What would happen to Earth’s Climate and Weather if we had no Moon?

by A. Watts, February 15, 2019 in WUWT

A provocative hypothetical question: What if the Moon was not there? Video follows.

This giant rock lights up the night and can even change colors. So what would we do without it? Would we all need night vision goggles? How would it affect the ocean tides? Our seasons? Or our sleep cycles? Or would the consequences be far more drastic?

As the closest celestial body to our planet, the moon exerts a gravitational pull that governs much of what happens here on Earth Take the sea, for example. If you like surfing, you can thank the moon when the moon’s gravitational pull tugs on our spinning Earth, the oceans respond, giving us high tides in some parts of the world, and low tides elsewhere.

Carbon gas storage cavern is the best way to obtain clean energy from a fossil fuel

by Charles the moderator, February 13, 2019 in WUWT

The Research Center for Gas Innovation is developing technology to separate CO2 and methane in oil and gas exploration and store it in offshore salt caverns

Fundação de Amparo à Pesquisa do Estado de São Paulo

A set of technologies that is expected to have its first results four years from now is designed to resolve one of the world’s greatest oil and gas exploration challenges today: carbon dioxide (CO2) and methane (CH4) emission in the atmosphere.

The innovation, the result of a patent deposited in 2018, consists of injecting the CO2 and CH4 that comes from wells during oil extraction into salt caverns as a way to reduce the amount of carbon gas in the emissions.

A propos des indicateurs de température par satellites (1/2)

by J.C. Maurin, 8 février 2019, in ScienceClimatEnergie

A partir des notions intuitives de chaleur et température, les physiciens (Carnot, Thomson, Clausius, Maxwell, Boltzmann) arrivèrent progressivement à la notion scientifique de température thermodynamique. La Conférence Générale des Poids et Mesures  adopta en 1927 l’échelle thermodynamique proposée en 1911, puis l’unité kelvin en 1954.
La notion de température thermodynamique nécessite que l’équilibre thermique soit atteint, ce qui n’est pas le cas dans l’atmosphère de la Terre. Il n’existe pas une « température thermodynamique de l’atmosphère ». A défaut, on utilise une « moyenne des températures » mesurées en divers points de l’atmosphère. Mais la température thermodynamique étant une grandeur intensive, une moyenne, quelle que soit son élaboration, ne peut jouer qu’un rôle d’indicateur. L’usage est néanmoins d’utiliser le kelvin pour les indicateurs. On exprimera de préférence les variations des indicateurs sous forme relative. L’indicateur va être dépendant de l’échantillonnage (spatial et temporel) des mesures et surtout de son mode d’élaboration.

GWPF Call For Insect Decline Paper To Be Withdrawn

by P. Homewood, February 11, 2019 in NotaLotofPeopleKnowThat

London, 11 February: The scientific paper behind newspaper claims that insect populations were threatened with extinction was based on data known to be unreliable. That’s according to the Global Warming Policy Foundation, which today called for the paper to be withdrawn.

The paper, by US scientists Bradford C Lister and Andres Garcia, claimed that a rapid decline in insect populations in a rainforest in Puerto Rico was the result of rising temperatures. The Washington Post called the study “hyperalarming”, while the Guardian discussed climate change causing “insect collapse”.

However, the authors’ evidence that temperatures had, in fact, risen turns out to be based on a single weather station, which was known to be unreliable because of undocumented changes to equipment and location resulting in a substantial and abrupt increase in recorded temperatures in September 1992.

Since 1992, temperatures at this station have actually declined.

WORLD COOLING – BUT RAPID WARMING FORECAST

by David Whitehouse, February 7, 2019 in GWPF

Average global temperature has been falling for the last 3 years, despite rising atmospheric CO2 levels.

 

2018 was the fourth warmest year of the instrumental period (started 1850) having a temperature anomaly of 0.91 +/- 0.1 °C – cooler than 2017 and closer to the fifth warmest year than the third. But of course there are those that don’t like to say the global surface temperature has declined.

