No signs of a climate emergency for W. Hudson Bay polar bears this year ahead of UN climate meeting

by  S. Crockford’s Polar Bear Science, Oct 17, 2021 in WUWT

Reposted from Dr. Susan Crockford’s Polar Bear Science

By Susan Crockford,

Posted on October 15, 2021 | Comments Offon No signs of a climate emergency for W. Hudson Bay polar bears this year ahead of UN climate meeting

I’ve been told that another complete aerial survey of the Western Hudson Bay polar bear subpopulation (from the Nunavut to Ontario boundaries) was conducted in August this year and that the bears have been hanging out further south than usual. It will be years before the results of the population count are published, of course (especially if it’s good news) but my contacts also say virtually all of the bears are in great condition again this year.

This is significant because W. Hudson Bay bears are one of the most southern subpopulations in the Arctic (only Southern HB bears live further south) and older data from this region is being used to predict the future for the entire global population based on implausible model projections (Molnar et al. 2020). And scary predictions of future polar bear survival are often taken to be proxies for future human disasters (see ‘Polar bears live on the edge of the climate change crisis‘), a point that some activists will no doubt make in the coming weeks, as the long-awaited UN climate change bash #26 (COP26) gets underway in Glasgow, Scotland on October 31.

September Mean Temps In Northern Europe See Little Change Over Past Decades…Snow, Frost Arrive

by P. Gosselin, Oct 17, 2021 in NoTricksZone

Today we look at September mean temperatures at the stations across northern Europe for which the Japan Meteorological Agency (JMA) have enough data. We find fall is not being pushed back as we should expect in a warming world.

The JMA has published the data for September and again we see a continuing warming hiatus.

First we look at the September trends from 6 stations in Ireland since 1991:


Urban areas more likely to have precipitation-triggered landslides, exposing growing populations to slide hazards

by American Geophysical Union, Oct 12, 2021 in ScienceDaily

Urban areas may be at greater risk for precipitation-triggered landslides than rural areas, according to a new study that could help improve landslide predictions and hazard and risk assessments.

Landslides cause thousands of deaths and billions of dollars of damage annually. With over half of the world’s population in urban areas, and both urbanization and precipitation extremes expected to increase in the future, understanding how urban landscapes are affected by precipitation-triggered landslides is a pressing need.

The new study used a large database of precipitation-triggered landslides across the Pacific coast of the U.S. and isolated the influence of precipitation changes using a specific type of computer model. When the researchers controlled for other factors, like slope steepness, rock type, and wildfire, they found that urban landslide hazard was up to 10 times more sensitive to variations in precipitation than in rural areas. That means that the same increase in rainfall in rural and urban areas could be 10 times more likely to cause a landslide in a city.

The new research is published in the AGU journal Geophysical Research Letters, which publishes high-impact, short-format reports with immediate implications spanning all Earth and space sciences.

Where Have All The Disasters Gone?

by W. Essenbach, Oct 14, 2021 in WUWT

I read today that the EU is using an estimate of US$68 per tonne of CO2 emissions for the purported cost of the damages done by CO2. This is known by a Newspeak term as the “Social Cost Of Carbon”.

It made me wonder—using this estimate, what is the overall total estimated damage done by humans from emitting CO2?

The answer is $97 TRILLION dollars since 1950.

YIKES! That’s about five times the 2020 US Gross Domestic Product (the value of everything produced in the US during that year).

So I thought I’d take a look at the various largest weather-related disasters. I got the big-disaster data from Wikipedia here and arranged it by type of disaster. All values are in 2020 dollars, that is to say, they’re adjusted for inflation. Here is the result.

Aussie Met Bureau – making up 13 years of missing temperature data

by D. Mason-Jones, Oct 15, 2021 in WUWT

Upon finding a 13-year gap in its data for an important weather station in Queensland, the Australian Bureau of Meteorology homogenised data from 10 other locations to fill-in the missing years. One of these places was more than 400km away and another almost 2.5 degrees of latitude further South.

Is the resulting data credible? No, is the conclusion reached in a research Report by Australian scientist, Dr. Bill Johnston.

