The Earth is running a fever. The on-going 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, and the melting ice sheets are causing sea levels to rise around the globe. In this talk, I will review evidence for climate change, natural and human-caused, 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.
