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 . C’est ce que réalise aujourd’hui l’industrie principalement en vue de la fabrication de l’ammoniac pour les engrais ou des plastiques.

Unearthed new evidence (Mangerud and Svendsen, 2018) reveals that during the Early Holocene, when CO2 concentrations hovered around 260 ppm, “warmth-demanding species” were living in locations 1,000 km farther north of where they exist today in Arctic Svalbard, indicating that summer temperatures must have been about “6°C warmer than at present”.
Proxy evidence from two other new papers suggests Svalbard’s Hinlopen Strait may have reached about 5 – 9°C warmer than 1955-2012 during the Early Holocene (Bartels et al., 2018), and Greenland may have been “4.0 to 7.0 °C warmer than modern [1952-2014]” between 10,000 and 8,000 years ago according to evidence found in rock formations at the bottom of ancient lakes (McFarlin et al., 2018).
In these 3 new papers, none of the scientists connect the “pronounced” and “exceptional” Early Holocene warmth to CO2 concentrations.

Hurricane threat to East Coast due to natural factors
First at his most recent Saturday Summary, the 40-year meteorologist first warns that in-close developing hurricanes of the sort seen in the 1930s are a risk to the US East Coast this year, due the current Atlantic temperature pattern. The reason has nothing to do with CO2 in the atmosphere, but because of natural sea surface temperature cycles.
Sea surface temperatures see “pretty dramatic turnaround”
by Dr. Duane Thresher, April 26, 2017 in PrincipiaScientificIntern.
Climate model/proxy research that does not show global warming will not get published or funded because of:
- Non-publication of negative results (no global warming found)
- Fearful self-censorship
- Conflict of interest (a need to get results, regardless of validity, that further careers)
- Corrupt fanatical unqualified “working” scientists
- Censorship by established scientists in a fundamentally-flawed peer review process (peers are all-too-human competitors)
- Corruption of climate science overall

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.

The Climategate emails expose to our view a world that was previously hidden from virtually everyone.
This formerly hidden world was made up of a very few players. But they controlled those critical Intergovernmental Panel on Climate Change (IPCC) processes involv- ing the temperature records from the past, and the official interpretation of cur- rent temperature data. They exerted previously unrecognized influence on the “peer review” process for papers seeking publication in the officially recognised climate science literature from which the IPCC was supposed to rely exclusively in order to draw its conclusions.

L’ Anthropocène est la dernière création marketing d’un géologue. Avec un certain succès médiatique alors que les scientifiques s’y opposent fermement. Pourquoi ?
by Marc Morano, July 13, 2018 in ClimateDepot
The ‘average’ world temperature for June 2018 was +0.21 deg C above the 1981 – 2010 mean. That represented a decline of about 0.65 deg C from the all-time high of this 39-year record, which was reached in early 2016. The 0.65 deg C decline represented more than 75% of the amount by which the average temperature had exceeded the 1981 – 2010 mean at the highest point. Suddenly the fact that some large number of “all-time highs” was being set at the end of June does not seem very significant.”

Arctic sea ice volume melt rates have started to slow, with ice volume 4th highest since 2003.
Temperatures near the pole have been below normal almost every day this summer.

• Global warming and polar ice-melt not contribute to sea level rise.
• Melting of huge volume of floating sea-ice around polar region cool ocean-water preventing thermal expansion.
• Polar ice melting re-occupy same volume of the displaced water causing no sea level rise.
• Gravitational attraction of the earth plays a dominant role against sea level rise.
• Melting of land ice in the polar region allow crust to rebound elastically for isostatic balancing through uplift should cause sea level to drop relatively.

A University of Aizu team has identified two distinct Indo-Pacific processes shaping the unique features and extraordinary ferocity of super El Ninos. A systematic analysis of these processes and their interactions will improve forecasts of the elusive super El Ninos, the researchers claim.
Extremely warm sea surface temperatures are a notable feature of the super El Ninos that occurred in 1972, 1982, and 1997. The fact that Pacific Ocean processes responsible for generating regular El Ninos could not explain this key signature of super El Ninos came as a big shock,” says Dachao Jin, co-author of the study.

If you were to believe the mainstream media, you’d think our world is burning up. But that is not true.
Yes, there were places on our planet where it was warmer than normal today. But many parts of the world displayed normal or even colder than normal temperatures.
Look at all of the white and blue on this map.

A new German paper assesses wind energy in Europe . The results are devastating. It concludes that wind energy requires almost 100% backup and that the more capacity that gets installed, the greater the volatility.
The paper appearing at the VGB, authored by Thomas Linnemann and Guido Vallana, finds that “the total wind fleet output of 18 European countries extending over several thousand kilometers in north-south and east-west direction is highly volatile and exhibits a strong intermittent character.”
In other words the power supply across the European grid fluctuates wildly and thus cannot work well. The paper’s abstract continues: …

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

According to the Guardian (9 July 2018), there is a “global heat wave” going on right now.
In Siberia, the heat is supposedly “completely unprecedented” and will surely (we are told) impact Arctic sea ice — the habitat of the iconic polar bear. Yet a comparison of previous years shows little to no impact on sea ice: there is more ice present than there was in 2007.
