What if efforts to negotiate meaningful limits on global greenhouse gas emissions fail and global climate change seems likely to run out of control? Some scientists and policymakers are beginning to talk seriously about geoengineering options. But geoengineering – the deliberate modification of earth systems to affect weather and climate – carries hazards of its own.
University of Iowa Professor of Law John Carlson will discuss the challenges to international law posed by geoengineering in a UI Explorers Lecture sponsored by the UI Museum of Natural History. The free public lecture will be at 7 p.m. Thursday, Jan. 20, in the Biosphere Discovery Hub of MacBride Hall.
Carlson’s research focuses on issues of international law and governance, especially with respect to global environmental problems, including climate change. Since 2008, he has served as senior associate to UI President Sally Mason. He is currently chair of the UI Sustainability Steering Group and has previously served as president of the Faculty Senate and as a member of the advisory board of the Center for Global and Regional Environmental Research.
