I've read a few books on the matter, but now that I've gone back and looked the only one I still have on me is "A Short History of Nearly Everything" by Bill Bryson. I've read several articles but I don't keep track of them. However no one could really be sure what could happen there are way too many factors, Earth's "wobbles", Messinian Salinity Crisis, and so many other factors we haven't even discovered. The point is e jsut don't know and can't know so we need to stop playing with it and conserve.
