Scientists say, New York Post  the concentration of carbon dioxide is rising faster than at any time since the age of the dinosaurs.

And our planet is just 140 years away from a climate change event similar to one that triggered mass extinctions, according to the research.

It could lead to species being wiped out on a massive scale in fewer than five generations.

Lead author Professor Philip Gingerich, of the University of Michigan, said: “You and I won’t be here in 2159, but that’s only about four generations away.

“When you start to think about your children and your grandchildren and your great-grandchildren, you are about there.”

The study, published in the journal Paleoceanography and Paleoclimatology, found humans are pumping CO2 into the air at a rate ten times higher than 56 million years ago.

That sparked an event known as the Paleocene-Eocene Thermal Maximum (PETM) when temperatures rose by five to eight degrees Celsius (9 to 14 degrees Fahrenheit).

It killed off both land and sea animals — and took more than 150,000 years for the planet to return to normal. This has been used as a benchmark for modern climate change in the past. But the latest finding shows we are on track to meet it much sooner than feared.

The pace of today’s warming far outstrips any climate event that has happened since the extinction of the dinosaurs.

Professor Gabriel Bowen, a geophysicist at the University of Utah who reviewed the research for the journal, said: “Given a business-as-usual assumption for the future, the rates of carbon release that are happening today are really unprecedented, even in the context of an event like the PETM…….. https://nypost.com/2019/02/21/earth-facing-global-warming-armageddon-in-less-than-150-years/
