In 1972, forty-two “top European and American investigators” predicted a rapidly approaching new ice age – based on an increase in snow and ice cover from 1967-1972.
The technique employed ….. depends on the averaging of information from standard and ‘infra-red satellite weather pictures.

A new study published in Geophysical Research Journal shows that the so-called Little Ice Age — a period stretching from 1500 to 1850 in which mean temperatures in the northern hemisphere were considerably lower than at present — exerted effects on the climate of South America.
Based on an analysis of speleothems (cave formations) in the Brazilian states of Mato Grosso do Sul and Goiás, the study revealed that in the seventeenth and eighteenth centuries, the climate of southwestern Brazil was wetter than it is now, for example, while that of the country’s Northeast region was drier.
The same Brazilian cave records showed that the climate was drier in Brazil between 900 and 1100, during a period known as the Medieval Climate Anomaly (MCA), when the northern hemisphere’s climate was warmer than it is now.

What’s most interesting is that while there’s been a slow, almost imperceptible increase in the phrase “climate change”, the search phrase “global warming” is getting far less use than it did when data was first collected, back in 2004. Right now, both “climate change”, and “global warming” have low interests.

There may be more than a quadrillion tons of diamond hidden in the Earth’s interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate the precious minerals are buried more than 100 miles below the surface, far deeper than any drilling expedition has ever reached.
The ultradeep cache may be scattered within cratonic roots — the oldest and most immovable sections of rock that lie beneath the center of most continental tectonic plates. Shaped like inverted mountains, cratons can stretch as deep as 200 miles through the Earth’s crust and into its mantle; geologists refer to their deepest sections as “roots.”
In the new study, scientists estimate that cratonic roots may contain 1 to 2 percent diamond. Considering the total volume of cratonic roots in the Earth, the team figures that about a quadrillion (1016) tons of diamond are scattered within these ancient rocks, 90 to 150 miles below the surface.

L ’hydrogène, un gaz peu abondant…
L’ hydrogène n’est présent qu’à concurrence de 1 ppm ( = une ‘partie par million’, soit 0,0001%) dans l’atmosphère : autant dire que c’est presque rien. D’où vient-il ? Peut-on en produire de grandes quantités à partir de ressources naturelles (géologie) ou artificielles (chimie) ? Autant de questions que de plus en plus d’industriels, de scientifiques, de politiques et de citoyens (?) se posent pour faire face à ce qu’il est convenu d’appeler la transition énergétique tant à l’ordre du jour, à raison ou à tort, là n’est pas l’objet de cet article. Comme nous le verrons par la suite, l’exploitation directe de l’hydrogène naturel n’est pas encore rentable et il faudra sans doute le produire à partir d’une autre source d’énergie, car il n’est pas lui-même une source d’énergie, mais au contraire un simple vecteur d’énergie.A l’heure actuelle il n’est donc pas exploité à une échelle suffisante en raison des contraintes géologiques et économiques, et il faut le synthétiser [1]. C’est ce que réalise aujourd’hui l’industrie principalement en vue de la fabrication de l’ammoniac pour les engrais ou des plastiques.…

Diesel cars may still be the most sensible option for many families who drive long distances, the transport secretary Chris Grayling said yesterday.
Despite a pledge to see the end of petrol and diesel vehicles on UK roads by 2040, Mr Grayling said new diesels were not destined for the scrapheap just yet.
He said: ‘If you are doing long distances on the motorway, maybe the new generation of diesel engines are the right option for now.

According to the report, if we are to take cooling demand seriously, the key stages to move towards a solution for cooling demand are:
Reducing the energy required for cooling: getting industry to adopt high efficiency cooling technologies and using maintenance to deliver optimum performance.
Reducing the need for cooling through better building design
Systems level thinking across built environment and transport
Harnessing waste resources: ‘wrong time’ renewables; waste cold; and waste heat.
Considering the strategies and skills required for installing appliances and maintaining them in order to maximise efficiency and reduce energy demand
Creating a model for delivery of affordable cooling to those in rural and urban communities based on the energy needs of local requirements, rather than imposing a ‘one size fits all’ approach

How have we measured the temperature of the ocean’s upper layer in the last 150 years? How does understanding physical processes and observational errors help to standardise climate data and understand climate change?
Sea surface temperature (SST) is also one of the climate indices with the longest histories of direct measurements. Because ocean makes up about 70% of the total Earth’s surface, changes in the temperature of its surface are a key factor for determining the global temperature of the planet’s surface.

