Sea level is rising, placing cities and infrastructure that line many coasts at increased risk of coastal flooding, storm surge inundation, shoreline erosion and retreat, and wetland loss. Global sea level rose during the 20th century, and observations and projections suggest that it will rise at a higher rate during the 21st century. However, sea-level rise is not uniform; it varies from place to place. Consequently, some states are seeking to incorporate local projections into coastal planning. The forthcoming National Research Council report Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future estimates the contributions to global sea-level rise (such as thermal expansion of ocean water and melting of ice sheets and glaciers) as well as the factors that influence sea-level rise along the U.S. west coast (such as atmosphere and ocean circulation patterns in the northeast Pacific Ocean and tectonics along the coast). It then uses models and historic trends to project sea levels for 2030, 2050, and 2100, both globally and along the California, Oregon, and Washington coasts.
