Notice of Availability of Draft Scientific Assessment for Public Comment

The National Oceanic and Atmospheric Administration (NOAA) is publishing this notice on behalf of the United States Global Change Research Program (USGCRP) to announce the availability of a draft assessment, the Climate Science Special Report, for a 45-day public review, collected comments will be carefully reviewed by the relevant chapter author teams. Following revision and further review, a revised draft will undergo final Federal interagency clearance. Context: The U.S. Global Change Research Program (USGCRP) is mandated under the Global Change Research Act (GCRA) of 1990 to conduct a quadrennial National Climate Assessment (NCA). Under its current decadal strategic plan (http://go.usa.gov/3qGU4), USGCRP is building sustained assessment capacity. The sustained assessment supports the Nation's ability to understand, anticipate, and respond to risks and potential impacts brought about by global environmental change. As part of the ongoing NCA process, a Climate Science Special Report is being developed to inform the assessment. The last NCA from 2014 (NCA3: http://nca2014.globalchange.gov) and the process to develop it provided a foundation for subsequent activities and reports. This special report provides an update to the physical climate science presented in the 2014 National Climate Assessment (NCA). Specifically, the special report updates Chapter 2 and Appendices 3 and 4 of the 2014 NCA (http:/ /www.globalchange.gov/nca3-downloads-materials). The report provides updated climate science findings and projections, and is an important input to the authors of the next quadrennial NCA, expected in 2018.
