Coastal areas around the pacific will be at increased risk of erosion and flooding if a projected increase in extreme El Niño and La Niña events occurs, according to a new study.
Researchers found that observed coastal erosion across the Pacific varies closely with El Niño events, independent of changes in sea-level rise. The researchers gathered data from 48 beaches between 1979 and 2012, eight of which were in the Pacific Northwest, including British Columbia.
