LINCOLN, Neb. (AP) — Nebraska groups are planning to rally outside the governor’s residence to call for state action to address global climate change.

Members of the Sierra Club, Bold Nebraska and the Nebraska League of Women Voters will gather outside the residence Wednesday along with students from the University of Nebraska-Lincoln.

The groups say they will present petitions asking state officials to submit a Clean Power Plan to the federal government.

Nebraska has joined a coalition of primarily conservative states that is suing to block the new federal regulations, which seek to reduce power-plant emissions. Gov. Pete Ricketts has said he’s concerned that the rules will prove costly and burdensome.
