The Climate Crisis: Where Are We, What Can We Do?
Paleoclimatologist Dr. Maureen Raymo

The Earth is running a fever. The ongoing pollution of our atmosphere with an invisible odorless gas called carbon dioxide, is trapping heat at the Earth’s surface and causing temperatures to rise on land and in the ocean. The polar regions are warming fastest of all as reflective snow and ice is replaced by darker, more heat-absorbing land and sea. The melting ice sheets are causing sea levels to rise around the globe. In this talk, Dr. Raymo will review evidence for climate change, natural and manmade, and explore how ice sheets and sea level changed in the past. How fast climate changes in the future will depend on our collective actions as individuals, families, communities, and governments.
