Indian coasts vulnerable to global warming: study

Of more than 180 countries with populations in the low-elevation coastal zone, about 70 per cent have urban areas of more than 5 million people that extend into it, including Mumbai, Tokyo and New York.

Asia is particularly vulnerable and in general poorer nations are most at risk, the peer-reviewed scientific study. In all, 634 million people live within such areas 8212; defined as less than 10 meters 33 feet above sea level 8212; and that number is growing, said the study released on Wednesday. It does not say exactly what should be done, but it warns that it won8217;t be cheap and it may involve moving lots of people and building protective engineering structures.
