We've talked here before about how the Chesapeake Bay region is especially at risk from global warming because of how increasing sea levels will intensify effects already being seen from natural geological subsidence. The land mass is already sinking due to plate tectonics- one plate is being forced under another one. Combined with rising sea levels from global warming, Maryland is predicted to lose significant amounts of coasts and islands. A Washington Post article from Monday 10/25/2010, entitled Losing battle against the bay, presents a modern day Don Quixote's struggle and failure to save a two-story Victorian home on Holland Island.
Abandonment and retreat.For the past 15 years, a former minister named Stephen White had been trying to
hold back the water, protecting the house's foundations with timbers and rocks
and sandbags."I lie in bed and feel like I failed. And then I remember that
I did everything that I could," said White, who had first visited the abandoned
island as a boy.Sea levels in the Chesapeake, scientists say, are rising faster than they are in some other coastal regions of the United States. One reason is ancient: The land here has been slowly sinking for thousands of years, settling itself from bulges created by the weight of Ice Age glaciers. The weight of glaciers to the north pushed the Earth's crust down, and the crust in this area went up like the other end of a see-saw. Now, the whole region is slowly sinking again.
The other reason is modern: climate change. The Earth's oceans are rising, scientists say, because polar ice is melting, and because warmer water expands. They have noticed the effect of climate change more in the past couple of decades, government scientists say.
These two factors mean that seas rise a tenth of an inch annually, eroding about 580 acres of Maryland a year, according to the state. The loss of land is all around the bay but is most noticeable on the low islands.
...It definitely won't, however, be the end of the Chesapeake's erosion problems. A few miles away, a watermen's community on Smith Island is just a few inches above the waves. And Maryland is contemplating how to, in one official's words, "facilitate abandonment and retreat" when faster-rising waters eventually threaten towns on the Eastern Shore's mainland.
