HOUSTON (AP) - A bipartisan group of mayors from across the country have unanimously approved a resolution calling on cities to use natural solutions to fight the impacts of climate change.

Attendees of the U.S. Conference of Mayors voted in Dallas on Monday on the resolution that encourages cities to use nature to “protect freshwater supplies, defend the nation's coastlines, maintain a healthy tree and green space cover and protect air quality,” sometimes by partnering with nonprofit organizations.

The resolution was backed by Austin Mayor Lee Leffingwell, Houston Mayor Annise Parker and Phoenix Mayor Greg Stanton.

Republicans and democrats remain deeply divided over how to deal with climate change. Although science shows human industrial activity is contributing to global warming, some conservatives remain skeptical.
