Most scientists agree that the Earth is undergoing significant climate change, partly due to the greenhouse gases produced when fossil fuels like oil, gas and coal are burned.
However, earth scientists know that the planetary environment has always been in flux. Some of those changes have caused extinctions on a massive scale. However, for humans, higher apes and other large mammals, environmental fluctuations have sometimes been a goad to adaptation.
Geologists and climatologists, who specialize in the physical earth sciences, came together with biologists, paleontologists and anthropologists, who mainly concern themselves with life on Earth, for a symposium at Columbia University’s Lamont-Doherty Earth Observatory, to discuss the question, “Did Climate Change Shape Human Evolution?”
