Global Climate Change

Featured

Global climate models developed by the UN's Intergovernmental Panel on Climate Change predict glacial retreat, rises in sea level, and other impacts on human and natural activity, from agriculture to migratory patterns. RAND researchers have studied and are continuing to examine the effects of climate change, particularly how governments and businesses respond to both observed changes and projected scenarios.

    When It Comes to Climate, Look for Vulnerabilities in Policy, Not Science

    Aug 4, 2017

    Federal policymakers have picked up on the concept of red teaming — actively seeking out one's own vulnerabilities. While red teaming may not make sense for climate science, it does offer great benefits when weighing climate policy options.

    Urban Responses to Climate Change

    Dec 7, 2016

    More than 80 percent of the U.S. population lives in urban areas. Thus, cities lie at the epicenter of America's response to climate change. Analysis can inform how cities choose strategies and allocate resources.

    How Hot Is Too Hot? Rising Temperatures and the Workplace

    Climate change is here. Future extreme heat waves are a given and will likely grow in intensity, geographic reach and duration. Plans need to be made now to ensure survival of the poorest, to protect outdoor workers and to adapt economic planning to what is increasingly becoming a hotter planet.
