Réchauffement des océans, Tchernobyl, cancer et pesticides, liste bio, QI mondial… une semaine de fake news scientifiques

by J.P. Oury, 11 octobre 2019 in EuropeanScientist


Si le sujet « vérité et connaissance scientifique » est un pilier de la philosophie classique et de l’épistémologie contemporaine, il se pourrait bien que, dans une ère de post-vérité, ce thème soit progressivement remplacé par celui de la chasse aux « fausses informations ». Pour le dire autrement, ce qui compte, ce n’est plus la quête d’un sens métaphysique ou une recherche de cohérence logique, mais qu’un énoncé tienne le plus longtemps possible à la Une de l’actualité avant d’être remis en cause.

En affirmant ceci notre objectif n’est pas de donner un blanc seing au relativisme ou d’abandonner la méthode scientifique, bien au contraire. Il s’agit de réfléchir sur la possibilité de redonner à celle-ci  sa superbe ; d’autant plus qu’elle n’est plus simplement une affaire de scientifiques : les médias, les politiques, les ONG et l’opinion s’emparent immédiatement de la moindre expérience rendue publique et se trouvent engagés de manière quasi instantanée dans le processus de « vérification » qui passe d’abord souvent par l’acceptation. Ce qui montre la nécessité d’éduquer l’opinion pour lui apprendre à détecter les différentes typologies d’erreurs scientifiques. Voici donc une petite grille de lecture que nous avons établie en classant cinq grandes typologies d’informations scientifiques qui se sont révélées fausses…

It’s Time To Move Beyond The Toy Models that Guide Climate Policy

by Roger Pielke, October 7, 2019 in Forbes


Underlying discussion and debate of climate policies are computer models that bring together idealized representations of policies, economics and climate to estimate the impacts of future climate change and the benefits of mitigation. Such models, typically called integrated assessment models, are incredibly technical and complex. At the same time, they are also simplistic toys. Here I argue that while these models are valuable for exploring concepts and ideas, they have come to serve as a huge distraction when it comes to the development of actual policies that have a chance to accelerate rates of decarbonization in the real world.

Before proceeding, it is important to note that climate change poses real risks to our collective future, and aggressive mitigation and adaptation policies make good sense. However, the pace of progress, particularly on mitigation, has been frustratingly slow.

One way that integrated assessment models warp our discussion of climate policies is through the pervasive use of what are called “baseline scenarios.” These scenarios seek to represent where the world may be headed into the future in the absence of climate policies. Here is how the Intergovernmental Panel on Climate Change (IPCC) defines such scenarios, and their role in evaluating futures with climate policy (called “mitigation scenarios”):

Methodological debates are of course common in policy research. But in no area of policy that I have encountered over the past 30 years as a policy researcher have I come across a subject matter both as important as climate change and completely captured by one school of thought.

Scenario planning has an important role to play in the tool box of policy analysts. However, in the case of climate change, scenarios generated by integrated assessment models have overwhelmingly become the main tool of analysis in climate policy, to the exclusion of other valuable approaches. The result of this methodological myopia is that much of our collective intellectual attention has been spent on trying to figure out how to address climate change in models, and not in the real world.

WWF Apologizes Over Doctored Polar Bear Image In Climate Campaign

by Uutiset, October 8, 2019 in ClimateChangeDispatch


Environmental NGO WWF Finland has apologized for using a retouched photo of a polar bear and cub standing on a tiny ice floe, apparently adrift in an ocean.

However, the organization’s communications head, Anne Brax, also defended the use of the image as an advertising tool commonly used as shorthand for climate change and its impact on arctic regions, rather than as a news item.

The photo was used as part of an anti-climate change fundraising campaign aimed at students participating in Finland’s annual “taksvärkki” or “day’s work” program, where middle schoolers work for a day to collect money for worthy causes.

The image used in the campaign was originally shot by nature photographer Steven Kazlowski and depicts a polar bear and a cub. In the original photo, however, the polar bears are set against an icy landscape with no ocean in sight.

Alongside the manipulated image used in the WWF Finland campaign is the text “sulaa hulluutta kun ilmasto lämpenee”, which roughly translated means “pure madness as the climate warms”, with a play on the word “sulaa”, which also means “to melt” in Finnish.

