Walter Orr Roberts Memorial Public Lecture: From Droughts to Floods & Back Again? Learning and Adapting in an Uncertain Climate

Date: 
Tuesday, September 11, 2018
Authored by: 

NOAA senior science advisor Roger Pulwarty reflects on how science and learning can help us adapt to an uncertain future in the semi-arid Intermountain West and beyond. In a humorous and entertaining manner, the lecture highlights innovative lessons from communities with which Dr. Pulwarty has worked and addresses barriers and opportunities for applying research to support communities in managing risk and developing new networks for sharing knowledge.
