the MODTRAN results showed that a doubling of CO2 caused a clear-sky top-of-atmosphere (TOA) decrease in upwelling longwave (LW) radiation of less than the canonical value of 3.7 watts per square meter (W/m2) per doubling of CO2. Here’s that data.

The researchers found that children do bring home what they’ve learned at school and communicate it to their parents, engaging in ways that spur parents to reconsider their views. This is partly due to the trust that exists between parents and children, making it easier to talk about an emotionally-charged issue such as climate change. Over the years, both the control and experimental groups developed more concern about climate change, but the change was most pronounced in families where children were taught the curriculum

After every tragic meteorological event there will inevitably be the alarmist cries that climate change was a substantial influence. The recent late-season tornado outbreak of Dec 10-11 is no exception. Usually most of these are appeals to emotion with no data to support the relationship between extreme weather and climate change. However, this tweet from Michael Mann pointed to a 2019 peer-reviewed study titled “Increasingly Powerful Tornadoes in the United States” by Elsner et al.1

In a recent paper, scientists expressed their surprise that the Arctic had started warming already back in the early 20th century, 100 years ago. This, along with the obligatory CO2 climate warming lip service, is described in a Cambridge University press release.
Natural oceanic currents
The Arctic Ocean has been getting warmer since the beginning of the 20th century—decades earlier than records suggest—due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
The researchers used geochemical and ecological data from ocean sediments to reconstruct the change in water column properties over the past 800 years. They precisely dated sediments using a combination of methods and looked for diagnostic signs of Atlantification, like change in temperature and salinity.
“When we looked at the whole 800-year timescale, our temperature and salinity records look pretty constant,” said co-lead author Dr. Tesi Tommaso from the Institute of Polar Sciences of the National Research Council in Bologna. “But all of a sudden at the start of the 20th century, you get this marked change in temperature and salinity—it really sticks out.”
“The reason for this rapid Atlantification of at the gate of the Arctic Ocean is intriguing,” said Muschitiello. “We compared our results with the ocean circulation at lower latitudes and found there is a strong correlation with the slowdown of dense water formation in the Labrador Sea. In a future warming scenario, the deep circulation in this subpolar region is expected to further decrease because of the thawing of the Greenland ice sheet. Our results imply that we might expect further Arctic Atlantification in the future because of climate change.”
The researchers say that their results also expose a possible flaw in climate models, because they do not reproduce this early Atlantification at the beginning of the last century.

On November 3, 2021, the renowned scientific journal Climate published a paper on solar influence on climate.
The paper by the renowned solar researcher Dr. Frank Stefani from the Helmholtz Zentrum Dresden-Rossendorf is entitled: “Solar and Anthropogenic Influences on Climate: A Regression Analysis and Tentative Predictions” and concludes that the influence of CO2 on the development of global temperatures from 1860 until today was only about half as large as the last report of the Intergovernmental Panel on Climate Change (IPCC) assumed.
As a reminder, the IPCC concludes that 98% of the warming ( 1.07 degrees out of 1.09 degrees) is human-induced. According to Stefani’s analysis, the solar influence accounts for 30-70%.
Stefani examined the course of the geomagnetic aa – index, which reflects the strength of the earth’s magnetic field. This index has been measured in Cambridge and Melbourne since 1844 and reflects the influence of solar activity. In earlier publications, Stefani had already been able to prove that the 11-year solar cycle is triggered by the gravitational forces of Venus, Earth and Jupiter, which are in orbital resonance every 11.07 years (here, here and here).
Since the Sun – influenced by all the planets (especially Jupiter and Saturn) – also moves around the center of gravity of the solar system, solar cycles arise that have become known in temperature history as the 193-year Suess-de Vries cycle and the 90-year Gleissberg cycle.

Hudson Bay has been oddly slow to freeze this year, which has led to a predictable bit of hand-wringing from certain biologists reiterating prophesies of polar bear population collapse. However, since 2009, the last time that freeze-up was anywhere near this late was 2016. In other words, far from this years’ late freeze-up being a picture of ‘the new normal,’ conditions in 2021 are actually unusual compared to the last twelve years.
Moreover, considering that 2021 fall ice formation for the Arctic in general is well ahead of 2016 (and every year since, except 2018), it’s hard to see why human-caused global warming caused by ever-increasing CO2 emissions explains the slow freeze-up of Hudson Bay. Timing of Hudson Bay freeze-up has always been highly variable from one year to the next (Castro de la Guardia et al. 2017: Fig. 3, copied below). The average freeze-up date in the 1980s was 16 November ± 5 days, while from 2005-2015 this had shifted about a week to 24 November ± 8 days (Castro de la Guardia et al. 2017:230). This year freeze-up was later than usual but last year and the three years before that the ice froze as early as it did in the 1980s. Cue the zombie apocalypse.

