Natural Archives, Changing Climates

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 18 July 2005.

Free AGCI Walter Orr Roberts Public Lecture: December 2

Free AGCI Walter Orr Roberts Public Lecture: December 2

Join us to hear Prof. Palma-Oliveira, of the University of Lisbon, discuss "Predicting Community Resilience in a Changing Climate." Prof. Palma-Oliveira studies the radical changes that have occurred in human societies and ecosystems around the globe since the rise of agriculture around 6000 BCE. Research now illustrates that these shifts in human societies, coupled with the consequences of climate change, comprise a major threat to communities across the globe. Community resilience depends upon two main factors: the degree to which (a) local ecosystem functions are dependent on the human actions and (b) social stress and inequality abound within a society. This lecture explores how a better understanding of these two factors allows communities to better predict and shape their resilience in the face of global change.
