Marin County just set a new record for the hottest Oct. 8 in history when San Rafael hit 108 degrees. Extreme heat has devastating consequences, especially for Marin’s growing older adult population and people who work outdoors. With each passing year, we experience how a changing climate can affect our lives – from prolonged heat waves to intensifying storms, sea level rise, more frequent flooding, and other threats. The longer we wait to act, the more severe the consequences will be.
