[URBAN NOTE] Five notes about cities: trains, climate change, allergies, India, fires, Midwest map

• MTL Blog looks at the proposal for a sleeper train connecting Montréal and New York City. (Can Toronto get one too, please?)
• Lauren Pelley reports for CBC about how climate change leads, through increased pollen production, to worse allergies for residents of cities in Canada.
• Guardian Cities reports that the fires in Alaska, too, outside of Anchorage, are things that dwellers of cities will have to get used to.
• The heat island effect, CityLab warns, will be a major threat to life in the cities of India.
• CityLab does an interesting crowdsourced map, tracing the boundaries of the American Midwest.
