The Baton Rouge Area Foundation publishes a quarterly report titled “Currents.” Their third-quarter issue offered an interesting exposé authored by Jeremy Alford, titled, “Is BR climate ready,” devoted to possible climate changes for Baton Rouge. Of particular note was Chicago’s preparations for a futuristic heat wave that would make the Windy City feel more like Louisiana’s Capitol City. Chicago’s mayor expects a warmer future that includes the replacement of its white oaks with cypress. The article outlines a 50-year model that suggests hotter summers, fewer afternoon showers and within 50 to 100 years, 2,400 miles of major roadway will be inundated by Gulf Coast sea-level rise. The Baton Rouge Area Foundation has created The Water Institute to address all aspects of rising water.
