This map viewer illustrates the scale of potential coastal flooding after varying amounts of sea level rise. The worst lasted from about 1560-1600, 1750-1800 and 1830-1860. To the naked eye, the signs of climate change are almost imperceptible, but government scientists fear the sea level is rising up to 0.9cm a year. However, the authors warned that their findings also apply to islands all over the world including the Maldives, Seychelles and parts of Hawaii – meaning hundreds of thousands of people could be driven from their homes. In many parts of the world, glaciers have been in retreat, creating dangerously large lakes that can cause devastating flooding when the banks break. They then looked at data from the rings of ancient trees that researchers sampled at 28 sites in Tibet, Myanmar, Nepal and Bhutan, at sites within the Brahmaputra watershed, or close enough to be affected by the same weather systems. The Brahmaputra is one of the world's mightiest rivers, flowing under a variety of names and braided routes some 2,900 miles through Tibet, northeast India and Bangladesh.
