In the face of a changing global environment, knowledge is power. Advancing the Science of Climate Change, one of four panel reports from the America's Climate Choices project, maps out the realm of our accumulated knowledge regarding climate change and charts a path forward, urging that research on climate change enter a new era focused on the needs of decision makers. In this video, the leaders of that panel, Drs. Pamela Matson and Thomas Dietz, describe the panel's key findings and the lines of evidence that brought them to those conclusions.

Climate change poses clear threats to human societies and natural ecosystems. The panel on Limiting the Magnitude of Future Climate Change, part of the America's Climate Choices project, calls for the United States to respond to these threats by starting now to change the way we use and produce energy. In this video, several members of the panel discuss its conclusions, including a proposal for an emissions budget to guide U.S. policy as well as measures that might be taken to reach that budget's goals.

In response to a request from Congress, the National Academies have launched America's Climate Choices, a suite of studies designed to inform and guide responses to climate change across the nation.
