SEASON PREMIERE: It’s about time. Bill Maher is back for a new season, just as President Obama is jockeying for approval of his plan to punish Syria for using chemical weapons, Colorado is awash with what headlines are calling “biblical rainfall,” and Miley Cyrus has managed to spark media outrage on two different occasions within a single week. Welcome back, Bill. Have a great time. And viewers should, too, since tonight’s scheduled guests include the always quotable journalist and author Matt Taibbi (once a Real Time correspondent) and – as perhaps the perfect guy to talk about climate change – Bill Nye, known to a generation of TV viewers as Bill Nye the Science Guy.
