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.

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.

Strong La Nina may be in the works

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.

A Geological Perspective of Polar Bears

by D. Middelton, Oct 11, 2020 in WUWT


Estimates have ranged from 70,000 to 5,000,000 years ago. The oldest confirmed polar bear fossil dates to 110,000 to 130,000 years ago… Meaning that polar bears survived the Eemian interglacial stage.

The peak warmth of the Eemian interglacial stage marks the boundary between the Late Pleistocene Tarantian Age and the Middle Pleistocene Ionian Age.

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.

LIST OF HISTORICAL TEMPERATURE EXTREMES BY U.S. STATE SHOWS NO SIGN OF GLOBAL WARMING

by Cap Allon, Oct 10, 2020 in Electroverse


Below I’ve compiled a list of the hottest and coldest temperatures ever recorded in each U.S. state, according to NOAA data. Surely, if catastrophic global warming was actually a thing then it would show up in the temperature records. Spoiler: it doesn’t, and a discussion on why follows the list.

ALABAMA

– 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.

UK ‘will take 700 years’ to reach low-carbon heating under current plans

by F. Harvey, Oct 8,2020 in TheGuardian


Ministers must come forward with stringent new plans for low-carbon heating, as targets to insulate homes and generate more power from offshore wind are inadequate and sales of gas boilers showed a record rise last year, energy experts warned.

At current rates, it will take 700 years for the UK to move to low-carbon heating, and at least 19,000 homes a week must be upgraded between now and 2050. There was a record rise last year of 1.8% in the number of new gas boilers installed, showing that the UK is going in the wrong direction.

Government plans will see only about 12,500 homes in total installed with low-carbon heat pumps, according to a report from the UK Energy Research Centre (UKERC).

“We must move away from this situation where the government is sitting on its hands,” said Robert Gross, director of UKERC and co-author of the report.

No new homes should be built with gas boilers, the experts said. The government’s pledge to build millions of new homes does not specify that they must be built with low-carbon heating.

The prime minister pledged this week that offshore wind would power and heat every home by 2030, with 40GW of turbines. But those plans are geared towards existing levels of electricity usage, UKERC experts pointed out. Demand for electricity is set to double as drivers switch to electric cars and as we cease to heat our homes with fossil fuels. According to one estimate, heating the UK’s homes alone would require 67GW of offshore wind power.

Corona-induced CO2 emission reductions are not yet detectable in the atmosphere

by Karlsruher Institut für Technology, Sep 21, 2020 in EurekAlert


Based on current data measured in the energy, industry, and mobility sectors, restrictions of social life during the corona pandemic can be predicted to lead to a reduction of worldwide carbon dioxide emissions by up to eight percent in 2020. According to the Intergovernmental Panel on Climate Change (IPCC), cumulative reductions of about this magnitude would be required every year to reach the goals of the Paris Agreement by 2030. Recent measurements by researchers of Karlsruhe Institute of Technology (KIT) revealed that concentration of carbon dioxide (CO2) in the atmosphere has not yet changed due to the estimated emission reductions. The results are reported in Remote Sensing (DOI: 10.3390/rs12152387).

A HISTORY OF CLIMATE FRAUD (I)

by Cap Allon, oct 5, 2020 in Electroverse


Much of the below analysis is courtesy of Kenneth Richard.

The combined Hadley Centre and Climatic Research Unit (HadCRUT) data set –which is featured in IPCC reports– underwent a revision from version 3 to version 4 in March of 2012, about a year before the next IPCC report was due.

At the time (early 2012), the HadCRUT3 was showing a slight global cooling trend between 1998 and 2012, visible in the graph below which uses HadCRUT3 and HadCRUT4 raw data. In conjunction with changing versions, the slight cooling trend had convenientlychanged to a slight warming trend:

 

As recently as 1990, it was widely accepted that the global temperature trend showed a “0.5°C rise between 1880 and 1950”, as reported by NASA (Hansen and Lebedeff, 1987). This rise (as well as the 0.6C rise between 1880 and 1940) can clearly be seen in the NASA GISS graph from 1987:

Tens Of Thousands Of Automotive Jobs On The Brink, Climate Policy Hammers Once Mighty German Auto Industry


by AR Göhring at EIKE, Oct 3, 2020 in NoTricksZone


Not only at Daimler, Volkswagen and others, but elsewhere the working people have to fear for their jobs after Brussels and Berlin have declared war on Germany’s most important industry. Now the automotive supply chain is also being hard hit.

