Recently : field works (3 to 5 weeks) Congo- Brazzaville 2012, 2015, 2016 (carbonate Neoproterozoic). Degree in geological sciences at the Free University of Brussels (ULB) in 1974, I went to Algeria for two years teaching mining geology at the University of Constantine. Back in Belgium I worked for two years as an expert for the EEC (European Commission), first on the prospecting of Pb and Zn in carbonate environments, then the uranium exploration in Belgium. Then Assistant at ULB, Department of Geology I got the degree of Doctor of Sciences (Geology) in 1985. My thesis, devoted to the study of the Devonian carbonate sedimentology of northern France and southern Belgium, comprised a significant portion of field work whose interpretation and synthesis conducted to the establishment of model of carbonate platforms and ramps with reefal constructions. I then worked for Petrofina SA and shared a little more than two years in Angola as Director of the Research Laboratory of this oil company. The lab included 22 people (micropaleontology, sedimentology, petrophysics). My main activity was to interpret facies reservoirs from drillings in the Cretaceous, sometimes in the Tertiary. I carried out many studies for oil companies operating in this country. I returned to the ULB in 1988 as First Assistant and was appointed Professor in 1990. I carried out various missions for mining companies in Belgium and oil companies abroad and continued research, particularly through projects of the Scientific Research National Funds (FNRS). My research still concerns sedimentology, geochemistry and diagenesis of carbonate rocks which leads me to travel many countries in Europe or outside Europe, North Africa, Papua New Guinea and the USA, to conduct field missions. Since the late 90's, I expanded my field of research in addressing the problem of mass extinctions of organisms from the Upper Devonian series across Euramerica (from North America to Poland) and I also specialized in microbiological and geochemical analyses of ancient carbonate series developing a sustained collaboration with biologists of my university. We are at the origin of a paleoecological model based on the presence of iron-bacterial microfossils, which led me to travel many countries in Europe and North Africa. This model accounts for the red pigmentation of many marble and ornamental stones used in the world. This research also has implications on the emergence of Life from the earliest stages of formation of Earth, as well as in the field of exobiology or extraterrestrial life ... More recently I invested in the study from the Precambrian series of Gabon and Congo. These works with colleagues from BRGM (Orléans) are as much about the academic side (consequences of the appearance of oxygen in the Paleoproterozoic and study of Neoproterozoic glaciations) that the potential applications in reservoir rocks and source rocks of oil (in collaboration with oil companies). Finally I recently established a close collaboration with the Royal Institute of Natural Sciences of Belgium to study the susceptibility magnetic signal from various European Paleozoic series. All these works allowed me to gain a thorough understanding of carbonate rocks (petrology, micropaleontology, geobiology, geochemistry, sequence stratigraphy, diagenesis) as well in Precambrian (2.2 Ga and 0.6 Ga), Paleozoic (from Silurian to Carboniferous) and Mesozoic (Jurassic and Cretaceous) rocks. Recently (2010) I have established a collaboration with Iraqi Kurdistan as part of a government program to boost scientific research in this country. My research led me to publish about 180 papers in international and national journals and presented more than 170 conference papers. I am a holder of eight courses at the ULB (5 mandatory and 3 optional), excursions and field stages, I taught at the third cycle in several French universities and led or co-managed a score of 20 Doctoral (PhD) and Post-doctoral theses and has been the promotor of more than 50 Masters theses.

Greenland Sees Significant Snow, Ice Mass Loss Slowdown Over Past Decade, Danish Data Show

by P. Gosselin, Nov 14, 2021 in NoTricksZone


Data from the Danish Polar Portal shows Greenland ice melt slowing significantly over past 10 years. Increasingly rapid mass loss is a myth. 

German climate site Die kalte Sonne here looks at whether Greenland is really melting faster or not in its 78th climate and energy video (3rd segment).

Satellite measurement has allowed accurate measurements over the years and so reliable trends are detectable.

Greenland has added mass since July

Over the past year, since September 2020, Greenland has seen a number of heavy snowfalls, as depicted by the solid blue line in the chart by the Danish polarportal.dk:

BBC’s Fake GHGs Graph

by P. Homewood, Nov 15, 2021 in NotaLot ofPeopleKnowThat


For the last few weeks, the BBC has been regularly publishing the above graph from Climate Action Tracker, showing the extra emission reductions resulting from the new NDCs, National Plans, submitted for COP26.

