The extraordinary sight was witnessed by tourists on an Arctic cruise aboard the Finnish-built MV Akademik Shokalskiy.
A source at Wrangel Island Nature Reserve said: “There were at least 230 polar bears, including single males, single females, mothers with cubs and even two mothers with four cubs each.”
Experts called the sight of so many polar bears together “unique”. The huge number could in fact amount to as much one per cent of the entire world’s population of the creatures.
(…) We are left with conjectures and other speculation, both in the recent past and for the future. For this, climatologists develop models with which they can test their hypotheses. But these models are obviously overheating. (…)
Global methane emissions from agriculture are larger than estimated due to the previous use of out-of-date data on carbon emissions generated by livestock, according to a study published in the open access journal Carbon Balance and Management.
In the last 4 months, 40 more graphs taken from 30 more new peer-reviewed scientific papers have made their way into the ever-growing volume of evidence that today’s climate is not only not unprecedented or unusual in the context of the last millennium, but modern temperature values are still among the coldest of the last 10,000 years.
Overall, initial figures suggest that Greenland may have gained a small amount of ice over the 2016-17 year. If confirmed, this would mark a one-year blip in the long-term trend of year-on-year declines over recent decades.
Recent findings suggest that episodes of very rapid sea-level rise of about 20m in less than 500 years occurred in the last deglaciation, caused by periods of catastrophic ice-sheet collapse as the Earth warmed after the last ice age about 20,000 years ago.
Lead author, PhD candidate at the University of Sydney, Kelsey Sanborn, has shown this sea-level rise event was associated with “drowning” or death of coral reefs in Hawaii.

Ninety years ago brought the worst floods in US history. The Mississippi River was flooded for more than six months, forcing hundreds of thousands of people to abandon their homes permanently. Vermont’s worst flood on record occurred in November, 1927. The Red Cross described 1927 as the worst year in history.
Expedition co-chief scientist Rupert Sutherland of Victoria University of Wellington in New Zealand said researchers had believed that Zealandia was submerged when it separated from Australia and Antarctica about 80 million years ago.
Big geographic changes across northern Zealandia, which is about the same size as India, have implications for understanding questions such as how plants and animals dispersed and evolved in the South Pacific.
A number of authors, including the IPCC, have argued that climate models have systematically overstated the rate of global warming in recent decades. A recent paper by Millar et al. (2017) presented the same finding in a diagram of temperature change versus cumulative carbon emissions since 1870.
In the climate debate, though, it pays to read the small print. Official climatology does not usually admit its many errors: instead, we are ordered to obey the “consensus”, as the Party Line is these days rebranded. On reading the headlines, I suspected at once that the true purpose of the latest admission, by Millar et al. in the current issue of Nature Geo“science”, is to minimize and thus to conceal the true magnitude of past over-predictions.
The most productive volcanic systems on Earth are hidden under an average of 8,500 feet (2,600 m) of water. Beneath the oceans a global system of mid-ocean ridges produces an estimated 75% of the annual output of magma. An estimated 0.7 cubic miles (3 cubic kilometers) of lava is erupted. The magma and lava create the edges of new oceanic plates and supply heat and chemicals to some of the Earth’s most unusual and rare ecosystems.
Les énergies fossiles toujours omniprésentes dans le mix mondial
La consommation mondiale d’énergie primaire a encore reposé à 81,4% sur les énergies fossiles en 2015 selon les dernières données de l’AIE. En 1973, cette part atteignait 86,7% (dont 46,2% pour le seul pétrole) et les énergies décarbonées ont ainsi légèrement progressé dans le mix énergétique mondial.
Notons que les productions mondiales de gaz naturel et de charbon ont respectivement triplé et plus que doublé depuis 1973. Les émissions mondiales de CO2 relatives à la combustion d’énergie ont pour leur part doublé durant cette période.
Solar activity during the current sunspot minimum has fallen to levels unknown since the start of the 20th century. The Maunder minimum (about 1650–1700) was a prolonged episode of low solar activity which coincided with more severe winters in the United Kingdom and continental Europe. Motivated by recent relatively cold winters in the UK, we investigate the possible connection with solar activity. We identify regionally anomalous cold winters by detrending the Central England temperature (CET) record using reconstructions of the northern hemisphere mean temperature.
L’incroyable nouvelle a été annoncée par Mathieu Vidard dans l’émission La Tête au carrésur France Inter, le 20 septembre 2017 (ici, très brièvement, à partir de 10’, il faut bien viser) :
Maintenir le réchauffement climatique en dessous de 1,5°C, c’est encore possible, c’est l’objectif qui avait été fixé par les Accords de Paris à l’issue de la COP 21. La bonne nouvelle vient d’une équipe de recherche internationale. D’après leurs analyses, l’ampleur du réchauffement climatique qui a déjà eu lieu a été surestimée et la quantité de carbone que l’humanité peut émettre à partir de 2015 en restant en-dessous de ce seuil de 1,5°C serait trois fois supérieure à ce qui avait été annoncé.
Significant and fast reductions in sea level unload the lithosphere, which can increase the production and eruption of magma. Here we calculate variations in surface load associated with the Messinian salinity crisis and compile the available time constraints for pan-Mediterranean magmatism.
Energy researchers at IHS Markit have completed the first, three-year phase of a massive Permian Basin research project that models and interprets the giant basin’s key geologic characteristics to better estimate its remaining hydrocarbon potential, and initial results indicate the giant basin still holds an estimated 60 billion to 70 billion barrels of technically recoverable resources.
To conduct this new analysis, researchers used the IHS Markit historical well and production database that includes more than 440,000 Permian Basin wells, and a new proprietary software tool that, for the first time, enables them to leverage interpreted formation ‘tops’ data to identify accurate formations for completion intervals on hundreds of thousands of wells
“Les faits, et seulement les faits” doivent nous éclairer et nous préserver de malentendus entourant toute discussion, alors que l’administration Trump a pris la décision de se retirer de l’Accord de Paris COP21 (2015) qui traite du changement climatique.
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.
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.
“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.
