The 40th anniversary of Earth Day fast approaches—and what better time to take stock of how we’re doing on climate change? This GRITtv segment serves as a great summary of the current climate scene: Watch Mother Jones contributor Mark Hertsgaard and the NRDC’s Katherine Kennedy discuss whether cap and trade can work, how to kick our coal habit, and the current climate bill. (And if you’re curious about what environmentalists are up against, I strongly reccomend you check out the Sen. James Inhofe clip at 09:03. Wow.)
