When it comes to the reconciliation bill, fights over health care and taxes \u2014 which are still unresolved by the way \u2014 have been the focus while other major policy areas like climate have received little attention. \n\nBut that\u2019s about to change. \n\nHouse committees have now marked up the key pieces of climate policy. And with the Senate\u2019s return this week, all eyes will once again be on Sen. Joe Manchin, who as chairman of the Senate Energy and Natural Resources Committee, is responsible for writing the single most important piece of climate legislation. \n\nIt\u2019s a bill that could determine whether the United States meets an aggressive emissions-reduction target scientists say is needed to avert global catastrophe (no pressure).