Berlin, Brussels tighten the screws

The value-adding industry has already been badly shaken by the exaggerated, simply senseless corona measures of the Merkel IV government. Now the Brussels EU government (including former German minister Ursula von der Leyen) are tightening the screws even more as they love to ban internal combustion engines completely. The EU has just tightened the rules for limiting CO2 emissions. Not only the well-known car manufacturers are under pressure, but also their suppliers, hardly known by name, such as Mahle from Stuttgart.

Mass job losses

The globally producing parts manufacturer still has around 12,000 employees in Germany (72,000 globally). In the country, 2,000 workers are expected to lose their jobs, globally 7,600, and this despite a partial switch to e-car parts. It’s not enough, says a works council member, because there is no concept for the domestic combustion engine factories to convert over to electrical parts.

Michael Mann Appeals to, Then Ignores Scientific Consensus on 60 Minutes

by James Taylor, Oct 5, 2020 in WUWT


Prominent scientist and climate activist Michael Mann appealed to an asserted scientific consensus to chastise President Donald Trump on CBS’s 60 Minutes program last night. Ironically, Mann himself ignored clear scientific consensus in order to promote his own, out-of-the-mainstream climate change theories.

While interviewing Mann, CBS’s Scott Pelley said, “There have always been fires in the West. There have always been hurricanes in the East. How do we know that climate change is involved in this?” Pelley followed up with, “The president says about climate change, ‘Science doesn’t know.’”

Replied Mann, “The president doesn’t know, and he should know better. He should know that the world’s leading scientific organizations, our own U.S. National Academy of Sciences, and national academies of every major industrial nation, every scientific society in the United States that’s weighed in on the matter. This is a scientific consensus. There’s about as much scientific consensus about human-caused climate change as there is about gravity.”

Mann’s description of the conclusions of the “scientific consensus” however, is exactly the opposite of what scientific bodies report.

As documented in Climate at a Glance: Hurricanes, the United Nations Intergovernmental Panel on Climate Change (IPCC) expresses “low confidence” in any connection between climate change and changes in hurricane activity.

Similarly, as documented in Climate at a Glance: U.S. Wildfires, U.S. wildfires are much less frequent and severe than they were in the first half of the 20th century – 100 years of global warming ago. Moreover, the IPCC reports a decrease in drought conditions – which is the primary climate factor regarding wildfires – in the global region including the U.S. West. Moreover, the IPCC finds no evidence of an increase in drought globally, either.

Ultimately, data, evidence, and scientific facts are far more indicative of scientific truth than a real or imagined consensus of scientists. Yet, to the extent Michael Mann wishes to invoke consensus as a scientific argument, the clear consensus of scientists is that Mann is promoting extreme climate theories that have no basis in reality.

ARGENTINA HOLDS 8C TO 16C BELOW AVERAGE AS 2 FEET OF SNOW BURIES USHUAIA PROVINCE

by Cap Allon, Oct 4, 2020 in Electroverse


The out-of-season cold and snow currently blasting BOTH HEMISPHERES is intensifying: North America, western/northern Europe, central/eastern Asia, and practically ALL of Australia have now been joined by Argentina.

The South American nation of Argentina measures 2,175 miles long and lies between 21°S and 55°S. Despite its impressive latitude spanning length, the country has been completely engulfed by a powerful Antarctic blast.

Looking at the latest GFS run (shown below), Argentina is set to suffer temperature departures as much as 16C below the seasonal average on Sunday, Oct 4:

Restoring Scientific Debate on Climate

by Jim Steele, Oct 3, 2020 in WUWT


The political genius of Abraham Lincoln’s efforts to unify the country during America’s most divisive time has been attributed to assembling a “team of rivals”. Likewise, scientific research is published so rivals and supporters of a hypothesis can independently and critically examine it. The great benefits of a team of rivals is also the basis for convening red team/blue team debates.

In 2017, Dr Steve Koonin, a physicist who served as Obama’s Undersecretary for Science in the US Department of Energy, urged convening red-team blue-team debates for climate science in his article A ‘Red Team’ Exercise Would Strengthen Climate Science.  “The national-security community pioneered the “Red Team” methodology to test assumptions and analyses, identify risks, and reduce—or at least understand—uncertainties. The process is now considered a best practice in high-consequence situations”.

Unfortunately, the public climate science debate has been framed as “deniers” versus “alarmists”, or “honest saintly scientists” versus “corrupt perpetrators of a hoax”.  The media pushes exaggerated claims of a crisis while some scientists misleadingly shield their hypotheses claiming the “science is settled”.  But science is a process and never settled. However, all sides do agree carbon dioxide is a greenhouse gas and concentrations have increased. All sides agree the climate is changing. That science is indeed settled. But complex climate dynamics are not driven solely by CO2 and many unsettled questions remain.  Scientists still debate whether climate has a higher or lower sensitivity to rising CO2. Answering that question depends on the unsettled science regards competing contributions from natural variability and landscape changes. And because rising CO2 and warmth benefits photosynthesizing plants, scientists debate the beneficial contributions of rising CO2.

Climate models could not replicate recent warming when only natural climate change was considered. But models could simulate recent warming since 1970s after adding CO2. That was the only evidence that supported the notion that increasing CO2 caused observed warming. However, there’s a flaw in such reasoning. Models limited to just natural climate dynamics failed to explain recent changes simply because our understanding is still incomplete. For example the Pacific Decadal Oscillation, a major driver of natural climate change was only recently characterized in 1997, but has been shown to account for 100 years of changing climate along the coasts of the north eastern Pacific.

Ice discharge in the North Pacific set off series of climate events during last ice age

by Oregon State University, Oct 1, 2020 in Science Daily


Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth’s climate during the last ice age, new research published online today in Science reveals.

The discovery provides new insight into the impact rapidly melting ice flowing into the North Pacific may have on the climate across the planet, said Maureen Walczak, a paleoclimatologist in Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences and the study’s lead author.

“Understanding how the ocean has interacted with glacial ice in the past helps us predict what could happen next,” Walczak said.

The Cordilleran ice sheet once covered large portions of western North America from Alaska to Washington state and western Montana. Radiocarbon dating and analyses of the marine sediment record revealed that recurrent episodes of discharge from this ice sheet over the past 42,000 years were early events in a chain reaction of disturbances to the global climate. These disturbances triggered changes in deep ocean circulation and retreat of ice sheets in the North Atlantic.

Data Show Canadian Wildfires At Lowest Level In Decades

by A. Watts, Sep 29, 2020 in WUWT


Here’s something surprising from Paul Homewood, Not A Lot Of People Know That. While USA wildfires are running higher the last couple of years, according to Canada’s National Forestry Database, the number of forest fires in Canada has been at the lowest since 1990. Of course, Canada takes a management approach to forests compared to the USA’s “let it be or litigation” mess.

Source: http://nfdp.ccfm.org/en/data/fires.php

According to the Met Office, global warming is leading to record breaking fires in North America.

Canada, of course, is a large part of North America, so surely fires should be getting worse there too.

In fact wildfires this year are running at just 8% of the 10-year average:

 

Study: Global Warming Hiatus (aka “The Pause”) Was Real

by A. Watts, Sep 28, 2020 in WUWT


From the GWPF and the better late than never department: (the paper was published in late 2019 but seems pretty solid, using Oxygen18 isotope analysis) – Anthony

A new analysis of global air temperature by researchers from Tongji University in Shanghai has cast light on the much debated recent hiatus in global temperature.

Writing in the Journal of Earth Science the Chinese scientists say there was a rapid rise in global mean surface air temperature after the late 1970s but that this stalled and there was a relative stagnation and even slight cooling that lasted for about 15 years (1998–2012). They add that even though the slowdown was acknowledged by the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) and termed as a hiatus (IPCC, 2013) there was a debate in the scientific community about whether there was a hiatus in global warming or not.

The researchers believe that the debate about the global warming hiatus poses a substantial challenge to our understanding of the global climate response to anthropogenic greenhouse gas emissions and natural variability. They say that the disagreements about the recent global warming hiatus mainly arise from different sources, among which differences across observational SAT datasets may be a key contributor to the contradictory conclusions. So they use an alternative set of data.

They use the ratio of two oxygen isotopes in precipitation, oxygen 16 and 18, which is a proxy for the temperature of precipitation and surface temperature. They are particularly interested in what they term a “robust correlation” between precipitation oxygen ratios and surface temperature over mid- and high-latitude regions. Twelve stations were selected of which ten are located in Europe, and the remaining two in Antarctica and North America, respectively. Using the data they constructed a composite isotope index spanning 1970–2016 by combining twelve precipitation oxygen isotope records collected over mid and high-latitude continents. With it they evaluate the recent global warming hiatus.

OUT-OF-SEASON SNOW BLANKETS BOTH HEMISPHERES

by Cap Allon, Sep 29, 2020 in Electroverse


A merdional (wavy) jet stream flow is diverting brutal polar air to the mid-latitudes in BOTH hemispheres. Every continent on the planet is currently receiving out-of-season snow and anomalous cold, with a few of the worst hit nations being New Zealand, Australia, the United States, and France.

 

NEW ZEALAND

A spring weather bomb has battered New Zealand, closing roads, dumping snow on beaches and causing dozens of flight cancellations.

The NZ Met service has described the low-pressure system moving up the country from Antarctica as “very unusual in how widespread and severe the weather is” — they have called it a significant weather event.

The National Institute for Water and Atmospheric Research said parts of the South Island shivered through record-breaking lows of -20C (-4F) on Monday and Tuesday.

Flights were cancelled up and down the South Island due to heavy snow.

Disruptive flurries were even reported a sea-level: very unusual for spring:

11 SCIENTIFIC PREDICTIONS FOR THE UPCOMING GRAND SOLAR MINIMUM

by Cap Allon, Sep 18, 2020 in Electroverse


 There is ever-mounting evidence warning the next epoch will be one of sharp terrestrial cooling due to a relative flat-lining of solar output.

The exact time-frame and depth of this next chill of solar minimum is still anyone’s guess, and the parameters involved (i.e., galactic cosmic rays, geomagnetic activity, solar wind flux etc.) remain poorly understood. However, there are some great minds on the job, and below I’ve collated 11 best-guesses based on published scientific papers from respected researchers in the field. The list begins with eminent Russian astrophysicist K. Abdussamatov–though it is in no particular order.

BEACHED PILOT WHALES ARE A SIGN OF THE MAGNETIC POLE SHIFT AND WANING MAGNETOSPHERE

by Cap Allon, Sep 26, 2020 in Electroverse


Since 1850 Earth’s magnetic field has been weakening. At the turn of the millennium it then began reducing exponentially, at more than 10% per decade — this drop off is extreme and concerning, and here’s why.

Earth’s magnetic field protects us from space radiation. Our shields going down is very bad news for all life on our planet, and could possibly even lead to the next mass extinction.

“As the magnetic field weakens, the poles shift,” says David Mauriello of the ORP and MRN. For the past 100-or-so years, both north and south poles have been rapidly headed towards the equator (shown below), and their pace is increasing, warns Mauriello. The south pole is now off the Antarctic continent and making a beeline for Indonesia, and the north pole is shifting across the Arctic circle towards Siberia, it too headed for Indonesia–where the pair are likely to meet within the next few decades, perhaps around 2050.

This “meeting” will lead to one of two eventualities: 1) a full flip will take place (aka a “reversal” where the magnetic poles switch places), or 2) a “snap-back” will occur where the poles quickly return to their original starting points (aka an “excursion”).

A New Mass Extinction Event Has Been Discovered, And It Triggered The Rise of Dinosaurs

by M. Benton, Sep 25, 2020 in ScienceAlert


Huge volcanic eruptions 233 million years ago pumped carbon dioxide, methane, and water vapour into the atmosphere. This series of violent explosions, on what we now know as the west coast of Canada, led to massive global warming.

Our new research has revealed that this was a planet-changing mass extinction event that killed off many of the dominant tetrapods and heralded the dawn of the dinosaurs.

The best known mass extinction happened at the end of the Cretaceous period, 66 million years ago. This is when dinosaurs, pterosaurs, marine reptiles and ammonites all died out.

This event was caused primarily by the impact of a giant asteroid that blacked out the light of the sun and caused darkness and freezing, followed by other massive perturbations of the oceans and atmosphere.

Geologists and palaeontologists agree on a roster of five such events, of which the end-Cretaceous mass extinction was the last. So our new discovery of a previously unknown mass extinction might seem unexpected.

And yet this event, termed the Carnian Pluvial Episode (CPE), seems to have killed as many species as the giant asteroid did. Ecosystems on land and sea were profoundly changed, as the planet got warmer and drier.

On land, this triggered profound changes in plants and herbivores. In turn, with the decline of the dominant plant-eating tetrapods, such as rhynchosaurs and dicynodonts, the dinosaurs were given their chance.

In Parts Of Japan, Mean Maximum Temperatures May Be More Impacted By Remote Ocean Cycles Than By CO2

by P. Gosselin, Sep 26, 2020 in NoTricksZone


Today, according to government scientists, CO2 is supposed to be the dominant climate driver, overwhelming all the other power natural forces such as solar variability and oceanic cycles.

Yet when we compare (untampered) datasets, we often find surprising parallels and underlying correlations with these now ignored natural factors, which tell us CO2 isn’t what the activists want us to believe it is and that things are really much messier than the simplistic CO2-temperature correlation.

Today we look at a plot of the annual mean daily maximum temperature from Uwajima, Japan, together with the plot of the Atlantic Multidecadal Oscillation (AMO) going back almost 100 years.

Of course, nothing in a complex system like climate is going to show a perfect correlation, yet the above general fit is quite remarkable, which thus suggests regions are climatically interconnected in many yet to be understood ways. Such things aren’t accidental.

In summary: climate science is far from being understood, let alone settled. Anyone suggesting otherwise is likely just trying to sell you a bridge in Brooklyn – or they simply don’t know much about the subject and only parroting media sound bites.