WWF Finland: “We Made A Mistake”

A Democratic professor explains what his party gets wrong about climate

by Caleb Rossiter, July 18, 2019 in WashingtonExaminer


As the Republican-called witness at a recent hearing, I was denounced by the Democrats for denying a fossil-fueled “climate crisis” that, as their witnesses testified, results in violence against women, asthma and obesity in children, and deadly storms. But few actually questioned me. After all, “the debate is over.”

So instead, the latest belle of my party’s ball, Rep. Alexandria Ocasio-Cortez, left the dais to urge protestors outside to drown me out. She’d previously written Google and Facebook, asking them to block me and the CO2 Coalition of 50 unalarmed scientists I direct from speaking at conferences they sponsor.

At the hearing, I presented data from the United Nations contradicting the accepted wisdom that extreme weather is destroying the planet and is traceable directly to a man-made climate crisis. There are no such trends in rates of sea-level rise, hurricanes, floods, or droughts. One Democrat who stuck around to actually question me simply asserted that our coalition is funded by energy companies. I wish! Another wanted to know, “Do you believe in climate change or not?” When I asked him to define it, he cut me off with: “That answers it all…That gives us a hint where you’re coming from.”

Indeed it does. Where I’m coming from is academia, where defining the scientific terms we discuss is elemental.

The whole affair shows just how much has changed. A decade ago I’d been the one pummeling a Republican-called witness, a little-known pollster named Kellyanne Conway, in my role as counsel to a Democratic committee chairman. And the last time I’d been a witness, as director of a foreign policy group in 1994, I’d been called in by Democrats who were backing our “no arms to dictators” bill. But now I am a heretic for using scientific facts to dispute exaggerated talking points.

Solar activity drives CO2 levels

by R. Mac, August 10, 2014  in TheHockeySchtick


Hypothesis: Increasing accumulated solar activity [sunspot time-integral] since the Maunder Minimum 1645-1715 AD has warmed the oceans and land, warming of the oceans has increased ocean outgassing of CO2 [Henry’s Law] and has been the primary cause of increased atmospheric CO2 levels. Ocean temperatures driven by solar activity control atmospheric CO2 levels on short, intermediate, and long-term timescales.

Also note if increased solar activity warms the oceans, the solubility of CO2 in the oceans decreases due to Henry’s Law, thus preventing “acidification” of the oceans. If the oceans are warming due to any cause, Henry’s Law says solubility of CO2 decreases and outgassing increases, preventing “acidification” from man-made and natural sources of CO2. Warnings about ocean acidification are misleading and overblown:

Solar-Climate Theory Sheds New Light On History Of Chinese Civilization

by S. Chen, Sep; 24, 2019 in ClimateChangeDispatch


Scientists say they have found evidence beneath a lake in northeastern China that ties climate change and 500-year sun cycles to ups and downs in the 8,000 years of Chinese civilization.

According to the study by a team at the Institute of Geology and Geophysics in Beijing published in the science journal Nature Communications this month, whenever the climate warmed, Chinese civilization prospered and when it cooled, it declined.

While historians have used various social and economic factors to explain changes over the millennia, Dr. Xu Deke, lead author of the paper, and his colleagues said that while people played their part, their study indicated that cycles in solar activity influenced human activity.

“We just point out there is a natural constraint on human efforts,” Xu said.

Previous research linking Chinese history to climate relied on written records, but ancient texts contained only subjective descriptions of the weather and social development. The records also go back only so far – writing in China was not invented until 3,600 years ago.

For this latest study, the team and its leader, Chinese Academy of Sciences professor Lu Houyuan, took plant and lake bed sediment samples to track climate change over the centuries and compared them with written records.

 

Emmanuel Le Roy Ladurie A (re)lire absolument…

by Alain Préat,  3 octobre 2019 inScienceClimatEnergie


S’il est un livre, et un des premiers, à s’être penché de manière aussi détaillée sur l’évolution (récente) du climat, c’est celui d’Emmanuel Le Roy Ladurie ‘Histoire du climat depuis l’an mil’, publié en 1967.

Rappelons cependant le livre précurseur de Joseph-Jean-Nicolas Fuster publié en 1845 et récemment analysé ici même à SCE (et toujours disponible, voir ici).

