In a series of votes this past week, the U.S. Senate rejected a proposal by Senators John McCain and Joe Lieberman which would have capped greenhouse gas emissions. Instead, in what some see as a major turnaround, they passed a non-binding resolution saying that global warming is real, harmful, and largely caused by human activity. Host Steve Curwood talks with Senator Jeff Bingaman, Democrat from New Mexico who wrote the resolution. The Senate also approved a set of voluntary climate change programs proposed by Nebraska Republican Chuck Hagel. Hagel's amendment does not cap emissions but, instead, focuses on tax breaks and other incentives to industry to come up with low emission forms of energy technology. Host Steve Curwood talks with Senator Hagel about his bill. Also, Washington correspondent Jeff Young gives us the highlights of debate on a massive energy bill making its way through Congress and some insight into changing attitudes about climate change.