The advocacy for widespread growth in renewable energy (especially wind, solar, and biomass) usage has increasingly become the clarion call of the anthropogenic global warming (AGW) movement. And yet more and more published research documents the adverse effects of relying on renewables.
Over the course of the last year, at least 30 papers have been published in the peer-reviewed scientific literature detailing the fatuity of promoting renewable energy as a long-term “fix” for climate change mitigation. A categorized list of these papers is provided below.

What if the worst is to come?” – Dr Carlo Testa.
2 July 2018 – “The Belgian department of solar physics research (SIDC) says we are about to touch 100; that is, a hundred days in which we do not see spots on our sun,” says Italian meteorologist Dr Carlo Testa.
During a time of few or no sunspots (a solar minimum) the Sun emits less energy than usual, says Dr Testa. “According to some scholars this situation could lead to climatic upheavals.”
Suffice it to recall, says Testa, that between 1645 and 1715 the most significant solar minimum of history, the Little Ice Age, occurred, bringing years and years marked by very strict winters that lasted until June. (…)

On 27 and 28 September 2017, eight large rockfalls occurred from the southeast face of El Capitan. These rockfalls resulted in one fatality and two serious injuries, and spurred a complicated rescue and temporary closure of the main road exiting Yosemite Valley. In order to manage these challenging events, the National Park Service (NPS) had a critical, immediate need for quantitative information about the sequence of rockfalls and the potential for additional activity.
Using new “structure-from-motion” photogrammetry techniques in conjunction with baseline laser-scanning data, scientists from the NPS, the U.S. Geological Survey, and the University of Lausanne, Switzerland rapidly analyzed these rockfalls. By comparing 3-dimensional (3D) models of the cliff before, during, and after the rockfalls, the researchers were able to pinpoint the exact locations, dimensions, and volumes of the rockfalls, along with the spatial and temporal pattern of their progression up the cliff.

James Hansen issued dire warnings in the summer of 1988. Today earth is only modestly warmer.
What about Mr. Hansen’s other claims? Outside the warming models, his only explicit claim in the testimony was that the late ’80s and ’90s would see “greater than average warming in the southeast U.S. and the Midwest.” No such spike has been measured in these regions.
As observed temperatures diverged over the years from his predictions, Mr. Hansen doubled down. In a 2007 case on auto emissions, he stated in his deposition that most of Greenland’s ice would soon melt, raising sea levels 23 feet over the course of 100 years. Subsequent research published in Nature magazine on the history of Greenland’s ice cap demonstrated this to be impossible.

Dr Peter Ridd has taken James Cook University to court protesting his sacking for what he says is, primarily, speaking-out about the lack of quality assurance in Great Barrier Reef science.
Dr Ridd spoke out initially about there being no quality assurance of Great Barrier Reef science – science that is arguably misused to secure billions of dollars of tax-payer funding. When the University tried to stop Dr Ridd doing this, Dr Ridd spoke out against University management – making all the documentation public including on his new website.

Energy access is the “golden thread” that weaves together economic growth, human development and environmental sustainability. The adoption of the Sustainable Development Goals in 2015, and the adoption of SDG 7.1 specifically – the goal to ensure access to affordable, reliable, and modern energy for all by 2030 – established a new level of political recognition for energy’s central role in development.
Improvements in technologies are offering new opportunities for making significant progress on the SDG goal on electricity access. The combination of declining costs for solar and decentralised solutions, cheaper and more efficient lighting and appliances, and new business models making use of digital, mobile-enabled platforms has increased the number of available solutions to cater to those currently without electricity access. But many challenges remain, particularly for clean cooking.

The main findings show that population growth and changes in our consumption patterns put unprecedented pressure on the planet’s natural resources:
Over 75% of the Earth’s land area is already degraded, and over 90% could become degraded by 2050.
Globally, a total area half of the size of the European Union (4.18 million km²) is degraded annually, with Africa and Asia being the most affected.
The economic cost of soil degradation for the EU is estimated to be in the order of tens of billions of euros annually.
Land degradation and climate change are estimated to lead to a reduction of global crop yields by about 10% by 2050. Most of this will occur in India, China and sub-Saharan Africa, where land degradation could halve crop production.
As a consequence of accelerated deforestation it will become more difficult to mitigate the effects of climate change
By 2050, up to 700 million people are estimated to have been displaced due to issues linked to scarce land resources. The figure could reach up to 10 billion by the end of this century.