 

1/ Introduction

A lire ou relire ce livre de 366 pages (Figure 1), on ne peut qu’être stupéfié par l’analyse rigoureuse qui met en évidence la variabilité naturelle du climat aux échelles pluriséculaire et décennale, qui décortique et privilégie  avec finesse le caractère local du climat par rapport à un climat global et fournit à partir d’indicateurs fiables des fourchettes de températures pour les variations climatiques observées à l’échelle pluriséculaire.

 Figure 1. Histoire du climat depuis l’an mil, Flammarion, publié en 1967

Avant d’aborder ce sujet en détail, il semble qu’aucun modèle sorti des ‘computers’ (GIEC) n’ait été jusqu’à présent capable de rendre compte des évolutions rapportées dans le livre d’ Emmanuel Le Roy Ladurie, ces modèles se prétendent ‘globaux’, contrairement à la conclusion du livre en question qui insiste particulièrement sur le caractère local des climats. Enfin il s’agit d’un livre de 366 pages bien illustré (photographies, cartes et graphiques) dans lequel il n’est pas mentionné une seule fois ‘le poison’ des temps modernes, à savoir le CO2. L’auteur, en 1967 (faut-il le rappeler …), propose ou explore quand  même des pistes pour rendre compte de la succession d’épisodes ‘froids’ et ‘chauds’, tout au long de ces 1000 années d’histoire, qui en fait  débutent il y a 3500 ans (mais pour ces temps historiques plus reculés, les données fiables sont moins nombreuses).

Trois solutions (et demie) pour le climat

by Prof. Samuel Furfari, 3 octobre 2019 in L’Echo


“Après avoir travaillé pendant plus de 40 ans dans le domaine, mon expérience me pousse à plaider pour une analyse factuelle et objective de la situation, même si elle peut paraître iconoclaste dans le climat actuel…’

Les feux des projecteurs de l’Assemblée générale de l’ONU s’étant éteints, il est temps de voir plus sereinement la situation en matière de politique climatique — et donc énergétique – qui menace dangereusement notre démocratie. Après avoir travaillé pendant plus de 40 ans dans le domaine, mon expérience me pousse à plaider pour une analyse factuelle et objective de la situation, même si elle peut paraître iconoclaste dans le climat actuel.

Malgré l’opinion générale, et de certains scientifiques, la science du climat est très jeune. Affirmer que “tout est connu et qu’il n’y a plus qu’à agir” est donc prématuré. Le rapport du GIEC est rempli de conditionnels. Pas de certitudes, mais des hypothèses loin d’être irrécusables, puisque le système climatique possède “une signature chaotique“.

Lorsque durant la vague de chaleur de cet été, le climatologue français Jean Jouzel annonce que la température augmentera de “trois ou quatre” degrés, il omet d’ajouter que le GIEC assortit cette hypothèse d’une probabilité de 1% et que c’est pour un maximum de 3°C et non de 4°C ou de 7°C comme on l’entend parfois.

‘There is no climate emergency,’ hundreds of scientists, engineers tell U.N.

by P. Homewood, October 2, 2019 in NotaLotofPeopleKnowThat


Lost amid the coverage of Swedish teen activist Greta Thunberg at last week’s U.N. Global Climate Summit were the 500 international scientists, engineers and other stakeholders sounding a very different message: “There is no climate emergency.”

The European Climate Declaration, spearheaded by the Amsterdam-based Climate Intelligence Foundation [CLINTEL], described the leading climate models as “unfit” and urged UN Secretary-General Antonio Guterres to pursue a climate policy based on “sound science.”

“Current climate policies pointlessly and grievously undermine the economic system, putting lives at risk in countries denied access to affordable, reliable electrical energy,” said the Sept. 23 letter signed by professionals from 23 countries.

Most of the signers hailed from Europe, but there were also scientists from the United States, Canada, Australia, New Zealand and South America.

“We urge you to follow a climate policy based on sound science, realistic economics and genuine concern for those harmed by costly but unnecessary attempts at mitigation,” the letter said.

Greta’s Soros Connections

by P. Homewood, 28 Sep. 2019 in NotaLotofPeopleKnowThat


Andrew Bolt is not afraid to tell the truth about our Greta. It is a pity that the media here have not got the courage to do the same…

 

16-year-old climate change activist Greta Thunberg has quickly risen to become one of the world’s most prominent political leaders, inspiring a mass movement of millions seemingly out of thin air to combat the problem of global warming.