Essentially they estimate a figure of 3.3 to 4.7 GtCO2e for all GHGs. Significantly this means that they will still be much higher than 2010 in 2030. According to the science, they need to be cut by 45% from 2010 levels to stay on track for 1.5C

Curiously however in the last few days, the BBC has dropped the above graph, and replaced with an ostensibly fake one, which claims that the new COP26 pledges will cut emissions by 10.5 GtCO2e, more than double the Climate Tracker numbers, bringing 2030 levels down to 90% of 2010 ones.

COP 26: Planet saved, now what?

by D. Wojick, Nov 11, 2021 in CFact


A hugely funny thing happened on the outskirts of COP 26. The press seems to have missed this huge news, but the Paris Accord’s goal of keeping global warming below 2 degrees has now been met. Well okay, it has just been promised by politicians. But if you take political promises seriously, as they do in COP-world, the end is here.

Specifically, several independent green analyses find that the various commitments made at COP 26 would limit global warming to just 1.8 or so degrees. The Paris target is “less than 2 degrees” so there you have it. Target met!

Where are the green headlines screaming “Planet saved”? Where are the green marches of celebration instead of protest?

The funny part is that this paper success raises big problems for the climate activist movement. All that remains is to makes sure the promises are kept. But these promises are for dates that range from from 2030 to way out in 2060 or 2070. There is almost nothing to do now as far as implementation is concerned. What are all these activists to do?

There are some technical things that need doing, at some point. In particular these big promises are not part of the actual COP. The COP is the Conference of the Parties to the UN Framework Convention on Climate Change, which includes over 200 countries, each of which has a veto.

None of these grand promises, even those made by over 100 countries like the methane reduction goal for 2030, are part of the official COP. In fact the thousands of national COP negotiators are reportedly “sour” because the grand announcements got all the press.

The actions of the COP are highly formal. What has to happen now is that all of these promises get incorporated into the official Nationally Determined Contribution (NDC) for each country that is a member of the Paris Accord. Even here the next round of updated NDCs is not due until 2025. So in a very real sense there is nothing urgent to do now, even though the Planet is saved (on paper).

Some of the global activists might simply reject the finding that the Paris target has been reached. This may be tough because one of these Earth saving analyses was done by the prestigious (to alarmists) International Energy Agency. IEA got a low 1.8 degrees of warming if all the agreements and public promises are met by every country.

Die hard alarmists might argue that the target is 1.5 degrees, not 1.8. But China has said officially that 1.5 is not the Paris Accord target and if people want it the entire Accord will have to be renegotiated.

There are some relatively immediate issues on the COP table that relate to these promises. One is finally establishing the global emissions trading system. Many of the “rich” country NDCs depend on trading in order to get to so-called net zero emissions. They need to buy indulgences for their air transport and shipping, which cannot be electrified.

Then there is the huge unresolved issue called finance. Many of the developing country NDCs are contingent on the rich countries paying the huge cost of getting to net zero, or even for hitting lesser targets like the 30% methane cut by 2030. The supposedly agreed on funding of $100 billion a year from 2020 through 2024 has yet to appear. Developing countries, led by an alliance of African leaders, is calling for a trillion a year beginning 2025, but that target too is a long way off.

Where does the climate alarmist movement go from here? Greta Thunberg in her new newly profane persona has asked of COP 26 “What the F are they doing in there.” The COPers can now answer “Saving the planet, what are you doing out there.”

Of course it is all just political promises. Many are economically impossible, some physically so. At this point that is not the point. The alarmist movement has the serious problem of apparent success. How they handle it will be fun to watch.

Glasgow Is Fake…Number Of Typhoons Formed In Pacific Has Trended Downward Significantly Since 1951!

by P. Gosselin, Nov 12, 2021 in NoTricksZone


The Glasgow climate conference has been a three-ring circus of doomsday clowns, all warning of ever increasing extreme weather events. But as hurricane trends have shown, most of it is baseless hysteria.

Pacific typhoons trending downward

As the 2021 tropical cyclone season for the northern hemisphere approaches its end, the Japan Meteorological Agency (JMA) presents the latest data for Pacific typhoons — going back to 1951.

Autocorrelation in CO2 and Temperature Time Series

by A. May, Nov 14, 2021 in WUWT


In my last post I plotted the NASA CO2 and the HadCRUT5 records from 1850 to 2020 and compared them. This was in response to a plot posted on twitter by Robert Rohde implying they correlated well. The two records appear to correlate because the resulting R2 is 0.87. The least square’s function used made the global temperature anomaly a function of the logarithm to the base 2 of the CO2 concentration (or ‘log2CO2‘). This means the temperature change was assumed to be linear with the doubling of the CO2concentration, a common assumption. The least squares (or ‘LS’) methodology assumes there is no error in the measurements of the CO2 concentration and all error resulting from the correlation (the residuals) resides in the HadCRUT5 global average surface temperature estimates.

