The Tyranny Of Global Warmists Is Worse Than You Think

by D. Solway, August 11, 2020 in ClimateChangeDispatch

“The more one has paid for a forgery, the more one defends it in the face of all the evidence to the contrary,” writes John Le Carré in his novel about espionage and deception, Smiley’s People.

This certainly seems to be the case with the four major weather-tracking agencies: the Hadley Climate Research Unit in Britain, the Christy group at the University of Alabama, the Remote Sensing Systems Inc. in California, and the NASA Goddard Institute for Space Studies in New York (NASA GISS).

In a previous article for The Pipeline, I examined the malfeasance of the influential Hadley Climate Research Unit at the University of East Anglia in Norwich, where two major email dumps (aka “Climategate”) showed the outfit’s determined efforts to fudge the data, suppress unfavorable results and eliminate dissenting voices.

This should have put the “global warming” farce to bed once and for all, but the deception shows no sign of abating.

Le 20ème siècle a été anormalement chaud mais le 21ème siècle revient à la normale (1/2)

by Jean Van Vliet, 14 août 2020, in ScienceClimatEnergie

Introduction

Suite à la prise de conscience à la fin du 20ème siècle d’une hausse inhabituelle des températures terrestres, des chercheurs américains ont développé une théorie du réchauffement global basé sur l’effet de serre dû au CO2 [1], en soulignant la responsabilité possible de l’homme dans le réchauffement observé: la poursuite des émissions de CO2 conduirait à une éventuelle catastrophe planétaire. Ces  chercheurs ont présenté leur théorie au Congrès américain [2] et aux médias. Le monde politique international a réagi rapidement à cet alarmisme [3] en permettant à Assemblée Générale de l’ONU de décembre 1988 d’approuver la mise en place du GIEC [4].

Depuis plus de trente ans et malgré le manque persistant de preuve formelle, la peur du réchauffement global anthropique causé par le CO2 est propagée sans relâche par l’ONU et ses satellites PNUE, GIEC et OMM relayés par les ONG environnementales et les médias, suivis plus récemment par une fraction du monde académique occidental. Une puissante industrie des énergies renouvelables a été créée via des subsides et des certificats verts quitte à doubler ou tripler le prix de l’électricité. Cette industrie est prête à exploiter les nouvelles aubaines financières annoncées par l’Accord de Paris et le Green Deal de l’UE. Dans un tel contexte, le but avoué est que l’humanité change radicalement son comportement, fût-ce au prix d’une dictature environnementale: l’alarmisme médiatique est maximal, et même les enfants sont embrigadés dans le débat pour soi-disant “sauver la planète”.

Cette tentative rampante de prise du pouvoir a cependant buté contre un obstacle imprévu depuis le début de 2020, à savoir la pandémie du Coronavirus: le lockdown sanitaire a montré que la société pouvait changer son comportement de manière spectaculaire, mais au prix de conséquences économiques et sociales majeures. A la première attaque de la pandémie succède aujourd’hui une deuxième vague et il semble impossible de prévoir quand nous serons délivrés du virus.

Les ressources des Etats n’étant pas infinies, la question brûlante se pose aujourd’hui  de l’affectation des moyens humains et financiers disponibles en fonction nos priorités: devons-nous avoir davantage peur d’une pandémie et de ses conséquences sociales et économiques incontestables ou devons-nous supputer une explosion incontrôlable de la crise climatique amorcée au 20ème siècle et modifiant de manière drastique et irréversible notre environnement ?

Le but du présent article est d’apporter des éléments de réponse à cette question en examinant, dans une perspective scientifique large et basée sur les observations plutôt que sur les modèles, la “crise climatique” démarrée durant la seconde moitié du 20ème siècle en essayant de tirer des conclusions applicables au 21èmesiècle.

Greta Thunberg’s Message Of Doom Is Religion, Not Reality

by I. Martin, August 10, 2020 in ClimateChangeDispatch

In January, the great and not so good of the corporate elite gathered at Davos for another telling off from Greta Thunberg.

“One year ago I came to Davos and told you that our house is on fire,” the climate activist reminded delegates. “I said I wanted you to panic.” In the intervening year they had not panicked enough, she said.

Although the meeting of the World Economic Forum was dedicated to creating a “Cohesive and Sustainable World”, and corporate culture has gone obsessively green, the naughty capitalists and greedy governments refused to end the use of fossil fuels instantly.

