Climate alarmists take note: the ice locked within Antarctica is far more important to your hokey climate change theories than that which is contained in its northern cousin, the Arctic; the southern pole contains 90% of Earth’s ice.

According to official government data from the National Snow & Ice Data Center (NSIDC), 2020’s Antarctic Sea Ice Extent has been increasing rapidly this month, to levels rarely seen since record-keeping began 4+ decades ago.

The latest data-point –from day 241 (or Aug 28)– reveals extent is currently standing at 18.354 million km2, compared with the 1981-2010 ‘day 241’ average of 18.131 million km2 — and by my crude calculations, that’s an AGW-destroying 233,000 km2 more:

A new editorial paper has landed from professor Valentina Zharkova, entitled: “Modern Grand Solar Minimum will Lead to Terrestrial Cooling“. Published on August 4, 2020, Zharkova’s latest analysis suggests that June 8, 2020 was the date on which we entered the Modern (Eddy) Grand Solar Minimum.

The opening paragraph reads:

“In this editorial I will demonstrate with newly discovered solar activity proxy-magnetic field that the Sun has entered into the modern Grand Solar Minimum (2020–2053) that will lead to a significant reduction of solar magnetic field and activity like during Maunder minimum leading to noticeable reduction of terrestrial temperature.”

Another passage states:

“Currently, the Sun has completed solar cycle 24 – the weakest cycle of the past 100+ years – and in 2020, has started cycle 25. During the periods of low solar activity, such as the modern grand solar minimum, the Sun will often be devoid of sunspots. This is what is observed now at the start of this minimum, because in 2020 the Sun has seen, in total, 115 spotless days (or 78%), meaning 2020 is on track to surpass the space-age record of 281 spotless days (or 77%) observed in 2019. However, the cycle 25 start is still slow in firing active regions and flares, so with every extra day/week/month that passes, the null in solar activity is extended marking a start of grand solar minimum.”

What are the consequences for Earth of this decrease of solar activity?

“From 1645 to 1710, the temperatures across much of the Northern Hemisphere of the Earth plunged when the Sun entered a quiet phase now called the Maunder Minimum. This likely occurred because the total solar irradiance was reduced by 0.22%,” shown below (top graph); “that led to a decrease of the average terrestrial temperature measured mainly in the Northern hemisphere in Europe by 1.0–1.5°C,” also below (bottom graph):

Solar Cycle 25 may be spluttering into life, but all is once-again quiet on the earth-facing solar disc: there are no sunspots — in fact, there haven’t been any for the past 6 days (as of Aug 27, 2020).

Solar activity is the driving force of Earth’s climate. This definition of obvious is only disputed by the misinformed, and by those with a financial or political motive.

High solar activity — as we’ve enjoyed for the past 100-or-so years — has delivered our planet a stable, predictable climate under-which we modern humans have had the opportunity to thrive and successfully advance our technological society.

However, and as with all good things, these predictable days are ending: the Sun’s output is waning to levels not seen for the past 200 years, to a reduction in activity not experienced since the Dalton Minimum(1790-1830). And as with every great and advancing civilization of the past, a time comes when the consequences of a solar shutdown need to be contended. We need to prepare for the wild swings-between-extremes brought about by an increasingly weak & wavy (meridional) jet stream, we need to be aware of a powerful volcanic uptick witnessed during times of low solar activity, as well as cloud-nucleating Cosmic Rays, and, perhaps most crucially, an overall cooling of the planet.

Crops are always the first to go. And our modern delicately-balanced, chemical-dependent, monocropping-ways simply aren’t prepared for a violent shift in the climate — as Robert Felix has long been warning, “I fear that we will be fighting in the streets for food long before we’re covered by ice.”


When will Temperatures start to fall? Part1

by Tony Brown, August 28, 2020 in WUWT

“If Europeans truly mobilize around the delivery of the 2050 goal, every business decision, lifestyle choice, political swing, every hallmark of European culture — from annual ski trips, to Champions League Football matches, to French cheese — will need to be tested against its contribution to climate change.” European Commission ‘Green Deal’ March 2020

This is an article with a simple proposition.  Science tells us that rapidly rising Co2 in turn causes rising temperatures, which has become a very serious problem for humanity.

The three questions I ask, in the expectation that the answer can be provided from main stream published science is;

“Assuming we reach zero carbon emissions by 2030-Extinction Rebellion (XR) requirement,  or 2050 -the aim of most governments under the Paris Accord- 1) how long would it take for Co2 levels to naturally fall below the’ safe upper limits’ of 350ppm espoused by such as James Hansen; 2) for it to fall further to 280ppm -the previous pre industrial level -AND 3) when will temperatures start to fall in turn, to achieve pre industrial levels, said to be 1 to 2 degrees Centigrade below present, according to the IPCC.”

