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

Ten fat polar bears filmed raiding a stalled Russian garbage truck

by Siberian Times, Oct 21, 2020 in WUWT/Ch.Rotter

From the Siberian Times today (20 October) is a story with few facts but a fabulous video of six fat adults and four fat cubs as they set siege to a stalled open garbage truck in the Russian Arctic. It may have been filmed on Novaya Zemlya but that has not been confirmed.

Of course, Novaya Zemlya has had previous problems with bears habituated to garbage, most famously an extended incident in 2019 that was perversely blamed on climate change.

There were two families that I could see in the video: a female with two cubs-of-the-year and another with two year old cubs. All were in excellent condition, as were the other four adults. Novaya Zemlya, if indeed this is where the incident took place, is between the Barents and Kara Seas (see below):

Dubai builds first coal power plant despite pledging lowest carbon footprint in the world by 2050

by Independent, Oct 22, 2020

A new wonder is rising in the southern desert of Dubai against the backdrop of Persian Gulf beaches, but it’s not another skyscraper to grace the futuristic sheikhdom. Instead, it’s one of mankind’s oldest power sources gaining its own space on the oil-rich Arabian Peninsula — a coal-fired power plant

The construction of the $3.4 billion Hassyan plant in Dubai appears puzzling, as the United Arab Emirates hosts the headquarters of the International Renewable Energy Agency. It’s also building the peninsula’s first nuclear power plant and endlessly promotes its vast solar-power plant named after Dubai’s ruler. Dubai has also set the lofty goal of having the world’s lowest carbon footprint in the world by 2050 — something that would be impacted by burning coal.

The coal plant’s arrival comes as Gulf Arab nations remain among the world’s hungriest for energy and amid political concerns over the use of natural gas imported from abroad, concerns underscored by a yearslong dispute with gas-producer Qatar, which is boycotted by four Arab nations, including the UAE.

“Dubai was really saying we’re far too exposed on gas imports, those could be interrupted by all kinds of things, the cost is very high and so we have to do something else to diversify our fuel supply and bring down the total cost,” said Robin Mills, the CEO of Qamar Energy, a Dubai-based consulting company. “They got a very competitive offer on the coal plant … and so the decision was made.”

New Study: East Antarctica Was Up To 6°C Warmer Than Today During The Medieval Warm Period

by K. Richard, Oct 15, 2020 in NoTricksZone

As recently as 2000 to 1000 years ago, spanning the Roman to Medieval Warm Periods, East Antarctica was 5-6°C warmer than it is today. The consequent ice melt resulted in >60 meters higher water levels in East Antarctica’s lakes.

East Antarctica has been rapidly cooling in recent decades, with magnitudes reaching -0.7°C to -2.0°C per decade since the mid-1980s (Obryk et al., 2020).

…

A new study (Myers et al., 2020) reports that until about 15,000 years ago and throughout the Last Glacial Maximum, East Antarctica was 4-9°C colder than it is today.

Antarctica then abruptly warmed 15°C within centuries. From 12,000 to 6,000 years before present, East Antarctica was about 5°C warmer than it is today.

NORTHERN HEMISPHERE SNOW MASS ABOVE AVERAGE + GREENLAND ICE SHEET’S ASTONISHING GAINS CONTINUE

by Cap Allon, Oct 21, 2020 in Electroverse

Following on from one of its snowiest winters on record in 2019-20 comes the first 2020-21 data-points from the Finnish Meteorological Institute (FMI). What they clearly reveal is that the Northern Hemisphere is at it again, continuing the trend of growth observed in recent years.

Despite decades of doom-and-gloom prophecies and fear-mongering claptrap, the Northern Hemisphere continues to GAIN “snow mass” at a rate comfortably above the 1982-2012 average:

Climate experts fly more often than other scientists

by B. Webster, Oct 20, 2020 in TheTimes

Scientists who specialise in climate change fly more than other researchers, according to a study by Cardiff University that has prompted calls for them “to look in the mirror” before demanding that others cut emissions.