The Obvious Biomass Emissions Error

by Steve Goreham, February 7, 2019 in WUWT

When Thomas Edison established his Pearl Street power plant in New York City in 1892, he used coal for fuel, not wood. Wood fuel could not compete with the cost of coal in 1892 and it still can’t today. Nevertheless, burning of biomass is widely regarded as sustainable and promoted as a solution for climate change, especially in Europe.

Today, Europe produces about 17 percent of its energy and 29 percent of its electricity from renewable sources. Biomass accounts for about 19 percent of the electricity generated from renewables. Since 2000, Europe’s biomass consumption for energy production is up 84 percent.

For example, biomass fuel produced 18 percent of Denmark’s electricity in 2017. For the last two decades, Denmark has been reducing coal-fired power plant output, but adding biomass-powered plants. Since 2000, Denmark’s use of coal fuel for electricity decreased 63 percent. But the use of biomass fuel for electricity in Denmark increased by a factor of five, almost exactly replacing the decline in coal output. About three-quarters of the biomass consumed by Denmark is wood, with most of it imported.

40 ans après la révolution en Iran, l’arme géopolitique du pétrole a fait long feu

Réponse à la pétition “Plus d’ambitions climatiques”

by SCE-info, 31 janvier 2019 in ScienceClimatEnergie

Chers Collègues scientifiques signataires de la pétition (ici),

Vous avez signé une pétition en tant qu’académique scientifique. Tous les signataires le sont-ils ? Avez-vous remarqué des signataires qui n’ont pas existé ou qui sont décédés ? Trofik Lysenkom, inconnu sur Google, par contre Trofim Lysenko a bien existé (1898-1976) et reste de triste mémoire dans le monde scientifique. Outre cet aspect cocasse, il y a plus grave : en tant que signataires vous cautionnez que la science est dite (‘the science is settled’) et si tel est bien le cas alors vous ignorez de très nombreuses publications scientifiques, émanant de scientifiques de ‘haut vol’ qui montrent que le doute est permis, qu’il doit rester la règle en science, et que la climatologie ne se résume pas aux énoncés simplistes de la pétition (qui ne mentionne aucune références pour argumenter). Bien entendu vous avez peut-être lu des articles et vous vous êtes fait une opinion. Dans ce cas, vous avez exercé votre esprit critique et vous avez tout compris de la climatologie. Il n’y a donc plus de doute pour vous, et du fait de votre signature la science est effectivement dite. L’essentiel des politiques et médias, bien qu’ils n’aient pas une grande connaissance scientifique, pensent comme vous.

Dans cet article, qui se veut une ouverture au débat, nous allons donner notre point de vue aux questions qui ont suscité votre adhésion. Nous ne ferons pas de politique, notre site Science, Climat et Energie (SCE) ayant une vocation scientifique. Nous souhaitons cependant que ceux qui n’ont pas fait l’effort de lire la manière dont les publications sont validées par le GIEC aillent consulter le site du GIEC.

Vous l’aurez compris, la climatologie est une science jeune, fort complexe, et contrairement aux affirmations et ‘matraquages’ quotidiens, elle est loin d’être comprise.

Passons maintenant aux éléments factuels.

Is China’s plan to use a nuclear bomb detonator to release shale gas in earthquake-prone Sichuan crazy or brilliant?

by Charles the moderator, January 31, 2019 in WUWT

From The South China Morning Post

  • Scientists have developed an ‘energy rod’ that can fire multiple shock waves to frack sedimentary rock at depths of up to 3.5km

  • China has the world’s largest reserves of natural gas but current mining technology makes most of it inaccessible

China is planning to apply the same technology used to detonate a nuclear bomb over Hiroshima during the second world war to access its massive shale gas reserves in Sichuan province. While success would mean a giant leap forward not only for the industry but also Beijing’s energy self-sufficiency ambitions, some observers are concerned about the potential risk of widespread drilling for the fuel in a region known for its devastating earthquakes.

