Bangkok 3.5 - 5 Feet Above Sea Level: Sinks 4 Inches/Yr Because Of Aquifer Pumping - AP

You do the math . . .

KHUN SAMUT CHIN, Thailand - At Bangkok's watery gates, Buddhist monks cling to a shrinking spit of land around their temple as they wage war against the relentlessly rising sea. During the monsoons at high tide, waves hurdle the breakwater of concrete pillars and the inner rock wall around the temple on a promontory in the Gulf of Thailand. Jutting above the waterline just ahead are remnants of a village that has already slipped beneath the sea.

Experts say these waters, aided by sinking land, threaten to submerge Thailand's sprawling capital of more than 10-million people within this century. Bangkok is one of 13 of the world's largest 20 cities at risk of being swamped as sea levels rise in coming decades, according to warnings at the recent Intergovernmental Panel on Climate Change held there. "This is what the future will look like in many places around the world," says Lisa Schipper, an American researcher on global warming, while visiting the temple. "Here is a living study in environmental change."

The loss of Bangkok would destroy the country's economic engine and a major hub for regional tourism. If the heart of Thailand is under water, everything will stop," says Smith Dharmasaroja, who chairs the government's Committee of National Disaster Warning Administration. "We don't have time to move our capital in the next 15-20 years. We have to protect our heart now, and it's almost too late."

The arithmetic gives Bangkok little cause for optimism. The still expanding megapolis rests about 31/2 to 5 feet above the nearby gulf, although some areas already lie below sea level. The gulf's waters have been rising by about a tenth of an inch a year, about the same as the world average, says Anond Snidvongs, a leading scientist in the field. But the city, built on clay rather than bedrock, has also been sinking at a far faster pace of up to 4 inches annually as its teeming population and factories pump some 2.5-million cubic tons of cheaply priced water, legally and illegally, out of its aquifers. This compacts the layers of clay and causes the land to sink.