Climate scientists take about five flights a year on average for work while other researchers take four. Climate professors catch nine flights a year compared with eight for all professors.

De Telegraaf Misled By UN Disaster Report Researcher

by P. Homewood, Oct 20, 2020 in NotaLotofPeopleKnowThat

You will all recall the latest UN report, which claimed there had been a massive rise in “reported disasters” in the last two decades, compared to the previous two.

The Dutch newspaper, De Telegraaf, published an article in response complaining that the UN were not comparing like with like, because many smaller disasters were simply never recorded in the past. They also published this reply from Joris van Loenhout, researcher at the Belgian Centre  for  Research on the Epidemiology of Disasters  (CRED):

“From about 1960-1970 onward, the completeness of the data is much greater, and the share of missing disasters much smaller. We are constantly working to improve completeness, and this is also happening for previous years and decades. For this reason, statements made in 2004 and 2006 are now somewhat outdated, as the completeness of the database has since improved,”

 I have now had time to analyse CRED’s database, EM-DAT, and have the figures to show that Loenhout has not been telling the truth.

 

In their 2004 report, “Thirty Years of Natural Disasters”, CRED included this table of the number of natural disasters:

Creepy Climate Conversations

by Donna Laframboise, Oct 21, 2020 in BigPicturesNews

Tony Thomas has a disturbing piece over at Quandrant.org, concerning an Australian organization allegedly run by child activists. It’s now urging kids to initiate creepy conversations with adults as a means of spreading climate propaganda.

Matters may not develop as expected, though. Because any adult who was around for the global cooling scare, who was told acid rain would wipe out the worlds forests, and that the hole in the ozone layer would induce widespread skin cancer has, in fact, heard it all before.

It’s interesting that the SchoolStrike4Climate.com website can’t stay on topic. Its front page tells us Australia was stolen from First Nation communities, and that “there can be no climate justice without first nations justice.” If you click the large button labelled: Black Lives Matter Resources, you’re taken to a 7-page Google document that similarly declares: “There is no climate justice without racial justice…”

These statements, call to mind 17-year-old Greta Thunberg’s assertion that “We can not have climate justice without gender equity.”

Climate justice. First Nations justice. Racial justice. Gender equity. What does this collection of causes tell us? That these young people aren’t rebels at all. Nor are they independent thinkers.

Rather than being sincere and passionate about a single issue they themselves have carefully investigated, these youngsters are merely hopping aboard the bandwagon known as fashionable left wing politics.

If you truly believed your future was imperiled, wouldn’t you keep on topic? Wouldn’t your anxiety focus your attention? Wouldn’t you pursue a single, realistic, achievable goal?

Instead, these high school students are being encouraged to believe that, by skipping school, they’ll convince the rest of us to do their bidding – not just about the climate, but with respect to other complicated, longstanding social issues. Everything will be transformed. Fixed to their satisfaction. All at the same time, no less.

Only a naive young person could imagine this to be remotely possible.

New Climate Report: Islands Not Losing Land, People To Sea-Level Rise

by J. Taylor, Oct 19, 2020 in ClimateChangeDispatch

A new study posted at ClimateAtAGlance.com documents that most small islands are growing, not losing land to sea-level rise, and island nations are attracting growing populations rather than shedding climate refugees.

The new climate summary drives a stake into the heart of alarmist assertions that climate change and rising seas are threatening island nations and their populations.

Objective measurements show that islands and atolls are growing in size, not disappearing under rising seas.

Rising seas bring sand and sediment, which build up coastal shorelines and are more than keeping pace with rising waters.

Also, coral, as living organisms growing near sea level, build up their height along with the rising sea.

For example, climate activists often claim the island nation of Tuvalu is shrinking due to rising seas and spawning climate refugees.

However, a recent peer-reviewed study found eight out of Tuvalu’s nine coral atolls have grown in size during recent decades, and three-fourths of Tuvalu’s 101 reef islands have similarly grown in size.

Also, Tuvalu’s population is consistently growing, not declining, with 20% more people living on Tuvalu now than 30 years ago. Tuvalu’s population has doubled since 1970.

