San Diego U-T letter to the editor: Energy and security

"Most impressive is the work of Citizens Climate Lobby, a relatively new, fastgrowing, nonpartisan, nonprofit group with 91 chapters across the United States and Canada. If you want to join the fight to save the planet, to save creation for your grandchildren, there is no more effective step you could take than becoming an active member of this group."

- Dr. James Hansen, head of Goddard Institute for Space Studies, NASA
