Just found this informative (and somewhat unnerving!) website by the Calfornia Energy Commission that tracks the projected effects of climate change on local climates and how this influences how we plan our cities. There was also a recent NPR show about the City of Chicago’s Climate Action Plan: Preparing for a Warmer Planet. Many of their recommendations include the same sustainable practices we recommend: using permeable pavement, climate appropriate and drought tolerant plantings, and rainwater harvesting.
Check out the website, lots of interactive maps, articles, and other info!
