A lecture by Dr. Tom Sever of NASA on how the Maya may have affected their own regional climate leading to drought.

Climate Change and Violence? Cautionary Tales from the Pre-Columbian Andes The seminar will take place on January 25, 2008, 4 to 5 PM, in 201 Old Chem Building, West Campus, Duke University, Durham, North Carolina. Dr. Arkush received her PhD at UCLA in 2005. Her research centers on the interplay of warfare, political power, social identity, and ritual in the prehispanic Andes. Her doctoral research focused on the later part of the prehispanic sequence after about A.D. 1000, when many small polities throughout the Andes were apparently engaged in cycles of endemic warfare. Fieldwork on a suite of fortified hilltop sites in the northern Lake Titicaca basin in Peru investigated the regional patterns that emerged from conflictual and cooperative social relationships. This study also examined the chronology of fortification to question current interpretations of the causes of intergroup violence at the time.

Professor Andrew Frank of the University of California, Davis is the godfather of plug-in hybrids. He and his students have been building them for more than a decade, showing us what the car companies could be doing, if only they would. Hear his take on the state of the industry in an interview at EVS23, the international electric vehicle symposium in Anaheim, Calif. in December 2007.

Activism has always been an important tool for Plug In America. Besides our inside work in government and industry, we hit the streets when a good protest or demonstration would be the most effective move. Zan Dubin Scott talks about some of our best actions, and why they worked.
