On Tuesday's Riz Khan show we ask: Can people power turn the tide on climate change before it is too late?
Pablo Solon, Bolivia's ambassador to the UN, and Rob Bradley, the director of climate policy at the World Research Institute join the show.
You can join the conversation. Call in with your questions and comments on Tuesday, April 20, 2010 at our new live time of 1630GMT, with repeats at 2130GMT and the next day at 0230GMT and 1130GMT.
