The global body tasked with naming geological eras, the International Commission on Stratigraphy, has rejected the proposed Anthropocene epoch, the controversial ‘geological’ epoch in which mankind allegedly dominates natural processes. The international commission has now rejected the proposal and has instead split the Holocene Epoch into three different geological ages, all of which were primarily shaped by natural, not human factors.

In his posthumously published book “Factfulness,” the Swedish statistician Hans Rosling describes a paradox: “The image of a dangerous world has never been broadcast more effectively than it is now, while the world has never been less violent and more safe.”
A case in point: natural disasters. The earth will always be volatile, but despite recent fires, volcanoes, and hurricanes, humanity currently is experiencing a stretch of good fortune when it comes to disasters.
It’s difficult to be “factful” about disasters—the vivid trauma of each event distracts observers from the long-term decrease in destructiveness.
But climate activists make the problem worse by blaming every extreme weather event on human-caused climate change, hoping to scare people into elevated concern.

Germany’s wind and solar experiment has failed: the so-called ‘Energiewende’ (energy transition) has turned into an insanely costly debacle.
German power prices have rocketed; blackouts and load shedding are the norm; and its idyllic countryside has been turned into an industrial wasteland, with its forests, no exception (see above).
Hundreds of billions of euros have been squandered on subsidies to wind and solar, all in an effort to reduce carbon dioxide gas emissions. However, that objective has failed too: CO2 emissions continue to rise.

La fourniture d’électricité est essentielle au développement économique d’une nation et à son harmonie politique et sociale. Les profondes mutations subies actuellement par le système électrique dans lequel la part des énergies renouvelables intermittentes ne cesse d’augmenter, présentent des risques pour cette fourniture. Il importe d’en assurer la sécurité. Evaluer le coût d’un blackout est donc un élément d’information essentiel, qui devrait être pris en compte dans toute décision future d’investissement en matière de génération de puissance.

In Spain, has been following my lead on the poor quality of weather stations that produce record-high temperatures. I recently pointed out how the tentative all time high temperature in Africa could very well be due to being at an airport. I also pointed out that high temperature records in the Los Angeles area could be a product of poor siting. Such as this station on the roof of the Santa Ana fire station:

All around the world the climate druids are at work.
Show me the error bars
Once upon a time a scientist talked about thirty year trends and anachronistic things like “confidence intervals”. Now, thanks to the discovery of Unscience, any noisy, random short data is fair game to be declared undeniable climate change. Periods of flooding also qualify, as do periods of nice weather, though strangely no one mentions those. Where are the headlines? If climate change caused drought on the East Coast of Australia, it’s also causing average rain and good crops in Western Australia.
In terms of scientific data analysis we don’t get that many droughts or six-day-August-heatwaves to analyze. They’re complex phenomena caused by multiple factors and we only have short records. This makes them ideal to be oversold to hapless folk as a “sign” of climate change.

Somebody said economists try to predict the tide by measuring one wave. This puts them in the same league as climate scientists trying to predict the climate by measuring one variable, CO2. It is no surprise that an amalgam of the two, climate and economics, produces even worse results, but that is what happened early in the anthropogenic global warming (AGW) deception.

Silica is needed by a group of marine algae (the microscopic plants of the oceans) called diatoms, who use it to build their glassy cell walls (known as frustules).
These plankton take up globally significant amounts of carbon — they remove carbon dioxide from the atmosphere via photosynthesis, and act as a natural carbon sink when they die and fall to the bottom of the ocean — and form the base of the marine food chain.
The researchers are also planning to use more complex and realistic computer models to delve deeper into the potential changes in the global silica cycle since the last glacial maximum. These might include more accurate representations of ocean currents, recycling of silica in the water column, and potential changes to the marine algal community.

A prominent feature of all climate model projections is their prediction that temperatures should be rising in response to ever-increasing concentrations of greenhouse gases. However, for the past two decades global surface air temperatures have not warmed to the degree predicted by the models, which lack of warming has been a conundrum to the climate alarmist movement.

De tous temps les hommes se sont intéressés au climat et ont tenté de prévoir son évolution. Dès l’Antiquité il était connu que des caractéristiques géographiques comme la latitude mais aussi l’altitude ou le voisinage de vastes étendues d’eau avaient une grande influence sur le climat. Sur cette base les climatologues ont été amenés à distinguer différents types de climats tels que tropical, désertique, tempéré, polaire, etc. Ensuite, il est progressivement apparu que le climat est un système extrêmement complexe qui dépend de l’activité solaire ainsi que de la distance et de l’orientation de la Terre par rapport au Soleil, facteurs qui varient à des échelles de temps très différentes.

With wildfires engulfing over 620,000 acres of California, there’s been a concerted media campaign to single out man-made global warming as the primary force behind the deadly blazes.
But that’s not what the data suggests, according to University of Washington climate scientist Cliff Mass.
“So there is a lot of misinformation going around in the media, some environmental advocacy groups, and some politicians,” Mass wrote in the first of a series of blog posts analyzing the California wildfires.

Syracuse University professor uses ancient marine sediment as benchmark for present, future climate models
SYRACUSE, N.Y. – Researchers at Syracuse University are looking to the geologic past to make future projections about climate change.
Christopher K. Junium, assistant professor of Earth sciences in the College of Arts and Sciences (A&S), is the lead author of a study that uses the nitrogen isotopic composition of sediments to understand changes in marine conditions during the Paleocene-Eocene Thermal Maximum (PETM)–a brief period of rapid global warming approximately 56 million years ago.
Junium’s team–which includes Benjamin T. Uveges G’17, a Ph.D. candidate in A&S, and Alexander J. Dickson, a lecturer in geochemistry at Royal Holloway at the University of London–has published an article on the subject in Nature Communications (Springer Nature, 2018).

Anybody who thinks China is rapidly shifting to renewable energy needs to look at the latest electricity data from the China Energy Portal.
Whilst wind and solar generation has increased by 51 TWh year-on-year in Q2, thermal has increased by 176.9 TWh.

In what amounts to dissension from National Aeronautics and Space Administration (NASA) climate change policy, a series of just-released studies by working-level scientists prove that geological and not atmospheric forces are responsible for melting of Earth’s polar ice sheets.