In the comments to the previous post, it became clear that some readers understood the computed R2(often called the coefficient of determination), from LS, was artificially inflated because both X (log2CO2) and Y (HadCRUT5) were autocorrelated and increased with time. But a few did not understand this vital point. As most investors, engineers, and geoscientists know, two time series that are both autocorrelated and increase with time will almost always have an inflated R2. This is one type of “spurious correlation.” In other words, the high R2 does not necessarily mean the variables are related to one another. Autocorrelation is a big deal in time series analysis and in climate science, but too frequently ignored. To judge any correlation between CO2 and HadCRUT5 we must look for autocorrelation effects. The most tool used is the Durbin-Watson statistic.

The Durbin-Watson statistic tests the null hypothesis that the residuals from a LS regression are not autocorrelated against the alternative that they are. The statistic is a number between 0 and 4, a value of 2 indicates non-autocorrelation and a value < 2 suggests positive autocorrelation and a value >2 suggests negative autocorrelation. Since the computation of R2 assumes that each observation is independent of the others, we hope that we get a value of 2, that way the R2 is valid. If the regression residuals are autocorrelated and not random—that is normally distributed about the mean—the R2 is invalid and too high. In the statistical program R, this is done—using a linear fit—with only one statement, as shown below:

17 More Studies Show No Unusual Warming Trend In Recent Centuries…And A Warmer Holocene

by K. Richard, Nov 11, 2021 in NoTricksZone


Cruz et al., 2021 (Argentina)

Argentina’s (Tixi Cave) present annual temperature is 13.8°C. It was 3.5°C (17.3°C), 1.7°C (15.5°C), 3°C (16.8°C), and 4.5°C (18.3°C) warmer than today 3496, 1656, 656, and 160 years before present, respectively. So ~1860 was 4.5°C warmer.

 

 

 

China and India among 22 nations calling for key section to be cut from COP26 agreement

by Angela Dewan, Ivana Kottasová and Amy Cassidy, CNN, Updated 1915 GMT (0315 HKT) November 11, 2021


Glasgow, Scotland (CNN)After 11 days of climate talks that have included progress on protecting forests, phasing out coal and transitioning to electric cars, the future of our planet has boiled down to one key thing: who’s going to pay for the mess we’re in?

On Thursday afternoon, the eve of the final day of COP26, huge gaps remain between what different countries want on key issues, including how ambitious the world should be in slashing greenhouse gas emissions, all part of what climate folks call “mitigation.”
In what has been the fiercest opposition to the summit’s draft agreement published Wednesday, Bolivia’s chief negotiator Diego Pacheco said his country and 21 other allied nations — including major emitters like China, India and Saudi Arabia — would oppose the entire section on climate change mitigation.

Temperature Bottom Falling Out: Antarctica’s Coldest Half-Year Since Measurements Began 60 Years Ago

by P. Gosselin, Nov 9, 2021 in NoTricksZone


Antarctica sets a record cold six month period…Neumayer station sets new winter record low, sees rapid cooling since 2000!

German Die kalte Sonne here features Antarctica’s record cold winter – the coldest since temperature measurements began some 60 years ago.

Coldest April-September period

The Amundsen Scott station at the South Pole recorded a mean temperature of -60.9°C for the April 1 to September 30 period, according to the US National Snow and Ice Data Center (NSIDC). For the June-July-August period, the mean was minus 62.9°C  — the second coldest recorded.

Apparently the 140 or so ppm added CO2 couldn’t trap enough heat to prevent a record cold from being set. The previous record for June-July-August was set in 2004.

Neumayer sets record cold, sees 3°C of cooling since 1985

Die kalte Sonne reports that a record was also set at the German Neumayer Antarctic station, located on the Antarctic coast, which saw a mean June-July-August temperature of -28.6°C.

A Potted History of Glaciers

by P. Homewood, Nov 10, 2021 in NotaLotofPeopleKnowThat


A friend recently suggested that “melting glaciers” must surely prove “global warming is true”.

It is a common belief. After all, glaciers are a visible phenomenon and it all sounds logical.

As you know, I have written extensively about glaciers, (see the “glaciers” tab on the sidebar). But it is worth posting this potted history of them:

Summary

The modern day retreat of glaciers is part of a much longer natural cycle. Indeed, we find evidence of that cycle going back long before the Middle Ages.

