Astrophysicist Asserts The Globe Will Cool ~1°C During 2020-2053 Due To An Oncoming Grand Solar Minimum

by K. Richard, August 27, 2020 in NoTricksZone


During the last Grand Solar Minimum (17th century), global surface temperatures dipped to the coldest of the last 10,000 years – about 1.4°C colder than today. Dr. Zharkova, an astrophysicist, has determined another imminent drop in solar activity will lead to a 1°C cooling in the coming decades.

From 1645 to 1710, the Sun went into a quiet phase referred to as the Maunder Minimum. During this period, the “surface temperature of the Earth was reduced all over the Globe” (Zharkova, 2020). Cold summers and winters ensued, with glaciers extending onto farmland, sea ice expanding beyond the Arctic, and “frost fairs” on frozen rivers in Europe.
                                                                                                                                                       .
The coldest temperatures and most expansive ice extent (glaciers,  permafrost, sea ice) of the last 10,000 years occurred during both this period and the surrounding centuries – often referred to as the Little Ice Age (LIA) (Glazer et al., 2020Geirsdottir et al., 2019).

In a new paper, Dr. Valentina Zharkova asserts that during solar cycles 25-27, the Sun may return to a modern Maunder-like Grand Solar Minimum. This solar quiet phase is expected to substantially reduce the Earth’s solar magnetic field, which will, in turn, lead to an increase in cosmic rays extending into Earth’s atmosphere and thus an increase in high clouds reflecting the Sun’s radiation back to space.

The consequence? A reduction in global temperatures to just 0.4°C above what they were in 1710.

The role of atmospheric CO2 as a temperature-driving mechanism is not mentioned in the paper.

PBS Blames Hurricanes, Wildfires On Climate Change, Defying UN ‘Consensus’

by H.S. Burnett, August 20, 2020 in ClimateChangeDispatch


PBS News Hour attacked climate science this weekend, publishing alarmist claims about hurricanes and wildfires that defy findings of the United Nations Intergovernmental Panel on Climate Change (IPCC).

In an interview between PBS reporter Hari Sreenivasan and Andrew Freedman, editor of Washington Post’s Capital Weather Gang, the two journalists blamed global warming for severe wildfires and hurricanes.

According to the IPCC, however, there is little or no evidence indicating global warming is impacting hurricanes or drought.

Stop Blaming Climate Change For California’s Fires–Michael Schellenberger

by P. Homewood, August 26, 2020 in NotaLotofPeopleKnowThat


It’s Not About The Climate

Nobody denies climate change is occurring and playing a role in warmer temperatures and heatwaves. Keeley notes that, since 1960, the variation in spring and summer temperatures explain 50% of the variation in fire frequency and intensity from one year to the next.

But the half-century since 1960 is the same period in which the U.S. government promoted, mostly out of ignorance, the suppression of regular fires which most forests need to allow for new growth.

For much of the 20th Century, U.S. agencies and private landowners suppressed fires as a matter of policy. The results were disastrous: the accumulation of wood fuel resulting in fires that burn so hot they sometimes kill the forest, turning it into shrubland.

The US government started to allow forests in national parks to burn more in the 1960s, and allowed a wider set of forests on public lands to burn starting in the 1990s.

“When I hear climate change discussed it’s suggested that it’s a major reason and it’s not,” Scott Stevens of the University of California, Berkeley, told me.

Redwood forests before Europeans arrived burned every 6 to 25 years. The evidence comes from fire scars on barks and the bases of massive ancient trees, hollowed out by fire, like the one depicted in The New York Times photograph.

“There was severe heat before the lightning that dried-out [wood] fuel,” noted Stevens. “But in Big Basin [redwood park], where fire burned every seven to ten years, there is a high-density of fuel build-up, especially in the forests.”

AUSTRALIA RECORDS ITS MOST SNOWFALL EVER OUTSIDE OF AN ALPINE AREA

by Cap Allon, August 25, 2020 in Electroverse


Antarctic air reaching Australia’s south east triggered snowfall down to low-lying regions across several states over the weekend and into Monday, with many people temporarily escaping house-arrest to enjoy the “once-in-a-15-year” event.

Heavy snow made for treacherous driving conditions near Old Adaminaby [Aug 23, 2020].

 

The town of Oberon received a record-breaking 20 cm (8 inches) of global warming goodness, the highest 24-hour snow total ever recorded outside of an Aussie alpine region. Traffic, predictably, was soon bumper-to-bumper through Hampton as tourists descended on Oberon to enjoy the snow–much to the chagrin of the local sheep. One Oberon resident reportedly bleated: “Let’s all go mingle with people from hot spots then risk taking something home. It will be so worth it.” And another jumbuck added: “I wonder what part of STAY AT HOME do all those idiots not understand.”

Scientists: It’s ‘Impossible’ To Measure Critical Cloud Processes…Observations 1/50th As Accurate As They Must Be

by K. Richard, August 20, 2020 in NoTricksZone


Clouds dominate as the driver of changes in the Earth’s radiation budget and climate. A comprehensive new analysis suggests we’re so uncertain about cloud processes and how they affect climate we can’t even quantify our uncertainty. 

