David Gerard, chair of Lawrence University’s Department of Economics, will give a talk titled “The Answer Is a Carbon Tax: What’s the Question?” at the April 1 meeting of the Climate Change Coalition of Door County. The talk, at Bjorklunden, 7590 Boynton Lane, Baileys Harbor, begins at 7 pm. It is free, and the public is welcome.

In his talk, Dr. Gerard will review the considerable consensus about climate policy that the economics profession has reached. He will outline projected impacts of fossil fuel emissions on global temperatures and discuss the economic and political challenges associated with mitigating carbon emissions, drawing in part on his research in electricity generation costs and “clean coal” technologies. He will also present some basic tradeoffs between mitigation, adaptation and economic growth.
