This week, Democratic West Virginia Senator Joe Manchin said he cannot support the Build Back Better Act, which contains more than half a trillion dollars in climate investments. The White House has been negotiating with Manchin for months, hoping he would cast a key vote for the plan in the Senate, where their party's majority is razor thin.
Without Manchin's support, the Biden administration's most ambitious action on climate may be dead, and the U.S. could fall short of key goals to prevent the worst effects of climate change.
