How Oregon would be affected by further sea level rise

Global climate change is warming oceans, melting polar ice and causing sea levels to rise around the world. Scientists predict that in the next 80 years, waters will rise at least 3 feet, but that a rise of more than 6 feet cannot be ruled out. That level of increase would submerge small islands in the Columbia River and leave much of Sauvie Island underwater as well. The National Oceanic and Atmospheric Administration has released a new mapping tool that helps people visualize various levels of sea level rise around Oregon. Jonathan Allan is a coastal geologist with the Oregon Department of Geology and Mineral Industries. He joins us to discuss how sea level rise is already impacting Oregon.
