This project develops a web interface to communicate and visualize the uncertainty of climate change forecasts and impacts on the economy. This tool will disseminate a great deal of data with a high degree of spatial resolution, in an interactive, informative and visually compelling way. This wealth of data cannot be typically published in peer-reviewed articles due to space limitations and it never reaches other scientists, policymakers and the public at large. For example, it is now possible to estimate probability density functions of climate change impacts on the economy at the county level, for different scenarios of emissions, over different time horizons. These probability density functions allow displaying the full range of potential impacts, including rare outcomes. Unfortunately, it is hard to imagine how to display thousands of graphs or tables – one for each county of the USA – using traditional methods. The application that will be developed will make it easy to quickly access large datasets on future climate change projections and economic impacts, using interactive maps, tables and animations.
