Just what I suspected, more research shows that humans are re-creating the great Permian Extinction.

If we continue to avoid taking action against oil and coal pollution we will kill off most of life on earth. We've known that since the 70's but vast amounts of research, not wild speculation, is narrowing the focus.

California is moving toward a more sustainable environment as fast our our right-wing Republican anchors can drag behind us :-) (I voted for Arnold Schwarzenegger only because he really worked at moving California forward on this issue.)

"The surprise to Dr. Clapham was how closely the findings from the Great Dying matched today’s trends in ocean chemistry. High concentrations of carbon-based gases in the atmosphere are leading to warming, rapid acidification and low-oxygen dead zones in the oceans."

PS: This is just more research with the same conclusion, not anything wildly new. Nice new approach though.

Humans are pumping the Carboniferous period of geologic history, the time when huge amounts of carbon were sucked out of the atmosphere and oceans to create coal and oil, back into the air and oceans. This happened before - on a smaller scale!

A hundred million years after the Carboniferous huge lava flows in what is now Siberia burned through coal seams and put too much carbon back in the atmosphere and oceans. That killed about 95% of life. That was the end of the huge explosion of life in the Permian period.
