Last Hours

 

    Each of the five mass extinction events on Earth were ultimately driven by global warming. Could we be looking at another mass extinction if we don’t soon change our ways?

   AN EBOOK BY THOM HARTMANN

Humanity, as we know it, could be on the verge of extinction.
There’s a common thread to every mass extinction in our planet’s deep geologic 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 that may be as low as 5-6 degrees Celsius, it triggers a cataclysmic melting of sea ice and the release of methane gas stored deep in the oceans around the world and below the permafrost in the Arctic.  Methane is a far more potent greenhouse gas than carbon dioxide, so these releases further accelerate the warming of the planet to temperatures unsuitable to life.
Unlike during past extinctions, which usually took tens of thousands of years to warm the planet to a critical tipping point, humans today, through our addiction to ancient sunlight in the form of carbon-based fossil fuels, could accomplish this horrific feat in just a few centuries.
The Last Hours of Humanity ebook by Thom Hartmann, goes where far too few researchers have, addressing global warming not just as an economic or political problem, but as a geological problem that threatens the survival of virtually 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 a possible dangerous future for planet Earth, and what we humans must do right now to save our planet and our species.