Media Blame Isaias On Climate Change – As Hurricane Numbers Decline

Hurricane Isaias hadn’t even made landfall in the United States before the media began proclaiming Isaias was the result of human-caused climate change.

Not only is there no evidence for such a claim, but hurricane numbers have been declining as global temperatures modestly warm.

Also, even the United Nations Intergovernmental Panel on Climate Change (IPCC) disputes any connection between global warming and hurricanes.

Large Increase In Number Of Sunshine Hours Likely Behind Warming, Glacier Retreat In Alps Since 1980

by P. Gosselin, August 9, 2020 in NoTricksZone

Today global warming alarmists insist blaming climate change on man-made CO2 emissions. Yet, everywhere we look it’s difficult to find any correlation between CO2 and warming. Pre-industrial history shows that changes in CO2 in fact followed temperature changes.

Today we look at some climate charts of the European upper Ostalpen to look for hints what may be behind the warming since the late 20th century. We know glaciers there have been receding over the recent decades.

First is a mean temperature chart of the region for the May to September period going back 133 years:

New Study: A Southern Ocean Site Has Just Cooled To Ice Age-Era Temperatures – 2°C Colder Than 20,000 Years Ago

by K. Richard, August 10, 2020 in NoTricksZone

A new temperature reconstruction indicates today’s sea surface temperatures are colder than all but a few millennia out of the last 156,000 years.

A Southern Ocean site analyzed in a new study (Ghadi et al., 2020) has averaged 1-2°C during glacials and 4°C during interglacials. Today, with a 410 ppm CO2 concentration, this location has again plummeted to glacial/ice age levels (2°C).

The site was 2°C warmer than now when CO2 concentrations were 180 ppm about 20,000 years ago, or during the peak of the last ice age. During the Early Holocene (10,000 to 8,000 years ago), summer sea surface temperatures were also 2°C warmer than today.

There is no indication that CO2 concentration changes are in any way correlated with temperature changes throughout this entire 156,000-year epoch.

New Study: Rising CO2 Drives Post-1980s Greening…Which Cools The Earth And Offsets 29% Of Human Emissions

by Haverd et al., 2020 in NoTricksZone/K. Richard

About 70% of the Earth’s post-1980s vegetative greening trend has been driven by CO2 fertilization. More greening has offset or reversed 29% of recent anthropogenic CO2 emissions. Greening also has a net cooling effect on surface temperatures.

Earlier this year we highlighted a study (Haverd et al., 2020) asserting rising CO2 and warming are the dominiant drivers of Earth’s strong post-1980s greening trend. This greening expands Earth’s carbon sink so profoundly that by 2100 the greening of the Earth will offset 17 years (equivalent) of anthropogenic CO2 emissions.

A 17% offset over 80 years, or net CO2 emissions reversal, would easily supplant the effectiveness of Paris climate accord CO2 mitigation policies.

…

Now another new study (Piaoet et al., 2020) expands upon these same principles, further suggesting the net effect of more CO2-driven greening is more cooling and carbon sink expansion.

Since the 1980s, 29% of human CO2 emissions were cancelled out by the CO2-induced greening of the Earth. The post-2000 vegetative greening expansion has been so massive (5.4 million km²) its net areal increase is equivalent to a region the size of the Amazon rainforest.

“Vegetation models suggest that CO2 fertilization is the main driver of greening on the global scale, with other factors being notable at the regional scale. Modelling indicates that greening could mitigate global warming by increasing the carbon sink on land and altering biogeophysical processes, mainly evaporative cooling.”

According to official government data from the National Snow & Ice Data Center (NSIDC), 2020’s Antarctic Sea Ice Extent is tracking the 1979-1990 average.

Climate alarmists take note, the ice locked within Antarctica is far more important to your hokey climate theories than that contained in its northern cousin the Arctic.

The Antarctic contains 90% of our planet’s ice, and, therefore, if Antarctica isn’t melting then any potential sea-level rise will be severely limited.

And Antarctica isn’t melting.

According to the latest NSIDC data, sea ice extent around the southern pole has been tracking the 1979-1990 average ALL YEAR:

Mercury Deposition, Climate Change and Anthropogenic Activities: A Review

by Li, F. et al. July 31, 2020 in Front. Earth.Sci.

