David Suzuki: Des solutions pour rafraîchir signifient qu'une planète plus chaude est inévitable 22 août 2018

The study, Trajectories of the Earth System in the Anthropocene, confirms global warming has accelerated during the current epoch, when humans have become a driving force in geophysical changes to Earth: “The Anthropocene represents the beginning of a very rapid human-driven trajectory of the Earth System away from the glacial–interglacial limit cycle toward new, hotter climatic conditions and a profoundly different biosphere.”

The most troubling part of the research, published in Proceedings of the National Academy of Sciences, is its prediction that, beyond a 2-degree C rise in global temperature above preindustrial levels, “intrinsic biogeophysical feedbacks in the Earth System” will kick in, accelerating warming and its consequences at an even greater rate than we’re currently experiencing.
