There is increasing pressure on the science community not only to understand how recent and projected changes in climate will affect Earth's global environment and the natural resources on which society depends but also to design solutions to mitigate or cope with the likely impacts. Responding to this multidimensional challenge requires new tools and research frameworks that assist scientists in collaborating to rapidly investigate complex interdisciplinary science questions of critical societal importance. One such collaborative research framework, within the NASA Earth sciences program, is the NASA Earth Exchange (NEX). NEX combines state-of-the-art supercomputing, Earth system modeling, remote sensing data from NASA and other agencies, and a scientific social networking platform to deliver a complete work environment. In this platform, users can explore and analyze large Earth science data sets, run modeling codes, collaborate on new or existing projects, and share results within or among communities (see Figure S1 in the online supplement to this Eos issue (
