About Us

CCASS/NNCAP welcomes Valerie Small!

Dr. Valerie Small (Apsaalooke'-Crow) has joined the Native Nations Climate Adaptation Program as an Assistant Research Scientist. Dr. Small will be working with Tribes in the Southwest Region in collaboration with CCASS and NNCAP within the Institute of the Environment as well as the Southwest Climate Science Center (SW CSC). She will develop and deliver educational training modules to increase their environmental technical capacity in preparing for, as well as predicting near-term/future effects of climate change.

Prior to joining the UA, Valerie was a training consultant with Colorado State University, Natural Resource Ecology Lab (NREL), working with the North Central Climate Science Center. Her experience includes developing and conducting training and research to support North American Indigenous Tribes adaptation planning efforts to prepare for the effects of a warming climate.  

Climate Assessment Released

The Third National Climate Assessment report (NCA3) was released May 6.  Written by more than 240 authors and overseen by a 60-member federal advisory committee, the third National Climate Assessment, or NCA3, is the most comprehensive national effort to assess the science and effects of climate change in the United States.  

National Climate Assessment Panel Discussion

At the University of Arizona on May 8, a panel of National Climate Assessment authors will comment on the report and its implications for the Southwest region, as well as the nation as a whole.  They include Katharine Jacobs, who directed the NCA while serving in the U.S. Office of Science and Technology Policy in the White House before returning to the UA as director of CCASS.  Panelists will briefly discuss various aspects of the report and field questions from the public and media.