There are all sorts of caveats of course, with methane, water vapour, clouds, feedbacks, ocean response, natural variations etc but having scoured various ‘official’ web sites I can find no definitive estimate. An examination of the Extinction Rebellion web site demonstrates they are anarchists, rather than a serious green organisation. A couple of more reasoned attempts to track the consequences of zero carbon emissions are given in Note 3below the graphic-Figure 1 together with a variety of other useful background information.

Whether the reader personally believes excess Co2 to be a problem is not a matter this article is concerned with.  Let’s take science at face value –our respective Governments  have overwhelmingly agreed that humanity has added some 140ppm of Co2 to the pre industrial 280ppm and that, as a result, temperatures have risen substantially and are at a dangerous level and causing extremes of weather.

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

Cet article fait suite à la première partie (1/2) publiée par SCE le 14 août 2020.

5. La longueur des cycles solaires

Le passage d’un cycle solaire au cycle suivant est défini en principe par le changement de signe du champ magnétique autour des taches solaires. Le moment de ce passage est difficile à déterminer dans le cas des cycles longs, parce qu’on peut avoir pendant plusieurs années cohabitation, dans le même hémisphère solaire, de taches solaires d’orientations magnétiques différentes. Ainsi, à l’heure d’écriture de cet article (juillet 2020), la fin du cycle solaire 24 se rapproche, mais les premières taches avec l’orientation magnétique du cycle 25 ont fait leur apparition dès 2019; si  le cycle 24 n’était pas terminé avant la fin de cette année, la transition du cycle 24 au cycle 25 serait étalée sur 3 années.

De manière à tirer profit de la richesse des données disponibles sur le site (ici)  la longueur des cycles solaires est déterminée comme suit: pour les cycles allant de 1700 à 1755, seules les moyennes annuelles du nombre de taches solaires sont disponibles et le début de cycle correspond à l’année suivant le minimum de cette moyenne. Pour les cycles allant de 1755 à nos jours, la longueur est déterminée en utilisant les moyennes mensuelles: le début de cycle correspond au mois à partir duquel s’amorce la montée du nombre de taches. Cette méthode diffère de celle utilisée par Friis-Christensen et Lassen [29] et Butler et Johnston [30] qui ont travaillé par interpolation au départ des valeurs mensuelles lissées sur 13 mois.

Comme nous allons le voir, la longueur des cycles solaires varie de 9 ans minimum (cycles 2, 3 et 8) à 14 ans (cycle 4 marquant le début du Minimum de Dalton et la Révolution française). La Figure 5 fournit les longueurs des 29 cycles solaires observés depuis le début du 18ème siècle, chaque valeur étant positionnée au milieu du cycle correspondant.  La figure suggère que la dispersion des cycles solaires va diminuant du 18ème au 20èmesiècle: de manière à préciser cette impression, on calcule dans le tableau suivant, pour chacun des siècles considérés, les longueurs moyennes des cycles solaires (en années) et leurs déviations standard.

Figure 5 : Longueur des 29 cycles solaires observés du 18ème au 21ème siècle.

Le résultat le plus frappant de ce tableau est que les cycles solaires du  20ème siècle sont en moyenne un an plus courts que ceux du 19ème siècle, la tendance s’inversant avec les 2 premiers cycles du 21ème siècle. En appliquant la corrélation de Butler et Johnston [24], ceci rendrait le 20ème siècle plus chaud de 0,5°C en moyenne que le 19ème siècle.

New confirmation that climate models overstate atmospheric warming

by Dr. Judith Curry, August 27, 2020 in WUWT

Reposted from Dr. Judith Curry’s Climate Etc.

Posted on August 25, 2020

by Ross McKitrick

Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better.

The papers are Mitchell et al. (2020) “The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability” Environmental Research Letters, and McKitrick and Christy (2020) “Pervasive warming bias in CMIP6 tropospheric layers” Earth and Space Science. John and I didn’t know about the Mitchell team’s work until after their paper came out, and they likewise didn’t know about ours.

Mitchell et al. look at the surface, troposphere and stratosphere over the tropics (20N to 20S). John and I look at the tropical and global lower- and mid- troposphere. Both papers test large samples of the latest generation (“Coupled Model Intercomparison Project version 6” or CMIP6) climate models, i.e. the ones being used for the next IPCC report, and compare model outputs to post-1979 observations. John and I were able to examine 38 models while Mitchell et al. looked at 48 models. The sheer number makes one wonder why so many are needed, if the science is settled. Both papers looked at “hindcasts,” which are reconstructions of recent historical temperatures in response to observed greenhouse gas emissions and other changes (e.g. aerosols and solar forcing). Across the two papers it emerges that the models overshoot historical warming from the near-surface through the upper troposphere, in the tropics and globally.

Mitchell et al. 2020

Mitchell et al. had, in an earlier study, examined whether the problem is that the models amplify surface warming too much as you go up in altitude, or whether they get the vertical amplification right but start with too much surface warming. The short answer is both.

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.”

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.

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


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.


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


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.

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:
