Scientists discover first super salty subglacial lakes in Canadian Arctic

by University of Alberta, April 11, 2018 in ScienceDaily


Super salty water beneath ice could serve as a terrestrial analogue for a habitat for life on other planets.

An analysis of radar data led scientists to an unexpected discovery of two lakes located beneath 550 to 750 meters of ice underneath the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic. They are thought to be the first isolated hypersaline subglacial lakes in the world.

Estimated 40 Percent of Scientists Doubt Manmade Global Warming

by National Association of Scholars, January 03, 2011


PRINCETON, NJ (January 3, 2011)—S. Fred Singer said in an interview with the National Association of Scholars (NAS) that “the number of skeptical qualified scientists has been growing steadily; I would guess it is about 40% now.”

Singer, a leading scientific skeptic of anthropocentric global warming (AGW), is an atmospheric physicist, and founder of the Science and Environmental Policy Project (SEPP), an organization that began challenging the published findings of the UN’s Intergovernmental Panel on Climate Change (IPCC) in the 1990s. SEPP established the Leipzig Declaration, a statement of dissent from the 1997 Kyoto Protocol that has been signed by over one hundred scientists and meteorologists.

Bahrain hits (black) gold with biggest shale discovery in world

by Catherine Philp, April 5, 2018 in TheTimes


Sheikh Mohammed bin Khalifa al-Khalifa said it was not yet known how much of the oil could be extracted. The scale of the find, however, is about to make it a big player in the global market, significantly boosting its economy and raising its profile in the region, where it plays a smaller fiddle to its giant neighbour, Saudi Arabia.

Science is Not Truth

by Donna Laframboise, April 4, 2018 in ClimateChangeDispatch


SPOTLIGHT: As the influence of religion has waned, we’ve placed science on a pedestal – mistaking it for an oracle of truth.

BIG PICTURE: Richard Harris has written a startling book about the state of medical research. The preface to Rigor Mortis: How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions includes a warning about scientific naivety:

Most of science is built on inference rather than direct observation…Science progresses by testing ideas indirectly, throwing out the ones that seem wrong…Gradually, scientists build stories that do a better job of approximating the truth.

Earth’s stable temperature past suggests other planets could also sustain life

by Anthony Watts,  April 3, 2018 in WUWT


Theories about the early days of our planet’s history vary wildly. Some studies have painted the picture of a snowball Earth, when much of its surface was frozen. Other theories have included periods that would be inhospitably hot for most current lifeforms to survive.

New research from the University of Washington suggests a milder youth for our planet. An analysis of temperature through early Earth’s history, published the week of April 2 in the Proceedings of the National Academy of Sciences, supports more moderate average temperatures throughout the billions of years when life slowly emerged on Earth.

Climate-Related Deaths Down by 98.9%; Last Year All-Time Low

by Bjorn Lomborg, April 2, 2018 in ClimateChangeDispatsch


CCD Editor’s Note: In 1920, CO2 levels were 303 PPM or 0.03%. Last year they were 406 PPM or 0.04%. Despite our global population quadrupling, climate deaths have actually gone down as CO2 levels have gone up. Lomborg explains why with the now-standard, often-by-rote “this does not mean that there is no global warming” caveat.

Lake Chad Might Be Shrinking, But It Has Nothing To Do With Climate Change

by P. Homewood, April 1, 2018 in NotaLotofPeopleKnowThat


Lake Chad – a source of water to millions of people in West Africa – has shrunk by nine-tenths due to climate change, population growth and irrigation. But can a scheme dating back to the 1980s save it?

“It’s a ridiculous plan and it will never happen.” That’s the reaction many people have to the idea of trying to fill up Lake Chad and restore it to its former ocean-like glory by diverting water from the Congo river system 2,400km (1,500 miles) away.

Terminal Pleistocene epoch human footprints from the Pacific coast of Canada

by D.C. McLaren et al., 2018 in PLOS.ONE


Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)

LES EVENEMENTS CLIMATIQUES EXTREMES DU PASSE (18)

by Jo Moreau, 25 mars 2018 in Belgotopia


Suite n° 18. (anno 1800-1849)

“Le contenu de la mémoire est fonction de la vitesse de l’oubli”

Désormais, chaque inondation quelque peu catastrophique, chaque tornade, chaque anomalie météorologique est rattachée au réchauffement climatique qui parait-il nous menace, mais dont en plus l’homme serait responsable !

Pourtant, la consultation de chroniques ou récits anciens est révélatrice de précédents tout aussi apocalyptiques, et relativise la notion même de “changements climatiques”, ainsi que la définition d’un “climat stable” qui n’a jamais existé mais qu’on voudrait instaurer à tout prix.

QUI CONNAIT LA TEMPERATURE GLOBALE REELLE DE LA PLANETE ?

by Jo Moreau, 19 mars, 2018 in Belgotopia


La question est posée dans un excellent article de Pierre Gosselin paru en juin 2017 sur son site incontournable (1).

Personnellement, et je ne suis évidemment pas le seul, je n’accorde aucun crédit aux annonces tonitruantes d’ “année la plus chaude”, de “record de température” dont sont si friands nos médias, et je conserve un scepticisme identique pour la détermination de la température globale moyenne de la planète. En effet, pour qui s’intéresse à l’actualité climatique, les contradictions et manipulations dans les relevés de température terrestre sont monnaie courante, sous prétexte bien souvent d’ajustements et de mise à niveau, que ce soit pour les relevés actuels ou “l’actualisation” de données anciennes…
L’avenir est connu, il suffit de modifier le passé“.

The Climate Dictionary

by Willis Eschenbach, March 16, 2018 in WUWT


Finally, we have the IPCC Likelihood Scale:

Virtually certain – “All my cool scientist friends agree”.

Very likely – “We really hope this is true”.

Likely – “Two climate models out of three agree”.

About as likely as not – “Nobody has a clue”.

Unlikely – “This outcome offends us”.

Very unlikely – “We really don’t want you going down that path”.

Exceptionally unlikely – “Stephen McIntyre said it first so it can’t possibly be true.”

How much snow accumulates in North America each year? More than scientists thought

by Ohio State University, March 13, 2018 in ScienceDaily


Scientists have revised an estimate of snow volume for the entire continent, and they’ve discovered that snow accumulation in a typical year is 50 percent higher than previously thought. Researchersplace the yearly estimate at about 1,200 cubic miles of snow. If spread evenly across the surface of the continent from Canada to Mexico, the snow would measure a little over 7.5 inches deep.

In the journal Geophysical Research Letters, researchers at The Ohio State University place the yearly estimate at about 1,200 cubic miles of snow accumulation. If spread evenly across the surface of the continent from Canada to Mexico, the snow would measure a little over 7.5 inches deep. If confined to Ohio, it would bury the state under 150 feet of snow.

Germany Is a Coal-Burning, Gas-Guzzling Climate Change Hypocrite

by P. Hockenos, November 13, 2017 in FPNews


Yet Germany’s image as selfless defender of the climate, which was once largely deserved, is now a transparent fiction. Germany has fallen badly behind on its pledges to sink its own greenhouse gas pollutants. In fact, Germany’s carbon emissions haven’t declined for nearly a decade and the German Environment Agency calculated that Germany emitted 906 million tons of CO2 in 2016 — the highest in Europe — compared to 902 million in 2015. And 2017’s interim numbers suggest emissions are going to tick up again this year.

A conversation with Patrick Moore

by P. Moore,  March 13, 2018 in A. Watts, WUWT


Patrick Moore is a Canadian activist, and former president of Greenpeace Canada. Since leaving Greenpeace, which he helped to found, Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement “abandoned science and logic in favor of emotion and sensationalism.” He has sharply and publicly differed with many policies of major environmental groups, including Greenpeace itself on other issues including forestry, biotechnology, aquaculture, and the use of chemicals for many applications.

Oceanic plastic trash conveys disease to coral reefs

by B. Friedlander, January 25, 2018 in CornellChronicle


“Plastics make ideal vessels for colonizing microscopic organisms that could trigger disease if they come into contact with corals,” Lamb said. “Plastic items – commonly made of polypropylene, such as bottle caps and toothbrushes – have been shown to become heavily inhabited by bacteria. This is associated with the globally devastating group of coral diseases known as white syndromes.”

When plastic debris meets coral, the authors say, the likelihood of disease increases from 4 to 89 percent – a 20-fold change. The scientists estimate that about 11.1 billion plastic items are entangled on reefs across the Asia-Pacific region, and that this will likely increase 40 percent over the next seven years.

LES CONFLITS D’ INTERET AU GIEC

by Jo Moreau, 9 mars 2018, in Belgotopia


Complémentairement à l’article de Donna Laframboise, il semblerait que les différents groupes de travail du GIEC n’aient pas la même définition d’un conflit d’intérêt. On peut identifier deux formes principales de conflit d’intérêt : soit l’utilisation d’une étude rédigée par un auteur ou coauteur du GIEC, ce qui revient à publier des études qu’on utilisera ensuite dans une auto-justification, (voir aussi à ce sujet un billet précédent : http://belgotopia.blogs.lalibre.be/archive/2013/01/03/methodes-interpellantes-au-sein-du-giec.html ), soit la présence en ses rangs d’un salarié de l’industrie ou d’un membre ou d’un proche d’une ONG militant dans le domaine idéologico-politique.

On se rappelle que des contributeurs du GIEC, salariés de l’industrie chimique, avaient été accusés par diverses sources de conflit d’intérêt en 2016, que dire alors de membres ou proches d’ONG militantes, qui semblent de plus en plus se substituer aux organes démocratiques dans la direction de nos sociétés…

Deep Bore Into Antarctica Finds Freezing Ice, Not Melting as Expected

by Douglas Fox, February 16, 2018 in NationalGeographic


Scientists have peered into one of the least-explored swaths of ocean on Earth, a vast region located off the coast of West Antarctica. It is locked beneath a crust of ice larger than Spain and more than 1,000 feet thick, making its waters perpetually dark—and extremely difficult for humans to access. Now, a team of researchers has bored a hole through the ice and sampled the ocean beneath it. Their work could shed light on a poorly understood, but ominous episode in Antarctica’s recent past… (…)

“Climate-Pope” Schellnhuber Stepping Down …Growing Impression He Had Become “More Activist Than Physicist”

by P. Gosselin, March 9, 2018 in NoTricksZone


Schellnhuber is often worshipped by the fringe-element climate alarmists as a sort of Climate Pope, whose every uttered word is to be regarded as infallible.  Now he may be paying the price for his entrenched, radical positions on climate change.

We now seriously need a Schellnhuber timeout. […] We do hope the new PIK leadership will correct the extreme direction the institute is currently on and rapidly puts an end to the flow of climate-alarmist press releases.“

Scientists Admit We Need Better Thermometers To Measure Climate Change

by M. Bastach, March 3, 2018 in DailyCaller


A group of prominent scientists are calling for a global network of advanced weather stations that don’t need to go through controversial data adjustments, and it’s vindication for global warming skeptics.

Seventeen climate scientists co-authored a research article published in the International Journal of Climatology calling for a global climate station network modeled after the United States Climate Reference Network (USCRN) to use as a baseline for data quality.
