Coastal Regions
Global sea level is currently rising due to the thermal expansion of water in the oceans and the addition of water from ice sheets. Because of this, there low-lying coastal areas, many of which are heavily populated, are at risk of flooding.
Areas threatened by current sea level rise include Tuvalu and the Maldives. Regions that are prone to storm surges, such as London, are also threatened.
With very high confidence, IPCC (2007) projected that by the 2080s, many millions more people would experience floods every year due to sea level rise. The numbers affected were projected to be largest in the densely populated and low-lying megadeltas of Asia and Africa. Small islands were judged to be especially vulnerable.

Famous quotes containing the word regions:
“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
