An Overview of Potential Economic Costs to Oregon of a Business-As-Usual Approach to Climate Change

Abstract

Extensive research shows that Oregon and other western states already have experienced noticeable changes in climate and predicts that more change will occur in the future.1 Much of this change is having and will continue to have negative economic consequences. Some negative effects are readily recognized: warmer stream temperatures during summer stressing salmon and trout populations, prolonged drought destroying farmers’ crops, and rapidly growing insect populations attacking trees. In response, families, businesses, and communities are considering actions that would reduce the emissions of carbon dioxide and other greenhouse gases (GHGs) that contribute to climate change. Amid all this activity, many have concluded that such actions should not be undertaken because their costs are too great. They reach this conclusion, however, without first seeing what the costs would be of not taking these actions and allowing climate change to continue unabated.
