At a recent House Science Committee hearing, climate scientist Ben Santer had the opportunity to address Pat Michaels' misinformation head on. Peter Sinclair, who hosts videos on the excellent site Climate Denial Crock of the Week, posted a video of their exchange.
Video of the entire hearing is available from C-SPAN here.
