Global Climate Change


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.

    A Green Costa Rican COVID-19 Recovery

    Feb 24, 2022

    Before COVID-19 hit, Costa Rica had been taking a leading role in addressing the effects of climate change by investing in decarbonization. Could these same investments also accelerate Costa Rica's pandemic economic recovery and help address historical inequities?

    To Help Climate Migrants, We Must First Recognize Them

    Jan 28, 2022

    Despite the large and growing population displaced by extreme weather, there is no common definition of a “climate migrant.” Once we get a clearer sense of just who is a climate migrant, policy efforts should begin focusing on the full fabric of life in our communities, creating systems that will help migrants become a part of that fabric in safe and dignified ways.