Additional peer-reviewed studies (see here, here, and here) confirm the same processes are allowing – and will continue to allow – other Pacific islands to keep up with rising seas.

For example, 30 years ago, the Canberra Times claimed all 1196 islands that comprise the Maldives could be completely underwater by now.

Not only are all 1196 islands still there, but the Maldives population has doubled during the past 20 years.

People are flocking to the Maldives islands, not fleeing them. The Maldives are absorbing political refugees, not spawning climate refugees.

Is Mauna Loa Really The Best Location To Measure ‘Global’ CO2 Levels?

by K. Richard, Oct 19, 2020 in NoTricksZone

Highly anomalous terrain (an active volcano), 40 years of cooling temperatures, and a CO2 record that dramatically contrasts with fluctuating values from forests and meadows reaching 600-900 ppm all beg the question: Is Mauna Loa’s CO2 record globally representative?

Mauna Loa is the Earth’s largest land volcano. It has erupted over 3 dozen times since 1843, making this terrestrial landscape extremely unusual relative to the rest of the globe’s terrain. (Forests, in contrast, cover over 30% of the Earth’s  land surface.)

Mauna Loa has been thought to be the world’s best location to monitor global CO2 levels since 1958.

While Mauna Loa CO2 levels show a rise of 338 ppm to 415 ppm since 1980, Mauna Loa temperatures (HCN) show a cooling trend during this same time period. The only warming period in the last 65 years occurred between about 1975 and 1985.

Image Source: oz4caster

Forest CO2 fluctuations

As mentioned above, forests are orders of magnitude more terrestrially representative than the highly anomalous site of the Earth’s largest volcano.

In forests or tree-covered areas, CO2 rises from around 300 ppm in the warmth of the afternoon (~3 p.m.) to over 600 ppm before sunrise (~4 a.m.), when it is cooler (Fennici, 1986, Hamacher et al., 1994). This massive fluctuation occurs daily and CO2 values average out to be far higher than the Mauna Loa record suggests.

Half the Reef destroyed but they won’t release the data

by JoNova, Oct 16, 2020

The future of the entire 350,000 km2 Great Barrier Reef hangs in the balance — as the coralapocalypse has wiped out 50% of the coral in just 25 years. Lordy! If only we’d built some off-shore wind farms on the reef to protect it! We could cover whole islands with solar panels? What are we thinking!

But as Peter Ridd points out, AIMS (The Australian Institute of Marine Science) surveys around 100 reefs every year — and for the last 35 years — and they find things are roughly the same. See the graph below.

Somehow Terry Hughes — and the Centre of Excellence for Integrated Coral Reef Studies — gets up to $4 million each year to report on the reef but won’t release the data behind the mass media campaign.

The ABC — which gets nearly $3 million dollars every single day — can’t even pick up the phone to interview AIMS or Peter Ridd and ask one hard question of Terry Hughes’ “Excellent” centre. (We all know why they had to put the word “excellence” in the title, it was the only way the word would ever be used to describe an activist group pretending to be scientists.)

And we all know that if anyone at James Cook University (JCU) has any doubts about the quality of the output from the “Excellent” centre they won’t be saying a word or they’ll get sacked like Peter Ridd did.

JCU — still supporting junk science and ignoring that other case of potential fraud?

Low Solar Activity Points To Colder Than Normal 2020/21 European Winter

by P. Gosselin, Oct 16, 2020 in NoTricksZone

SnowFan here reports on the latest winter forecasts for the 2020/21 Europe winter. History and statistics show Europe could be in for a frosty winter. 

Currently a significant La Nina is shaping up, and history shows that these events in the Pacific have an impact on Europe’s winters:

 

 

The NOAA reanalysis above shows the temperature deviations (left) and for precipitation (right) from the WMO average 1981-2010 during the six La Niña years of winter in Europe. Large parts of Europe have average temperatures and precipitation is distributed differently, with Germany being slightly drier overall than the WMO average. Is a 2020/21 winter in Germany under La Niña conditions shaping up to have average temperatures and slightly less humidity?

