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.

    COP 21 Not a Silver Bullet on Climate Change

    The Paris climate conference cannot provide the engine that will drive a solution to the world's climate change challenge. Rather, it can best serve as a mediator that will help guide and structure the swirling, bottom-up process of radical change that is the best hope of preserving Earth's climate.

    Adapting to a Hotter World

    Because climate change is largely irreversible, mitigation alone won't solve the problem. While mitigation will prevent even greater, future climatic changes, adaptation — efforts to adjust to climate change's effects — will prepare the world for a new set of living conditions, whatever they may be.

    Opponents of action to mitigate climate change often suggest that regulation could have a negative impact on jobs, but stakeholders need to consider benefits, too. For instance, lower emissions could produce savings in the form of lower health care costs, reductions in premature death, and greater well-being.

    President Obama's visit to India last week was hailed in many quarters as a landmark event, perhaps signaling a new era of cooperation. In reality, the concrete takeaways were quite modest: there was no breakthrough on climate change, trade, or civil nuclear liability. But the trip should nonetheless be judged a success.
