Action man Arnold Schwarzenegger has been named an honorary ranger by officials at the U.S. Forest Service. The actor, who served as California governor from 2003 to 2011, has been recognised for his continued efforts to combat climate change. A statement from agency bosses reads, "Thanks to Governor Schwarzenegger, California is now well on its way to meeting its targets through a ground-breaking mix of measures, including a low carbon fuel standard, a renewable energy portfolio, and a cap-and-trade program. "Governor Schwarzenegger also approved tough new vehicle fuel economy standards that have since been adopted at the national level." The Terminator star, who co-founded the non-profit R20 Regions of Climate Change organisation, joins Betty White and Rolling Stones keyboardist Chuck Leavell as the only other honorary rangers in the agency's history, according to the Huffington Post.
