The first volume of the Fourth National Climate Assessment (NCA4) report, known as the Climate Science Special Report (CSSR), was released Friday, November 3rd, 2017 by the U.S. Global Change Research Program after years of writing and reviewing by experts from 13 federal agencies and the broader research community.

Check out recent staff changes, research and program highlights, recent events, and MAPP Task Force updates.

Two new datasets, funded in part by NOAA Research’s Modeling, Analysis, Predictions, and Projections (MAPP) Program, now provide easy public access to 60 terabytes of climate forecasts containing predictions of rainfall, temperature, winds and other variables at the subseasonal level (two weeks to two months ahead).

New research, funded by CPO's Modeling, Analysis, Predictions, and Projections (MAPP) program, shows that the polar vortex has shifted towards more frequent weak states and fewer strong states over the past few decades, with subsequent cold extremes seen during Eurasian winters. 

As an important milestone for NOAA’s ongoing efforts, researchers from universities, NOAA OAR research laboratories and the National Weather Service (NWS) recently met to discuss efforts to improve S2S predictions.
