New York's former mayor and Vancouver's mayor Gregor Robertson are pushing for climate change policies at the city level.
But culture critic Jeffrey Melnick says the multiple traumas of Sept. 11 are also woven in more subtle ways through American culture, even 10 years on.
Melnick says shows like “Lost” and films like “Chicken Little,” neither of which mention Sept.11, were about the terrorist attacks.
Melnick says there’s also art focused on the aftermath, what he calls “September 12 Art.”
September 12 art includes films like Steven Speilberg’s “Munich” and music by Hip Hop artists like Eric Sermon and M.I.A and Jay Z’s collaboration the British DJ, Punjabi MC.
