New Study: What’s Scarier than the Permian Extinction? Burn All the Fossil Fuels to Find Out.

Conservatives are suicidal.
If we burn all the fossil fuels “not only will the resultant climate change be faster than anything Earth has seen for millions of years, the climate that will exist is likely to have no natural counterpart, as far as we can tell, in at least the last 420 million years.” — Gavin Foster, Professor of Isotope Geochemistry at the University of Southampton

Back in the 1780s as coal-fired smoke stacks sprouted across England to belch their black soot into the hitherto virgin skies of Earth, it’s likely we had not an inkling of the destruction they were ultimately capable of unleashing:
Svante Arrhenius, by the late 19th Century, had hinted that coal burning might warm the Earth by a tiny bit in a few thousand years. But the very fossils we were digging up and burning at an ever-more-rapid pace warned of a different and far more ominous story (see video above). They hinted of a time when massive volumes of ancient carbon stored in the Earth were released into the atmosphere over the course of thousands of years. And that this release created such hot and toxic conditions that, for most living things, the Earth was no longer habitable.
Unsafe Warming
The Permian-Triassic Extinction of 252 million years ago was the worst hothouse catastrophe that has ever occurred in all of the geological record. It wiped out 96 percent of marine species and more than 70 percent of terrestrial vertebrates. It was the worst of many such hothouse events sparked by rising levels of greenhouse gasses that now serve as a clear warning in the fossil record of the dangers we invite.
