Global warming could put three of India's biggest cities?Bombay, Calcutta and Madras?under water by 2020. There's evidence it's happened before: an ancient underwater city has been discovered there. It could also happen to us?if the ice caps melt, London, New York, Miami, Sydney, Shanghai and Tokyo could all end up under water.
Geoffrey Lean writes in the Independent about a German study that says the rate of climate change will soon exceed anything that's happened "in the last million years." If nothing changes, the West Antarctic ice sheet and the Greenland ice cap will begin to disappear, leading to sea levels rises which will submerge many coastal cities.
Oceanographer Rajiv Nigam says, "If the warming continues, there will be about a [1 ? to 3 foot] increase in sea level by 2020 and cities like Bombay, Calcutta and Madras will be completely submerged."
Major cities may have been submerged in the past. Utpal Parashar writes in the Hindustan Times about the discovery of an underwater city in Tamil Nadu, India, which some archeologists think may be older than Sumeria in Mesopotamia, where modern civilization probably originated 5,000 years ago. K.R. Srinivasan says, "We have been able to locate a section of the city at a depth of [23 feet] and will soon start operations to recover objects that will help ascertain its past."
