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.  

USACE's lead climate scientist to speak

Thursday, April 27, 2017

Jeff Arnold, the lead climate scientist at the US Army Corps of Engineers, will talk at UA on 4/27 on "Decision Support for Uncertain Climate Futures: The Confidence Trap" in Room S107 of the ENR2 Building at 1064 E. Lowell St.

Dr. Arnold works on the technical and science-policy concerns of climate change for water resource applications. He co-directs the USACE National Climate Preparedness and Resilience programs and leads the agency’s integration of climate change mitigation with climate adaptation.

For more than 200 years, the U.S. Army Corps of Engineers (USACE) has had primary responsibility for water resource operations on most major U.S. river systems. Managing the impacts of climate variability and change is a significant challenge; projections of specific, possible threats and impacts to regional scale hydrology are still uncertain enough that explicit guidance is needed on their interpretation and use. This talk will describe new approaches to helping decision makers understand uncertainties in managing real river systems, aiming to avoid communication issues about confidence while respecting uncertainties.

Arnold's visit is co-sponsored by the Center for Climate Adaptation Science and Solutions and the Water Resources Research Center.
