When China halted plans for more than 100 new coal-fired power plants this year, even as President Trump vowed to “bring back coal” in America, the contrast seemed to confirm Beijing’s new role as a leader in the fight against climate change.
But new data on the world’s biggest developers of coal-fired power plants paints a very different picture: China’s energy companies will make up nearly half of the new coal generation expected to go online in the next decade.
These Chinese corporations are building or planning to build more than 700 new coal plants at home and around the world (…)

During the first 6 months of 2017, 285 scientific papers have already been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media.
These 285 new papers support the position that there are significant limitations and uncertainties inherent in our understanding of climate and climate changes. Climate science is not settled.

Les hommes politiques, à l’image de Barack Obama avancent que 97% des scientifiques sont d’accord sur les causes humaines et les dangers du réchauffement climatique. Des chercheurs ont étudié l’ensemble des 11 944 publications sur le climat parues entre 1991 et 2011. Les résultats publiés en 2013 montrent que près de 66% des publications n’expriment pas d’avis, ni positif, ni négatif sur le réchauffement climatique.

In a new study, scientists puzzled by the sudden ice loss matched satellite images of Antarctica with weather data from the second half of 2016 to figure out what caused so much of the ice to melt. They found that a series of remarkable storms during September, October and November brought warm air and strong winds from the north that melted 75,000 square kilometers (30,000 square miles) of ice per day. That’s like losing a South Carolina-sized chunk of ice every 24 hours.

The model has been updated in 2014 to better account for meltwater refreezing in the snow, and again in 2015 to account for the lower reflectivity of sunlight in bare ice than in snow. Finally, it has been updated again in 2017 with a more advanced representation of percolation and refreezing of meltwater. At the same time, we have extended the reference period to 1981-2010. The update means that the new maps, values and curves will deviate from the previous ones. Everything shown on this site, however, is calculated with this new model, so that all curves and values are comparable.

… dont août 1911 l’un des mois les plus chauds de l’histoire et 1947 (40°C à Paris les 27 et 28 juillet, record absolu depuis 1873). Emmanuel Leroy Ladurie indique qu’au dix-huitième siècle siècle les canicules pouvaient se répéter plusieurs étés consécutifs : ainsi les années 1705, 1706 et 1707, et le « couple brûlant » (sic) des années 1718 et 1719 « avec sauterelles africaines jusqu’au Languedoc ».
