Aladdin, I wouldn't want to own a beach front house, would you? OTOH I don't think there is much evidence of any meaningful rise yet. I know of a sixty year old concrete pier forty miles from here (Charlotte harbor) and it is at the same level as when it was built. Some of this stuff you read online about "sea level rise" is just propaganda. I don't know how many times I have read something about "global warming" submerging the island of Vanuatu. It is not that the sea is rising, the island has a heck of a big active volcano, and the place is unstable. Where I used to live in the Philippines, another very unstable place with lots of volcanoes and earthquakes, back in 1956 the whole port sunk into the sea six feet in an instant during an earthquake. Something like that is what is happening in Vanuatu. On the Georgia and Carolina coast you have lots of wave action to move the sand around. Take Jekyll Island off the Georgia coast, you have the north end of the island washing away, but the south end of the island has grown a mile longer. That happens here on the gulf too. Nearby Sanibel and Captiva used to be separated by a wide inlet, now it is filled in completely. Slagle

I was at a coastal science conference a few years ago and a coastal engineer from the west coast of USA showed a similar picture to the lower one you showed, with severe beach erosion. Then he showed pics from a few years later - sand dunes had built up to the point that houses had to be abandoned - filled up with sand. The fact is that sandy coastlines experience terrific changes, as sand moved offshore and back again, and up and down coast, in response to the wave climate. To attribute the changes observed in these two images to global warming and sea level rise is very dishonest, in my opinion. How much has the sea level risen in the last 20 years? Bugger all.

Rising sea levels - It is important to note that some places are sinking into the Earth's crust without rising sea levels. The New Orleans and Mississippi river delta is sinking as the weight of sediment builds up. During the ice age, there was much less sediment washed down the Mississippi. The weight of the sediment is pushing down into the crust and mantle. The sediment itself is also compressing slightly - when there's a 10 mile column of sediment, even a few parts per million works out to a few inches. Also, the earth's crust is tilted very slightly, so that New Orleans actually moves south each year, towards the Gulf of Mexico. Sliding into the ocean... In contrast, Miami, Florida does not seem to be sinking. The northern part of the Gulf Coast (west coast) of may be sinking toward the Gulf. Parts of Northen Europe are still rising - rebounding from the weight of the previous ice age. In the Baltic region, this is expected to be about one meter per 100 years.
