The Bangladesh delta: rising sea levels are changing the salinity of its water
There's an interesting photo essay on the rapidly disappearing town of Shishmaref on the ABC News Web site. The coastal Alaskan village has about 600 residents and is believed to have been inhabited (on and off) for 4,000 years. Today, with water rising about 10 feet a year,* it's in danger of sinking. The population of Shishmaref may soon count themselves among the first wave of global-warming refugees.
As the effects of climate change worsen, there will be more Shishmarefs. Already there are places similarly adjusting—not just to a single awful hurricane or several bad droughts, but to a new pattern. Munshiganj, Bangladesh, is one such place. In the midst of a delta surrounded by rising seawater, the farmers in the Munshiganj district are seeing their livelihood die before them. Saltwater seeps into the groundwater, drinking water is growing scarce, rice paddies are dying out, and shrimp farming has become the new major industry. Der Spiegel has a striking slideshow.
While most of us haven’t voluntarily changed our lifestyle, the residents of these areas have been forcibly made to do so. It seems only a matter of time before this becomes the rule rather than the exception.—Abby Seiff
*As many have noted below, this was poor word choice on my part. Water rises up Shishmaref's coast at a rate of about 10 feet a year. This is due to a variety of factors including melting sea ice and permafrost—both of which have weakened the coastline. The sea level does not rise at that rate.—A.S.

How or why is this linked with global warming? It seems to me that this has nothing to do with global warming but a piece of land that is sinking into the ocean due to subsidence.
So the title of this SHOULD BE, a village adjusting to subsidence.
0 out of 0 people found this comment helpfulDo you mean that the sea level at this village is rising 10 feet a year? Surely that cannot be the case. Is there instead a contained body of water that is rising 10 feet a year? If so, I'd be interested in the name of that body of water and the sources it has for such an alarming increase at that particular latitude. As for Bangladesh, if I recall the recent history of that particular part of that continent well, it seems that it is pretty much always at or about sea level. I believe it is primarily the Delta of the Ganges and two other rivers. Monsoons, tides, and other weather cycles seem to have had their way with Bangladesh for a long, long time. So you seem to have one place on the planet where the sea level has risen 10 feet and another place where if the sea has risen 3 feet most of the land goes underwater. Does water in the ocean still, generally, seek its own level, or has that property of water been rescinded?

Otherwise, you're making yourself look foolish by printing such ridiculous nonsense about the world's oceans.

Abby, please reread that sentence and realize how utterly illogical it is.
" The population of Shishmaref may soon count themselves among the first wave of global-warming refugees."
I know it has been asked above, but I'll ask again; what in the name of God does subsidence have to do with global warming?

This is part and parcel with the dominance of editors from the liberal arts. Just as a few months ago SI had a baseball cover depicting this kinda thing.
Idiots playing at Science. I shiver for the future.

See http://www.nola.com/timespic/stories/index.ssf?/base/library-121/1172887... for more details on the imminent washing away of New Orleans, levee or no levee, global warming or no global warming.
