Ocean Acidification Background Context

by ‘Guest Blogger’, December 23, 2018 in WUWT

Obiter dictum. We acknowledge that seawater is basic and cannot truly acidify (pH<7). But that is a losing semantic quibble, not a winning skeptical argument. The generally accepted linguistic convention—for better or worse–is that lowering seawater pH means ‘acidification’. There is no doubt that adding dissolved CO2 does lower pH. The relevant questions are how much and whether that amount matters. This post answers both questions (a little, not much) without the two specific false alarms that motivated the ebook version.

There are certainly some ocean related AGW consequences beyond any scientific doubt. Henry’s Law requires that the partial pressures of atmospheric and dissolved ocean CO2equilibrate. Rising atmospheric CO2 must increase dissolved seawater CO2. That is long established simple physical chemistry.

This lowers pH by increasing carbonic acid. NOAA PMEL has documented this in the central Pacific at Station Aloha off Mauna Loa where sea surface pH has declined from 8.11 to 8.07 since 1991, as dissolved pCO2 increased from ≈325 to ≈360μatm while atmospheric CO2 increased from about 355 to 395 ppm. That is Δ0.04 pH in 24 years.

For those still blindly banging the ‘97%’ drum, here is a in-no-way-comprehensive list of the SCIENTISTS who publicly disagree with the current consensus on climate change –namely the IPCC’s catastrophic conclusions.

There are currently 85 names on the list. Though it is embryonic and dynamic.

Suggestions for omissions and/or additions can be added to the comment section below and, if validated, will serve to update the list.

Ignoring Climate Alarmists, UK Government Promises More Flights And Bigger Airports

by P. Homewood, December 18, 2018 in NotaLotofPeopleKnowThat

The Department for Transport publishes a long-awaited aviation strategy today that pledges to deliver “greater capacity at UK airports”.

It raises the prospect of airports other than Heathrow growing and accepting more flights if tough environmental and noise restrictions are met.

The strategy also outlines plans for the biggest overhaul of Britain’s airspace in more than 50 years to create new flight paths into the biggest airports. GPS-style technology will allow aircraft to fly along more accurate paths below 30,000ft instead of being led by ground beacons, which space planes out over a wide arc several miles across.

It will mean a considerable increase to the 600 or so dedicated flight paths that are in operation today

Ten years ago, @AlGore predicted the North polar ice cap would be gone. Inconveniently, it’s still there

by Antony Watts, December 16, 2018 in WUWT

On December 14, 2008, former presidential candidate Al Gore predicted the North Polar Ice Cap would be completely ice free in five years. As reported on WUWT, Gore made the prediction to a German TV audience at the COP15 Climate Conference:



Ce que la liste des participants à la COP24 dit sur la science climatique

by Rémy Prud’homme, décembre 2018, in MythesManciesMath.

La COP est une conférence internationale qui depuis 24 ans tient chaque année la réunion de la dernière chance pour sauver la planète. Vous croyez peut-être que la planète avait été sauvée lors de la COP21 à Paris. Erreur. Tout reste à faire. C’est ce qui justifie la COP24, qui se tient cette année en Pologne. Le secrétariat de la COP24 publie en ligne la liste de ses participants, sur près de 1100 pages.

Plus de 21 000 participants. Sans compter les 1500 journalistes accrédités, qui sont rémunérés par leurs médias, pas par les contribuables. Ces 21 000 participants sont pour 14000 des délégués des gouvernements, et pour 6000 des représentants d’ONGs prétendument intéressées et compétentes. (Le solde est composé de membres d’organisations du système des Nations-Unies).

Le coût de la fête est élevé. Les seuls frais de déplacement et de séjour pour cette COP de 15 jours s’élèvent sans doute (sur la base de 10000 € par participant) à plus de 200 millions d’euros. On pourrait y ajouter le coût du temps passé par les participants. S’ils y passent en moyenne une semaine, cela fait 21000 semaines, soit environ 500 personnes-années. A 50000 euros/an, 25 millions d’euros, qui s’ajoutent aux frais de déplacement. C’est de quoi doubler le niveau de vie annuel de 2 ou 3 millions d’enfants au Malawi.

Cop 24 : le voyage tous frais payés des 406 délégués guinéens

by F. Vahrenholtz & S. Lüning, 12 décembre 2018 in Contrepoints

Un article de NoTricksZone

La conférence sur le climat de Katowice bat son plein et diverses initiatives visant à réduire les émissions de dioxyde de carbone sont à l’ordre du jour : manger moins de viande, se chauffer moins, prendre moins l’avion. Dans ce dernier cas, bien sûr, la conférence confine elle-même à l’absurde.