Strong winter-solar correlation

A more important factor determining winter in Europe may be solar activity. Data from the German DWD national weather service since 1954 show a remarkable higher frequency of cold winters in times of low solar activity, such as we are now in the midst of.

The Great Energy Non-Transition

by B. Everett, Oct 15, 2020 in CO2Coalition

One of the troubling characteristics of today’s civic discourse is the tendency to confuse predictions with reality.  Nowhere is this problem more severe than in the debate over climate and its associated issues.

The last hundred years have seen increasing emissions of carbon dioxide – a benign gas.  In reality, this slight increase in atmospheric CO2 concentrations (from 0.03% in the nineteenth century to 0.04% today) has brought nothing but beneficial effects, including increased crop yields and greater drought resistance.  Nonetheless, climate alarmists argue that rising temperatures are bringing catastrophic storms, flooding, disease, inundation, extinction and general misery.  Unlike the benefits of CO2 which are clear and measurable, climate catastrophe remains nothing more than a prediction generated by computer models which have never produced meaningful forecasts of climate impacts.

A frequent corollary of climate alarmism is that the world has undertaken a radical transformation of the global energy system away from fossil fuels toward zero-carbon, renewable energy.  A Google search of the term “energy transition” yields over 5 million hits, many accompanied by terms such as “unstoppable” and “irreversible”.  But is this transition actually taking place? Three arguments are generally offered – none of them valid.

First, “energy transition” supporters point to the high growth rates for renewable energy sources with wind increasing at over 20% annually since 2000 and solar at over 40% per year, compared to less than 2% for fossil fuels.  Sounds great, but the absolute numbers tell a different story.  In 2019, despite forty years and trillions of dollars of subsidies, wind energy contributes about 2% of total global energy use and solar just over 1%.  Fossil fuels accounted for 84%, down just two percentage points over the last 20 years.

Energy and Climate Policy—An Evaluation of Global Climate Change Expenditure 2011–2018

Concern for climate change is one of the drivers of new, transitional energy policies oriented towards economic growth and energy security, along with reduced greenhouse gas (GHG) emissions and preservation of biodiversity. Since 2010, the Climate Policy Initiative (CPI) has been publishing annual Global Landscape of Climate Finance reports. According to these reports, US$3660 billion has been spent on global climate change projects over the period 2011–2018. Fifty-five percent of this expenditure has gone to wind and solar energy. According to world energy reports, the contribution of wind and solar to world energy consumption has increased from 0.5% to 3% over this period. Meanwhile, coal, oil, and gas continue to supply 85% of the world’s energy consumption, with hydroelectricity and nuclear providing most of the remainder. With this in mind, we consider the potential engineering challenges and environmental and socioeconomic impacts of the main energy sources (old and new). We find that the literature raises many concerns about the engineering feasibility as well as environmental impacts of wind and solar. However, none of the current or proposed energy sources is a “panacea”. Rather, each technology has pros and cons, and policy-makers should be aware of the cons as well as the pros when making energy policy decisions. We urge policy-makers to identify which priorities are most important to them, and which priorities they are prepared to compromise on.

WHY IS NORTH AMERICA IMMUNE TO GLOBAL WARMING?

by Cap Allon, Oct 9, 2020 in Electroverse

I’m not trying to be facetious here, but I don’t know what other stance climate alarmists can take. Every data point –even those from warm-mongers NOAA– reveals that the North American continent is cooling.

Taking NOAA’s data as read, with its Urban Heat Island (UHI) bias, it still reveals a sharp cooling trend across the U.S. and Canada from 2015 through 2019. A trend that has continued into 2020 with the majority of regions suffering a late start to summer, and, now, an early beginning to winter.

North America is currently bracing for its sixth or seventh (I’ve genuinely lost count) Arctic blast of the season. By next Monday (Oct 19) an enormous mass of polar cold will have engulfed 90+% of the continent:

Claim: The deep sea is slowly warming

by American Geophysical Union, Oct 13, 2020 in WUWT

WASHINGTON–New research reveals temperatures in the deep sea fluctuate more than scientists previously thought and a warming trend is now detectable at the bottom of the ocean.

