A milestone in advancing the physical science basis of climate variability and change

The Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report on “The Physical Science Basis” of climate change has been completed and will appear online on Sept. 30, 2013. This report represents a milestone in the understanding of the Earth system and climate science. Scientific research funded by NOAA’s Climate Program Office (CPO) is foundational to advancing IPCC reports. CPO supports climate science research reflected in the IPCC’s report through its Climate Observations and Monitoring (COM); Earth System Science (ESS); and Modeling, Analysis, Predictions, and Projections (MAPP) programs.
