The Supreme Court is set to hear a case its conservative majority could use to hobble Biden administration efforts to combat climate change.

The administration already is dealing with congressional refusal to enact the climate change proposals in President Joe Biden’s Build Better Back plan.

Now the justices, in arguments Monday, are taking up an appeal from 19 mostly Republican-led states and coal companies over the Environmental Protection Agency’s authority to limit carbon dioxide emissions from power plants.

The court took on the case even though there is no current EPA plan in place to deal with carbon output from power plants.