In a new study in AGU’s journal Geophysical Research Letters, researchers analyzed a decade of hourly temperature recordings from moorings anchored at four depths in the Atlantic Ocean’s Argentine Basin off the coast of Uruguay. The depths represent a range around the average ocean depth of 3,682 meters (12,080 feet), with the shallowest at 1,360 meters (4,460 feet) and the deepest at 4,757 meters (15,600 feet).

They found all sites exhibited a warming trend of 0.02 to 0.04 degrees Celsius per decade between 2009 and 2019 – a significant warming trend in the deep sea where temperature fluctuations are typically measured in thousandths of a degree. According to the study authors, this increase is consistent with warming trends in the shallow ocean associated with anthropogenic climate change, but more research is needed to understand what is driving rising temperatures in the deep ocean.

“In years past, everybody used to assume the deep ocean was quiescent. There was no motion. There were no changes,” said Chris Meinen, an oceanographer at the NOAA Atlantic Oceanographic and Meteorological Laboratory and lead author of the new study. “But each time we go look we find that the ocean is more complex than we thought.”The challenge of measuring the deep

Researchers today are monitoring the top 2,000 meters (6,560 feet) of the ocean more closely than ever before, in large part due to an international program called the Global Ocean Observing System. Devices called Argo floats that sink and rise in the upper ocean, bobbing along in ocean currents, provide a rich trove of continuous data on temperature and salinity.

The “Warmest September Ever” Is A Myth… Cooler Times Likely Ahead As NASA Foresees Strong La Nina…

by P. Gosselin, Oct 9, 2020 in NoTricksZone

Our friend “SnowFan” here looks at the claims that September 2020 was the warmest ever recorded. It turns out that other measurement advanced satellites don’t agree.

According to the much ballyhooed data, temperatures in Europe in September this year were on average 0.2 degrees Celsius higher than in the previous record September 2018. The service providing the data is part of the European earth observation program Copernicus.

But the satellite data from the UAH and RSS both agree that this is not really the case!

 

Above the global satellite data from UAH (left) and from RSS (right) in the tables clearly clearly show the monthly deviations from the WMO mean 1981-2010 (UAH) and from the climate mean 1979-1998 (RSS): September 2020 was not the warmest since satellite measurements began in 1979. At UAH, September 2019 was slightly warmer while at RSS even September 2017 was warmer.

LA NINA HAS ARRIVED: NEAR-TERM COOLING

by Cap Allon, Oct 11, 2020 in Electroverse

The following article is written by Bob Hoye of www.pivotaladvice.com.

Last week, the Global Warming policy Forum headlined “La Nina Is Here”. Why the headline? Because the warming El Nino is over and the change to the La Nina represents cooling. Like seasonal and actual climate change, it is a regular event. Which in physics means logical and predictable. And some cooling is showing up in various charts. Well, in those not altered by promoters of AGW.

Geologists solve puzzle that could predict valuable rare earth element deposits

by University of Exter, Oct. 11, 2020 in WUWT

Pioneering new research has helped geologists solve a long-standing puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits.

A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

The elements are among the most sought after, because they are an essential part of digital and clean energy manufacturing, including magnets in large wind turbines and electric cars motors.

For the new research, scientists conducted a series of experiments that showed sodium and potassium – rather than chlorine or fluorine as previously thought – were the key ingredients for making these rare earth elements soluble.

This is crucial as it determines whether they crystalise – making them fit for extraction – or stayed dissolved in fluids.

The experiments could therefore allow geologists to make better predictions about where the best concentrations of neodymium and dysprosium are likely to be found.

The results are published in the journal, Science Advances on Friday, October 9th 2020.

University of Exeter researchers, through the ‘SoS RARE’ project, have previously studied many natural examples of the roots of very unusual extinct carbonatite volcanoes, where the world’s best rare earth deposits occur, in order to try and identify potential deposits of the rare earth minerals.

