The earth is growing warmer, mainly due to human production of greenhouse gases. Host Don Fitz and Environmental Science instructor Dan Lehocky discuss longer periods of extreme heat, the frequency of heavy rainstorms, dryer soils and increased droughts. They cover potential responses, including putting power lines underground, destructive tree-trimming, and storm water management. This Green Time (No. 263) is produced by the Gateway Greens in conjunction with KDHX. Call 314-727-8554 or contact fitzdon@aol.com for information.
