The Government Accountability Office (GAO) is conducting several climate change and adaptation-related studies at the moment. They recently released their study: “CLIMATE CHANGE: Future Federal Adaptation Efforts Could Better Support Local Infrastructure Decision Makers,” that examines:
1. The impacts of climate change on roads and bridges, wastewater systems, and NASA centers;
2. The extent to which climate change is incorporated into infrastructure planning;
3. Factors that enabled some decision makers to implement adaptive measures; and
4. Federal efforts to address local adaptation needs, as well as potential opportunities for improvement.
This study includes high-level recommendations for executive action in this area which you might be interested in. Here is more information on the study: http://www.gao.gov/products/GAO-13-242.