Until recently, human CO2 emissions were responsible for ~10% of the variance in year-to-year CO2 growth rate. But a new analysis says human CO2 emissions have been slightly declining for the last decade. So 0% responsible, apparently.
CO2 emissions derived from human activity (fossil fuel combustion and land use changes) only account for about +0.1 to 0.3 PgC/yr of the annual change in CO2 concentration. This is about “10% of the variance (σ²) of the CO2 growth rate” (Wang et al., 2013).

During an exchange with French parliamentarians this week, the EU Commission vice-president in charge of the Green Deal, Frans Timmermans, said Brussels “will support, sustain and assist those member states that make this choice” of using nuclear power. EURACTIV France reports.
Timmermans, who was speaking on Wednesday (8 December) to the National Assembly’s committees on European Affairs and Sustainable Development, promised an inclusive and ambitious ecological transition that leaves no one behind.
They discussed the work of the European Commission on various issues related to the ecological transition, ranging from the carbon market to hydrogen, the evolution of the automotive sector, nuclear power in the green taxonomy and the timetable for the Fit for 55 package.
“We know that there will be a lot of negotiating to do [by the European Commission],” said Laurence Maillard Méhaignerie, chair of the French parliament’s Committee on Sustainable Development and Regional Planning.
“It is also a work of conviction, because, in the end, it is the economic models and value chains that need to be reviewed, the lifestyles and jobs that are also profoundly transformed” by the ecological transition.
This ecological transition and the measures that come with it would not only make individuals and companies feel excluded or suffer from the transition, but, as Renew Europe MEP Pascal Canfin warned a few months ago, could also create a new movement like the Gilets jaunes.
But according to Timmermans, “no one will be left behind, abandoned in this transition”.
“We must show through concrete steps (…) that we are concerned about social issues. The transition will be social or it will not be!” he added.

