The Appalachian Basin is driving growth of record-shattering U.S. natural gas production, which in turn has helped spur more than $25 billion in natural gas electricity generation investment in the region. In fact, there are 29 new 475-megawatt (MW) or greater natural gas-fired power plants that are in various stages of permitting, under construction or have recently become operational in Ohio (10), Pennsylvania (16) and West Virginia (3), representing more than 26,000 MW of added electric capacity, more than 17,000 jobs during construction and incredible emissions reductions in the electricity sector.

Trois jours après la clôture de la COP24, l’Agence internationale de l’énergie (AIE) a publié le 18 décembre son rapport annuel consacré au charbon. Elle y souligne le rôle central de cette énergie au niveau mondial et estime que sa consommation globale devrait rester stable dans les 5 prochaines années. Explications.
La consommation de charbon encore appelée à augmenter en Inde et en Asie du Sud-Est
Après deux années de baisse, la consommation mondiale de charbon a augmenté de près de 1% en 2017 et cette hausse devrait se poursuivre en 2018 selon les dernières estimations de l’AIE. Principalement consommé à des fins de production électrique(1), le charbon a encore compté pour 38% de la production mondiale d’électricité en 2017.
Dans son rapport Coal 2018, l’AIE estime que la consommation mondiale de charbon pourrait rester stable d’ici à 2023 : la baisse de la demande envisagée en Europe et en Amérique du Nord serait plus que compensée par une forte croissance de la consommation en Inde et en Asie du Sud-Est selon les prévisions de l’Agence.

Study suggests that in the last 60 years up to half the observed warming and associated sea level rise in low- and mid- latitudes of the Atlantic Ocean is due to changes in ocean circulation.
Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system. More than 90% of this excess energy has been absorbed by the ocean, leading to increased ocean temperatures and associated sea level rise, while moderating surface warming.
The multi-disciplinary team of scientists have published estimates in PNAS, that global warming of the oceans of 436 x 1021 Joules has occurred from 1871 to present (roughly 1000 times annual worldwide human primary energy consumption) and that comparable warming happened over the periods 1920-1945 and 1990-2015.

NBC News’ Chuck Todd recently asserted that we humans can control the climate and the frequency or intensity of extreme weather events (hurricanes, floods, droughts) and disasters (wildfires) with our CO2 emissions. He has declared the science is “settled” on this point and therefore no “denier” is allowed on his Meet the Press program. But Todd and the members of his panel have recited claims that are contravened by observational evidence and scientific publications.