As a toxic and harmful global pollutant, mercury enters the environment through natural sources, and human activities. Based on large numbers of previous studies, this paper summarized the characteristics of mercury deposition and the impacts of climate change and human activities on mercury deposition from a global perspective. The results indicated that global mercury deposition changed synchronously, with more accumulation during the glacial period and less accumulation during the interglacial period. Mercury deposition fluctuated greatly during the Early Holocene but was stable and low during the Mid-Holocene. During the Late Holocene, mercury deposition reached the highest value. An increase in precipitation promotes a rise in forest litterfall Hg deposition. Nevertheless, there is a paucity of research on the mechanisms of mercury deposition affected by long-term humidity changes. Mercury accumulation was relatively low before the Industrial Revolution ca. 1840, while after industrialization, intensive industrial activities produced large amounts of anthropogenic mercury emissions and the accumulation increased rapidly. Since the 1970s, the center of global mercury production has gradually shifted from Europe and North America to Asia. On the scale of hundreds of thousands of years, mercury accumulation was greater in cold periods and less in warm periods, reflecting exogenous dust inputs. On millennial timescales, the correspondence between mercury deposition and temperature is less significant, as the former is more closely related to volcanic eruption and human activities. However, there remains significant uncertainties such as non-uniform distribution of research sites, lack of mercury deposition reconstruction with a long timescale and sub-century resolution, and the unclear relationship between precipitation change and mercury accumulation.

During The Last Glacial Maximum Fires Were 10 Times More Common And Summer Temps 3-4°C Warmer Than Today

by K. Richard, August 3, 2020 in NoTricksZone

A new study finds that 26 to 19 thousand years ago, with CO2 concentrations as low as 180 ppm, fire activity was an order of magnitude more prevalent than today near the southern tip of Africa – mostly because summer temperatures were 3-4°C warmer.

We usually assume the last glacial maximum – the peak of the last ice age – was signficantly colder than it is today.

But evidence has been uncovered that wild horses fed on exposed grass year-round in the Arctic, Alaska’s North Slope, about 20,000 to 17,000 years ago, when CO2 concentrations were at their lowest and yet “summer temperatures were higher here than they are today” (Kuzmina et al., 2019). Horses had a “substantial dietary volume” of dried grasses year-round, even in winter at this time, but the Arctic is presently “no place for horses” because there is too little for them to eat, and the food there is to eat is “deeply buried by snow” (Guthrie and Stoker, 1990).

In a new study (Kraaij et al., 2020) find evidence that “the number of days per annum with high or higher fire danger scores was almost an order of magnitude larger during the LGM [last glacial maximum, 19-26 ka BP]  than under contemporary conditions” near Africa’s southernmost tip, and that “daily maximum temperatures were 3-4°C higher than present in summer (and 2-4°C lower than present in winter), which would have contributed to the high severity of fire weather during LGM summers.”

Neither conclusion – that surface temperatures would be warmer or that fires would be more common – would seem to be consistent with the position that CO2 variations drive climate or heavily contribute to fire patterns.

World’s Largest Meteorite

by Geology Page, January 8, 2017

Name: Hoba “This is an OFFICIAL meteorite name”
Abbreviation: There is no official abbreviation for this meteorite.
Observed fall: No
Year found: 1920
Country: Namibia
Mass: 60 tons

The Hoba or Hoba West meteorite lies on the farm “Hoba West”, not far from Grootfontein, in the Otjozondjupa Region of Namibia. It has been uncovered but, because of its large mass, has never been moved from where it fell. The main mass is estimated at more than 60 tons, making it the largest known meteorite (as a single piece) and the most massive naturally occurring piece of iron known on Earth’s surface.

Impact

The Hoba meteorite impact is thought to have occurred more recently than 80,000 years ago. It is inferred that the Earth’s atmosphere slowed the object to the point that it impacted the surface at terminal velocity, thereby remaining intact and causing little excavation.

Assuming a drag coefficient of about 1.3, the meteor would have been slowed to about 720 miles per hour (0.32 km/s) from its speed on entering the Earth’s atmosphere, typically in excess of 10 km/s for similar objects. The meteorite is unusual in that it is flat on both major surfaces, possibly causing it to have skipped across the top of the atmosphere like a flat stone skipping on water.

First Time In 70 Years No Pacific Typhoon Forms In July… Alarmists Alarmed Typhoon Trend Falling!

by P. Gosselin, Ausgust 1, 2020 in NoTricksZone

This year is the first time since 1951 the Pacific sees no typhoons in the month of July. Typhoons have seen downward trend since 1951. 

Global warming alarmists like to claim that tropical storms will intensify and become more frequent unless people stop using fossil fuels.

And recently these alarmists have had our attention steered to the Atlantic basin, where tropical storms this year have seen quite an active season thus far.

