German Portrait Of The Thunberg-Ernman Family: Acutely Dysfunctional, “An Infinitely Sad Family History”

by U. Stockman, October 26, 2019 in NoTricksZone

At the German libertarian site achgut.com here, guest writer Ulrike Stockmannwrites a portrait of climate activist Greta Thunberg’s family. The title: “The Thunberg-Ernmans: An infinitely sad family history“.

 

Stockmann portrait is based on the published book by Greta Thunberg’s mother, Malena Ernman: “Scenes from the Heart”, which describes Greta’s past life and her path to becoming an environmental activist.

Family a drama and tragedy

Having read the book, Stockmann writes that “nothing surprises any more and that Greta being climate prophet is merely the tip of the iceberg of a family drama.”

What follows are excerpts of Stockmann’s portrait of the Ernman-Thunberg family:

Malena Ernman is a successful opera singer. Her husband Svante Thunberg is an actor. […] By the time Greta enters the fifth grade, suddenly she is no longer feeling well at all. She refuses to eat, cries all day long and is depressed. […]

Greta’s hunger strike becomes life-threatening: she eats almost nothing for two months. The parents take her to the hospital and the Centre for Eating Disorders. [..] In addition, Asperger’s syndrome, highly functional autism and OCD (obsessive-compulsive disorder) are diagnosed.

One day at school Greta sees a film about the pollution of the oceans showing a huge island of plastic waste and bursts into tears. Overall Greta is unhappy at school. […]  She doesn’t feel well at school. Everything becomes too much for her.”

Stockmann sees parental neglect, quoting Ernman in the book

Does the Climate System Have a Preferred Average State? Chaos and the Forcing-Feedback Paradigm

by Roy Spencer, October 25, 2019 in GlobalWarming

The UN IPCC scientists who write the reports which guide international energy policy on fossil fuel use operate under the assumption that the climate system has a preferred, natural and constant average state which is only deviated from through the meddling of humans. They construct their climate models so that the models do not produce any warming or cooling unless they are forced to through increasing anthropogenic greenhouse gases, aerosols, or volcanic eruptions.

This imposed behavior of their “control runs” is admittedly necessary because various physical processes in the models are not known well enough from observations and first principles, and so the models must be tinkered with until they produce what might be considered to be the “null hypothesis” behavior, which in their worldview means no long-term warming or cooling.

What I’d like to discuss here is NOT whether there are other ‘external’ forcing agents of climate change, such as the sun. That is a valuable discussion, but not what I’m going to address. I’d like to address the question of whether there really is an average state that the climate system is constantly re-adjusting itself toward, even if it is constantly nudged in different directions by the sun.

La science classique s’arrête où commence le chaos…

Prof. Igr. H. Masson, 25 octobre 2019 in ScienceClimatEnergie

1. Un nouveau paradigme : les systèmes chaotiques

« Depuis les premiers balbutiements de la Physique, le désordre apparent qui règne dans l’atmosphère, dans la mer turbulente, dans les fluctuations de populations biologiques, les oscillations du cœur et du cerveau ont été longtemps ignorées ».

 « Il a fallu attendre le début des années soixante-dix, pour que quelques scientifiques américains commencent à déchiffrer le désordre, il s’agissait surtout de mathématiciens, médecins, biologistes, physiciens, chimistes cherchant tous des connections entre diverses irrégularités observées. Le syndrome de la mort subite fut expliqué, les proliférations puis disparitions d’insectes furent comprises et modélisées, et de nouvelles méthodes d’analyse de cours boursiers virent le jour, après que les traders aient dû se rendre à l’évidence que les méthodes statistiques conventionnelles n’étaient pas adaptées. Ces découvertes furent ensuite transposées à l’étude du monde naturel : la forme des nuages, les trajectoires de la foudre, la constitution de galaxies. La science du chaos (« dynamical systems » pour les anglo-saxons) était née et allait connaître un développement considérable au fil des années ».

Who Are the “Experts” on Climate Change?

by John Droz, Jr October 22, 2019 in WUWT

We live in complicated times, immersed in a society of incessant, loud, conflicting voices. Nowhere is this more true than in the discussion of the impact of carbon dioxide on the planet, oceans, better known as “climate change.” When interested citizens try to get to the bottom of such a highly complex issue, the standard, and proper, rejoinder is: “Listen to the Experts.”

Although that sounds like common sense, such advice is not as simple as it’s made out to be. For millennia, it was safe to assume that mainstream scientists (as a matter of principle) faithfully adhered to high scientific standards (see below). In our lifetime that has dramatically (and disappointingly) changed.

