From the intermountain West to the subtropical Florida peninsula, we must unite to cut carbon emissions.

When it comes to confronting the challenge of climate change, cities are on the front lines.

From rising seas submerging coastal property to precipitation changes in the desert, climate impacts are here—and undeniably local. Climate change may have once been the ultimate slow-moving and global threat, but our residents and our critical infrastructure are already feeling its effects. The threats to our economies are serious enough that the risks of continued inaction can no longer be ignored.

Mayors like us are elected to keep our communities strong, to keep our residents safe and to provide critical services, no matter what a governor, attorney general or member of congress might have to say about climate change. That is why our cities have joined with more than 50 other local governments and thousands more represented by the U.S. Conference of Mayors and National League of Cities to file an amicus brief in support of the Clean Power Plan.
