Determining what killed the dinosaurs 66 million years ago at the end of the Cretaceous Period has long been a source of discussion, as scientists try to figure out what caused the five big extinction events that changed life on Earth in a geological second.
a recent study on climate modeling provides an unsettling look into the future of virtually every species on the planet. Over the course of the last half a billion years or thereabouts, there have likely been multiple big extinction events that have affected life on Earth.
Scientists have discovered evidence pointing to a substantial link in geologic time between the size of mass extinctions and global temperature fluctuations.