When the US Army Air Force (USAAF) closed its heavy bomber transit base at Charleville at the end of the Second World War the aerodrome reverted to civilian status. The base had been a link in the ferry route delivering aircraft from factories in the US to the war zone.


4 More New Reconstructions Affirm The Medieval Warm Period Was ‘Warmer Than Today’

by K. Richard, Oct 14, 2021 in NoTricksZone

From Russia to the Indian Ocean to Antarctica, surface temperatures were much warmer than  they are today during Medieval times.

1. The Eastern Russia region was 1.5°C warmer than now during the Medieval Warm Period. The modern warm-up began centuries ago and temperatures have declined in the last few centuries. Relative sea levels were 1 m higher than now 1,000 years ago.

Nazarova et al., 2021



2. Scientists use coral fossil evidence to suggest mean sea surface temperatures (SST) during the Medieval Climate Anomaly were “warmer than today”. At the two Indian Ocean study sites, there has been no obvious SST warming since 1982.

Yudawati Cahyarini et al., 2021

3. The modern (1994-2004) surface temperatures in the South China Sea are colder now than any time in the last 6000 years. Except for a brief interval ~500 years ago, SSTs have been consistently 2-4°C warmer than today since the middle Holocene.

Zhou et al., 2021


4. Modern sea ice extent for Antarctica’s Ross Sea is more extensive today (and temperatures cooler) than nearly any time in 6000 years.  It was warmer with less sea ice 1.6 to 0.7k years ago. Penguin numbers decline with cooling/increased sea ice.

Xu et al., 2021

“Climate Emergency” – Nothing But Politics And Propaganda Unsupported By Scientific Data

by  L. Hamlin, Oct 6, 2021 in WUWT

The “climate emergency” claim hyped by Scientific American and other political climate alarmist entities is based on the completely fallacious statement that “the planet is heating up way to fast” with that flawed claim representing nothing but politics and propaganda that is disproved by actually measured global temperature anomaly temperature measurements between 1988 and 2021 as well as being directly contradicted by the more than 5 year-long declining global temperature anomaly data presented by all 5 major global temperature anomaly measurement systems between 2016 and 2021.

Arctic Sea Ice Extent has been holding exceptionally well during the 2021 summer melt season.

Throughout August, higher volumes than usual have survived due to cold conditions and favorable wind patterns.

As a result, Arctic Sea Ice Extent is now the highest in 8 years, and, if this year’s trajectory continues for another week or two (which is expected), 2021 will achieve the ‘healthiest’ extent of the past 15 years (since 2006).

Only 2014, 2013, and 2009 remain in its way–though the gap is narrowing, fast:

Stalled: September Arctic Sea Remains Surprisingly Stable Over Past Decade, “Long Way From Predicted “Ice Free”

by P. Gosselin, Sept 10, 2021 in NoTricksZone

This year’s Arctic sea ice minimum reaches third highest level in a decade, latest data show.

Die kalte Sonne here presents its latest climate video. The first part looks at this year’s Arctic sea ice melt season. Now that it’s September, sea ice extent has just about reached its minimum for the year and soon the annual refreeze will begin.

We recall that years ago alarmist scientists and wacko activists, like al Gore, predicted an ice free Arctic by now. Today we look at the most recent data and we see that we are a very long way from that point.

Very slow August melt this year

What follows is the chart from the National Snow and Ice Data Center (NSIDC):

Countdown to COP26 on the road to failure

by D. Wojick, Sept 7, 2021 in Fact 

It is less than 60 days until COP26 convenes in Glasgow. We can expect a flood of climate horror stories (including flooding). But there will also be some discussion of the actual issues, so here is a brief breakdown of the big four.

Keep in mind that the alarmists have a bit of a civil war going on, between what I call the moderates and the radicals. The moderates have been at it for over 30 years and the radicals are fed up. The moderates now have a net zero target of 2050, while the radicals want 2030, so the difference is pretty stark. The last two COPs were partly paralyzed by this split, especially COP25. This fight will be a major factor in Glasgow.