THANKFULLY we usually always get to hear the inconvenient and raw truth about taxpayer funded, unelected, bloated government bureaucracies when members eventually leave and are not subject to bullying and financial repercussions. Definitely no exception here…
46 enlightening statements by IPCC experts against the IPCC:
- Dr Robert Balling: The IPCC notes that “No significant acceleration in the rate of sea level rise during the 20th century has been detected.” This did not appear in the IPCC Summary for Policymakers.
- Dr Lucka Bogataj: “Rising levels of airborne carbon dioxide don’t cause global temperatures to rise…. temperature changed first and some 700 years later a change in aerial content of carbon dioxide followed.”
- Dr John Christy: “Little known to the public is the fact that most of the scientists involved with the IPCC do not agree that global warming is occurring. Its findings have been consistently misrepresented and/or politicized with each succeeding report.”
- Dr Rosa Compagnucci: “Humans have only contributed a few tenths of a degree to warming on Earth. Solar activity is a key driver of climate.”
- Dr Richard Courtney: “The empirical evidence strongly indicates that the anthropogenic global warming hypothesis is wrong.”
- Dr Judith Curry: “I’m not going to just spout off and endorse the IPCC because I don’t have confidence in the process.”
- Dr Robert Davis: “Global temperatures have not been changing as state of the art climate models predicted they would. Not a single mention of satellite temperature observations appears in the IPCC Summary for Policymakers.”
- Dr Willem de Lange: “In 1996 the IPCC listed me as one of approximately 3000 “scientists” who agreed that there was a discernible human influence on climate. I didn’t. There is no evidence to support the hypothesis that runaway catastrophic climate change is due to human activities.”
- Dr Chris de Freitas: “Government decision-makers should have heard by now that the basis for the long-standing claim that carbon dioxide is a major driver of global climate is being questioned; along with it the hitherto assumed need for costly measures to restrict carbon dioxide emissions. If they have not heard, it is because of the din of global warming hysteria that relies on the logical fallacy of ‘argument from ignorance’ and predictions of computer models.”
- Dr Oliver Frauenfeld: “Much more progress is necessary regarding our current understanding of climate and our abilities to model it.”
- Dr Peter Dietze: “Using a flawed eddy diffusion model, the IPCC has grossly underestimated the future oceanic carbon dioxide uptake.”
- Dr John Everett: “It is time for a reality check. The oceans and coastal zones have been far warmer and colder than is projected in the present scenarios of climate change. I have reviewed the IPCC and more recent scientific literature and believe that there is not a problem with increased acidification, even up to the unlikely levels in the most-used IPCC scenarios.”
- Dr Eigil Friis-Christensen: “The IPCC refused to consider the sun’s effect on the Earth’s climate as a topic worthy of investigation. The IPCC conceived its task only as investigating potential human causes of climate change.”
- Dr Lee Gerhard: “I never fully accepted or denied the anthropogenic global warming concept until the furore started after NASA’s James Hansen’s wild claims in the late 1980s. I went to the [scientific] literature to study the basis of the claim, starting with first principles. My studies then led me to believe that the claims were false.”
- Dr Indur Goklany: “Climate change is unlikely to be the world’s most important environmental problem of the 21st century. There is no signal in the mortality data to indicate increases in the overall frequencies or severities of extreme weather events, despite large increases in the population at risk.”
- Dr Vincent Gray: “The [IPCC] climate change statement is an orchestrated litany of lies.”
- Dr Mike Hulme: “Claims such as ‘2500 of the world’s leading scientists have reached a consensus that human activities are having a significant influence on the climate’ are disingenuous … The actual number of scientists who backed that claim was only a few dozen.”
- Dr Kiminori Itoh: “There are many factors which cause climate change. Considering only greenhouse gases is nonsense and harmful.”
- Dr Yuri Izrael: “There is no proven link between human activity and global warming. I think the panic over global warming is totally unjustified. There is no serious threat to the climate.”
- Dr Steven Japar: “Temperature measurements show that the climate model-predicted mid-troposphere hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them.”
- Dr Georg Kaser: “This number [of receding glaciers reported by the IPCC] is not just a little bit wrong, it is far out by any order of magnitude … It is so wrong that it is not even worth discussing.”
- Dr Aynsley Kellow: “I’m not holding my breath for criticism to be taken on board, which underscores a fault in the whole peer review process for the IPCC: there is no chance of a chapter [of the IPCC report] ever being rejected for publication, no matter how flawed it might be.”
- Dr Madhav Khandekar: “I have carefully analysed adverse impacts of climate change as projected by the IPCC and have discounted these claims as exaggerated and lacking any supporting evidence.”
- Dr Hans Labohm: “The alarmist passages in the IPCC Summary for Policymakers have been skewed through an elaborate and sophisticated process of spin-doctoring.”
- Dr Andrew Lacis: “There is no scientific merit to be found in the Executive Summary. The presentation sounds like something put together by Greenpeace activists and their legal department.”
- Dr Chris Landsea: “I cannot in good faith continue to contribute to a process that I view as both being motivated by pre-conceived agendas and being scientifically unsound.”
- Dr Richard Lindzen: “The IPCC process is driven by politics rather than science. It uses summaries to misrepresent what scientists say and exploits public ignorance.”
- Dr Harry Lins: “Surface temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now. The case for alarm regarding climate change is grossly overstated.”
- Dr Philip Lloyd: “I am doing a detailed assessment of the IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science. I have found examples of a summary saying precisely the opposite of what the scientists said.”
- Dr Martin Manning: “Some government delegates influencing the IPCC Summary for Policymakers misrepresent or contradict the lead authors.”
- Steven McIntyre: “The many references in the popular media to a ‘consensus of thousands of scientists’ are both a great exaggeration and also misleading.”
- Dr Patrick Michaels: “The rates of warming, on multiple time scales, have now invalidated the suite of IPCC climate models. No, the science is not settled.”
- Dr Nils-Axel Morner: “If you go around the globe, you find no sea level rise anywhere.”
- Dr Johannes Oerlemans: “The IPCC has become too political. Many scientists have not been able to resist the siren call of fame, research funding and meetings in exotic places that awaits them if they are willing to compromise scientific principles and integrity in support of the man-made global-warming doctrine.”
- Dr Roger Pielke: “All of my comments were ignored without even a rebuttal. At that point, I concluded that the IPCC Reports were actually intended to be advocacy documents designed to produce particular policy actions, but not a true and honest assessment of the understanding of the climate system.”
- Dr Paul Reiter: “As far as the science being ‘settled,’ I think that is an obscenity. The fact is the science is being distorted by people who are not scientists.”
- Dr Murry Salby: “I have an involuntary gag reflex whenever someone says the science is settled. Anyone who thinks the science is settled on this topic is in fantasia.”
- Dr Tom Segalstad: “The IPCC global warming model is not supported by the scientific data.”
- Dr Fred Singer: “Isn’t it remarkable that the Policymakers Summary of the IPCC report avoids mentioning the satellite data altogether, or even the existence of satellites — probably because the data show a slight cooling over the last 18 years, in direct contradiction of the calculations from climate models?”
- Dr Hajo Smit: “There is clear cut solar-climate coupling and a very strong natural variability of climate on all historical time scales. Currently I hardly believe anymore that there is any relevant relationship between human CO2 emissions and climate change.”
- Dr Richard Tol: “The IPCC attracted more people with political rather than academic motives. In AR4, green activists held key positions in the IPCC and they succeeded in excluding or neutralising opposite voices.”
- Dr Tom Tripp: “There is so much of a natural variability in weather it makes it difficult to come to a scientifically valid conclusion that global warming is man made.”
- Dr Gerd-Rainer Weber: “Most of the extremist views about climate change have little or no scientific basis.”
- Dr David Wojick: “The public is not well served by this constant drumbeat of alarms fed by computer models manipulated by advocates.”
- Dr Miklos Zagoni: “I am positively convinced that the anthropogenic global warming theory is wrong.”
- Dr Eduardo Zorita: “Editors, reviewers and authors of alternative studies, analysis, interpretations, even based on the same data we have at our disposal, have been bullied and subtly blackmailed.”