Not a single EU state is meeting its climate targets, a new analysis by CAN Europe finds.
It’s been close to three years since countries worldwide signed the Paris Agreement, which obligates nations pledge to commit themselves to intending (or something like that) to reduce their greenhouse gas emissions in order to “safeguard the planet’s future”.
The language of the Agreement is in fact non-binding, and so one wouldn’t be surprised to learn that some signatories might not be living up to the agreement’s spirit.

After half a billion million years of climate change, I’m shocked, shocked I tell you, that life on Earth (and specifically corals) have so many ways to cope with the climate changing. After all, it’s natural (if you are trained by Greenpeace) to assume that corals can only survive in a world with one constant stable temperature just like they never had.

On June 8th, the California Department of Forestry and Fire Protection (Cal Fire) made its first official announcement via press release that 12 big Northern California wildfires in October 2017 were caused by problems associated with electric utility power lines.
The October 2017 Fire Siege involved more than 170 fires and burned at least 245,000 acres in Northern California. About 11,000 firefighters from 17 states and Australia helped battle the blazes. They concluded that 12 Wildfires in Mendocino, Humboldt, Butte, Sonoma, Lake, and Napa Counties were caused by Pacific Gas & Electric (PG&E) “power and distribution lines, conductors and the failure of power poles.”
The words “global warming” and “climate change” were conspicuously absent from the announcement even…

Trois révolutions énergétiques depuis à peine plus d’un siècle. Nous sommes entrés dans la troisième révolution énergétique. La première vit le jour avec la machine à vapeur et participa à l’essor du charbon, avec la seconde le moteur thermique dérôna le charbon au profit des hydrocarbures, et la troisième révolution industrielle, en cours, est technologique et basée sur les énergies ‘vertes’ ou énergies intermittentes et l’informatique ou le numérique. Cette problématique vient d’être abordée dans un excellent ouvrage paru en 2018 .
Peut-on dire que cette progression récente suivant ces trois phases majeures de la technologie s’est effectuée dans le sens d’un meilleur respect de l‘état de la Planète. Bien que cela soit le discours officiel, rien n’en est moins sûr. Pourquoi ? Tout simplement par le méconnaissance de tout un chacun à comprendre ou savoir ce qui est réellement utilisé dans les énergies vertes et numériques. L’actuelle ‘transition énergétique’ a bon dos et elle a toutes les vertus, elle est propre, quant aux les hydrocarbures, le charbon, l’uranium et CO2 (ennemi n° 1) ils ont tous les maux, et sont tous sales. Il n’est pas un jour où cette opposition nous est rappelée…

Voici quelques réflexions sur la théorie de l’acidification des océans. Selon cette théorie, le pH des océans diminuerait inlassablement, en raison du CO2 qui ne cesse de s’accumuler dans l’atmosphère.
• Les mesures directes de pH sont récentes et nous n’avons aucun recul. Selon les médias et les ONG écologistes, qui se basent sur le GIEC et sur certaines publications (e.g., Caldeira & Wickett 2003), le pH des océans aurait été de 8.25 en 1750. Cependant, il faut savoir que personne n’a jamais mesuré le pH des océans en 1750, puisque le concept de pH n’a été inventé qu’en 1909 (par le danois Søren P.L. Sørensen), et que les premiers appareils fiables pour mesurer le pH ne sont apparus qu’en 1924… Nous ne sommes donc pas certains de cette valeur de 8.25 pour 1750… La valeur de 8.25 est donc obtenue par des mesures indirectes et n’est donc pas certaine.
• A l’heure d’aujourd’hui, tous les pH sont possibles. Lorsqu’on dit que les océans actuels sont à un pH de 8.1, de quel océan parle-t-on? S’agit-il du pH moyen global? Si c’est de cela qu’on parle, quelle est l’incertitude sur la mesure? (i.e., l’écart-type?). Ceci n’est jamais indiqué. Il faut savoir que si l’on prend un jour de la semaine, tous les pH sont possibles dans les océans, comme l’illustre très bien la figure suivante.
