Careful management of natural resources can help reduce the climate risks that the natural resource economy faces.

What is the OCAR4 Report?

The state continues to warm as a result of the heat-trapping gases emitted into the atmosphere from global activity. The 4th Oregon Climate Assessment Report (OCAR4) represents a convergence of evidence of the risks that Oregon is facing, and will face in a changing climate, drawing from the past three Oregon Climate Assessment Reports, the 4th US National Climate Assessment, and other peer reviewed literature, and other analyses performed by the Oregon Climate Change Research Institute (OCCRI) and research partners.
