To adapt to climate change, we need to build our cities like we did in the past – moving towards a climate-responsive urban design. We’ll will talk about the increasing risks posed by heat and the proven, cost-effective solutions to mitigate its impacts. This includes large-scale efforts to increase greenery; lightening streets, rooftops, and the right of way (which can represent up to 30-35% of total land area in cities) to absorb less heat; and better building design. We will use concrete examples from cities such as Milan, LA, NYC, Nashville, Tokyo, London, Paris, and Medellin to show how cities are adapting to the realities of a changing environment and extreme heat and outline how they need to be bolder and more aggressive as temperatures rise and more people flock to cities.
