Work the Climate Calculator to see if you can make the choices needed to reduce the global average temperature enough to save the world from the most disastrous consequences of climate change. Or spin the Greenhouse Gamble roulette wheels to compare the likely impact of different climate policies on the rate of global warming. Learn how researchers at the MIT Joint Program on the Science and Policy of Global Change are combining scientific knowledge with policy analysis to inform decision-making on global environmental challenges that include climate change, air pollution, food insecurity, water shortages, biodiversity loss, and more.
