RODANTHE — Coastal geologist Stan Riggs, who tracks the ups and downs of North Carolina’s shoreline, needed a bullhorn to make himself heard above a roaring nor’easter that had toyed with the Outer Banks for two days.
He climbed down from the ridge of a DOT-built dune narrowly separating N.C. 12 from the boisterous Atlantic Ocean. A bleached house named WAVE BREAKER seemed to be stilt-walking into the surf – but, really, the island itself was slipping out from under this cottage in a shrinking subdivision called Mirlo Beach.

Other than tidal effects, especially from storms, the average water level around the planet DOES NOT CHANGE.
It is the ground which moves up and down.
Leftists see world as static but reality is constantly trying to show them it isn’t.
B-B-But obama was supposed to FIX that, wasn’t he?
Ice pellets from outside the Earth's atmosphere constantly pelt the Earth. Water vapor is also drawn out of the Earth's atmosphere by the Sun.
Apparently a slightly larger amount of water comes in than goes out.
“It could also be land levls are sinking”
Subsidence is certainly occurring in the DC area. From time to time you may see wild articles about the sea level rise along parts of the Potomac, but it’s a little of the local rise, and a bunch of the subsiding of the former swamp land in the area.
The 'land' is constantly rising and falling all over the planet.
In most cases it is very slowly, but the beaches rise and fall with the tides.
There is clearly a long-term sea level rise...though the exact measurements are highly uncertain, and vary according to measurement method.
The main theory on the current (this millenium) rise is that it is primarily from the expansion of water from long-term warming, as opposed to the MUCH larger rises from earlier deglaciation at the end of the ice age.
Well... the overall sea level isn't rising by any significant amount.
As the ice caps increase, they increase pressure on the ground beneath them. That ground is soaked with water. The pressure squeezes out the water and .... things tend to balance out around the planet.
We had a great local resource down there in the Woods Hole Oceanagraphic Institute. I learned a lot from there about sea level rise and dontinental subsidence.
One thing for sure: Cape Cod wasn't there until the last Ice Age dropped its final load of boulders, gravel and sand about 15,000 years ago and I'm willing to bet that it won't be here 15,000 years from now.
I have to take better care of myself though if I'm going to be here to prove it. :O)
There is more water BENEATH the surface of the Earth, than there is ON the surface.
Sea levels have certainly risen over the thousands of years, even hundreds. It’s not due to an increase in the amount of water...nor is it due to the warming cycle over the last few decades, or century and a half. It’s much longer term, as the oceans are huge.
EXACTLY!
The rise in sea level is within the normal cycles the Earth goes through. Once we hit the next ice age, due any time now, sea level will start dropping.
What will Al Gore and his ilk do then?
It's all sand. Hurricanes going up the coast will create massive storm surges, first pushing westward, then pulling eastward; and sometimes north or south parallel to the shore. Occasionally, Nor'easters blow in, and push everything into the inland swamps (well, not quite everything). Then four times a day, the tidal flow moves tons of sand between the ocean and the sounds. It never stops. And all the Global Warming and all the Global Cooling doesn't make a bit of difference.
This is the nature of a sandy coastline.
I concur.
Global warming rise of the sea being darn near nothing.
That entire barrier island has migrated east and west a few inches to a few feet to a few yards a year since people first started noticing such things. Two blocks or so inland from the current beach there are remains of a shipwreck that was well east of the surfline when it sank and broke up.
Sea level is the level relative to the adjacent land. How much is more water, and how much is land subsiding?
The Outer Banks are barrier islands. The natural tendency of any barrier island chain is to very slowly “walk” to the mainland with constant wave and prevailing wind action. It is natural, nothing more. To conclude that the ocean is rising rather than the barrier eroding is a fool’s errand. My question is are houses being overtaken by the “rising” ocean on the sound side of the Outer Banks? I would very much doubt it./p>
The water is rising just as it should, the Mississippi river dumps about 500 tons of sediment a year into the gulf. Now lets add in all the rivers, streams and beach erosion that takes place all over the world. If I don’t dredge out the ponds on the ranch about every 5 years they hold less and less water.
All all this excitement over 5 inches? yeah that sounds like a liberal