The recent UN climate summit in Glasgow was predictably branded our “last chance” to tackle the “climate catastrophe” and “save humanity.” Like many others, US climate envoy John Kerry warned us that we have only nine years left to avert most of “catastrophic” global warming.
But almost every climate summit has been branded the last chance. Setting artificial deadlines to get attention is one of the most common environmental tactics. We have actually been told for the past half-century that time has just about run out.
This message is not only spectacularly wrong but leads to panic and poor policies.
Two years ago, Britain’s Prince Charles announced that we had just 18 months left to fix climate change. This wasn’t his first attempt at deadline-setting. Ten years earlier, he told an audience that he “had calculated that we have just 96 months left to save the world.”

It is an interesting read but not because it presents good advice to the scientific community. Rather, it presents the case that climate and ice models, which are used to make projections, are not up to the task. While those who program climate models have been trained in what we know about the basic physics involved in the biggest sea level rise issue – ice sheet dynamics – the actual projections by those models depend on parameters that are loose guesses about things we don’t know. As a result, Bassis says “…recent studies using climate and ice sheet models are, more and more often, coming to very different conclusions about future rates of sea level rise and even about the sensitivity of ice sheets to future warming…” and because of that, he tells us:
“Large discrepancies among model projections of long-term sea level rise have spawned calls among the scientific community for scientists to work on reducing uncertainty. However, focusing on uncertainty is a trap we must avoid. Instead, we should focus on the adaptation decisions we can already make on the basis of current models and communicating and building confidence in models for longer-term decisions.”

A new study throws doubt on the theory that Arctic warming is man made.
The Arctic Ocean has been warming since the onset of the 20th century, decades earlier than instrument observations would suggest, according to new research.
The study, published Wednesday in the journal Science Advances, found that the expansion of warm Atlantic Ocean water flowing into the Arctic, a phenomenon known as “Atlantification,” has caused Arctic water temperature in the region studied to increase by around 2 degrees Celsius since 1900.
Francesco Muschitiello, an author on the study and assistant professor of geography at the University of Cambridge, said the findings were worrisome because the early warming suggests there might be a flaw in the models scientists use to predict how the climate will change.

New Brunswick, N.J. (Dec. 1, 2021) – Using artificial intelligence techniques, an international team that included Rutgers-New Brunswick researchers have traced the evolution of coccolithophores, an ocean-dwelling phytoplankton group, over 2.8 million years.
Their findings, published this week in the journal Nature, reveal new evidence that evolutionary cycles in a marine phytoplankton group are related to changes in tropical seasonality, shedding light on the link between biological evolution and climate change.
Coccolithophores are abundant single-celled organisms that surround themselves with microscopic plates made of calcium carbonate, called coccoliths. Due to their photosynthetic activity, mineral production and widespread abundance throughout the world’s oceans, coccolithophores play an important role in the carbon cycle.
Scientists have long thought that climate changes’ effects on plants, animals and other organisms occur in cycles, which are reversed when each cycle is completed, thus erasing any small evolutionary changes during each cycle. In contrast, evolutionary changes, as known from the fossil record, are non-cyclic trends that occur over millions of years.

Christmas is coming. Santa’s secret summer swimming pool has frozen over. The time has come for a new monthly Arctic update.
The JAXA/ADS/ViSHOP web site is undergoing maintenance for a week, so let’s start the festive season with a look at high resolution AMSR2 area and extent:

On the Finnmark plateau, between Kautokeino and Karasjok, temperatures dropped down to -35°C on Sunday. The forecast for the coming week shows a temperature anomaly for the last days of November of 10°C below the reference period 1961-1990, the Swedish Meteorological and Hydrological Institute informs.
Coldest out is Nikkaluokta near Gällivare in Norrbotten with -36°C.
In times of climate change, the current freeze comes in sharp contrast to last fall, when meteorologists reported about the hottest October and early November ever measured, with an average of 6,7°C above normal across the Arctic.
Cold weather even sweeps the coast of northernmost Norway where the Arctic waters are kept ice-free by the warm Gulf Stream. In Kirkenes, on the border to Russia, the thermometer read -25°C on Saturday outside the Barents Observer’s office.
On the Kola Peninsula, Sunday November 28 came with temperatures from -18°C to -30°C the news online Severpost reported.
Further east in the Russian Arctic, quickly accumulating sea-ice on the Northern Sea Route has created a critical situation as a number of ships have been trapped in thick sea-ice for several weeks.
