The Oregon Climate Change Research Institute (OCCRI) is a network of dozens of researchers and professionals at Oregon State University, Portland State University, the University of Oregon, and other universities, agencies, and organizations. OCCRI also houses the Oregon Climate Service, which is recognized by the American Association of State Climatologists as Oregon’s state climate office. OCCRI is hosted by the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University.

We seek to achieve a climate-prepared Northwest by building a climate knowledge network, cultivating climate-informed communities, and advancing understanding of regional climate, its effects, and adaptation. We are proud to serve our state’s leaders, agencies, and fellow residents; engage with communities that may be affected disproportionately by climate change; and participate in training future generations of researchers, management professionals, and neighbors.
