Our climate system behaves in ways that make it challenging for people to fully anticipate and understand the long-term consequences of their decisions. Around the world, global citizens are grappling with how to preserve a viable future, business leaders are trying to navigate a complex energy landscape, and governments are attempting to steer their economies towards low carbon energy while improving the quality of life for their citizens—all in the context of complex dynamic systems whose behaviors are shaped by the interplay of investment decisions, policy choices, technological progress, and the slow turnover of existing infrastructure. Our climate models, tools and analysis are designed to help people understand, through interaction and exploration, what speed and scale of reductions in emissions will work to meet our climate goals. We straddle the fence between science and policy to make it all more accessible to those who are making decisions about our future.
