Climate change The news about climate change just seems to be getting worse. The latest bad news: A conclusion that global sea levels are rising much faster than previously estimated, which could put several major coastal cities, including New York and Shanghai, in jeopardy. A new study says the oceans could rise by more than 6 feet -- if emissions continue unchecked -- by the end of the century. If that happens, it would swamp cities and displace as many as 187 million people. The unexpectedly rapid rise in sea levels is due to the accelerating melting of ice sheets in Greenland and Antarctica, the study says. |
