The National Oceanic and Atmospheric Administration (NOAA) recently released two reports that provide detailed comparisons of phases 3 and 5 of the Coupled Model Intercomparison Project (CMIP3 and CMIP5) for the United States. Understanding the strengths of these simulations and the differences among models is important for sustained assessment

A new white paper highlights outcomes from the first annual U.S. Climate Modeling Summit. The Summit brought together leadership from the country’s six premier climate modeling centers to strategize around priorities of national interest—from experimental efforts that move science forward to forecasts and projections that inform on-the-ground decisions.