Another reason the focus has been on the Atlantic is because very little has been happening in terms of Pacific typhoons, and the alarmists don’t want to talk about that.

In fact this July is the first July to have seen no typhoons formed in the Pacific at all since statistics on this began in 1951, according to the data from the Japan Meteorological Agency (JMA).

Data source: JMA, here and here. 

Normally between 3 to 4 typhoons form in the Pacific in July. Up to 8 have formed in the past, e.g. on 2017 and 1971. But this year July failed to see a single typhoon form – the first time this has occurred since 1951.

Satellite survey shows California’s sinking coastal hotspots

by Arizona State University, August 2, 2020 in WUWT

A majority of the world population lives on low lying lands near the sea, some of which are predicted to submerge by the end of the 21st century due to rising sea levels.

…

The most relevant quantity for assessing the impacts of sea-level change on these communities is the relative sea-level rise – the elevation change between the Earth’s surface height and sea surface height. For an observer standing on the coastland, relative sea-level rise is the net change in the sea level, which also includes the rise and fall of the land beneath observer’s feet.

Now, using precise measurements from state-of-the-art satellite-based interferometric synthetic aperture radar (InSAR) that can detect the land surface rise and fall with millimeter accuracy, an Arizona State University research team has, for the first time, tracked the entire California coast’s vertical land motion.

They’ve identified local hotspots of the sinking coast, in the cities of San Diego, Los Angeles, Santa Cruz and San Francisco, with a combined population of 4 to 8 million people exposed to rapid land subsidence, who will be at a higher flooding risk during the decades ahead of projected sea-level rise.

“We have ushered in a new era of coastal mapping at greater than 1,000 fold higher detail and resolution than ever before,” said Manoochehr Shirzaei, who is the principal investigator of the NASA-funded project. “The unprecedented detail and submillimeter accuracy resolved in our vertical land motion dataset can transform the understanding of natural and anthropogenic changes in relative sea-level and associated hazards.”

The results were published in this week’s issue of Science Advances (DOI link here).

NASA “CLIMATE PROPHET” JAMES HANSEN SAID THE ARCTIC WOULD BE “FREE OF SUMMER ICE” BY 2018

by Cap Allon, August 2, 2020 in Electroverse

Bolstered by the sycophantic-praise he received following his 1988 Congressional testimony on man-made global warming, NASA climate scientist/activist James Edward Hansen continued his prophesies well into the 2000s–despite his ever-growing list of climate fails.

“The greenhouse effect is here,” pronounced doomsayer Hansen back on June 23, 1988.

“We’re [still] toast,” he repeated with a straight face 20 years later, in 2008.

in preparation for his 1988 Congressional testimony, scientists/activist Hansen produced three potential scenarios regarding the future trend for global average temperatures:

A) “Business As Usual” — if human’s did nothing regarding rising CO2 levels.

B) If we “moderately” reduced CO2 emissions.

C) If atmospheric carbon dioxide was reduced to year 2000 levels.

 

Real-world observations reveal Hansen’s projections were way off. Scenarios A and Bsignificantly over-predict the warming trend. And digging into the data, A overstates CO2 and other greenhouse gas growth and rejects against the observations; Scenario B slightly understates CO2 growth, overstates methane and CFCs and zeroes-out other greenhouse gas growth, and it too significantly overstates the warming.

The scenario that best-matches the observations is C — the one where Hansen has CO2 topping-out at 368 ppm in 2000 but then sees it fixed at that level thereafter–something that obviously didn’t happen. It’s this drastic “halt the industrial revolution” scenario that ended up with a warming trend most like the real-world observations.

Here is one thought, proposed by climate scientist John Christy:

Suppose Hansen had offered a Scenario D, in which greenhouse gases continue to rise, but after the 1990s they have very little effect on the climate. That would play out similarly in his modeled Scenario C, and it would match the data — this hypothetical Scenario D is the reality we’re living today.

James Edward Hansen is still considered a “climate prophet” by many, but his 1988 scenarios simply DO NOT FIT THE DATA–speaking of which, let’s look at his Arctic sea ice predictions.

A snapshot of melting Arctic sea ice during the summer of 2018

As sea ice in the Arctic retreats further and melts faster every decade, scientists are racing to understand the vulnerabilities of one of the world’s most remote and unforgiving places. A study appearing July 29 in the journal Heliyon details the changes that occurred in the Arctic in September of 2018, a year when nearly 10 million kilometers of sea ice were lost over the course of the summer. Their findings give an overview at different timescales of how sea ice has receded over the 40 years of the satellite era and show how the summer’s extensive decline is linked to global atmospheric processes as far south as the tropics.