Despite being home to the largest reserves of shale gas on the planet – about 31.6 trillion cubic metres according to 2015 figures from the US Energy Information Administration, or twice as much as the United States and Australia combined – China is the world’s biggest importer of natural gas, with about 40 per cent of its annual requirement coming from overseas.

Venezuela : quelle leçon retenir de l’échec de ce champion du pétrole ?

by Samuel Furfari, 29 janvier 2019 in  Contrepoints

La révolution bolivarienne financée par le pétrole a complètement appauvri le Venezuela. Les idéologues socialistes avaient tout faux depuis le début.

…

Le paradoxe est encore plus étrange car le pays est très riche en ressources naturelles. Avec 303 milliards de barils (18 %  du total mondial), le Venezuela détient les plus grandes réserves prouvées de brut au monde, loin devant l’Arabie Saoudite qui en possède 266. Pour mesurer leur ampleurs, observons que ces réserves correspondent à celles combinées de la Russie, des États-Unis et de l’Iran. Il possède également 6 400 milliards de m3 de gaz naturel – 3,3 % des réserves mondiales –  soit près de quatre fois les réserves de la Norvège, considérée en Europe comme un grand du gaz.

La plupart des réserves de pétrole prouvées du Venezuela sont situées dans le bassin du fleuve Orinoco, où 220,5 milliards de barils de pétrole lourd gisent, pratiquement inexploités. Même s’il n’est pas de première qualité, c’est quand même du pétrole. La principale zone de production se trouve dans le bassin de Maracaibo, où l’on pompe près de 50 % du pétrole vénézuélien.

70,000 March in Brussels to Demand Climate Action

by Eric Worrall, January 29, 2019 in WUWT

A message to French Yellow Vests that greens and EU supporters can field large groups of demonstrators. But half the pro-climate action marchers were school children.

I’m disgusted by how greens seem to think it is OK to use children as political pawns in their nasty game.

The school children, half of the climate action marchers, have no idea about the real world. They have never experienced the misery of watching their meagre weekly pay packets taxed away by distant green politicians who have no empathy or concern for the problems of ordinary people.

New Paper: Modern Warming Was Driven By ‘Primarily Natural’ Factors. Global Cooling Has Now Begun.

by K. Richard, January 21, 2019 in NoTricksZone

Four climate scientists assert (1) the last ~130 years of temperature changes fit “perfectly” into statistical indices of natural variation, and (2) a long-term deep cooling of the Earth system has recently commenced.

An analysis published in the journal Atmospheric and Climate Sciences by 4 climate scientists reveals the 1880-2013 temperature changes fit “perfectly” (0.9 correlation) into a calculation utilizing 15,295 periodic functions of natural variation.

The authors claim this affirms that the non-anthropogenic “major climate factors” (i.e., solar-cloud and ENSO forcing) can still be considered the “main reason” driving modern warming (Lakshmi and Tiari, 2015; Hassan et al., 2016; McLean, 2014; Yeo and Kim, 2015;  Wielicki et al., 2002; Douglass and Knox, 2014; Sejrup et al., 2010; Large and Yeager, 2012; Irvine, 2015; Cess and Udelhofen, 2003; Clark, 2010; Ogurtsov et al., 2017; Fleming, 2018; Zherebtsov et al., 2019).

Hump day hilarity – the progression of climate narrative names

by Anthony Watts, January 16, 2019 in WUWT

I had a predictable and laughable Twitter dialog today with the editor of the bought and paid for climate activist site known as “The Carbon Brief”. He was bent out of shape because I pointed out that while he thought the reason for the stepping down of Lord Lawson at The Global Warming Policy Foundation in the UK was due to the lack of traffic and interest in the organization, it [the lowered traffic] really is because of two reasons:

  1. The public is getting bored with it, possibly due to all the fear-mongering promoted by irresponsible journalists.

  2. There’s been a shift from the use of the term “global warming” to other terms, perhaps in a desperate bid to “keep it fresh”. …

Il y a pléthore de gaz et de pétrole ! Vous êtes au courant ?

by Michel Gay, 13 janvier 2019 in Contrepoints

Du gaz et du pétrole de schiste sont découverts à profusion dans le monde, notamment aux États-Unis. Qui en parle dans nos grands media ? Serait-ce politiquement incorrect de l’évoquer ?

