It's already happening, and US military planners are already factoring it in. "The lack of rain and snow forced farmers to tear out their apple orchards by the acre. Wine grapes are withering on the vine. Mileslong irrigation canals leak and crumble." #ClimateLab www.seattletimes.com/seattle-news...

This timely & critical scholarship needs funding. The ClimateLab data shows rightward shift in U.S. political preference will lead to less support for walkable communities w/o changes. Hope your research can change messaging + show how to include sustainable elements of Republican city preferences.