At the peak of its melting season, in July 2018, the Arctic was losing sea ice at a rate of 105,500 square kilometers per day–an area bigger than Iceland or the state of Kentucky. “On the ground, I am sure it would have looked like an excellent summer month in the Arctic, in general, but over the past four decades, September sea-ice loss has accelerated to a rate of 12.8% per decade and 82,300 square kilometers per year,” says co-author Avinash Kumar, a senior scientist at the National Centre for Polar and Ocean Research (NCPOR) in India.

Data From 2 Independent Studies Show No Correlation Between CO2 And Temperature

by P. Gosselin, July 29, 2020 in NoTricksZone

German climatologist Professor Dr. Horst-Joachim Lüdecke recently took data from two independent studies and superimposed them. The result shows  the long claimed atmospheric CO2-global temperature correlation doesn’t exist. 

The first data set was global temperature anomaly going back 600 million years, taken from the results of a paper by Came and Veizer, appearing in Nature (2007) and plotted below (blue):

The second data set was of atmospheric CO2 going back 600 million years, taken from a published study by Berner (2003), also appearing in Nature. These data are plotted in the above chart in blue.

No correlation

The plots were combined in the above chart to see how well they correlated, if at all. The result: no correlation.

For example, as the chart shows, 150 million years ago the atmospheric CO2 concentration was over 2000 ppm, which is 5 times today’s atmospheric concentration of 410 ppm – a level that some climate scientists say is already “dangerously high”. Yet, the global temperature 150 million years ago was more than 2°C below the long-term mean.

450 million years ago the relationship was even far more on its head: atmospheric CO2 concentrations were more than 10 times today’s level, yet the global temperature was a frigid 3.5°C below the mean!

“There’s no correlation between earth temperature and CO2,” Prof. Lüdecke concludes, observing recorded data.

EARTH’S ATMOSPHERE HAS NO “WALLS” OR “LID” — GREENHOUSE GAS THEORY IS BOTH MATHEMATICALLY AND PHYSICALLY WRONG

by Cap Allon, July 30, 2020 in Electroverse

“The CO2 greenhouse effect of the Earth’s atmosphere is a pure fiction of people who like to use large computers, without physical bases.” — Gerhard Gerlich ph.D.

Over the years, scientific paper after scientific paper has contended the entire foundation of the man-made global-warming theory is wrong. However, those in control of the agenda selectively choose which papers/theories the public can hear about, and, in turn, which get swept under the rug.

One such paper the ill-informed street-sheep have likely never heard of is that published in the journal “Environment Pollution and Climate Change” back in 2017–the “door-opener to a new paradigm,” former IPCC reviewer Nils-Axel Mörner is quoted as calling it (Mörner left the UN after realizing it was not truly interested in science).

“New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Temperature Model” argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s temperature — it concludes the entire greenhouse gas theory is incorrect.

As reported by wnd.com, the prevailing theory on the earth’s temperature is that heat from the Sun enters the atmosphere, and then greenhouse gases such as CO2, methane, and water vapor trap part of that energy by preventing it from escaping back into space.

That theory, which underpins the anthropogenic global-warming hypothesis and the climate models used by the United Nations, was first proposed and developed in the 19th century.

New evidence that an extraterrestrial collision 12,800 years ago triggered an abrupt climate change for Earth

by C. Rotter, July 27, 2020 in WUWT

Christopher R. Moore, University of South Carolina

What kicked off the Earth’s rapid cooling 12,800 years ago?

In the space of just a couple of years, average temperatures abruptly dropped, resulting in temperatures as much as 14 degrees Fahrenheit cooler in some regions of the Northern Hemisphere. If a drop like that happened today, it would mean the average temperature of Miami Beach would quickly change to that of current Montreal, Canada. Layers of ice in Greenland show that this cool period in the Northern Hemisphere lasted about 1,400 years.

This climate event, called the Younger Dryas by scientists, marked the beginning of a decline in ice-age megafauna, such as mammoth and mastodon, eventually leading to extinction of more than 35 genera of animals across North America. Although disputed, some research suggests that Younger Dryas environmental changes led to a population decline among the Native Americans known for their distinctive Clovis spear points.

