Climate change: Obama orders steeper cuts from power plants

WASHINGTON (AP) — Aiming to jolt the rest of the world to action, President Barack Obama moved ahead Sunday with even tougher greenhouse gas cuts on American power plants, setting up a certain confrontation in the courts with energy producers and Republican-led states.

In finalizing the unprecedented pollution controls, Obama was installing the core of his ambitious and controversial plan to drastically reduce overall U.S. emissions, as he works to secure a legacy on fighting global warming. Yet it will be up to Obama's successor to implement his plan, which reverberated across the 2016 presidential campaign trail.

Opponents planned to sue immediately, and to ask the courts to block the rule temporarily.
