Betsy's favorite climate activists grace this edition of The Green Front.

Up first is Dr. Peter Joseph of The Climate Project, just back from the DC tar sands protest.  He'll share his interpretations of the current temperature of climate politics as well as what's at stake for President Obama on tar sands decision. Then, Alec Loorz of Kids vs. Global Warming and the iMatter march, checks in from the road.  And last, but not least, "oar" own Roz Savage - fresh from her Indian Ocean crossing - on what's next for the solo rower for climate change awareness!
