CAMEL (http://www.camelclimatechange.org/) is a free, comprehensive, interdisciplinary, multimedia resource for educator on all issues surrounding climate change. The site includes numerous assignments, images, syllabi (none on ethics!), case studies, PowerPoint presentations, white papers, and audio- and videocasts from leading educators on climate change.
It also hosts a weekly live webinar series. Of interest to many will be its sessions on geoengineering. The next geoengineering session will be on Tuesday, November 20 at 3:00 Eastern Time, and is being led by Wil Burns (Associate Director and Master of Science, Energy Policy & Climate Program Johns Hopkins University).
