The Climate Emulator is a web-based representation of the research of Elisabeth Moyer at the University of Chicago. It gives the user a visual front-end to a model that can predict global temperature change based on changes of the concentration of carbon dioxide in the atmosphere. It is being developed with the Center for Robust Decision Making on Climate and Energy Policy at the University of Chicago.
It is a work in progress, with many features (and of course bugfixes) planned for the future. Some of these include: expanding the site to include precipitation data, allowing CSV downloads of user-driven scenarios, and world regions based on political boundaries rather than climatological ones.