Today there is an ever-increasing number of scientists driven by political agendas, peer pressure, job security, etc. rather than scientific mores. This change has extraordinarysocietal implications — and none of them are beneficial.

…

…

Real Experts on a science-related subject have six distinguishing characteristics, which are really no more than the traditional scientific standards:

1 – They have a high degree of competence in the topic at hand.

[For example, out of 1000 people, they would know more than 999.]

2 – They have a comprehensive understanding of the topic.

[They are not one of the blind people examining just a part of the elephant.]

3 – They are objective in their conclusions and recommendations.

[They are not influenced by economic incentives, or undeclared political agendas.]

4 – They are genuinely open-minded regarding their positions.

[They encourage other parties to critique their analyses and conclusions.]

5 – Their research and data are transparent.

[No pertinent information is hidden behind such claims as “work product.”]

6 – Their research and data are based on empirical evidence.

[Real world data always takes priority over computer-generated information.]

Antarctic ice cliffs may not contribute to sea-level rise as much as predicted

by Massachusetts Institute of Technology, October 21, 2019 in ScicnceDaily

Researchers report that in order for a 90-meter ice cliff to collapse entirely, the ice shelves supporting the cliff would have to break apart extremely quickly, within a matter of hours — a rate of ice loss that has not been observed in the modern record.

…

…

A realistic picture

The results suggest that the Earth’s tallest ice cliffs are unlikely to collapse catastrophically and trigger a runaway ice sheet retreat. That’s because the fastest rate at which ice shelves are disappearing, at least as documented in the modern record, is on the order of weeks, not hours, as scientists observed in 2002, when they captured satellite imagery of the collapse of the Larsen B ice shelf — a chunk of ice as large as Rhode Island that broke away from Antarctica, shattering into thousands of icebergs over the span of two weeks.

“When Larsen B collapsed, that was quite an extreme event that occurred over two weeks, and that is a tiny ice shelf compared to the ones that we would be particularly worried about,” Clerc says. “So our work shows that cliff failure is probably not the mechanism by which we would get a lot of sea level rise in the near future.”

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.

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.

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”

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.

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:

THICK ARCTIC ICE STOPS YET ANOTHER SHIP OF CLIMATE CHANGE DOCUMENTARY FILMMAKERS

The MS MALMO is the latest in a long list of ships to have gotten stuck in surprisingly thick Arctic sea ice this year.

The Swedish vessel, built in 1943 and refurbished in 2014, was on an “Arctic tour” with the noble mission of ferrying a team of Climate Change documentary filmmakers to the front line. The teams intention was to capture some of the catastrophic ice melt being reported by the worlds media — ice melt which it would appear still refuses to manifest despite decades of furious willing from the UN & IPCC.

La forêt amazonienne n’est pas le poumon de la planète

by SCE-INFO, 30 août 2019 in ScienceClimatEnergie

La forêt amazonienne fait beaucoup parler d’elle en ce moment. Selon le journal Le Monde mais également selon de nombreux autres médias, la forêt amazonienne est ravagée par des incendies d’une ampleur inédite, et ce depuis plusieurs semaines. Sans nier les feux ni l’importance de cette forêt au niveau de sa biodiversité, nous tenons à dénoncer quelques contre-vérités qui ont circulé.

1/ La forêt amazonienne n’est pas le poumon de la planète

Scientifiquement, l’expression “poumon de la planète” pour désigner l’Amazonie est fausse et prétendre que l’Amazonie produit 20% de notre oxygène — une assertion du Président français Macron lors du récent sommet du G7 — est fausse. Tout d’abord un poumon ne produit pas d’oxygène mais en consomme… Mais passons ce détail. Ce qu’il faut retenir est ceci : le bilan entre photosynthèse et respiration pour cet écosystème est nul du point de vue de l’oxygène [1] . La forêt amazonienne ne produit donc quasi pas d’oxygène, tout comme les océans, lorsque l’on considère le bilan net (photosynthèse + respiration). Tout ceci est même rappelé sur page Wikipedia consacrée à la forêt amazonienne, ou encore sur le site web du National Geographic.

Pour ceux qui ont du mal à lire en anglais, vous pouvez également lire le site français du Huffington Post, cette page de Planet Terre écrite en juin 2000, ou cet article écrit dans Le Parisien.