The first two big issues are old business, money business to be precise. Of course it is all about money but these two are that by name — trading and finance.


The first big money issue is finalizing and launching the emissions trading scheme. This is part of the so-called Paris rule book, which was supposed to be settled well before now. The developed countries are depending on buying emission indulgences, which the developing countries dearly want to sell to them. This is the “net” in net zero.

Also some countries have indulgences left over from the now ended Kyoto trading. They want to bring these forward to be included in the new scheme. Some moderates oppose this.

The real problem is the radicals despise emission trading. They want every country to eliminate its own emissions, at home. Thus their target is actually more like gross zero, although some might allow domestic offsets. That issue has yet to really arise, but the trading fight froze COP25.


Lithium: How the Taliban will fight climate change?

by D.Middleton, Aug 24, 21, 2021 in WUWT

Afghanistan is the “the Saudi Arabia of lithium” –a metal that is essential for electric vehicle batteries and battery storage technologies. According to the International Energy Agency these technologies account for 30 percent of the current global demand for lithium. Demand for lithium is projected to increase 40-fold above 2020 levels by 2040, along with rare earth elements, copper, cobalt, and other minerals in which Afghanistan is also naturally rich.

China currently controls the supply chains for most of the production and/or processing of these minerals. Now China may have another source.

Just two years ago, many mainstream media outlets declared that sea ice at the South Pole was melting at an “astonishing” rate.

As recently pointed out by, German national daily Süddeutsche Zeitung reported in June 2019 that Antarctic sea ice had “shrunk 1.8 million square kilometers”, writing: “the massive disappearance of ice is astonishing”.

And while the reporting was technically factual, it has proven to be yet more AGW-driving obfuscation and cherry-picking rather than well-founded indications of a concerning climatic trend.

And now, in 2021, as the ice sharply rebounds, these same MSM outlets have fallen silent–which is speaking volumes…


Sea ice at the South Pole has rebounded in 2020 and 2021, to the levels of some 3-decades ago.

Moreover, the trend of the past 40+ years (the satellite era) remains one of significant growth (of approx 1% per decade).

In 2021, Antarctic sea ice is actually tracking well-above the multidecadal average (shown below).


The climate-ambulance chasing MSM have stopped reporting on the state of the ice across the Southern Hemisphere.


“Researchers are in agreement that the decline in Antarctic sea ice from 2016 to 2019 is due to natural causes,” writes Die kalte Sonne. “Obviously this is not a good topic for the Süddeutsche Zeitung, who prefer not to report on the ice recovery.”

Not informing the public about the most recent developments, but instead leaving them with a false impression based on carefully cherry-picked data from two years prior, is a classic disinformation technique that has long been perfected by the activist media.

New Study: 2000-Year Precipitation Reconstructions Expose Climate Models Still Of Junk Grade

by Atwood et al., Aug 18, 2021 in NoTricksZone

A new study by Atwood et al (2021) published in the journal of Paleoceanography and Paleoclimatology found there’s “poor agreement” between precipitation reconstructions and model simulations over the past 2000 years. This means future projections made by current models are unreliable. 


Models and reconstructions don’t agree

These comprehensive reconstructions show that from 800 to 1000 CE there was a pronounced drying event relative from the eastern Pacific and parts of Mesoamerica.

Also the period “1400–1700 CE is marked by pronounced hydroclimate changes across the tropics, including dry and/or isotopically enriched conditions in South and East Asia, wet and/or isotopically depleted conditions in the central Andes and southern Amazon in South America, and fresher and/or isotopically depleted conditions in the Maritime Continent.”

The study’s abstract also notes how there’s a glaring disagreement between the simulations done by models and what the reconstructions show: “We find notable dissimilarities between the regional hydroclimate changes and global-scale and hemispheric-scale temperature reconstructions, indicating that more work needs to be done to understand the mechanisms of the widespread tropical hydroclimate changes during the LIA.”

