Asian Mega-cities to get Swallowed by Sea
21 "mega-cities" of 8 million people or more around the world are facing the danger of rising seas and other disasters related to climate change.
The nonprofit Worldwatch Institute has released a list of 33 cities predicted to have at least 8 million people by 2015, at least 21 are highly likely in direct danger as a result of global warming and rising seas.
The nonprofit Worldwatch Institute has released a list of 33 cities predicted to have at least 8 million people by 2015, at least 21 are highly likely in direct danger as a result of global warming and rising seas.
They include Dhaka, Bangladesh; Buenos Aires, Argentina; Rio de Janeiro, Brazil; Shanghai and Tianjin in China; Alexandria and Cairo in Egypt; Mumbai and Kolkata in India; Jakarta, Indonesia; Tokyo and Osaka-Kobe in Japan; Lagos, Nigeria; Karachi, Pakistan; Bangkok, Thailand, and New York and Los Angeles in the United States, according to studies by the United Nations and others.
More than one-tenth of the world's population, or 643 million people, live in low-lying areas at risk from climate change, say U.S. and European experts. Most imperiled, in descending order, are China, India, Bangladesh, Vietnam, Indonesia, Japan, Egypt, the U.S., Thailand and the Philippines.

Sea-level has risen about 130 metres (400 feet) since the peak of the last ice age about 18,000 years ago. Most of the rise occurred before 6,000 years ago. From 3,000 years ago to the start of the 19th century sea level was almost constant, rising at 0.1 to 0.2 mm/yr. Since 1900 the level has risen at 1 to 2 mm/yr; since 1993 satellite altimetry from TOPEX/Poseidon indicates a rate of rise of 3.1 ± 0.7 mm yr–1. It is very likely that 20th century warming has contributed significantly to the observed sea-level rise, through thermal expansion of sea water and widespread loss of land ice. Church and White (2006) found a sea-level rise from January 1870 to December 2004 of 195 mm, a 20th century rate of sea-level rise of 1.7 ±0.3 mm per yr and a significant acceleration of sea-level rise of 0.013 ± 0.006 mm per year per yr. If this acceleration remains constant, then the 1990 to 2100 rise would range from 280 to 340 mm. Sea-level rise can be a product of global warming through two main processes: expansion of sea water as the oceans warm, and melting of ice over land. Global warming is predicted to cause significant rises in sea level over the course of the twenty-first century.
