From the New World Notes blog:

The human species is doomed, and we'll be gone by 2050, says scientist and ecology professor Guy McPherson. Irreversible, rapidly escalating climate change--caused by our hydrocarbon emissions and their aftereffects--will destroy our habitat sooner than most people expect. And no captain of industry, university president, or politician would risk damaging his or her career to save the species.
Part One: What to do? That's next week's installment. This week McPherson focuses on how serious the climate change situation already is--and how deeply mired in denial are all the leaders and all the institutions of the "civilization" that is responsible for the calamity.
Guy McPherson is Professor Emeritus of Natural Resources and Ecology & Evolutionary Biology at the University of Arizona.
