Why Are Fossils Important?

Fossils are clues from earth history that tell us what happens when climates change. What's happening now though, is happening so fast, it's really out of scale with any clime mate change in earth history. But we can look to the fossil record and see what lives, what dies,. When temperatures rise, what sort of things might help you to survive? Hopefully that can help us ameliorate what’s going on today.
