COP21 ou l’hypocrisie de l’industrie

by Prof. Dr. Istvan Marko, 31 octobre 2015,  in FoS

Si vous pensez que la conférence sur le climat qui se tiendra à Paris en décembre 2015 (COP21) a quelque chose à voir avec le climat ou la protection de la nature, révisez votre copie. Vous avez tout faux. Les premiers qui s’en rendront compte, après avoir vainement fouillé dans les derniers recoins de ces futurs accords, minimalistes et non-contraignants mais présentés par les politiques comme une grandiose réussite pour l’environnement et le climat, seront les écolos et certaines ONG environnementales.

The Impact of Elevated CO2 on a Widespread Ectomycorrhizal Fungi

by McCormack et al., 2017, September 18, 2017 in FungalEcology

In light of the above findings, it would appear that, given the near-global distribution of this EM fungi and its importance in stimulating ecosystem productivity, the positive impact of elevated CO2 on C. geophilumproduction (~50% increase for a 200 ppm rise) represents a welcomed benefit for the future of Earth’s forests.

Sea Ice Extent Sinks to Record Lows at Both Poles

by Maria-José Vinas, August 4, 2017 in

“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.”

Inevitable Disaster: Why Hurricanes Can’t Be Blamed On Global Warming

by Roy W. Spencer, September18, 2017, in GlobalWarming

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.

Techniques d’exploitation des mines de charbon

by Connaissance des Energies, 16 mars 2015

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.

Puerto Rico’s Hurricane History

by P.  Homewood, September 22, 2017 in NotaLotofPeopleKnowThat

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.

Study: plants are globally getting more efficient thanks to rising carbon dioxide

by University of California, September 12, 2017 in WUWT

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 show Earth still capable of ‘superhot’ surprises

by Europlanet Media Centre, September 21, 2017 in ScienceDaily

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.

In times of climate change: What a lake’s color can tell about its condition

by Forschungsverbund Berlin e.V. (FVB), September 21, in ScienceDaily

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.

Are the glaciers in Glacier National Park growing? Lysander Spooner University investigates climate claims

by Lysander Spooner University, September 2017

(…) 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.
