Extreme global warming 252 million years ago caused a severe mass extinction of life on Earth. It took life up to 9 million years to recover. New study finds clues in the Arctic as to why this recovery took so long. 96 percent of marine species, and 70 percent of terrestrial life died off in the Permian-Triassic extinction event, as geologists know it. It is also known as The Great Dying Event for obvious reasons. [Yet our present political goal is to heat up the planet even further and quicker. Not to "go political," but check Jill Stein's website and listen to what she's saying.]
