Dr. Lisa Heinzerling of Georgetown University and the EPA will be on campus onThursday, April 12th, to give a talk on "Climate Change and the EPA" for the Purdue Lectures in Ethics, Policy, and Science at 5:30 PM in PFEN 241. Dr. Heinzerling is one of the lead attorneys on the lawsuit that forced EPA to regulate greenhouse gases under the Clean Air Act (Mass et al. vs. EPA). So she is a very knowledgeable and important person on climate policy these days - I would strongly encourage you to attend this session if you are interested in US climate policy.
