Related: About this forumWhat Could Be Worse Than The Permian Extinction? Let's Burn ALL Fossil Fuels And Find Out!
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 SouthamptonBack in the 1780s as coal-fired smoke stacks sprouted across England to belch their black soot into the hitherto virgin skies of Earth, its likely we had not an inkling of the destruction they were ultimately capable of unleashing:
(Scientists have now found that burning all the fossil fuels through about 2250 could result in conditions that are worse than those that occurred during the Permian Extinction of 252 million years ago. Video source: Catastrophe The Permian Extinction.)
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.
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.
Today, after merely 230-odd years and following the emission, by fossil fuel burning, of hundreds of billions of tons of carbon into the atmosphere, the Earth has warmed by far more than just a tiny bit. The glaciers are melting, the seas are rising, the corals are bleaching from the heat of it all, and unprecedented (to modern humans) droughts, heatwaves, storms and wildfires are all being unleashed.

(Unsafe at any warming. As of 2014 the world was about 0.8 C hotter than NASAs 20th Century baseline which was already hotter than any previous time period in which human civilization existed. By 2016, that line had moved up to 0.98 C hotter than the NASA 20th Century range and 1.2 C hotter than 1880s averages. Image source: Precarious Climate.)
