Beri Bonglim of the Global Crop Diversity Trust has been working with a team of seed collectors trying to rescue the genetic diversity of edible plants- can they help us survive global warming?.. Dr David Reichmuth from the Clean Vehicles Project has been crunching the numbers on the carbon impact of electric cars- he joins Thom with the details... And Dr Andrew Glikson from the Australian National University compares our current situation to mass extinctions in Earth's history- what is likely to happen if we keep pouring carbon into the atmosphere?.. Plus- Greg Palast on the deep water blowout in the Caspian BP doesn't want anyone to know about.
