From the page: "Ohio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. "The study suggests that upheavals in the earth's crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world's oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere."

- Perhaps the fascinating thing about is the speed in which the climate has changed dramatically from an environment that could support live as we know it today to one where it would not. It seems like a fragile system.