Lamb, for instance, claims that glaciers in the Alps and Norway were advancing between 800 and 400BC, reaching an extent almost as great as during the Little Ice Age. They advanced again around AD600 to a similar position as before.

In between times, of course, the same glaciers also retreated, both during the Roman Warm Period and the Medieval Warming Period.

Whether man-made warming has played any part in modern glacial retreat, we know that:

  • Most of the retreat since the 18thC occurred before any possible impact from humans.
  • Glaciers were smaller than now in the Middle Ages
  • There is nothing unprecedented or alarming about the current state of the world’s glaciers

All of this is common knowledge amongst glaciologists. But for some reason the world of climate science does not want the public to know.

The Role Of Critical Minerals In The Clean Energy Transition

by P. Homewood, Nov 10, 2021 in NotaLotofPeopleKnowThat


Minerals are essential components in many of today’s rapidly growing clean energy technologies – from wind turbines and electricity networks to electric vehicles. Demand for these minerals will grow quickly as clean energy transitions gather pace. This new World Energy Outlook Special Report provides the most comprehensive analysis to date of the complex links between these minerals and the prospects for a secure, rapid transformation of the energy sector.
Alongside a wealth of detail on mineral demand prospects under different technology and policy assumptions, it examines whether today’s mineral investments can meet the needs of a swiftly changing energy sector. It considers the task ahead to promote responsible and sustainable development of mineral resources, and offers vital insights for policy makers, including six key IEA recommendations for a new, comprehensive approach to mineral security.

COP26–The Stage Show

by P. Homewood, Nov 9, 2021 in NotaLotofPeopleKnowThat


Maybe it’s just me, but I get the impression that COP26 is little more than a stage managed exercise in virtue signalling, allowing world leaders and the great and the good to pat themselves on the back and pretend they are saving the planet.

Today’s discussions will mainly focus, believe it or not, on gender issues! Yesterday’s big event was a speech by yesterday’s man, Obama, calling on “young people to remain angry”.

If you think back to Paris and earlier COPs, they were acted out as some sort of drama. Arguments between countries, late night sessions, all miraculously resolved at the 11th hour with an “Agreement” to save the planet.

Maybe the scene for COP26 was set months ago, when it became clear that China, India and the rest of the developing world would not commit to any emission reductions by 2030, or for that matter 2035.

And if any doubts about this lingered, the refusal of Xi Jinping and Vladimir Putin to turn up soon cleared those up.

To recap, the main purpose of COP26 was to get countries to set new emission targets, as mandated every five years under the Paris Agreement. Given that the pledges made at Paris, the NDCs, or Nationally Determined Contributions, only set targets for 2030, the logic was that this year would see pledges for 2035.

But this has not been the case. Instead some countries have made small adjustments to their 2030 targets, which in overall terms won’t make the blindest of difference:

China’s Climate Goals Hinge on a $440 Billion Nuclear Buildout

by D. Murtaugh & K. Chia, Nov 2, 2021 in BloombergGreen


China is planning at least 150 new reactors in the next 15 years, more than the rest of the world has built in the past 35.

Nuclear power once seemed like the world’s best hope for a carbon-neutral future. After decades of cost-overruns, public protests and disasters elsewhere, China has emerged as the world’s last great believer, with plans to generate an eye-popping amount of nuclear energy, quickly and at relatively low cost.

China has over the course of the year revealed the extensive scope of its plans for nuclear, an ambition with new resonance given the global energy crisis and the calls for action coming out of the COP26 Climate Summit in Glasgow. The world’s biggest emitter, China’s planning at least 150 new reactors in the next 15 years, more than the rest of the world has built in the past 35. The effort could cost as much as $440 billion; as early as the middle of this decade, the country will surpass the U.S. as the world’s largest generator of nuclear power.

Presidents Xi and Putin (and the Hedge Funds!) are laughing at us

by P. Homewood, Nov 8, 2021 in NotaLotofPeople KnowThat


The gap between rhetoric and fact is a perennial feature of politics. But seldom can the chasm between claim and reality have been as wide as that displayed by Alok Sharma at the Cop26 conference in Glasgow. The British president of the latest intergovernmental climate change gathering told the delegates (and the world’s media) that “the end of coal is in sight”, as a result of the agreement he had negotiated.


That was the rhetoric. Now the fact. Not only was the declaration to phase out coal by the 2040s not signed by the world’s top three consumers (China, India and America, which account for more than 70 per cent of the global CO2 emissions from burning the stuff); the pledge itself was neutered by the addition of the get-out “or as soon as possible thereafter”.