Antarctic Sea Ice Recovery Surprises Scientists… Classic Disinformation Technique Of Not Reporting

by P. Gosselin, Aug 15, 2021 in NoTricksZone

Just two years ago, many of Germany’s mainstream media outlets declared sea ice at the South Pole was melting at an “astonishing” rate. For example, the left of center, Munich based Süddeutsche Zeitung,

German national daily Süddeutsche Zeitung (above) reported in June, 2019, that Antarctic sea ice had “shrunk 1.8 million square kilometers”, writing: “the massive disappearance of ice is astonishing”.

But many readers here, who are aware of the real data, know nothing of the sort over the long term has happened since satellite measurements began over 40 years ago.

Massive sea ice rebound goes unreported

Today, two years later, German climate science site Die kalte Sonne looks at recent sea ice developments in Antarctica – noting that the climate-ambulance chasing mainstream media like the Süddeutsche Zeitung have since mysteriously stopped reporting on Antarctica. Here’s why:

La cerise catastrophiste du GIEC

by ScienceClimatEnergie, 13 août 2021

Il fallait faire fort et ils l’ont fait : la toute première figure du résumé pour décideurs (SPM) du dernier rapport du GIEC (l’AR6), reproduite ci-dessous (Figure 1), est une véritable cerise sur leur gâteau catastrophiste. La courbe est destinée à faire peur au public, par exemple aux étudiants qui ne connaissent rien (ou très peu) de la science climatique (démonstration ici) et qui ont déjà décidé de faire grève en début d’année scolaire. Elle est également destinée aux décideurs trop occupés à leurs affaires politiques pour pouvoir se permettre d’analyser la courbe en profondeur. N’oubliez pas que le Royaume-Uni accueillera la 26eConférence des Parties des Nations unies sur le changement climatique (COP26) à Glasgow du 1er au 12 novembre 2021. Le SPM tombe donc à pic pour influencer les décideurs qui devront voter.



En comparant des pommes et des poires (raison n°1), en effaçant des chapitres entiers des livres d’histoire (raison n°2) et en jouant sur l’échelle du graphique (raison n°3), la Figure SPM.1 du GIEC remplit parfaitement son rôle : faire peur aux gens qui ne prennent pas le temps de réfléchir. Et cela marche, les manifestations ne font que commencer. Bravo le GIEC!

Mais ce super tour de passe-passe, ne suggère-t-il pas que le GIEC a perdu les pédales, est à bout de souffle et ne sait plus quoi inventer pour sortir de l’impasse? S’agirait-il d’une première forme de ‘suicide scientifique’? Espérons quand même que de nombreux scientifiques ne seront pas dupes, sinon il y a vraiment de quoi désespérer.

The UN IPCC buries two millennia of fluctuating temperatures

by P. Homewood, Aug 16, 2021 in NotaLotofPeopleKnowThat


That there has been 1.1°C of warming since 1850 is not especially controversial.  There is some disagreement about the degree to which it reflects the “recovery” from the mini-Ice Age (when there were Ice Fairs on the Thames among other events not seen today) and the effects of increased CO2 emissions.

The controversial part is the removal of temperature oscillations commonly thought to have occurred over the course of the past 2,000 years. These include warming that was known to have occurred in Roman times and again in the tenth century when the Vikings colonised Greenland until 1250, and the cold period 1400-1700.  Such events are downgraded as being either exaggerated or localised.

The earlier iteration of the IPCC 2021 picture was the notorious hockey stick fabrication by Michael Mann.  Mann cherry-picked data from tree rings and spliced together incongruent data sources, and reported his “findings” in a 1998 paper. Like the latest IPCC report, this showed a flat temperature trend until the 20th Century, then a sharp rise.

The IPCC in its 2001 report used Mann’s graph as its poster child to substantiate human-induced global warming.  In the years after 2001 the IPCC quietly dropped Mann’s “hockey stick”.  Its discreditating was completed by 2009 release of confidential emails (dubbed “Climategate”), which showed Michael Mann as the conductor of other climate scientists seeing a need to eradicate the “medieval warming period” in order to make the case that the modern warming is unique.

The chicanery under which this strategy was conducted resulted in legal cases.  Canadian scientist Tim Ball called Mann a fraud, Mann sued and the subsequent court case lasted a decade before finding against Mann. (Mann has managed to string out another case that he brought against Mark Steyn for even longer).

