“It is tempting to say that the record low we are seeing this year is global warming finally catching up with Antarctica,” Meier said. “However, this might just be an extreme case of pushing the envelope of year-to-year variability. We’ll need to have several more years of data to be able to say there has been a significant change in the trend.”

Important information has emerged in the field of energy, and yet it is as if European politicians ignore it. Judge for yourself based on just the following facts (…)

Partly in response to the crazy claims of the usual global warming experts (Stevie Wonder, Beyoncé, Jennifer Lawrence, Mark Ruffalo, Bill Nye the Science Guy, Neil deGrasse Tyson, Pope Francis), I decided to write another Kindle e-book. This one is entitled, Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming.

Les gisements sont des zones généralement profondes où l’on trouve de grandes quantités de charbon. Il faut forer des puits pour y accéder et extraire le minerai. Lorsque les réserves de charbon sont relativement proches de la surface de la terre, une exploitation à ciel ouvert peut être mise en place. Il existe également des gisements de charbon sous les océans, pour le moment inexploités.

As Hurricane Maria heads north as a Cat 3 storm, much is being made of the fact that it is the strongest hurricane to hit Puerto Rico since 1928. The implication is that Maria must have been exceptionally strong.
But the reality is that Puerto Rico is little more than a speck in the vastness of the Atlantic Ocean. The odds of the eye of a major hurricane, often just 10 or 20 miles wide, making a direct hit on Puerto Rico are probably hundreds to one, given that there are thousands of miles of ocean through which hurricanes can commonly travel.

A trend toward greater discrimination under higher CO2 levels is broadly consistent with tree ring studies over the past century, with field and chamber experiments, and with geological records of C3 plants at times of altered atmospheric CO2, but increasing discrimination has not previously been included in studies of long-term atmospheric 13C/12C measurements. We further show that the inferred discrimination increase of 0.014 ± 0.007‰ ppm−1 is largely explained by photorespiratory and mesophyll effects.

Diamonds may be ‘forever’ but some may have formed more recently than geologists thought. A study of 26 diamonds, formed under extreme melting conditions in the Earth’s mantle, found two populations, one of which has geologically ‘young’ ages. The results show that certain volcanic events on Earth may still be able to create super-heated conditions previously thought to have only existed early in the planet’s history before it cooled. The findings may have implications for diamond prospecting.

With the help of satellite observations from 188 lakes worldwide, scientists have shown that the warming of large lakes amplifies their color. Lakes which are green due to their high phytoplankton content tend to become greener in warm years as phytoplankton content increases. Clear, blue lakes with little phytoplankton, on the other hand, tend to become even bluer in warm years caused by declines in phytoplankton. Thus, contrary to previous assumptions, the warming of lakes tends to amplify their richness or poverty of phytoplankton.

New England hasn’t had a major hurricane in over 60 years, but on this date in 1938, New Jersey, New York, New England and Quebec were hit by a major hurricane – which would have destroyed Lower Manhattan had it tracked 30 miles to the west

Results indicate climate models where the initiation of glaciation depends strongly on CO2concentrations over astronomical controls significantly overpredict the duration of the present-day warm period compared to past interglacial analogs.

(…) Upon our return to the Hotel after visiting the Glacier, we noticed that our brand-new photos appear to show that the Grinnell Glacier has grown slightly from the 2008 images that are displayed on the Hotel walls. There has been no reporting of this in any newspaper or broadcast that we know of. (In fact, all news coverage reports the precise opposite.) The smaller Gem Glacier—which is visible from the valley miles below—also appears to be slightly larger than it is shown in 2008 pictures on display.

It is worth re-emphasising these points:
Many storms were missed over the open ocean prior to hurricane hunter aircraft in 1944.
Even then half of the Atlantic basin was not covered.
Satellite coverage began to improve matters in 1966.
But even then monitoring has considerably improved since 1966, particularly regarding short lived storms.