According to scientists (Song et al., 2016), the total net forcing for Earth’s oceanic atmospheric greenhouse effect (Gaa) during 1992-2014 amounted to -0.04 W/m² per year. In other words, the trend in total longwave forcing had a net negative (cooling) influence during those 22 years despite a 42 ppm increase in CO2. This was primarily due to the downward trend in cloud cover that overwhelmed or “offset” the longwave influence from CO2.

Cloud impacts on climate are profound – but so are uncertainties

The influence of clouds profoundly affects Earth’s radiation budget, easily overwhelming CO2’s impact within the greeenhouse effect. This has been acknowledged by scientists for decades.

Despite the magnitude of clouds’ radiative impact on climate, scientists have also pointed out that our limited capacity to observe or measure cloud effects necessarily results in massive uncertainties.

For example, Stephens et al. (2012) estimated the uncertainty in Earth’s annual longwave surface fluxes is ±9 W/m² (~18 W/m²) primarily due to the uncertainties associated with cloud longwave radiation impacts.

Why Earth Overshoot Day And The Ecological Footprint Are Pseudoscientific Nonsense

by M. Schellenberger, August 23, 2020 in Forbes


Pour lire cet article en français, cliquez ici

Starting today through the end of the year, humankind will start consuming more resources than our planet can sustainably produce, according to the Global Footprint Network (GFN), which has been organizing such days since 1986.

“Humanity is using nature 1.75 times faster than our planet’s ecosystems can regenerate,” says the group. “This is akin to using 1.75 Earths.”

Rich nations “overshoot” their resources before poorer ones, according to GFN. The US, Australia, Denmark and Canada overshoot before the end of March, while Cuba, Nicaragua, Iraq, and Ecuador don’t overshoot until December.

“Earth Overshoot Day” is based on something called the “Ecological Footprint,” which is used by the World Wildlife Fund, the United Nations Environment Program, the United Nations Development Program’s Human Development Report, and the International Union for Conservation of Nature.

The Ecological Footprint has as much scientific merit as astrology, phrenology, and flat-earth theories. It’s time to treat the Ecological Footprint as the pseudoscientific theory it is.

Wildfires, Blackouts And High Gas Prices: Californians Fight Familiar Foes Amid Pandemic

by C. Rotter, August 20, 2020 in TheDailyCaller/WUWT


  • Wildfires are scorching California amid a massive heatwave, which is prompting citizens to consume more energy in hopes of staying cool. The increase in consumption resulted in rolling blackouts, as energy regulators managed an over-taxed energy grid. 
  • The wildfires and blackouts are also coming amid a severe economic downturn caused in part by government-imposed lockdowns designed to slow the spread of the coronavirus pandemic.
  • At the same time, a recent fuel tax increase is forcing Californians to pay more at the gas pump. California now has the highest gas prices in the country, data show.

ANTARCTIC FRONT TO DELIVER “ONE-IN-15-YEAR WEATHER EVENT” TO NEW SOUTH WALES

by Cap Allon, August 20, 2020 in Electroverse


People do the best they can with the information they have, but it appears to me, and Charles Bukowski, that the problem with the world is that the intelligent people are full of doubt, while the stupid people are full of confidence.

HEAVY SNOW is set to bury large swathes of NSW and the ACT over the next few days in what the Bureau of Meteorology is calling a “one-in-15-year weather event”, and what Electroverse posits is an addition to the ever-mounting pile of evidence which suggests anthropogenic global warming is a politicized, data-spun lie.

A large mass of Antarctic air is on course to blast the eastern half of Australia with blizzards, wild winds, and record-breaking low temperatures as it breaks-away from the ice continent and rides anomalously-far north on the back of a weak & wavy (meridional) jet stream (a phenomenon associated with the historically low solar activity we’re currently receiving).

Let’s Be Serious, More C02 Isn’t Making the Earth ‘Uninhabitable’

by  D. Simon, August 17, 2020 in RealClearMarkets


Former Federal Reserve Board Vice Chairman and Princeton University economist Alan Blinder recently wrote the following in the Wall Street Journal: “cumulative CO2 emissions heat up the atmosphere, causing climate changes of all sorts—most of them bad. Because this huge negative externality has been allowed to run rampant, we are gradually making the Earth an inhospitable place for humans.”

Increasing CO2 emissions have been “making the Earth an inhospitable place for humans?” Really?

A method has been developed to study extreme space weather events

by SKOLKOVO INSTITUTE OF SCIENCE AND TECHNOLOGY (SKOLTECH), August 15, 2020 in WUWT/Rotter


Scientists at Skolkovo Institute of Science and Technology (Skoltech), together with colleagues from the Karl-Franzens University of Graz & the Kanzelhöhe Observatory (Austria), Jet Propulsion Laboratory of California Institute of Technology (USA), Helioresearch (USA) and Space Research Institute of the Russian Academy of Sciences (Russia) developed a method to study fast Coronal Mass Ejections, powerful ejections of magnetized matter from the outer atmosphere of the Sun. The results can help to better understand and predict the most extreme space weather events and their potential to cause strong geomagnetic storms that directly affect the operation of engineering systems in space and on Earth. The results of the study are published in the Astrophysical Journal.