But in the 2021 climate review the “hockey stick” is again the main feature.

Here We Go Again: UN Climate Panel Continues Decades-Long Climate Fear Porn Tradition

by J. Vazquez, Aug 9, 2021 in mrcNewsBusters

Run for cover! The Intergovernmental Panel on Climate Change (IPCC) is warning that we only have a few years to save the planet — a nugget of fear porn the United Nations and the media have been peddling for decades.

Liberal outlet The Guardian ran a climate propaganda story headlined “Major climate changes inevitable and irreversible – IPCC’s starkest warning yet.” The outlet took a nosedive into absurdity by blaming humanity for “climate crimes”: “IPCC’s verdict on climate crimes of humanity: guilty as hell.” The outlet took the IPCC report and screeched that unless “rapid and drastic reductions in greenhouse gases in this decade” are initiated, temperatures would rise by “more than” 1.5 degrees Celsius “above pre-industrial levels,” bringing a “climate breakdown” of “widespread devastation and extreme weather.” President of the 2021 U.N. Climate Change Conference Alok Sharma fearmongered that failing to limit warming to 1.5 degrees Celsius would be “‘catastrophic.'” [Emphasis added.]

The IPCC’s latest scare tactics reflect the words of University of Southampton Professor emeritus John Brignell, as reported by Climate Depot: “The creation of the UN IPCC was a cataclysmic event in the history of science. Here was a purely political body posing as a scientific institution.”

Hoover Institution visiting fellow Bjorn Lomborg has pointed out on Twitter, “UN routinely warns us that we have just a few years left until catastrophe.” The U.N. has a sorry record of those predictions failing to materialize.

The IPCC Summary For Policymakers

by P. Homewood, Aug 10, 2021 in NotaLotofPeopleKnowThat

If we ignore all of the alarmist rhetoric in the IPCC’s Summary for Policymakers, the real nitty gritty lies in these four sections:



The reality is that our weather is no worse now than it was 150 years ago. Indeed I would strongly suggest that governments all around the world would be terrified if they were told we were going back to the climate Little Ice Age.

Think I’m kidding? This was exactly scientists thought was going to happen during the global cooldown in the 1970s, and governments were genuinely alarmed.

All that is left in the IPCC report is a host of highly subjective projections of what might happen in the future.

Inside The Acceleration Factory

by W. Eschenbach, Aug 11, 2021 in WUWT

Nerem and Fasullo have a new paper called OBSERVATIONS OF THE RATE AND ACCELERATION OF GLOBAL MEAN SEA LEVEL CHANGE, available here. In it, we find the following statement:

Both tide gauge sea level reconstructions and satellite altimetry show that the current rate of global mean sea level change is about 3 mm yr–1, and both show that this rate is accelerating.

So the claim is that tide gauges show acceleration. Let’s start with a look at the Church and White (hereinafter C&W) estimate of sea level from tide gauges around the world, which is the one used in the Nerem and Fasullo paper. The C&W paper is here.

How Climate Scenarios Lost Touch With Reality

by R. Pielke Jr & J. Ritchie, Aug, 4, 2021 in CO2Coalition

A failure of self-correction in science has compromised climate science’s ability to provide plausible views of our collective future.

The integrity of science depends on its capacity to provide an ever more reliable picture of how the world works. Over the past decade or so, serious threats to this integrity have come to light. The expectation that science is inherently self-correcting, and that it moves cumulatively and progressively away from false beliefs and toward truth, has been challenged in numerous fields—including cancer research, neuroscience, hydrology, cosmology, and economics—as observers discover that many published findings are of poor quality, subject to systemic biases, or irreproducible.

In a particularly troubling example from the biomedical sciences, a 2015 literature review found that almost 900 peer-reviewed publications reporting studies of a supposed breast cancer cell line were in fact based on a misidentified skin cancer line. Worse still, nearly 250 of these studies were published even after the mistaken cell line was conclusively identified in 2007. Our cursory search of Google Scholar indicates that researchers are still using the skin cancer cell line in breast cancer studies published in 2021. All of these erroneous studies remain in the literature and will continue to be a source of misinformation for scientists working on breast cancer.

