If humanity is going to survive and thrive in the future, it's going to need strong cities. Two-thirds of people are set to live in urban areas by 2050 (according to U.N. estimates), putting great pressure on city planners to cope.
How well are they doing so far? A new report scores 50 cities both for their "vulnerability" (for example, to climate change) and their "adaptive capacity" (their ability to react), producing an overall "resilience" ranking. And, in fact, the news for North America isn't bad--as long as you believe the rankings. The top three cities are Canadian (Toronto, Vancouver, Calgary), and six of the top 10 are from the U.S. (led by Chicago and Pittsburgh in fourth and fifth places, respectively).
