Extreme high tides, or “King Tides”, occur at a few specific times during the year when the moon is closest to the Earth. During these high water events, we can see what the average water levels might look like in the future, given projected sea level rise. The Witness King Tides project invites people to visit the shoreline and capture images of important places threatened by sea level rise.
King Tides images help local communities and decision makers understand the challenges we will face given a changing climate. Ecosystems, infrastructure and people will be impacted by this phenomenon. In some places the impacts are hard to fathom… Seeing is believing.