LE SUCCÈS DU PARI DU GAZ ET DU PÉTROLE DE SCHISTE

Le Texas aux États-Unis regorge de pétrole et de gaz de schiste au point que les gazoducs existants sont saturés ! Le gaz doit même être « torché » ou « éventé ».

En attendant la mise en service de nouvelles capacités de transport, la production doit être réduite faute de pouvoir exporter les quantités extraites. La production de pétrole de schiste doit aussi être réduite en parallèle car il est extrait avec le gaz (et vice-versa).

Des projets sont en développement pour évacuer le gaz vers le Golfe du Mexique pour le liquéfier (GPL) et pouvoir ainsi l’exporter par bateau méthanier.

PREMIER PRODUCTEUR DE PÉTROLE

Les États-Unis ont dépassé la Russie et l’Arabie Saoudite pour devenir le premier producteur de pétrole brut  en 2018 a annoncé l’agence américaine de l’énergie (EIA).

Après avoir stagné autour de 6 millions de barils par jour (Mb/j) en moyenne de 1933 à 2013, la production a grimpé à 9,4 Mb/j en 2017, puis à 10,4 Mb/j en 2018, et elle passera à 11,5 Mb/j 2019.

La surabondance de gaz de schiste associé à l’extraction du pétrole de schiste a fait chuter les prix au terminal gazier à l’ouest du Texas jusqu’à 1 dollar par million d’unité thermique britannique (dollar/MM-Btu), alors qu’il vaut 13 à 14 dollars/MM-Btu sur le marché européen.

Another Climate Propaganda Story Promoting the Normal as Abnormal

Other stories focus on a pattern or change in a pattern again with the idea that it is new or abnormal. Headlines like this one from 2012, “Why have there been more tornadoes than usual this year?” Often, they are suggestive such as this 2017 New York Times story. “The 2017 Hurricane Season Really Is More Intense Than Normal.” When you read the story, you find, as is usually the case, that the caveats at the end indicate it is not unusual. The problem is the headline already set the pattern in the public mind.

Kerala Floods “Likely Due To Climate Variability, Not AGW”–New Study

by P. Homewood, January 5, 2019 in NotaLotofPeopleKnowThat

…

Since there is no increase in mean and extreme precipitation in Kerala over the last six decades, the extreme event during August 2018 is likely to be driven by anomalous atmospheric conditions due to climate variability rather anthropogenic climate warming. The severity of the Kerala flood of 2018 and the damage caused might be affected by several factors including land use/ land cover change, antecedent hydrologic conditions, reservoir storage and operations, encroachment of flood plains, and other natural factors. The impacts of key drivers (anthropogenic and natural) on flood severity need to be established to improve our understanding of floods and associated damage.

Heads up Newfoundland & Labrador: polar bear season has begun

by Susan Crockford, January 2, 2019 in PolarBearScience

There is now enough sea ice off southern Labrador and the northern tip of Newfoundland for Davis Strait polar bears to come ashore looking for food. Baby seals won’t be available for months yet. And since winter is the lean season for these bears, some may seek food sources onshore. The bears come down from the area of Hudson Strait and southern Baffin Island: as the sea ice expands south, so do the bears.

January 2018:  Worst-case global warming scenarios not credible: Study

PARIS (AFP) – Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday (Jan 17) which, if correct, voids worst-case UN climate change predictions.

A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature.

February:  ‘Sinking’ Pacific nation Tuvalu is actually getting bigger, new research reveals

The Pacific nation of Tuvalu — long seen as a prime candidate to disappear as climate change forces up sea levels — is actually growing in size, new research shows.

A University of Auckland study examined changes in the geography of Tuvalu’s nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery.

It found eight of the atolls and almost three-quarters of the islands grew during the study period, lifting Tuvalu’s total land area by 2.9 percent, even though sea levels in the country rose at twice the global average.
