High Tide in Dorchester aims to foster a conversation about climate change and related impacts of sea level rise and erosion, and leverage that conversation into action. The focus, Dorchester County, MD, is already experiencing the future that increasingly faces coastal areas worldwide. This low-lying county on the Eastern Shore of the Chesapeake Bay is the fourth largest of Maryland’s 23 counties by land area, but it is destined to drop to the 14th largest by 2100 — or sooner — as waters rise and erosion worsens. Dorchester is the coal miner’s canary; ground zero for the Chesapeake Region.