CO2 and Temperature

by A. May, Nov 9, 2021 in WUWT


I had a very interesting online discussion about CO2 and temperature with Tinus Pulles, a retired Dutch environmental scientist. To read the whole discussion, go to the comments at the end of this post. He presented me with a graphic from Dr. Robert Rohde from twitter that you can find here. It is also plotted below, as Figure 1.

Conclusion

I’m not impressed with Rohde’s display. The coefficient of correlation is decent, but it does not show that warming is controlled by changes in CO2, the temperature reversals are not explained. The reversals strongly suggest that natural forces are playing a significant role in the warming and can reverse the influence of CO2. The plots show that, at most, CO2 explains about 50% of the warming, something else, like solar changes, must be causing the reversals. If they can reverse the CO2-based warming and overwhelm the influence of CO2 they are just as strong.

Climate change is no catastrophe

by M. Shellenberger, Nov 3, 2021 in Unherd


No global problem has ever been more exaggerated than climate change. As it has gone from being an obscure scientific question to a theme in popular culture, we’ve lost all sense of perspective.

Here are the facts: in Europe, emissions in 2020 were 26% below 1990 levels. In the United States, emissions in 2020 were 22% below 2005 levels. Emissions are likely to start declining, too, in developing nations, including China and India, within the next decade. Most nations’ emissions will be bigger this year than last, due to post-Covid economic growth. But global emissions are still likely to peak within the next decade.

And the result will be a much smaller increase in global average temperatures than almost anyone predicted just five years ago. The best science now predicts that temperatures are likely to rise just 2.5-3°Cabove pre-industrial levels. It’s not ideal, but it’s a far cry from the hysterical and apocalyptic predictions of 6°C, made just a decade ago. A 3°C increase is hardly an existential threat to humanity.

Not that you’d know it, if you had half an eye on the headlines this summer. The floods, fires and heatwaves that plagued the world were, for many observers, proof that the impacts of climate change have already become catastrophic. In Europe, more than 150 people died in flooding. In the United States, wildfire season started earlier and lasted longer, razing hundreds of thousands of acres. Around the world, hundreds died from heatwaves.

But again, it’s worth reminding ourselves of the facts: there has been a 92% decline in the per decade death toll from natural disasters since its peak in the 1920s. In that decade, 5.4 million people died from natural disasters. In the 2010s, just 0.4 million did. Globally, the five-year period ending in 2020 had the fewest natural disaster deaths of any five-year period since 1900. And this decline occurred during a period when the global population nearly quadrupled — and temperatures rose more than 1°C degree centigrade above pre-industrial levels.

The climate moaners need to get some perspective from history

by Ian Plimmer, Nov 4, 2021, SpectatorAustralia


Greta Thunberg rejects all ideas of the enlightenment. Despite what she wails, she is now living in the best times ever to be a child on planet Earth. She can actually go to FLOP26, something that few of us would want to do. Would she prefer to live in the worst of times when there was panic, suffering, environmental damage, death and no hope which she claims exists today?  

We now eat better, are less affected by natural disasters and are able to cope with extremes of weather and climate. During the last 4 of at least 20,000 generations of humans, child mortality has decreased and global human longevity increased from 25 to 79 years. The climate moaners need to get some perspective from history. 

The worst years to live since the time of Jesus were 535-550 AD because massive volcanic eruptions, perhaps Kamchatka or Alaska in 535-536 AD and Ilopango in El Salvador from 539-540 AD. The Northern Hemisphere atmosphere with filled with dust and acid sulphate clouds. These volcanic eruptions were coincidental with extraterrestrial impacts in March 536 AD in the Gulf of Carpentaria and elsewhere in August 536 AD. To make matters worse, these were at the time of a Solar Minimum. 

The Sun was dimmed for 18 months, a white sulphuric acid aerosol cloud enveloped Europe, global temperature dropped by 1.5 to 2.5°C producing worldwide crop failures and death by starvation. There was migration (e.g. Slavic speaking people), political turmoil and the collapse of empires (e.g. Sasanian Empire in Persia). Tree rings show almost no growth for a few years.

55 New Coal Power Stations Under Construction In India

by P. Homewood, Nov 4, 2021 in NotaLotofPeopleKnowThat


Last year, wind and solar only produced 7.7% of India’s electricity. Coal on the other hand provided 72.1%.

12 GW of new wind and solar capacity have been added in the last 12 months, the equivalent of 16 TWh a year.  However overall electricity consumption has been increasing at a rate of about 60 TWh a year, which means that coal generation will need to supply most of the gap..

This is a similar situation to China, where the construction of wind and solar farms cannot keep up with rising demand.

