Sea level rise for the coasts of california oregon and washington past present and future this study provides the first comprehensive regional projections of the changes in sea level expected in california oregon and washington posing serious risks to the infrastructure development and wetlands along this 1600 mile shoreline. Sea level rise for the coasts of california oregon and washington past present and future explains that sea level along the us west coast is affected by multiple factors including climate patterns effects from melting ice sheets and geologic processes provide feedback on this project. As more and more states are incorporating projections of sea level rise into coastal planning efforts the states of california oregon and washington asked the national research council to project sea level rise along their coasts for the years 2030 2050 and 2100 taking into account the many factors that affect sea level rise on a local scale
