The Katla volcano, hidden beneath the ice cap of Mýrdalsjökull glacier in Iceland, has historically erupted violently once every 40-80 years. In-as-much as it’s last such eruption took place one hundred years ago, in 1918, Katla’s next eruption is long overdue.
An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned.
A new study by Icelandic and British geologists showed that Katla is emitting enormous quantities of CO2 – at least 20 kilotons of CO2 every day. Only two volcanoes worldwide are known to emit more CO2, Evgenia Ilyinskaya a volcanologist with the University of Leeds told the Icelandic National Broadcasting Service RÚV.

One of my favorite sayings is, “We didn’t leave the Stone Age because we ran out of stones.” Technically we never left the Stone Age because we use more rocks now than we did in the Stone Age.
And we never left the “Wood Age.” There was no energy transition from biomass (wood) to fossil fuels. Coal piled on top of biomass, oil piled on top of coal and natural gas piled on top of oil

Despite all the signals being sent from every direction suggesting global warming is leading to more frequent and intense hurricanes, even the warmist NOAA is forced to confess that this has not been the long-term case.

Nearly seven years ago, on December 7th, 2011, the Free Market Environmental Law Clinic’s (FME Law) sought public records from the University of Arizona related to the Mann-Bradley-Hughes temperature reconstruction that looks like a hockey stick, and development of an Intergovernmental Panel on Climate Change (IPCC) report. They refused much of the request and FME Law sued. Now (on September 18th, 2018) legal counsel for the University informed FME Law that they were done, that they would be withdrawing their appeal of the trial court’s decision, end the case and disclose the records.
Included in the release will be emails that, for example, provide the full context of the discussions between Michael Mann and colleagues and Chick Keller on whether there was a medieval warm period and a little ice age. Mann, Bradley and Hughes (MBH) were the authors of the “hockey stick” graph that became the icon of climate alarmism. Dr. Keller was, at the time, Director of the Institute of Geophysics and Planetary Physics at the Los Alamos National Lab and affiliated with the University of California at San Diego, and wanted to reconcile data which appeared to refute the MBH papers. Also within this collection will be the full discussion on events surrounding an effort to remove editors of journals willing to publish peer-reviewed papers that contradicted the MBH and related papers on which climate alarmism was built. This collection of emails is particularly important in that they will provide the full context of Climategate emails that have been described as “cherry picking.”

The German ADAC association, the equivalent of America’s AAA, carried a CO2 comparison for a variety e-autos and combustion engine cars. The results were very surprising, says German magazine Autobild here.
Today’s electric cars are being pushed as a clean and environmentally friendly alternative, while diesel and gasoline burning engines are being villainized as polluters and climate killer …

Les côtes de Flandre n’ont pas toujours été aussi paisibles qu’aujourd’hui, et je n’oublie pas le raz-de-marée du 31 janvier 1953 qui toucha les Pays-Bas et notre littoral, faisant plus de 1800 morts et des dégâts considérables. (photo : à Ostende).
Pêchés dans diverses chroniques et ouvrages (notamment “La Flandre mystérieuse” de Saint Hilaire), j’en ai fait une compilation qui n’a bien entendu aucune prétention scientifique ou historique, mais ces événements avaient laissé une trace dans la mémoire populaire, trace qui a hélas fortement tendance à s’effacer.
J’y ajoute quelques événements survenus en France et aux Pays-Bas, dont on peut raisonnablement penser au vu de leur localisation, qu’ils eurent des conséquences sur nos côtes

The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. These are long term values, estimated for the 261-year period 1750-2011 and they apply to the “baseline” of the Schwabe ~11-year solar (or sunspot) cycle, which we will simply call the “solar cycle” in this post. The baseline of the solar cycle is the issue since the peaks are known to vary. The Sun’s output (total solar irradiance or “TSI”) is known to vary at all time scales (Kopp 2016), the question is by how much. The magnitude of short-term changes, less than 11 years, in solar output are known relatively accurately, to better than ±0.1 W/m2. But, the magnitude of solar variability over longer periods of time is poorly understood. Yet, small changes in solar output over long periods of time can affect the Earth’s climate in significant ways (Eddy 1976) and (Eddy 2009).

Godfrey Dack writes in with this:
Everyone will be familiar with the difficulty of listening to a conversation held with a friend in a crowded room with many other conversations going on at the same time. So it is with many fields of scientific investigation where it is difficult to tease a particular trend out from masses of data. In the first case, we could call the friend’s conversation ‘The Signal’, and the background conversations ‘The Noise’.
In looking at climate data, trends (the signal) can be graphically represented by a (generally) smooth curve, usually flanked by a range of experimentally predicted or actually measured values (the noise). Joining up every point on a graph of such data would give a jagged line which could be thought of as a combination of many alternating functions over a wide range of frequencies.

Even though coal’s lead has been cut from 17 to 2 States since 2007, it’s still in first place. Numbers in parentheses reflect the change since 2007.
Coal: 18 (-10)
Natural Gas: 16 (+5)
Nuclear: 9 (+3)
Hydroelectric: 6 (+2)
Petroleum: 1 (0)
What about wind and solar? Let’s ask Dean Wormer!

Yes… I know entropy falls under the Second Law of Thermodynamics… But I doubt the author of the Clean Technica article does. [Author’s note: By “falls under the Second Law of Thermodynamics, I don’t mean decreases; I mean it falls under the “jurisdiction” of the Second Law of Thermodynamics.]

Among today’s Real Clear Energy headlines, almost totally unrelated to energy: What Will Persuade Conservatives To Fight Climate Change?

Michael Bloomberg est un milliardaire américain (pas un petit : l’une des vingt plus grosses fortunes mondiales), membre du parti démocrate, ancien maire de New York. C’est naturellement un farouche défenseur de l’environnement, ce qui lui a valu d’être nommé par le Secrétaire Général des Nations-Unies « envoyé spécial pour l’action climatique ». On ne peut pas le soupçonner de minorer le développement des énergies propres.
LES INVESTISSEMENTS DANS L’ÉNERGIE « PROPRE » SONT EN DÉCLIN
Le rapport que publie l’entreprise qu’il dirige (en fait une filiale consacrée aux énergies nouvelles) montre que les investissements dans « l’énergie propre », définie comme l’éolien et le photovoltaïque, ont diminué dans la plupart des pays du globe au cours des années 2010. Le point haut a été atteint en 2011. Depuis cette date, les investissements stagnent ou diminuent, à des taux divers selon les pays et les années.
La COP21, en 2015, devait sauver le monde grâce à des investissements massifs dans ces domaines. Elle n’a rien fait de tel. Au contraire, les années 2016, 2017 et 2018 sont marquées par une accélération de la baisse des investissements.

This article claim ships will “be able to sail right over the North Pole” by 2050 due to warming, but at the same time say ship tracks will make more clouds and cool the Arctic. Of course, anything is possible with the help of climate models.
More ships and more clouds mean cooling in the Arctic
With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole – something not previously possible for humankind.

Dans les années 80, la découverte dans les archives glaciaires d’une corrélation entre température et taux de CO2 permit de soupçonner une influence anthropique sur le climat: les taux mesurés depuis 1958 étaient supérieurs aux taux des archives glaciaires.
L’IPPC (GIEC) fut créé en 1988 par 2 organismes: United Nations Environment Programme (UNEP) et World Meteorological Organization (WMO). Le GIEC attribue l’intégralité de la hausse du taux de CO2 depuis un siècle à l’influence humaine. Pour les dernières décennies, nous examinerons ici les mesures disponibles, les corrélations CO2 / température, enfin le modèle anthropique GIEC sera confronté à un modèle concurrent.
