evaluate the effectiveness of actions taken. Many actors are involved in such efforts. For instance, technological innovation will depend in large part on private sector efforts, while information, education, and stakeholder engagement systems can be advanced by nongovernmental organizations and state and local governments. But the federal government has important roles to play in all of these efforts as well.
RECOMMENDATION 3: The federal government should maintain an integrated, coordinated, and expanded portfolio of research programs with the dual aims of increasing our understanding of the causes and consequences of climate change and enhancing our ability to limit climate change and to adapt to its impacts.
RECOMMENDATION 4: The federal government should lead in developing, supporting, and coordinating the information systems needed to inform and evaluate America’s climate choices, to ensure legitimacy and access to climate services, greenhouse gas accounting systems, and educational information.
RECOMMENDATION 5: The nation’s climate change response efforts should include broad-based deliberative processes for assuring public and private-sector engagement with scientific analyses, and with the development, implementation, and periodic review of public policies.
Actively engage in international climate change response efforts. America’s climate choices affect and are affected by the choices made throughout the world. U.S. emissions reductions alone will not be adequate to avert dangerous climate change risks, but strong U.S. emission reduction efforts will enhance our ability to influence other countries to do the same. Also, the United States can be greatly affected by impacts of climate change occurring elsewhere in the world, and it is in our interest to help enhance the adaptive capacity of other nations. Effectively addressing climate change requires both contributing to and learning from other countries’ efforts.
RECOMMENDATION 6: The United States should actively engage in international-level climate change response efforts: to reduce greenhouse gas emissions through cooperative technology development and sharing of expertise, to enhance adaptive capabilities (particularly among developing nations that lack the needed resources), and to advance the research and observations necessary to better understand the causes and effects of climate change.
Coordinate national response efforts. Individuals, businesses, state and local governments, and other decision makers nationwide are already taking steps to respond to
