I found this link at Andrew C. Revkin's New York Times blog.
"A recipient of the 1976 Nobel Prize in physics, Richter was a signatory on a letter from 34 Nobel laureates to Obama last year pushing for a big and sustained rise in the federal investment in energy research. (He told me he is unaware of any response from the White House.) He also has written “Beyond Smoke and Mirrors,” a cogent road map for facing the daunting long-term challenge of cutting emissions of greenhouse gases even as humanity’s growth spurt crests in the next few decades."It's well worth listeing too.
