Across the United States, the impacts of climate change are already in evidence and projected future impacts will have significant consequences. The range of possible future climate conditions demands a new paradigm for managing and protecting our people, resources, and infrastructure. The panel report, Adapting to the Impacts of Climate Change, urges consideration of a variety of potential climate futures and associated impacts for which we must prepare, some well outside the realm of current experience. The report calls for a national adaptation strategy to support and coordinate a decentralized network of adaptation efforts.