 

However, the young girl’s sudden ascent to prominence is not happening by chance. She has deep connections to the globalist elite and activist parents who are supporters of the far-left domestic terrorist group ANTIFA.

 

Thunberg’s frequent handler is Luisa-Marie Neubauer, an operative from the ONE Movement. Neubauer can be seen behind Thunberg at many of her public events.

 

UK Climate Trends: Plus Ça Change: Climate hysteria is unjustified

by P. Homewood, September 27, 2019 in GWPF


London, 27 September: The UK’s key climate indicators have barely changed for 20 years. That’s according to a new paper from the Global Warming Policy Foundation, which rebuts claims that the weather is getting worse.
According to author Paul Homewood, the Met Office’s Central England Temperature Record shows that temperatures have barely changed in 20 years and that there has been no increase in extremely hot days either:
“The summer of 2018 had just one day over 30 degrees, while 1976 had six. The Met Office’s data show that hot days are just not becoming more common.”
And there seems to be little to worry about on bad weather front either. There has been a gentle decline in storminess, and in most of the UK, there has been no change in either average rainfall or rainfall extremes:
“Only in Scotland has there been a noticeable increase”, says Homewood. “Climate hysteria is entirely overdone.”

German Climatologist Werner Kirstein Unloads: “IPCC Is To Deceive People”…Calls Michael Mann’s Chart “A Fake”

by P. Gosselin, Sep.17, 2019  in NoTricksZone


German climate scientist Professor Werner Kirstein was interviewed by alternative media outlet NuoViso,  and since the video was released early this month on Youtube, it has been viewed over 130,000, times.

Politics commissioning reports for money

In the interview Professor Kirstein tells moderator Robert Stein that CO2 emissions have no effect on the climate and that “politicians commission climate scientists to produce expert reports for money.”

“Public is being deceived”

Prof. Kirstein talks about the “conscious deception” of the public and how all research projects and publications by “climate scientists” only have the goal of confirming “man-made climate change” and that different scientific views are not welcome.

According to Kirstein, the public is being deceived with the false information and that the aim of politics is to find a way to collect further taxes and to collect levies.

“We currently see this with the climate tax, which is to be introduced soon,” Kirstein says.

Climate Hysteria: Rising Number Of Children Treated For ‘Eco-Anxiety’

by P. Homewood, Sep. 16, 2019 in NotaLotofPeopleKnowThat


Protests by groups such as Extinction Rebellion, the recent fires in the Amazon and apocalyptic warnings by the teenage activist Greta Thunberg have prompted a “tsunami” of young people seeking help.

A group of psychologists working with the University of Bath says it is receiving a growing volume of enquiries from teachers, doctors and therapists unable to cope.

The Climate Psychology Alliance (CPA) told The Daily Telegraph some children complaining of eco-anxiety have even been given psychiatric drugs.

Important news from the world’s top meteorologist

by Larry Kummer, Editor, Sep.14, 2019 in WUWT


Summary: After years of tacit cooperation with climate activists, the first major climate agency may have begun to turn against their misuse of climate science. If so, this would be a big event in the climate debate. As seen in this interview with the head of the WMO. He has much to say that we need to hear.

Scientists are turning against climate activists and their scare tactics.

 

Excerpts from “Climate change is not yet out of control,
but the debate is

Greta, Germany & Green Energy

by J. Curry, Sep. 10, 2019 in BigPictureNews


Anyone who still thinks green/renewable energy is the answer is invited to click over to a web page that monitors Germany’s celebrated Energy Transition (English translation here). The most recent six-month update has just been published. Despite a multi-billion-euro price tag, Germany’s attempts to ditch fossil fuels isn’t going well. At all.

Only six of the transition’s 14 goals (43%) appear achievable by 2020. Here are the two absolutely critical data points:

#1 – Germany’s CO2 emissions reduction targets won’t be met.

#2 – Its previously robust electricity grid is now vulnerable and insecure.

The story of Germany’s energy transition boils down to this: Something that used to work well has been deliberately broken, undermined, degraded, and crippled. A ton of money has been spent. To make things worse.

Over at Forbes, Michael Shellenberger discusses how this latest report card is being covered in the German press. In his words:
