DEAL ISLAND, Md. — Steps from the water’s edge, men stumble groggily into the glow of Arby’s General Store, indifferent to the shifting ground beneath them. Waves lap the shore this summer morning as the sea steadily advances on an island lurching toward extinction.
Here is where a remarkable transformation is taking place: Scientists estimate that the surrounding waters of the Chesapeake region have risen a foot in the past century. As global sea levels continue to climb, the bay water could grow 2 feet by 2050 and another 3 feet or more by 2100, models predict. At that point, Deal Island would be almost entirely submerged.
The hope is to preserve Deal — just as other coastal communities are weighing their own futures in a world where the climate is unmistakably changing.
Climatologists are bracing for a slowing down of the circular system of ocean currents in the North Atlantic, which may be linked to a melting Greenland and may be helping the sea level to rise.
Finally, the land in the Chesapeake is sinking. Whereas the Earth’s crust here was pushed up thousands of years ago by the weight of ice glaciers to the north, water from those melting glaciers are now overtaking the land at a creeping pace.
“We know that this is significantly human induced because we have measurements of sea level rise and fall from several million years in the geological record,” Scott says. “You can say it is human induced because nothing in the geological record has something like this happening so fast — except since the 1900s.”

I think of it as delaying the next Ice Age. And our descendants will thank us for it.
Easily disproven by any historic photographs of Chesapeake Bay which will show the water level right where is it today.
How does one "brace" for an event that takes centuries to complete?
How does water rise by a foot there, yet nowhere else?
This story is nonsense.
Intentionally conflating subsidence with a rising sea level doesn’t lend much credibility to these claims.
Exactly. I suspect it's the land sinking, not the water rising.
I know nothing about the Chesapeake Bay area. Do you have access to or can show a web search which would confirm your statement?
Really? Who took and recorded the measurements 100 years ago? (crickets)
Here's a cartoon version of what's happening to make it easier for you to understand.

Hmm no mention of impact craters. Maybe 35 MY is outside their scope.
Tape measures work in both directions from both ends. The hardest part is deciding who is holding the stupid end.
Have we landed an excessive amount of marines there? I’ve heard that could sink an island.
Actually, the oceans have made great level changes in the recent geological past. For example, the oceans were almost 400 feet lower than they are today before the glaciers starter melting. I think this was about 13,000 years ago, a very brief geological span.
The moved the Hatteras light house because the land was wearing away.
“It wasn’t the weight of the glaciers that pushed the land up, you morons.”
One thing that glaciers do ( and the article does not mention) is push the land under them down, and when the ice melts away, the land rebounds up, for thousands of years. Coastal Maine is slowly inching upwards.
But the ice does not cause land away from the ice to rise, afaik.
I don’t think Chesapeake was under ice for the last Ice Age.
I live 20 miles from Deale MD......at one point this area had an ice sheet 2 miles thick, another time the area was the bottom of the ocean.....currently after 60 years I see nothing to indicate the sea is rising in the least.
65 million years ago Kansas was an ocean. The rise of the Rocky Mountains helped elevate Kansas above sea level. 20,000 years ago, parts of Kansas was under >500 ft. of glacier.