Those voices are the impetus behind what Subramanian calls a “green and clean coal coalition” spanning both the developed and developing worlds. Emerging markets in Asia and Africa will continue to build new coal-fired power stations for at least the next two decades. In that timeframe, coal-fired solutions are indispensable to meeting their demands for electrification and growth. As clean coal solutions emerge, new plants in the developing world can and should be far cleaner than previous generations of coal-fired plants in Europe and America.

The study is published in the journal Nature Geoscience by a team of scientists led by Richard Millar of the University of Oxford. It has recalculated the carbon budget for limiting the Earth’s warming to 1.5 degrees Celsius above temperatures seen in the late 19th century. It had been widely assumed that this stringent target would prove unachievable, but the new study would appear to give us much more time to act if we want to stay below it.

Earth’s climate is a remarkably “noisy” system, driven by scores of oscillators, feedback mechanisms, and radiative forcings. Amidst all this noise, identifying a solitary input to the system (i.e., HGFA MAG4/6 seismic activity as a proxy for geothermal heat flux) that explains 62% of the variation in the earth’s surface temperature is a significant finding.

Que n’a-t-on pas entendu dans une partie de la presse et dans les déclarations à chaud de scientifiques et d’experts du climat sur l’uragan Irma. C’était du jamais vu, du jamais mesuré, d’une puissance inégalée, Europe 1 allant jusqu’à parler « du plus important de l’histoire climatologique ». Des eaux extraordinairement chaudes devaient expliquer son intensité effroyable (sous-entendu : Irma, c’est la faute au réchauffement), ses vents destructeurs records, son diamètre exceptionnel, ses pluies diluviennes, son raz de marée démesuré, son intensification inouïe ou ses dégâts hors normes…

Après avoir vu leur production tripler entre 2010 et 2014, les « light tight oil » américains (LTO), fréquemment appelés « pétroles de schiste », ont fait preuve d’une résilience étonnante lors de la chute des prix. Ils surprennent aujourd’hui à nouveau les marchés et pourraient contrarier la stratégie de l’OPEP.
Dans cette étude publiée par le Centre Énergie de l’Ifri, Sylvie Cornot-Gandolphe (voir le .pdf ci-dessous) présente les grands changements du secteur des LTO américains au cours des dernières années en expliquant leur résilience lors de la chute des cours et leurs perspectives de croissance.

Considering the likelihood of future presentations and discussions, an update of paleoclimatological information was overdue. I was amazed to bump into a full overview of the atmospheric CO2 content of the last 420 million years published much earlier this year. An important milestone in the history of climate on Earth

The existence of a 1500-year climatic cycle during the Holocene, related to the glacial Dansgaard-Oeschger cycle, is a matter of intense debate. However, by introducing precise timing requirements it can be shown that the 1500-year cycle displayed in Northern Hemisphere glacial records is also observed in Holocene records from all over the world.
The cycle is most prominently displayed in oceanic subsurface water temperatures, Arctic atmospheric circulation, wind deposits, Arctic drift ice, and storminess records.

Zerbini et al. also investigated/tested for the existence of an acceleration of sea level rise in each of the six Mediterranean station’s data, reporting that “our analysis indicates that it is not possible to reliably state the existence of any acceleration, in the area of this study, considering the past 140 years or so, from 1870 through 2012.”

The record-setting twelve-year long hurricane “drought” (no major hurricane landfalls on the US) was just weather. But the Left immediately boldly and confidently declared Harvey and Irma to be caused (or worsened) by anthropogenic climate change. Some of these screeds are mostly rational, just exaggerated or imbalanced.

La consommation mondiale d’énergie pourrait augmenter de 28% entre 2015 et 2040 selon les dernières prévisions de l’EIA (agence américaine d’information sur l’énergie) présentées hier. Le mix énergétique mondial devrait pour sa part rester très largement dominé par les énergies fossiles dans les décennies à venir.

This report describes this phenomenon and brings it into a modern global con- text. But the story is more than simply one of some old South American geophysical phenomenology seen from a global perspective; it is tied to an extraordinary story about new scienti c thinking, arising at the end of the 20th century, concerning the nature of change itself.
