Widener Law Professor John C. Dernbach will give an informal talk Thursday, Jan. 31 to the law school community and interested members of the public, about his role in, and the events of, the recent United Nations Climate Change Conference in Bali, Indonesia.Dernbach will speak from noon to 1 p.m. in room 204 of the main law building on the Harrisburg campus. The event is timed to coincide with the national teach-in, “Focus the Nation,” being held on Jan. 31. The event is attracting participation from millions of people at institutions nationwide and will focus on global climate change and solutions. Dernbach presented the paper “Energy Efficiency and Conservation as Ethical Responsibilities,” at the Bali conference on Dec. 14. The conference was held to negotiate an agreement on what countries should do to address climate change after 2012, when obligations under the Kyoto Protocol expire. It attracted about 10,000 environmentalists, scientists, academics and government officials from around the world.Dernbach’s teaching specialties include environmental and property law as well as international environmental law. His research concentrates on environmental law, climate change and sustainable development. Dernbach spent 2 ½ years on leave from the law school serving as director of the policy office at the Pennsylvania Department of Environmental Protection, and resumed teaching in 2006. He has written widely on environmental law and sustainable development and is the editor of Stumbling Toward Sustainability (Environmental Law Institute, July 2002), a 32-chapter book assessing U.S. efforts on sustainable development in the 10-year period since the U.N. Conference on Environment and Development in Rio De Janeiro (or Earth Summit) in 1992. The event is free and open to the public.As a lead-in to the national effort, the school’s Environmental Law and Policy Society will sponsor a web-cast of “The 2% Solution,” in A-180 on Wednesday, Jan. 30 from 7:45 to 9 p.m. The web-cast will revolve around the question: Can we as a nation get on the path to cutting global warming pollution two percent a year for the next decade? If so, what would it take?