Peter Ridd loses, we all lose

by J. Marohasy, July 23, 2020 in TheSpectator

On 2 May 2018, Professor Peter Ridd was sacked by James Cook University for serious misconduct. It all started when he called-out his colleague Terry Hughes for falsely claiming healthy inshore coral reefs were dead from climate change and deteriorating water quality.

Ignoring the first censure in April 2016, Professor Ridd went on television in August 2017 and explained in an interview with Alan Jones and Peta Credlin why so much said and written about the Great Barrier Reef, including by scientists at the Australian Institution of Marine Science, is ‘untrustworthy’.

The interview was to promote a book that I edited, Climate Change: The Facts 2017. The book, published by the Institute of Public Affairs, begins with a chapter about the Great Barrier Reef in which the orthodoxy on Great Barrier Reef science is challenged, in particular reporting on coral calcification rates. In that interview – that contributed directly to Peter Ridd’s sacking – the main argument was, and continues to be, for better quality assurance of coral reef science.

It is a fact that the Australian Institute of Marine Science refuses to release 15 years of coral growth data – because it contradicts the claims of high-profile activists that coral growth rates are in decline. They are not. But the false claims are central to their fundraising strategy. Never mind the truth.

Greenpeace Cofounder: ‘There Is No Climate Catastrophe – It’s A Lie’

by 21Wire, July 24, 2020 in ClimateChangeDispatch

Power Hour host Alex Epstein  discusses the alleged ‘climate catastrophe’ with Dr. Patrick Moore, ecologist and co-founder of Greenpeace. 

Incredibly, Moore completely eviscerates the concept of “climate catastrophism,” and dismantles the claim that man-made CO2 levels are warming the planet beyond a tipping point of human survival.

Moore makes a number of strong arguments that debunk the IPCC’s increasingly problematic pseudo-scientific and anti-human narrative which is being parroted by climate change activists and the likes of Greta Thunberg.

He explains:

  • Why Moore left Greenpeace.

  • The beginnings of the climate catastrophe movement.

  • Why Moore believes human beings would not only survive but survive better at far higher average temperatures (which would be concentrated toward the poles).

  • Why Moore believes that contrary to being in a Sixth Extinction, we are actually at an unprecedented time of biodiversity with no end in sight.

  • Why Moore believes “ocean acidification” claims are totally meritless.

  • The commonality among the opposition to plastics, GMOs, nuclear energy, and fossil fuels.

  • Moore’s unrefuted theory that human beings actually saved life on Earth from a terminal decline in CO2 levels.

Modern Ancient Temperatures

by W. Eschenbach, July 24, 2020 in WUWT

OK, no need to torture me, I confess it—I’m a data junkie.

And when I see a new (to me at least) high-resolution dataset, my knees get weak. Case in point? The temperature dataset of the Colle Gnifetti ice core. It has a two-year resolution thanks to some new techniques. Better, it stretches clear back to the year 800. And best, it extends up to near the present, 2006. This lets us compare it to modern datasets. The analysis of the ice core dataset is described in Temperature and mineral dust variability recorded in two low-accumulation Alpine ice cores over the last millennium by Pascal Bohleber et al.

Let me start with where Colle Gnifetti is located. Unusual among ice core records, it’s from Europe, specifically in the Alps on the border of Switzerland and Italy.

Figure 1. Location of the ice cores in the study.

This is good because some of the longest thermometer-based temperature records are in Europe.

One interesting thing about the site is that usually, ice core drilling occurs at the literal ends of the earth, in Antarctica and Greenland and the like. But this site is not far from the foot of the Margherita Hut, which is at over 4500 metres elevation.

Settled Science? New Climate Study Shifts the Goalposts to 2.6-3.9C

by Eric Worall, July 24, 2020 in WUWT

A new climate study has dismissed utterly implausible high end climate models. But the new study also seeks to raise the low end of the range of estimated climate sensitivity into the discomfort zone.

…

The treatment of cloud feedback is interesting. The study acknowledges large cloud feedback uncertainties, mentions the Lindzen et al. (2001) “iris effect”, and admits GCMs cannot be trusted to reproduce observed cloud response, yet still appears to attempt to derive a cloud feedback factor based on satellite observations, and mix this observational cloud factor with model predictions.

The treatment of clouds may turn out to be one of the most controversial assumptions in the study – as Pat Frank has pointed out on a number of occasions, the magnitude of model cloud response error is significantly greater than the CO2 driven warming which models attempt to project, which calls into question whether climate models have any predictive skill whatsoever.

To the author’s credit they have described their method in great detail, so I’m looking forward to detailed responses to this study.
