Napoleon at Waterloo versus the volcano – Napoleon lost

by Anthony Watts, August 23, 2018 in WUWT


Napoleon’s defeat at Waterloo caused in part by Indonesian volcanic eruption

Electrically charged volcanic ash short-circuited Earth’s atmosphere in 1815, causing global poor weather and Napoleon’s defeat, says new research.

Historians know that rainy and muddy conditions helped the Allied army defeat the French Emperor Napoleon Bonaparte at the Battle of Waterloo. The June 1815 event changed the course of European history.

Two months prior, a volcano named Mount Tambora erupted on the Indonesian island of Sumbawa, killing 100,000 people and plunging the Earth into a ‘year without a summer’ in 1816.

Now, Dr Matthew Genge from Imperial College London has discovered that electrified volcanic ash from eruptions can ‘short-circuit’ the electrical current of the ionosphere – the upper level of the atmosphere that is responsible for cloud formation.

The findings, published today in Geology, could confirm the suggested link between the eruption and Napoleon’s defeat.

Scientists discover that the world contains dramatically more trees than previously thought

by Chris Money, September 2, 2015 in TheWashingtonPost


In a blockbuster study released Wednesday in Nature, a team of 38 scientists finds that the planet is home to 3.04 trillion trees, blowing away the previously estimate of 400 billion. That means, the researchers say, that there are 422 trees for every person on Earth.

However, in no way do the researchers consider this good news. The study also finds that there are 46 percent fewer trees on Earth than there were before humans started the lengthy, but recently accelerating, process of deforestation.

“We can now say that there’s less trees than at any point in human civilization,” says Thomas Crowther, a postdoctoral researcher at the Yale School of Forestry and Environmental Studies who is the lead author on the research. “Since the spread of human influence, we’ve reduced the number almost by half, which is an astronomical thing.”

Greenland Temperatures In 2017

by P. Homewood, July 1, 2018 in NotaLotofPeopleKnowThat


As we all know, Greenland is warming up rapidly, causing the ice sheet to melt faster and faster.

Well, according to the BBC and New York Times, at least.

Only one slight problem – the temperature record shows quite a different story.

There is certainly no evidence of rising temperature trends, and every likelihood that temperatures will plummet again when the AMO turns cold again.

World Energy Investment 2018

by Faith Birol, August 2018 in InternationalEnergyAgency


Total energy investment has fallen again…
2017 was the third consecutive year of decline in global energy investment with energy efficiency the lone sector of growth. Despite a 6% decline in spending, the electricity sector again attracted the largest share of energy sector investments, exceeding the oil and gas industry for the second year in row, as the energy sector moves toward greater electrification.

Holocene Sea Level Trends

by P. Homewood, August 22, 2018 in NotaLotofPeopleKnowThat


There seems to be a general acceptance about overall sea level trends during the Holocene.

There was naturally a very rapid rise in sea levels at the end of the ice age, until 6000 years ago, since when the rise has been much more gradual. Some research puts the rate of rise in the last 2000 years at 0.07mm/yr, and this reflects the fact that ice caps left over from the ice age are still melting, rather than that the world is warmer than before.

However, the impression is often given that, until the 20thC, this rate of rise has been pretty steady. This is despite the fact some of the authors of the above studies have warned of the existence of significant short-term fluctuations in sea level such that the sea level curve might oscillate up and down about this ~1 kyr mean state. [The above graph is based around 1000 year averages].

 

HH Lamb looked carefully at many expert studies in his day, and wrote about the very significant fluctuations they found. The following excerpts come from “Climate, History and the Modern World”:

1) The most rapid phases [of sea level rise] were between 8000 and 5000 BC, and that the rise of general water level was effectively over by about 2000 BC, when it may have stood a metre or two higher than today.

L’électricité intermittente. Une réalité et un prix.

by prof. Samuel Furfari, 21 août 2018 in ScienceClimatEnergie


Il ne se passe pas un jour sans que surgisse sur les réseaux sociaux ou dans les médias une discussion sur le prix de l’électricité. Pour les uns, le prix de l’électricité produite par les énergies renouvelables est bas et pour les autres au contraire il est élevé. Qui a raison ?

