Hartmann reported in 2013 that humanity, as we know it, is on the verge of extinction, a warning that has largely gone unaddressed. There's a common thread to every single mass extinction in our planet's history. It's global warming.

From the Permian Mass Extinction 250 million years ago that killed off 95% of all life on Earth to the K/T mass extinction 65 million years ago that killed off the dinosaurs, all were brought about by a sudden warming of the planet. New research shows that once that warming hits a tipping point of 5-6 degrees Celsius, it triggers a cataclysmic melting of sea ice and the release of noxious methane gasses stored deep in the oceans around the world and below the permafrost in the Arctic, which further accelerates the warming of the planet to temperatures unsuitable to life.
This book, The Last Hours of Humanity, goes where far too few researchers have been willing to go, which is addressing global warming not as an economic or political problem, but as a geological problem that threatens the survival of every living thing on the planet, including us humans. By bringing together climate scientists, geologists, and cutting edge research too often left out of the global warming debate, The Last Hours of Humanity exposes the dangerous future of planet Earth, and what we humans have to do right now to save our species.
[There seems to be increased academic attention to the methane ice naturally buried in the continental shelves around the world. With increased ocean temperatures, the buried methane ice melts. Whether anything can be done is another matter.... decrease ocean temperatures...?]
