  • Sea level is rising.
  • As sea level rises, it will drown low-lying coastal areas.
  • As sea level rise, storms will cause more coastal erosion further inland. During storms, sea level is abnormally high due to storm surge and higher waves. Set on an already higher sea level, erosional forces will get to places that were previously out of reach. Storms arriving coincidentally at high tide will do the most damage.
  • As sea level rises, storm surge associated with major hurricanes will reach higher onto land.
  • The sand on many beaches will continue to be lost to erosion.
  • Low-lying nations, such as some Pacific Island States may disappear altogether, causing people to have to move.
