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.”

New Northern North Atlantic Study Finds The Coldest Period With The Most Sea Ice Of The Last ~85 Years…Is Today

by K. Richard, August 24, 2020 in NoTricksZone

Ecological conditions for 3 temperature- and sea ice-sensitive species show the sub-Arctic North Atlantic has been cooling and gaining ice since 1940.

In recent months, several scientific publications have documented a dramatic cooling trend in the subpolar North Atlantic, with temperatures plummeting 2°C since 2008 (Bryden et al., 2020) or -0.78°C per decade since 2004 (Fröb et al., 2019). Maroon et al. (2020) even point out 2015 was the coldest of the last 100 years.

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.

Fossil leaves show high atmospheric carbon spurred ancient ‘global greening’ Charles Rotter / 3 days ago August 20, 2020

by EARTH INSTITUTE AT COLUMBIA UNIVERSITY, August 20, 2020 in WUWT

Scientists studying leaves from a 23-million-year-old forest have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, and the hot climate off the time. The finding adds to the understanding of how rising CO2 heats the earth, and how the dynamics of plant life could shift within decades, when CO2 levels may closely mirror those of the distant past.

Scientists retrieved the leaves from a unique onetime New Zealand lake bed that holds the remains of plants, algae, spiders, beetle, flies, fungi and other living things from a warm period known as the early Miocene. Scientists have long postulated that CO2 was high then, and some plants could harvest it more efficiently for photosynthesis. This is the first study to show that those things actually happened in tandem. The findings were published this week in the journal Climate of the Past.

“The amazing thing is that these leaves are basically mummified, so we have their original chemical compositions, and can see all their fine features under a microscope,” said lead author Tammo Reichgelt, an adjunct scientist at Columbia University’s Lamont-Doherty Earth Observatory and assistant professor of geosciences at the University of Connecticut. “Evidence has been building that CO2 was high then, but there have been paradoxes.”

Le Précambrien : les bactéries, la tectonique des plaques et l’oxygène

by A. Préat (.pdf), 21 août 2020 in Bull.Séanc.Acad.R.Sci.OutreMer

 Mots-clés. — Écosystèmes microbiens; Isotopes du carbone et du soufre; Oxydoréduction; Oxygène; Océans et atmosphère. 

Résumé. — L’oxygène n’est pas apparu aussi brutalement qu’on le pensait sur notre planète. Malgré un apport en oxygène lié aux cyanobactéries dès l’archéen, ce ne sont pas ces microorganismes qui sont à la base de la première grande «révolution» de l’oxygène qui a eu lieu à la limite archéen/paléoprotérozoïque (il y a deux milliards et demi d’années) dans l’atmosphère, lors du Grand Événement d’Oxydation. Ce sont les processus liés au cycle de la tectonique des plaques (activité mantellique et périodes intenses d’érosion/altération) qui ont contribué de manière déterminante à l’augmentation de la concentration de l’oxygène atmosphérique voici deux milliards et demi d’années. Les deux principaux processus responsables de cette augmentation sont liés à l’enfouissement de la matière organique et de la pyrite. L’altération des séries riches de ces deux composants conditionnera ensuite pendant près d’un milliard d’années la composition chimique des océans en oxygène, soufre et fer. Au cours du temps, l’oxygène proviendra de l’activité des cyanobactéries et l’atmosphère réductrice du début de l’archéen sera remplacée par une atmosphère oxydante à la fin du précambrien. 

Keywords. — Microbial Ecosystems; Carbon and Sulfur Isotopes; Oxidation Reduction; Oxygen; Oceans and Atmosphere. 

Summary. — The Precambrian: Bacteria, Plate Tectonics and Oxygen. — Oxygen did not appear as abruptly as we thought on our planet. Despite an oxygen supply related to cyanobacteria since the Archean, these microorganisms are not at the origin of the first great oxygen revolution that took place at the Archean/Paleoproterozoic boundary (two and a half billion years) in the atmosphere during the Great Oxidation Event. Two processes related to the cycle of plate tectonics (mantle activity and intense periods of erosion/weathering) were mostly involved in the increase of the atmospheric oxygen concentration two and a half billion years ago. These two main processes are related to the burial of organic matter and pyrite. The alteration of series with high contents of these two elements will then condition for nearly one billion years the oxygen, sulfur and iron chemical composition of the oceans. Oxygen will finally come from the activity of cyanobacteria and the early Archean reducing atmosphere will be replaced by an oxidizing atmosphere at the end of the Precambrian. 

…

Fig. 3. — Évolution des compositions chimiques et des organismes des océans en trois phases majeures. À l’archéen, les océans contiennent peu d’oxygène et sont relativement riches en fer (colonne de gauche), alors que dans les océans modernes (colonne de droite) l’oxygène est abondant et le fer en quantité limitée. Entre ces deux phases, un long intervalle d’un peu plus d’un milliard d’années est caractérisé par des océans avec des concentrations modérées d’oxygène en surface et des eaux plus profondes riches en H2S en présence de quantités limitées de fer, de molybdène et d’autres éléments en traces importants dans les cycles biologiques. La colonne centrale représente l’«Océan de Canfield» et caractérise le Boring Billion. L’H2S produit (suite à la présence des sulfates, cf. texte) réagit avec le fer ferreux pour former la pyrite. Le fer ferreux n’est donc pas consommé par l’oxygène durant cet intervalle de temps, mais par l’H2S. L’Événement Lomagundi-Jatuli a lieu à environ 2,1 Ga dans le GOE (Great Oxidation Event), marqué par une très forte production d’oxygène. Le début du GOE est marqué par l’oxydation de la pyrite sur les cratons et la disparition des minéraux détritiques sensibles aux conditions d’oxydoréduction des éléments chalcophiles ou sidérophiles (uraninite, sidérite, pyrite, molybdénite, etc.). Les deux grands épisodes «Terre Boule de Neige» à 2,3 Ga («Glaciation Makganyena») et 0,635 («Glaciation Marinoenne»), et d’autres événements glaciaires moins importants ne sont pas reportés ni discutés dans le texte (modifié d’après Knoll 2003).

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’

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:

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.

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].

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

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:

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