Talk/Lecture: Geoengineering: Time for Some Gentle Experimentation
13.12.2012, Washington, DC
„Join RFF for a special event with Thomas C. Schelling,[nbsp]2005 Nobel Laureate in Economic Sciences, as part of RFF’s 60th anniversary celebration: Resources 2020, a yearlong exploration of how economic inquiry can address future environmental and natural resource challenges.“
Project ongoing: Reviewing the potential impacts of geoengineering on ecosystems and biodiversity
Project by University of Cambridge and UNEP / WCMC. „Work on this review is ongoing, and it will provide a very useful reference guide for those seeking to research or respond to developments in geoengineering. It will also help people to access the latest information on twenty of the geoengineering techniques currently being discussed and their potential positive or negative impacts on biodiversity.“
