Things Global Warming Could Change Forever

London may disappear underwater by 2100

It isn't only reefs and low-lying islands that are under threat from global warming. In fact, a major threat is for those large urban areas which are at risk of eventually being submerged underwater. This is caused by a change in sea levels that occurs when global warming takes place, resulting in coastal cities being destroyed by flooding. Dozens of the world's cities, including London and New York, could be flooded by the end of the century, according to research which suggests that global warming will increase sea levels more rapidly than was previously thought. London is one of the major world capitals at high risk of this type of flooding, as depicted in this shot from the 2007 movie Flood. Scientists say that the city could be under water as early as within the next one hundred years.
