With tipping points and extreme global warming looming, the key to understanding our climate future lies in our distant past With rising emissions, we are on track to cause rapid global warming with devastating con- sequences. But how bad could climate change get and what might it do to planet Earth and humanity?Runaway Climate explores the causes of the Paleocene Eocene Thermal Maximum (PETM) rapid climate-heating episode, its dramatic impact on life on Earth, and lessons for our climate future.Fifty-six million years ago our planet experienced a period of intense warming known as the PETM, resulting in a rapid global temperature increase of about 7C. Triggered by natural geological processes over millennia and magnified by strong climate feedback loops, the PETM lasted for about 180,000 years and drastically altered life on Earth. Yet in only a few short decades we''ve pumped similar amounts of greenhouse gasses into the atmosphere, m