Il aurait été facile de transformer la conférence en une réunion sur Internet avec retransmission en direct et commentaires en ligne. Mais il aurait manqué quelque chose à ce long et merveilleux voyage d’affaires avec ses réceptions, ses indemnités journalières et ses réunions d’avant Noël entre sauveteurs du climat. Cette fois-ci, plus de 22 000 participants se sont rendus en Pologne, la plupart confortablement en avion. Les délégations les plus nombreuses à la Conférence sur le climat venaient d’Afrique.

La Guinée envoie 406 délégués cette année, la République démocratique du Congo y est présente avec 237 participants et la Côte d’Ivoire envoie 191 ressortissants en Pologne. La liste des participants est disponible sur la page d’accueil de la conférence en format pdf et compte 1084 pages.

Climate change: COP24 fails to adopt key scientific report

by P. Homewood, December 9, 2018 in NotaLotofPeopleKnowThat

Attempts to incorporate a key scientific study into global climate talks in Poland have failed.

The IPCC report on the impacts of a temperature rise of 1.5C, had a significant impact when it was launched last October.

Scientists and many delegates in Poland were shocked as the US, Saudi Arabia, Russia and Kuwait objected to this meeting “welcoming” the report.

It was the 2015 climate conference that had commissioned the landmark study.

Marché européen du carbone : stop ou encore

by Jean-Pierre Schaeken, 7 décembre 2018 in ScienceClimatEnergie

Le système d’échange de quotas d’émission de l’UE,connu sous l’acronyme SEQE-EU ou en anglais  EU ETS, est instrument utilisé pour réduire les émissions de Gaz à Effet de Serre (GES) ou de CO2 pour faire court.  Il repose sur un principe de plafonnement et d’échange des droits d’émission. Il a été adopté par la Commission Environnement du Parlement européen, le 13 octobre 2003.

The Increasing Surface Mass Balance of Two Antarctic Glaciers

by Engel, Z.  et al., December 6, 2018 in CO2Sci/J.ofGlaciology

The polar regions of the Earth have long been depicted as canary-in-the-coal-mine sentinels of climate change, given that climate models project that CO2-induced global warming will manifest itself here, first and foremost, compared to other planetary latitudes. Consequently, researchers are frequently examining the Arctic and Antarctic for evidence of recent climate change.

Clearly, as demonstrated here and in other studies (see, for example, The Antarctic Peninsula: No Longer the Canary in the Coal Mine for Climate Alarmists and the references therein) there is a canary in the Antarctic alright, but it is alive and well. And these counter-observations do not bode well for climate models and their projections of CO2-induced global warming.

COP 24: The Church Of Climate Fear

by David Wojic, December 5, 2018 in ClimateChangeDispatch

The mainstream press coverage of the beginning of the Katowice climate summit is sad but fascinating.

There is a uniformly dogmatic sense of urgency based on fear, with very little news and a great deal of preaching.

Fear is the dominant theme.

I truly pity the people who hold these false beliefs, as they must be afraid of the future. But I am not sympathetic with the alarmism, because it makes people dangerous.

The preachers are calling on the faithful to change the world we live in, and not in a good way. Fear makes people angry and angry people are dangerous.

Here are just three examples of alarmist news coverage of the Katowice climate summit, a few among many.

Pulses of sinking carbon reaching the deep sea are not captured in global climate models

by Monterey Bay Aquarium Research Institute, December 3, 2018 in ScienceDaily

More than two miles below the ocean’s surface, microbes, worms, fishes, and other creatures great and small thrive. They rely on the transport of dead and decaying matter from the surface (marine snow) for food at these dark depths.

Up near the sea surface, carbon dioxide from the atmosphere is incorporated in the bodies of microscopic algae and the animals that eat them. When they die, these organisms sink to the depths, carrying carbon with them.

This supply of carbon to the deep sea isn’t steady. At times, months’ to years’ worth of marine snow falls to the abyss during very short “pulse” events.

In a new study published in the Proceedings of the National Academy of Sciences (PNAS), MBARI scientists and their collaborators show that there has been an increase in pulse events off the coast of California. They also show that, although such episodes are very important to the carbon cycle, they are not well represented in global climate models.

WMO Reasoning behind Two Sets of “Normals” a.k.a. Two Periods of Base Years for Anomalies

by Bob Tisdale, December 3, 2018 in WUWT

Most of us are familiar with the World Meteorological Organization (WMO)-recommended 30-year period for “normals”, which are also used as base years against which anomalies are calculated. Most, but not all, climate-related data are referenced to 30-year periods. Presently the “climatological standard normals” period is 1981-2010. These “climatological standard normals” are updated every ten years after we pass another year ending in a zero. That is, the next period for “climatological standard normals” will be 1991-2020, so the shift to new “climatological standard normals” will take place in a few years.

But were you aware that the WMO also has another recommended 30-year period for “normals”, against which anomalies are calculated? It’s used for the “reference standard normals” or “reference normals”. The WMO-recommended period for “reference normals” is 1961-1990. And as many of you know, of the primary suppliers of global mean surface temperature data, the base years of 1961-1990 are only used by the UKMO.