Magically correcting Australia’s thermometers from 1,500 kilometers away

by JoNova, Oct 8, 2020

The Australian Bureau of Meteorology uses “surrounding” thermometers to adjust for odd shifts in data (caused by things like long grass, cracked screens, or new equipment, some of which is not listed in the site information). The Bureau fishes among many possible sites to find those that happen to match up or , err “correlate” during a particular five year period. Sometimes these are not the nearest site, but ones… further away. So the BOM will ignore the nearby stations, and use further ones to adjust the record.

These correlations, like quantum entanglements, are mysterious and fleeting. A station can be used once in the last hundred years to “correct” another, but for all the other years it doesn’t correlate well — which begs the question of why it had these special telediagnostic powers for a short while, but somehow lost them? Or why a thermometer 300km away might show more accurate trends than one 50km away.

One of the most extreme examples was when Cobar in NSW was used to adjust the records at Alice Springs –almost 1500km away (h/t Bill Johnston). That adjustment was 0.6°C down in 1932 (due to a site move, we’re told). This potentially matters to larger trends because Alice Springs is a long running remote station — the BOM itself says that Alice Springs alone contributes about 7-10 % of the national climate signal.[1] Curiously Cobar itself was adjusted in 1923 by a suite of ten stations including Bendigo Prison which is another 560 km farther south in a climate zone pretty close to Melbourne. In 1923 Cobar official temperatures were adjusted down by a significant 1.3 °C. No reason is given for this large shift — a shift larger than the entire (supposed) effect of CO2 in the last hundred years.

– All-time highest temperature: 112° F (Centreville on Sept. 6, 1925)

– All-time lowest temperature: -27° F (New Market 2 on Jan. 30, 1966)

ALASKA

– All-time highest temperature: 100° F (Fort Yukon on June 27, 1915)

– All-time lowest temperature: -80° F (Prospect Creek on Jan. 23, 1971)

ARIZONA

– All-time highest temperature: 128° F (Lake Havasu City on June 29, 1994)

– All-time lowest temperature: -40° F (Hawley Lake on Jan. 7, 1971)

ARKANSAS

All-time highest temperature: 120° F (Ozark on Aug.10, 1936)

– All-time lowest temperature: -29° F (Gravette on Feb.13, 1905)

CALIFORNIA

– All-time highest temperature: 134° F (Greenland Ranch on July 10, 1913)

WISCONSIN

– All-time highest temperature: 114° F (Wisconsin Dells on July 13, 1936)

– All-time lowest temperature: -55° F (Couderay 7 W on Feb. 4, 1996)

WYOMING

– All-time highest temperature: 115° F (Basin on Aug. 8, 1983)

– All-time lowest temperature: -66° F (Riverside Ranger Station, Yellowstone National Park) on Feb. 9, 1933)

More than 210 degrees Fahrenheit separates the highest and the lowest temperatures on record in the United States, and it isn’t a coincidence that the majority of these temperatures records –for both hot and cold– occur during solar minimums.

This is because low solar activity weakens the jet stream, reverting its usual tight ZONAL flow to more of a wavy MERIDIONAL one. This violent “buckling” effect FULLY explains how regions can experience pockets of anomalous heat while others, even relatively nearby, can be dealing with blobs of record cold: basically, in the NH, Arctic cold is dragged anomalously far south and Tropical warmth is pushed unusually far north (for more see the two links below)

Pic de la demande de pétrole : mythe ou réalité ?

by M. Cordiez, 9 Oct 2020 in ConnaissancedesEnergies

Et si on considérait le problème dans l’autre sens ?

Historiquement, le succès des compagnies pétrolières était jugé à leur capacité à renouveler, voire accroître, leurs réserves par des découvertes. Avec le temps et l’épuisement des ressources aisément accessibles, cet exercice est devenu de plus en plus complexe pour les majors privées (BP, Total, ENI…). L’essentiel des réserves conventionnelles sont aujourd’hui détenues par des compagnies nationales (Saudi Aramco, National Iranian Oil Company, Iraq National Oil Company…). Quant aux pétroles non conventionnels, il s’agit de ressources chères à exploiter, non rentables au cours actuel du baril, et sur lesquelles un positionnement reste de l’ordre du pari. Des sommes colossales ont été perdues par les fonds et entreprises qui ont investi dans le pétrole de roche mère aux États-Unis(6).