Il faut examiner l’ensemble de la filière de la génération d’électricité pour pouvoir juger et non pas comme on le fait trop souvent se cantonner à un seul aspect. Nous allons donc procéder étape par étape, de manière à présenter de manière objective ce qu’il en est. Nous allons d’abord constater que la génération d’électricité à partir d’énergies renouvelables est déjà une forte réalité et qu’elle est en croissance. Nous allons ensuite observer qu’il est crucial d’équilibrer constamment la génération d’électricité et sa consommation et que cela ne peut se faire que par l’intermédiaire d’un réseau. Nous passerons ensuite au caractère intermittent de certaines énergies renouvelables et verrons quelles en sont les conséquences pour enfin pouvoir aborder la réalité des prix aux consommateurs. Dans la dernière partie nous allons parler du prix de l’électricité que nous payons en tant que consommateur et qui n’est pas bien entendu le coût de production.

Le but de cet article est qu’à travers cette démarche pédagogique le lecteur puisse se faire sa propre opinion sur la question du prix de l’électricité d’origine renouvelable.

La filière hydrogène pour la production d’électricité, un mythe?

by JP Schaeken Willemaers, 20août 2018 in ScienceClimatEnergie


Depuis des décennies l’hydrogène revient régulièrement à l’ordre du jour comme moyen de stocker l’énergie pour ensuite la convertir en électricité. Cette filière est particulièrement prisée dans le cadre d’une politique bas carbone vu qu’elle n’émet pas de gaz à effet de serre (GES ) la combustion de l’hydrogène ne produisant que de l’eau. Bien entendu  la production de ce gaz doit elle-même « être  propre ».

Direct evidence of surface exposed water ice in the lunar polar regions

by Shaui Li et al., August 20, 2018 PNAS


We found direct and definitive evidence for surface-exposed water ice in the lunar polar regions. The abundance and distribution of ice on the Moon are distinct from those on other airless bodies in the inner solar system such as Mercury and Ceres, which may be associated with the unique formation and evolution process of our Moon. These ice deposits might be utilized as an in situ resource in future exploration of the Moon.

Integrated genomic and fossil evidence illuminates life’s early evolution and eukaryote origin

by Holly C. Betts et al., August 20, 2018 in NatureEcology&Evolution


We derive a timescale of life, combining a reappraisal of the fossil material with new molecular clock analyses. We find the last universal common ancestor of cellular life to have predated the end of late heavy bombardment (>3.9 billion years ago (Ga)). The crown clades of the two primary divisions of life, Eubacteria and Archaebacteria, emerged much later (<3.4 Ga), relegating the oldest fossil evidence for life to their stem lineages. The Great Oxidation Event significantly predates the origin of modern Cyanobacteria, indicating that oxygenic photosynthesis evolved within the cyanobacterial stem lineage. Modern eukaryotes do not constitute a primary lineage of life and emerged late in Earth’s history (<1.84 Ga), falsifying the hypothesis that the Great Oxidation Event facilitated their radiation…

Observing glaciers in “real time”

by Anthony Watts, August 20, 2018 in WUWT


From ETH Zurich and the “slow as molasses in winter” department.

Hot summers cause glaciers to melt. That not only changes the makeup of the landscape and hence the maps of Switzerland, it also affects every area of society. A new, dynamic glacier inventory makes the impact of climate change and the changing landscape visible.

The last time Swiss glaciers managed to grow at all was in 2001. Since then, the country’s 1,500 glaciers – as well as others elsewhere – have been suffering a slow but inexorable death. Until now, though, we have understood only partially how quickly they are really disappearing, and what effect that has on the landscape, people and animals. That is about to change, thanks to the Glacier Monitoring in Switzerland (GLAMOS) project. GLAMOS is working on behalf of various Swiss federal offices to put together a comprehensive inventory of the country’s glaciers – at an unprecedented level of detail.

America Had Lower CO2 Emissions Than Paris Climate Accord Signatories

by Stephen Moore, August 20, 2018 in ClimateChangeDispatch


Take a wild guess what country is reducing its greenhouse gas emissions the most? Canada? Britain? France? India? Germany? Japan? No, no, no, no, no and no.

The answer to that question is the United States of America. Wow! How can that be? This must be a misprint. Fake news. America never signed the Kyoto Protocol some two decades ago.

The Holocene Climate Optimum

by P. Homewood, August 19, 2018 in NotaLotofPeopleKnowThat


Booker commented the other day how one scientist claimed last week that we now have “the highest temperatures on Earth since the last ice age”. The BBC failed to even challenge this statement.

This certainly is not the first time I have heard claims (presented as fact) to this effect.