Pour ceux qui se posent la question de l’origine de l’oxygène que nous respirons (21% dans l’atmosphère actuelle), voici la réponse : nous respirons essentiellement un O2 libéré par des végétaux anciens (par exemple datant du Carbonifère) devenus matière organique fossile (ce carbone n’est pas dégradé par les bactéries des sols et sédiments et donc ne consomme pas d’oxygène atmosphérique). La page de Planet Terre citée précédemment explique parfaitement ce phénomène.

Michael Mann Refuses to Produce Data, Loses Case

by P. Homewood, August 26, 2019 in NotaLotofPeopleKnowThat

Some years ago, Dr. Tim Ball wrote that climate scientist Michael Mann “belongs in the state pen, not Penn State.” At issue was Mann’s famous “hockey stick” graph that purported to show a sudden and unprecedented 20th century warming trend. The hockey stick featured prominently in the IPCC’s Third Assessment Report (2001), but has since been shown to be wrong. The question, in my view, is whether it was an innocent mistake or deliberate fraud on Mann’s part. (Mann, I believe, continues to assert the accuracy of his debunked graph.) Mann sued Ball for libel in 2011. Principia Scientific now reports that the court in British Columbia has dismissed Mann’s lawsuit with prejudice, and assessed costs against him.

What happened was that Dr. Ball asserted a truth defense. He argued that the hockey stick was a deliberate fraud, something that could be proved if one had access to the data and calculations, in particular the R2 regression analysis, underlying it. Mann refused to produce these documents. He was ordered to produce them by the court and given a deadline. He still refused to produce them, so the court dismissed his case.

Amazonie : fake news, désinformation, manipulation !

by Jo Moreau, 26 août 2019 in Contrepoints

L’ avalanche d’articles, de photos et d’avis de personnalités de tous horizons sur les incendies qui ravagent l’Amazonie constitue une illustration parfaite du sale boulot de manipulation de l’opinion publique exercée par les médias, et porteur de l’amalgame trompeur diffusé jour après jour entre protection de l’environnement et réchauffement climatique.

La première chose qui a attiré mon attention est le rapport fait entre le nombre d’incendies constatés en 2019, avec la situation en… 2018. Il est à peine croyable qu’une comparaison aussi peu significative sur le plan statistique et trompeuse sur le plan historique ait été diffusée sans aucune réserve par tous les médias mondiaux, mais serve de surcroît les intérêts d’hommes et de femmes politiques, à commencer par le leader auto-proclamé de l’Union Européenne et porte-drapeau mondial de l’écologisme, j’ai nommé le président Macron.

« Notre maison brûle. Littéralement. L’Amazonie, le poumon de notre planète qui produit 20 % de notre oxygène, est en feu. C’est une crise internationale. Membres du G7, rendez-vous dans deux jours pour parler de cette urgence. »

Alors, soit le président Macron est mal informé, soit il suit aveuglément les avis très orientés d’ONG n’ayant aucune légitimité scientifique ou démocratique. Le problème est que la majorité de ceux qui nous gouvernent a une démarche identique.

Mais reprenons les choses dans l’ordre.

FAKE NEWS

Je place sous ce titre l’emploi par les médias ou sur les réseaux sociaux de photos parfois anciennes, non pas « fausses », mais tout à fait étrangères avec la situation actuelle en Amazonie.

Il s’agit d’une tactique souvent employée, destinée à émouvoir le public et l’orienter dans le sens voulu. Le choix des photos qui illustrent un article a une grande importance. Ainsi, les photos de dirigeants politiquement incorrects montrent souvent des visages grimaçants ou dans des poses peu avantageuses, tandis que les dirigeants idéologiquement corrects (aux yeux des médias) nous sont montrés souriants et sympathiques.

Mais l’emploi massif de ces photos « détournées » était tellement flagrant qu’après les avoir abondamment publiées, l’ensemble de la presse émit dans un deuxième temps des réserves prudentes quant à leur origine, ce qui lui permit accessoirement de se draper dans une démonstration émouvante d’objectivité.

Amazon Rain Forest Fires: Here’s What’s Really Happening

by Alexandria Symonds, August 23, 2019 in TheNewYorkTimes

These fires were not caused by climate change. They were, by and large, set by humans. However, climate change can make fires worse. Fires can burn hotter and spread more quickly under warmer and drier conditions.

When it comes to the future of climate change, widespread fires contribute a dual negative effect. Trees are valuable because they can store carbon dioxide, and that storage capacity is lost when trees burn. Burning trees also pumps more carbon into the atmosphere.
