American communities are the wellspring of our national pride, security, and vitality. Local leaders and citizens have worked together to build strong, prosperous, and livable communities in America for centuries. Today, climate change is impacting our communities and our essential built, social, and natural systems worldwide. Many more Americans and communities have been affected by impacts on property, financial systems, infrastructure, and health from volatile weather, changing rainfall, and extreme temperature shifts. Now that these impacts are visible from our kitchen windows, Americans can no longer dismiss climate change as a remote possibility in a far-off land. And, local communities are bracing for more changes to come.