We have already seen concerted attempts to disappear the MWP, so it is time to reclaim the Holocene Optimum (so named for good reason), which is generally accepted to have run from about 9000 to 5000 years ago

Obviously we had no thermometers around in those days, so nobody knows what the average temperature of the Earth was then. There again, nobody really knows now either.

But there is plentiful evidence that many places were significantly warmer than now. I present some of this evidence below, though this is probably only skimming the surface: …

RSS Suspected Of “Serious Data Doping”, German Scientists Say…”Values Fudged To Fit Models”!

by  Dr. S. Lüning and Prof. F. Vahrenholt, August 19, 2018 in NoTricksZone


Temperatures can be measured from the ground and from satellites. Satellite data have two versions, UAH and RSS. The version of UAH (University of Alabama, Huntsville) makes a solid impression. The RSS version shows larger deviations and suggests a stronger warming.

How come?

Doping the data

Both datasets surely get their data from similar satellites. The explanation lies in a “post-processing” of the measured values ​​by the RSS group. In the chart below you can see the old version in red.

Weather and Climate in the Real World

by Tim Ball, August 18, 2018 in WUWT


All the trillions of dollars spent on AGW have not improved forecasting one bit. Instead, it diverted money that could have helped those large, primary sectors of society and economy that need better and more appropriate information. It is time to close all government weather offices or at least reduce their function to data collection determined by the end users.

Sécheresses (Grandes), étés caniculaires à travers les siècles

by La France Pittoresque, 1 août 2013


Quel est le degré de température de nos grands étés ? Ici revient l’insurmontable difficulté de fixer au juste, avant l’usage du thermomètre, l’intensité du froid ou de la chaleur. Un artifice fondé sur les rapports reconnus entre certains phénomènes naturels et les mouvements du thermomètre, fournit les mesures approximatives de nos grandes chaleurs et sécheresses.

De Humboldt a posé en principe que la végétation des arbres exige au moins une température moyenne égale à 11°. Le chiffre de cette température répond encore au point où la chaleur de l’air commence à devenir sensible. Ce degré assez fixe peut être pris pour le premier terme d’une échelle de nos grandes chaleurs. Messier a quant à lui constaté que le maximum de la chaleur à Paris, le 8 juillet 1793, a marqué 40°. C’est à peu près la plus haute température, excepté celle de l’été 1705 à Montpellier, observée en France, le thermomètre au nord, isolé, à l’ombre, à l’abri des réverbérations et à l’air libre.

Chemical nature of the 3.4 Ga Strelley Pool microfossils

by J. Allen et al., 2018 in GeochemicalPerspectiveLetters


The biogenicity of putative traces of life found in early-Archean rocks is strongly debated. To date, only equivocal lines of evidence have been reported, which has prevented a full consensus from emerging. Here we report elemental and molecular data from individual organic microfossils preserved within the 3.4 billion-year-old cherts of the Strelley Pool Formation, Western Australia. The present results support the growing body of evidence advocating their biogenicity, promoting them as the oldest known authentic organic microfossils. These microfossils consist of nitrogen- and oxygen- rich organic molecules that have been only slightly degraded despite experiencing temperatures of ~300 °C. Such molecular preservation emphasises the palaeobiological potential of the Earth’s oldest geological record, whilst providing a promising window into the early biosphere.

A Warm Period by Any Other Name – The Climatic Optimum

by Tim Ball, July 31, 2016 in WUWT


Hypsithermal, Altithermal, Holocene Optimum, Holocene Thermal Maximum, Holocene Megathermal, Anthropogene;

There is frustration and reward when an article appears on the same topic of an article you are completing – in this case the Holocene. Such was the case this week with Andy May’s article “A Review of temperature reconstructions.” Andy points out the basic problems of reconstruction using proxy data for the most recent half of the Holocene – an issue central to historical climate and climate change studies. His paper did not alter my paper except as it reinforces some arguments.

This article examines the entire Holocene and illustrates the history that influenced the studies. There are two distinct parts to the studies, the pre and post Intergovernmental Panel on Climate Change (IPCC). The former is a genuine scientific struggle with issues of terminology and reconstruction, and the latter a scientific struggle to impose a political perspective regardless of the evidence. Because of the damage done to climatology by the proponents of anthropogenic global warming (AGW), both parts require explanation.

Japan’s JMA Claim Of “Relatively Small” Urbanization Effect Likely An Understatement Of Multiple Degrees