In FY 2020/21, a further 4.9 GW of thermal capacity (nearly all coal) was added, increasing existing capacity by 2%. This should generate about 30 TWh a year.

A Theory of the Hack

by S. McIntyre, Nov 1, 2021 in ClimateAudit


Two major new BBC programs, The Trick and the Hack That Changed The World, re-visit 2009 Climategate events on the eve of UK hosting the most recent international climate get-together. I was interviewed by The Hack and mentioned in The Trick as a villain.

In today’s article, I’m going to propose a theory of the Climategate hack that is very different from the grandiose conspiracy of Russian intel services and US fossil fuel corporations that is the prevalent fantasy of the climate “community” and chattering classes. Subsequent to my interview with the Hack That Changed, I’ve re-examined and cross-checked documents and noticed some interesting new connections. I don’t know the identity of the Climategate hacker, but do believe that deductions about his profile (e.g. motivated individual vs paid institutional hacker) can be made more intelligently by carefully examining details of what was exfiltrated and when – as I shall do here.

 

‘Guess the climate rules don’t apply to them’

by P. Homewood, Nov 2, 2021 in NotaLotofPeopleKnowThat


Bill Gates and Jeff Bezos were slammed as hypocrites for lecturing the world on the need to combat climate change by reducing carbon footprint while at the same time reportedly vacationing on superyachts off the coast of Turkey.

Multi-billionaire and Microsoft founder Gates celebrated his 66th birthday in Turkey in the company of fellow tycoon and Amazon founder Bezos on Friday.

Bezos was among the 50 guests invited to Gates’ private party beside the Mediterranean. It’s not clear whether any of Gates’ family helped him celebrate at his exclusive bash.

Gates – once the richest man on earth who has dropped to fourth on the Forbes Rich List ranking with $124 billion – transported his guests by helicopter from his $2million-a-week rental yacht ‘Lana’ to the Sea Me Beach club in Fethiye.

The jet fuel used to power helicopters emits 21.095 pounds of carbon dioxide per gallon burned, and helicopters travel approximately 10.75 miles per gallon.

According to reports, Bezos also travelled to Gates’ superyacht by helicopter.

The Blue Origin founder is said to have made the 120-mile round trip journey by chopper from Govoka to the resort town of Fethiye.

Based on the same estimations, Bezos’ helicopter emitted some 215 pounds of carbon dioxide into the atmosphere.

Both Bezos and Gates are reportedly staying on superyachts – each of which emits 7,020 tons of carbon dioxide per year, or 19 tons per day.

The Decline, the Stick and The Trick – Part 1uydi

by S. McIntyre, Nov 2, 2021 in ClimateAudit


One of the central claims of The Trick, if not the most central claim, was that “hiding the decline” was nothing more than an inopportune phrase about a single diagram.

It wasn’t.

The “trick to hide the decline” was an inopportune, if revealing, phrase, but rather than the issue being limited to a single diagram, the inconsistency between the Decline (in observed tree ring widths and densities) and the Hockey Stick temperature reconstructions (primarily based on tree ring widths) was, together with the looting of the Baghdad Museum, the issue that inspired my original examination of Michael Mann’s Hockey Stick and was the driving theme of Climate Audit from its origin up to Climategate.  There are dozens, even hundreds, of Climate Audit articles that, in one way or another, relate back to the conundrum arising from the inconsistency of the underlying proxies and the superficial consistency of the reconstructions.

In this and a couple of follow-on articles, I’ll illustrate the centrality of The Decline vs The Stick in the controversies in the years prior to Climategate.  For the benefit of people that may be new to these disputes, I re-iterate that I never interpreted the late 20th century decline in ring widths as evidence of a decline in temperatures, but as a seriously problematic inconsistency for “reconstructions” relying in large part on tree rings.

April 2003

When I say that the Decline inspired my original examination of Michael Mann’s Stick, it is literally true.

I had become mildly interested in climate issues in late 2002 when the Canadian government was promoting the Kyoto treaty, including in its promotion the assertion that 1998 was the “warmest year” in 1000 years.  This was based on the 2001 IPCC Assessment Report, which included multiple versions of the Hockey Stick graph, one of which was the following:

The Climate Is Changing, And Human Activities Are The Cause”: How, Exactly, Do We Know That?

by F. Menton, Oct 28, 2021 in WUWT


“The climate is changing, and we are the cause.” That is a statement that is so often-repeated and affirmed that it goes way beyond mere conventional wisdom. Probably, you encounter some version or another of that statement multiple times per week; maybe dozens of times. Everybody knows that it is true! And to express disagreement with that statement, probably more so than with any other element of current progressive orthodoxy, is a sure way to get yourself labeled a “science denier,” fired from an academic job, or even banished from the internet.

