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.

    Navigating the Uncertain Path to Decarbonization

    Deep decarbonization can reduce the risk of climate change, and it offers opportunities to reimagine energy, transportation, and infrastructure. But it could also fail in many ways. Diverse, independent actors need a shared understanding of its complexity and deep uncertainty to design a solution to this challenge.
