Sea level is not as level as you might imagine.

The ocean at Bermuda is about three feet higher than the ocean at the mouth of Chesapeake Bay—an ocean that would seem poised to gush downhill and drown Tidewater Virginia.

It doesn’t, because the earth, whose rotation is what causes the ocean’s Bermuda-to-Bay slope, keeps on spinning.

It’s actually more complicated than that, explains oceanographer Bill Boicourt, emeritus at the University of Maryland’s Horn Point laboratory, on the front lines of researching climate change and sea level rise as it affects the Chesapeake.

As Horton explains in the film:

“If the consequences of global warming and rising sea levels and the worsening erosion and the high tides they bring seem a little hazy to you, come take a tour of Dorchester County, where the future is now.   Check out the dying forests, sunken tombstones and waterlogged home foundations of communities going into the Bay. Plan a bicycle trip down some of the Mid-Atlantic’s most scenic country roads, but check your tide-chart before you go. Cross miles of open water in the heart of a national wildlife refuge where in living memory a river wound between marshy banks.  A child today in this county may see her yard, her playground, disappear at a much-accelerated rate as the changing climate makes what I experienced seem like just a warm up. In another century, maybe less, this fourth largest county in Maryland by land area is going to be the 14th largest out of 23 counties.”
