BBC NEWS Science/Nature Tuvalu struggles to hold back tide
http://news.bbc.co.uk/2/hi/sci...
During a King Tide, which is what the islanders call the highest tides of the year, waves rolling off the ocean can have a devastating effect.
"As sea levels rise, low lying island nations like Tuvalu are fast becoming uninhabitable. Just building walls to hold back the sea is not enough. Tuvalu’s coral laden soil is quite porous, which allows sea water to seep into low lying areas all over the islands, contaminating both water supplies and arable land. So, while it may continue to be physically possible to live on the islands for many decades, the economic viability of the state is already under severe threat."