In 2021, climate research finds itself in a situation similar to breast cancer research in 2007. Our research (and that of several colleagues) indicates that the scenarios of greenhouse gas (GHG) emissions through the end of the twenty-first century are grounded in outdated portrayals of the recent past. Because climate models depend on these scenarios to project the future behavior of the climate, the outdated scenarios provide a misleading basis both for developing a scientific evidence base and for informing climate policy discussions. The continuing misuse of scenarios in climate research has become pervasive and consequential—so much so that we view it as one of the most significant failures of scientific integrity in the twenty-first century thus far. We need a course correction.

In calling for this change, we emphasize explicitly and unequivocally that human-caused climate change is real, that it poses significant risks to society and the environment, and that various policy responses in the form of mitigation and adaptation are necessary and make good sense. However, the reality and importance of climate change does not provide a rationale or excuse for avoiding questions of research integrity any more than does the reality and importance of breast cancer. To the contrary, urgency makes attention to integrity that much more important.

Scenarios and baselines

Pielke Jr. on AR6

by Pielke Jr. , Aug 9, 2021 in WUWT

Some initial comments
Think of these as working notes
Comments welcomed
Let’s go . . .

Let’s start with scenarios

This is rather huge
“In general, no likelihood is attached to the scenarios assessed in this Report”

So that means that users of the scenarios have to independently assess likelihoods

That said: “the likelihood of high emission scenarios such as RCP8.5 or SSP5-8.5 is considered low”

In The 1970s Climate Modification Proposals Included Purposely Melting Arctic Sea Ice With Black Soot

by K. Richard, Aug 2, 2021 in NoTricksZone

In his 1975 book The Genesis Strategy, the late climate scientist Dr. Stephen Schneider reviewed contemporary climate modification proposals to reduce the severe 1960s and 1970s droughts, floods, and extreme weather…which were at that time associated with the ongoing global cooling. One proposal was to eliminate the Arctic’s sea ice by having aircraft dump black soot on the ice pack.

In 1974, Schneider reported that the Earth had warmed 0.6°C from 1880 to 1940, then cooled -0.3°C from 1940 to 1970. He suggested the warming could not have been due to human activity, but possibly the ongoing cooling might have been.

The New Pause lengthens again

by C. Monckton of Brenchley, Aug 3 2021 in WUWT

The New Pause has lengthened by another two months. Even though the brief la Niña that began in late 2020 has now ended, on the UAH dataset there has been no global warming for 6 years 6 months till July 2021. As always, the Pause is calculated as the longest period ending in the present that shows no warming trend, taken as the least-squares linear-regression trend on the UAH satellite monthly global mean surface temperature anomalies for the lower troposphere:


Criminal Negligence? Authorities Failed To Heed Flood Warnings…”Let People Drown”…”Monumental System Failure”

by P. Gosselin, July 17, 2021 in WUWT/NTZ

Harsh criticism of German authorities failing to act is mounting in the aftermath of the recent deadly floods.

Germany’s New Orleans

Many of the over one hundred people died in the recent flood disaster in Central Western Germany could have been prevented – had the responsible institutions heeded the warnings that had been already issued days in advance by the weather services. Authorities had been warned days early, yet they did nothing to prepare to evacuate and mobilize resources. The media did nothing to warn.

Veteran meteorologist: “much could have been prevented”

Swiss meteorologist Jörg Kachelmann told in a PULS 24 interview that “much of it could have been prevented” and that “people could have been warned”.

“The rainfall could not have been prevented” but the authorities and the “media could have warned the population.” The veteran Swiss meteorologist is surprised by the “surprise of the authorities” and says “people could have been evacuated or at least items moved to higher floors”.

Let people drown” as “they broadcast shit”

Kachelman also commented to Germany’s leading national dailyBild: “It hurts when the very people who would have the resources to accompany such a weather situation 24/7 do nothing to save lives. But they broadcast shit and let people drown.”
