New research data, from 48 beaches across three continents and five countries bordering the Pacific Ocean, suggest the predicted increase in severeEl Nino and La Nina events will exacerbate coastal erosion irrespective of sea level rise

The severe winter erosion led to lane closures of the highway and an emergency, $5 million revetment along the base of this bluff. This storm damage occurred during the 2009-2010 El Niño, which, on average, eroded the shoreline 55 meters that winter. Courtesy: USGS
