President Biden is poised to sign the historic Inflation Reduction Act that will, among other things, enact sweeping changes to the US energy sector and efforts to fight climate change. Tiernan Sittenfeld, the senior vice president of the League of Conservation Voters, talks with guest host Shelley Hearne about the bill and its game-changing potential for the environment and public health. They also discuss why major climate legislation has failed in the past and what needs to be done to ensure that implementation is successful.
