For an oceanfront city, Halifax is strangely well situated to handle climate change, due to the steep rise out of the harbour. The waterfront, Historic Properties, and the shipyards are vulnerable, but the bulk of the city is well above sea level. (Dartmouth has some of that protection too, but is much lower and more susceptible in the long term). Compare to NYC, say, much of which could basically be a floodplain in 50 years. Or worse, Boston, which is low-lying, filled with rivers, and a huge portion of which is built on landfill.
This tool is a fun/scary way to look at how sea-level rise could affect different parts of the world.
Of course we could see more hurricanes/extreme weather, which is bad for other reasons.
But as to what Waye said: Toronto got 120 mm of rain. There was a lot of hand-wringing in the press about why the city couldn't handle the storm, but really, that amount of water is impossible to prepare for unless you basically turn the city into a giant drainage system. The city had never, in recorded history, had that much rain in a 24-hour period before, and most of it fell within only one hour. Considering the extremity of the downpour, the aftermath wasn't
so bad
