A massive methane leak may soon end, but its environmental impact is still being weighed. A scientist says it won't have a big effect globally, but it's a setback in efforts to curb greenhouse gases.

The U.S. Supreme Court has put a hold on the Obama administration's Clean Power Plan, which would significantly regulate coal, after 27 states sued over the proposal. Among them was Wyoming, which produces more coal than any other state. NPR reports on how the court's stay is being received in coal producing states.

Replacing fossil fuels with renewable energy to combat climate change will require trillions of dollars in investment. Cheap prices for fossil fuels are making that transition a bit more complicated.

It's the largest city in the U.S. to commit to using only renewable energy. And even though stakeholders are on board, trouble could be brewing over how to implement the plan.