The UN IPCC’s recent Sixth Assessment Report on the climate is chock full of one version after another of the iconic statement, in each instance of course emphasizing that the human-caused climate changes are deleterious and even catastrophic. Examples:

  • Human influence has likely increased the chance of compound extreme events since the 1950s. This includes increases in the frequency of concurrent heatwaves and droughts on the global scale (high confidence); fire weather in some regions of all inhabited continents (medium confidence); and compound flooding in some locations (medium confidence). (Page A.3.5)
  • Event attribution studies and physical understanding indicate that human-induced climate change increases heavy precipitation associated with tropical cyclones (high confidence) but data limitations inhibit clear detection of past trends on the global scale. (Page A.3.4, Box TS.10)
  • Some recent hot extreme events would have been extremely unlikely to occur without human influence on the climate system. (Page A.3.4, Box TX.10)

So, over and over, it’s that we have “high confidence” that human influence is the cause, or that events would have been “extremely unlikely” without human influence. But how, really, do we know that? What is the proof?

This seems to me to be rather an important question. After all, various world leaders are proposing to spend some tens or hundreds of trillions of dollars to undo what are viewed as the most important human influences on the climate (use of fossil fuels). Billions of people are to be kept in, or cast into, energy poverty to appease the climate change gods. Political leaders from every country in the world are about to convene in Scotland to agree to a set of mandates that will transform most everyone’s life. You would think that nobody would even start down this road without definitive proof that we know the cause of the problem and that the proposed solutions are sure to work.

If you address my question — what is the proof? — to the UN, they seem at first glance to have an answer. Their answer is “detection and attribution studies.” These are “scientific” papers that purport to look at evidence and come to the conclusion that the events under examination, whether temperature rise, hurricanes, tornadoes, heat waves, or whatever, have been determined to be “attributed” to human influences. But the reason I put the word “scientific” in quotes is that just because a particular paper appears in a “scientific” journal does not mean that it has followed the scientific method.

The UN IPCC’s latest report, known as “Assessment Report 6” or “AR6,” came out in early August, loaded up, as already noted, with one statement after another about “high confidence” in attribution of climate changes and disasters to human influences. In the couple of months since, a few statisticians who actually know what they are doing have responded. On August 10, right on the heels of the IPCC, Ross McKitrick — an economist and statistician at the University of Guelph in Canada — came out with a paper in Climate Dynamics titled “Checking for model consistency in optimal fingerprinting: a comment.” On October 22, the Global Warming Policy Foundation then published two Reports on the same topic, the first by McKitrick titled “Suboptimal Fingerprinting?”, and the second by statistician William Briggs titled “How the IPCC Sees What Isn’t There.” (Full disclosure: I am on the Board of the American affiliate of the GWPF.).

Asia Building Hundreds Of Coal Power Plants

by P. Homewood, Oct 29, 2021 in NotaLotofPeopleKnowThat


UDANGUDI, India/TOKYO, Oct 29 (Reuters) – On the coastline near India’s southern tip, workers toil on a pier carrying a conveyor belt that cuts a mile into the Indian Ocean where the azure waters are deep enough for ships to berth and unload huge cargoes of coal.

The belt will carry millions of tonnes of coal each year to a giant power plant several kilometres inland that will burn the fuel for at least 30 years to generate power for the more than 70 million people that live in India’s Tamil Nadu state.

The Udangudi plant is one of nearly 200 coal-fired power stations under construction in Asia, including 95 in China, 28 in India and 23 in Indonesia, according to data from U.S. nonprofit Global Energy Monitor (GEM).

This new fleet will produce planet-warming emissions for decades and is a measure of the challenge world leaders face when they meet for climate talks in Glasgow, where they hope to sound the death knell for coal as a source of power.

Coal use is one of the many issues dividing industrialised and developing countries as they seek to tackle climate change.

Many industrialised countries have been shutting down coal plants for years to reduce emissions. The United States alone has retired 301 plants since 2000.

But in Asia, home to 60% of the world’s population and about half of global manufacturing, coal’s use is growing rather than shrinking as rapidly developing countries seek to meet booming demand for power.

More than 90% of the 195 coal plants being built around the world are in Asia, according to data from GEM.

Tamil Nadu is India’s second-most industrialised state and is one of the country’s top renewable energy producers. But it is also building the most coal-fired plants in the country. read more

“We cannot depend on just solar and wind,” a senior official at Tamil Nadu Generation and Distribution Corp told Reuters.

