All this talk about re-zoning, increasing green spaces and limiting sprawl is not helpful. Imho such long-term planning considerations are just a means of delaying action. Cities need things that can be implemented and show results in years, not decades. We must adapt the cities largely as they stand today. Quick solutions are things like painting surfaces white, insulating buildings and connecting spaces via enclosed walkways to minimize loss of AC air. Other options can be more regulatory, such as allowing people to install shades over windows irrespective of local zoning rules.
