Many airports, and by their nature ports, are in the low elevation coastal zone, making them especially vulnerable to flooding and sea level rise. Under a 2°C scenario, the number of airports at risk of storm surge flooding increases from 269 to 338 or as many as 572 in an RCP8.5 scenario; these airports are disproportionately busy and account for up to 20% of the world's passenger routes . Airport and port operations could be disrupted by icing of aircraft wings, vessels, decks, riggings and docks . Warming will increase microbiological corrosion of steel marine structures . Fog, high winds and waves can disrupt port and airport activity, but changes are uncertain and with regional variation .
