“Within a few decades, #Canadians in every part of the country will be faced with an inescapably altered #geography. #SeaLevels will rise up to half a metre on the #EastCoast by 2060 and approach a full metre by century’s end. Levels on the #WestCoast will rise more slowly, but the more urbanized coastline around #Vancouver and lower-lying communities will require massive upgrades to the #dikes keeping them dry.
