Last Hours of Humanity: Warming the World to Extinction

Last Hours of Humanity: Warming the World to Extinction
"If you were standing outdoors looking at the distant and reddening sky 250 million years ago as the Permian Mass Extinction was beginning, unless you were in the region that is known as Siberia you would have no idea that a tipping point had just been passed and soon 95% of all life on earth would be dead.
It's almost impossible to identify tipping points, except in retrospect."
