How can we better understand the future climate by investigating the past? As Ray Bradley explains, proxy records--things like tree rings, ice-cores, and sediment cores--offer an invaluable window into the past climate changes and their causes. Using this historical perspective, scientists can more accurately predict future climate change. In this talk, Bradley presents the careful detective work of paleoclimatologists and the implications of their findings for modern-day climate forecasting. Recorded
