I'm excited to announce my Point of Inquiry guest, for the program airing on Friday, June 18: Bill McKibben. He is author of many great books including, most recently, Eaarth: Making Life on a Tough New Planet--which is prompting a ton of discussion right now about the new world we're going to have to inhabit for the rest of our lives (and indeed, for many generations) because of anthropogenic climate change. Although I've failed to do so for the last two shows, I'm announcing this interview in plenty of time to take questions for McKibben from POI listeners. I will be interviewing Bill on Monday afternoon, the 14th, so that leaves three full days for thinking about questions you might like to hear him address on the air. So leave your questions for Bill McKibben below, or, head over to the Point of Inquiry forums and leave them there. Either way, I'll be reading some off on the air...
