USGS scientists, including CASC staff, play key role in the Fifth National Climate Assessment. 

On November 14, the U.S. Global Change Research Program (USGCRP) announced the release of the Fifth National Climate Assessment (NCA5). NCA5 is the most up-to-date and comprehensive assessment of climate change in the United States, providing authoritative, decision-relevant information on how people across the country are experiencing climate change, the risks we face now and in the future, and actions underway to reduce greenhouse gas emissions and build resilience. The USGS has been involved in every NCA since the first report was released in 2000. 

The release of NCA5 marks the culmination of a four-year process in which dozens of USGS scientists have participated. USGS scientists were directly involved in the development of NCA5 through leadership roles, as authors, and as technical contributors. Among USGS scientist contributors are a number of CASC staff, in the roles outlined below:

Shawn Carter, National CASC Senior Scientist 

Ecosystems, Ecosystem Services, and Biodiversity chapter 

Mari-Vaughn Johnson, Regional Administrator of the Pacific Islands CASC

Aparna Bamzai-Dodson (North Central CASC), Carolyn Enquist (Southwest CASC), Olivia LeDee (Midwest CASC), Jeremy Littell (Alaska CASC), and Stephanie McAfee (Southwest CASC). Kate Malpeli (National CASC) served in a technical contributor role. 

Several CASC consortium leads and Tribal Liaisons also served in author and technical contributor roles.
