Offers an overview of the contributions geology has made to the study of climate change and the nuanced picture it presents of a climate that has gone through constant change over the course of millennia.

"Man-made climate change may have began in the last two hundred years, but humankind has witnessed many eras of climate instability. The results have not always been pretty: once-mighty civilizations felled by pestilence and glacial melt and drought. But we have one powerful advantage as we face our current crisis: history. The study of ancient climates has advanced tremendously in the past ten years, to the point where we can now reconstruct seasonal...

Whether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution's Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present...