Coronal Mass Ejections are among the most energetic eruptive phenomena in our solar system and the main source of major space weather events. Huge clouds of plasma and magnetic flux are ejected from the atmosphere of the Sun into the surrounding space with speeds ranging from 100 to 3500 km/s. These gigantic solar plasma clouds and the accompanying powerful shock waves can reach our planet in less than a day, causing severe geomagnetic storms posing hazards to astronauts and technology in space and on Earth.

One of the strongest Space Weather events occurred in 1859 when the induced geomagnetic storm collapsed the whole telegraph system in North America and Europe, the main means of communication for business and personal contacts in those days.

“Low-Fact Propaganda”: Spiegel’s Alarmism Exposed (Again), Greenland Ice Not “Doomed”

by P. Gosselin, August 16, 2020 in NoTricksZone


German skeptic site Die Kalte Sonne here debunks a recent alarmist article appearing in Spiegel aimed at shocking its readers. The reality, it turns out, is not shocking at all.

Greenland ice doomed?

According to Spiegel, the Greenland ice sheet is already doomed (that is unless we skip the usual democratic process and just act immediately).

Spiegel claims Greenland “glaciers are continuously losing huge masses of ice” and that the system there is “dramatically off balance”. The leftist Hamburg-based weekly reported:

The melting of the glaciers on Greenland has apparently passed the point of no return. Even if the global rise in temperature were to stop immediately, the ice sheet would continue to retreat, report researchers led by Michalea King of Ohio State University report in the journal “Communications Earth and Environment“.

4°C warmer 11,000 years ago

But Die kalte Sonne wondered if this were really so, and needed only 2 mouse clicks to find a recent temperature reconstruction for Greenland’s past (Lecavalier et al. 2017, pdf here). The paper’s Figure 4a  shows the temperatures, with the temperature of 1950 at the far right which in paleo-climatology is always meant as “present”.

Thus, 11,000 years ago, it was up to 4°C warmer than in 1950 over long periods of thousands of years, and today the warming has been about 1°C since then. Since we can see an ice sheet of 2,850,000 km³ (that is roughly Gt) today, the “point of no return” cannot have been exceeded 10,000 years ago. How does the heading then come about? We take a look at the associated work by King et al. 2020:

Extensively-Referenced Study Of Past Scientists’ Global Temperature Estimates Suggests ‘No Change’ In 100 Years

by K. Richard, August 13, 2020 in NoTricksZone


In the early 1900s, the globally-averaged distribution of calculated surface temperature estimates ranged between 14 and 15°C. For 1991-2018, HadCRUT, Berkeley, and NASA GISS also estimate today’s global temperature is about 14.5°C.

Scientists estimating Earth’s surface temperature has been an ongoing pursuit since the early 19th century.

A new study (Kramm et al., 2020) suggests the generally agreed-upon global temperature from 1877 to 1913 from dozens of calculated results was about 14.4°C.

Problematically, HadCRUT, Berkley, and NASA GISS also indicate the 1991-2018 had a global surface temperature of about 14.5°C.

This would suggest there has been “no change in the globally averaged near-surface temperature over the past 100 years”.

Claim: Past evidence supports complete loss of Arctic sea-ice by 2035

by BRITISH ANTARCTIC SURVEY, August 3, 2020 in WUWT/Ch. Rotter


A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.

BRITISH ANTARCTIC SURVEY

A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.

High temperatures in the Arctic during the last interglacial – the warm period around 127,000 years ago – have puzzled scientists for decades. Now the UK Met Office’s Hadley Centre climate model has enabled an international team of researchers to compare Arctic sea ice conditions during the last interglacial with present day. Their findings are important for improving predictions of future sea ice change.

During spring and early summer, shallow pools of water form on the surface of Arctic sea-ice. These ‘melt ponds’ are important for how much sunlight is absorbed by the ice and how much is reflected back into space. The new Hadley Centre model is the UK’s most advanced physical representation of the Earth’s climate and a critical tool for climate research and incorporates sea-ice and melt ponds.

Using the model to look at Arctic sea ice during the last interglacial, the team concludes that the impact of intense springtime sunshine created many melt ponds, which played a crucial role in sea-ice melt. A simulation of the future using the same model indicates that the Arctic may become sea ice-free by 2035.

Joint lead author Dr Maria Vittoria Guarino, Earth System Modeller at British Antarctic Survey (BAS), says:

“High temperatures in the Arctic have puzzled scientists for decades. …

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.

1/ La crise ‘climatique du 20ème siècle

Il existe de nombreuses sources fournissant des historiques de température, mais il existe peu de séries chronologiques comparables à celle de l’Observatoire d’Armagh en Irlande du Nord pour la période 1796-2002 [5]; cette série est disponible sur le site web du Met Office britannique pour la période allant de 2002 à aujourd’hui [6].

Media Blame Isaias On Climate Change – As Hurricane Numbers Decline

by H.S. Burnett, August 10, 2020 in ClimateChangeDispatch


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.

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:

In addition, August 2020’s extent is currently greater than it was in the 1980s:

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.
