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.

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

We describe late Miocene tetrapod footprints (tracks) from the Trachilos locality in western Crete (Greece), which show hominin-like characteristics. They occur in an emergent horizon within an otherwise marginal marine succession of Messinian age (latest Miocene), dated to approximately 5.7 Ma (million years), just prior to the Messinian Salinity Crisis.

Dans la lutte que mènent nos villes contre la pollution urbaine, on perçoit la recherche désespérée de solutions alternatives aux véhicules conventionnels. C’est le cas en particulier pour les particules fines, même s’il est de bon ton de passer sous silence que le chauffage contribue aussi largement à cette pollution….

Greenland’s melt season ended a month ago, and since last September the ice sheet has grown at close to record rate.

Currently (as of year 2007), human population on earth is 6.6 billion (via wikipedia). I went around to look for how much CO2 is exhaled out per person, and 2 claims were found (both via wikipedia)

Between 2007 and 2015 total annual US CO2 emissions decreased by 740 million tons (12%). An updated analysis shows that 35% of this decrease was caused by natural gas replacing coal in electricity generation, 30% by lower fuel consumption in the transportation sector, 28% by renewables replacing

What is causing the death of the polar bear as a climate change icon? Fat bears are part of it, but mostly it’s the fact that polar bear numbers haven’t declined as predicted.

Earlier this year, DEFRA published a report by the Air Quality Expert Group into the impacts of biomass on air quality. The results make for startling reading.
Among the findings are: (…) (…)

If “the supervolcano threat is substantially greater than the asteroid or comet threat,” does this mean we can stop fretting about Gorebal Warming and the Sixth Mass Extinction? Is NASA really moving on to actual threats to the planet? Well, not threats to the planet… The planet has handled supervolcanoes, asteroids and comets quite well over its 4.5 billion year lifespan.

While we obsess about climate change and debate if we live in the Anthropocene, we prepare poorly or not at all for natural forces like volcanoes that can level cities. This is folly we can no longer afford. Experts recommend a simple first step to better protect ourselves. Let’s start listening, or nature will teach us an expensive lesson.
California is the State most at risk due to its volcanoes near major cities, as shown in this map from the website of the California Volcano Observatory

Here’s a good example of how climate alarmists and leftists in Germany react when confronted with different opinions or the truth. It just illustrates the brand of radicalism we’re up against.

Specifically the Bureau of Land Management Health Risk Evaluation for Cabon Dioxyde points out:
A value of 40,000 ppm is considered immediately dangerous to life and health based on the fact that a 30-minute exposure to 50,000 ppm produces intoxication, and concentrations greater than that (7-10%) produce unconsciousness (NIOSH 1996; Tox. Review 2005). Additionally, acute toxicity data show the lethal concentration low (LCLo) for CO2 is 90,000 ppm (9%) over 5 minutes (NIOSH 1996).