“You can have the cake of coal and an icing of solar,” he said, declining to be named as he was not authorised to speak to media.

Skeptics to attend UN summit in Scotland – Will praise Greta’s ‘Blah Blah Blah’ view of UN’s futile climate summits

by Marc Morano, Oct 28, 2021 in ClimateDepot


Climate Depot’s Marc Morano and a contingent of climate skeptics will descend upon the UN climate summit in Glasgow Scotland next week. The climate skeptics will be joining a growing coalition of climate activists who realize that UN summits are meaningless and will support the accurate claims of Schwarzenegger, Greta, Kerry, Hansen and others.

’30 years of blah blah blah’: Thunberg (correctly) questions value of climate talks – Greta: “There is no Planet Blah. Blah, blah, blah, blah, blah, blah.” … “Net zero, blah, blah, blah. Climate neutral, blah, blah, blah. This is all we hear from our so-called leaders — words, words that sound great but so far, has led to no action or hopes and dreams. Empty words and promises.”

Watch: Greta is right! Climate Summits are “blah blah blah.” – Morano Minute E19

John Kerry again admits climate futility: If U.S. & China ‘could go to zero (CO2 emissions) tomorrow… the world would still have a problem’

Flashback: Kerry admits zero emissions in US wouldn’t make difference in climate change

Flashback 2015: Then Sec. of State John Kerry explains climate futility: If U.S. zeroed out CO2 emissions, it ‘still wouldn’t be enough to offset the carbon pollution coming from the rest of the world’

‘Fraud, Fake…Worthless Words’: NASA’s James Hansen on UN Paris Pact – “[The Paris agreement] is a fraud really, a fake…It’s just worthless words. There is no action, just promises. As long as fossil fuels appear to be the cheapest fuels out there, they will be continued to be burned.” 

2019: UN Paris Climate Accord debunked by former UN IPCC chair Bob Watson – ‘Insufficient to address climate change’

Climate movement grandpa James Hansen declares the Green New Deal is ‘nonsense’ – ‘We need a real deal which understands how economics works’

2019: Progressive feminist Naomi Wolf rips the Green New Deal as ‘fascism’ – ‘I WANT a Green New Deal’ but ‘this one is a straight up power grab’

2021: MIT climate scientist Dr. Richard Lindzen: “Increasing emissions from China, India, and the rest of the developing world swamp the small reductions in the Anglosphere and the European Union. Indeed, if emissions from the Anglosphere and the EU were to cease (which is, of course, an impossibility), it would make little difference.

Saving the Earth — again?! 

The United Nations admitted that the much-hailed 2015 “historic” UN Paris climate pact did not “save” the planet and is instead “not enough” to prevent a climate change catastrophe! Despite being praised by former Vice President Al Gore, former Sec. of State John Kerry and many others, it appears the UN is demanding even more climate “action” to address what it claims is a climate problem.

Flashback 2019: UN admits ‘historic’ Paris climate pact did not save Earth after-all! Now says: Cutting CO2 ‘not enough’

UN in 2019: We must change food production to save the world, says leaked report – Cutting carbon from transport and energy ‘not enough’ IPCC finds

New Data Suggest Greenland’s Relative Sea Levels Were 6 Meters Higher 1,500-2,000 Years Ago

by K. Richard, Oct 28, 2021 in NoTricksZone


The discovery of whale bones and marine shells at ancient beach sites 32 to 36 meters above today’s shorelines have been dated to the Early to Middle Holocene. Beach ridges were still several meters higher than today during Roman and Medieval times.

The relative sea levels of the ancient past can be discerned by identifying the span of years marine shells were deposited on ancient beaches. Also, whales were as likely to wash up on shore thousands of years ago as they do today.

A new study (Souza et al., 2021) uses an alternative dating method to identify when beach ridge systems were still collection sites for sea shells along the west coast of Greenland (Disko Island). The authors find it “particularly interesting” that beach ridges were still elevated ~6 meters above modern sea levels less than 2,000 years ago, as previous studies have suggested the Disko Bay region’s sea levels should have fallen to below present sea level by this time.

The authors also determined the marine shells located 32 meters above present Disko Island shorelines can be dated to about 5,300 years ago. Whale carcasses collected at sites elevated 36 meters above modern have been dated to the Early Holocene.

The highest sea levels of the Holocene, or the Holocene Marine Limit, has been dated to ~9000 years ago. At that time deposits of sea shells on the southwest coast of Disko were as much as “~70 to 80 m above present sea level.”