Les discours sur l’arrivée opportune d’un pic de la demande ne seraient-ils donc pas également un moyen pour les compagnies pétrolières d’offrir une narration positive face à leur incapacité à renouveler leurs réserves ? La conséquence de cette contrainte est alors présentée comme le fruit d’une stratégie : il n’est plus besoin de renouveler les réserves, vu que la demande va diminuer. Cette approche est en outre favorable en termes de communication car elle renvoie l’image de compagnies responsables vis-à-vis du climat, tout en portant un message optimiste : les émissions de gaz à effet de serre baisseront naturellement sans effort particulier, du fait d’une demande pétrolière qui diminuera d’elle-même.

Hors pandémie de Covid, nous devons garder à l’esprit que la consommation pétrolière – donc la demande – était croissante jusqu’en 2019 inclus. Elle a augmenté de 924 000 barils/jour entre 2018 et 2019, soit une augmentation de 0,9%(7). L’idée d’un pic de la demande est séduisante et rassurante, mais elle reste aujourd’hui une hypothèse prospective. D’ailleurs, plusieurs entreprises pétrolières telles que l’Américaine ConocoPhilips et la Russe Gazprom Neft prévoient une reprise de la croissance de la demande une fois la pandémie maîtrisée(8). Nous ne pouvons pas miser notre avenir sur le pari d’un déclin naturel de la demande de pétrole, qui serait poussé à temps vers la sortie par des solutions plus compétitives et déployables à large échelle.

Face aux incertitudes qui planent sur la pérennité de l’offre(9)(10) et à la nécessité impérieuse de réduire nos émissions de gaz à effet de serre pour atteindre la neutralité carbone, nous devons agir et tout mettre en œuvre pour assurer le déclin de la demande pétrolière. Répondre à cet enjeu nécessite d’aller au-delà de nos seules espérances quant au potentiel des technologies futures. Cela implique de faire évoluer notre rapport à l’énergie et à ses usages.

New book: Climate Change: The Facts 2020

by A. Watts, Oct 8, 2020 in WUWT

The Institute of Public Affairs today announced the release of a significant new book of research Climate Change: The Facts 2020 published by the Institute of Public Affairs and Australian Scholarly Publishing.

On 24 September 2019, the 17-year-old activist Greta Thunberg addressed the United Nations Climate Action Summit saying, “People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction.” A day earlier, however, the climate policy foundation Climate Intelligence (CLINTEL) sent the UN their World Climate Declaration, signed by 800 prominent scientists including Nobel Laureate Professor Ivar Giaever and Greenpeace co-founder Dr. Patrick Moore, stating that there is no climate emergency: “You’re tired of alarmism and failed predictions of climate models that can’t predict the past, let alone the future. You distrust the business leaders, politicians and scientists of the climate industrial complex – you just want The Facts.”

This book contains original research and new theories of climate and will arm you with these facts. Leading scientists are contributors, including former Senior Scientist for Climate Studies at NASA’s Marshall Space Center Dr. Roy Spencer, and lead author of the Intergovernmental Panel on Climate Change’s Third Assessment Report Professor Emeritus of Meteorology Richard Lindzen of Massachusetts Institute of Technology, and many more.

Climate Change: The Facts 2020 is the definitive guide to the latest international research and analysis on climate change science and policy.  Twenty experts in their field from across five countries have written original contributions on the key issues of scientific, political, and public debate about climate change.

​Some of the issues addressed in chapters in Climate Change: The Facts 2020 include:

  • the extent and variability of sea level change
  • the historical record of temperature and ice coverage in the Antarctic
  • the impact of climate change on polar bear populations
  • the manipulation of temperature data by the Bureau of Meteorology
  • whether the Australian bushfires 2019-20 were in fact ‘unprecedented’; and

the prevalence of ‘noble cause’ corruption in climate science.
