Global warming disaster "imminent"

One of Britain's leading scientists warned last week that it might already be too late to prevent some of the world's most densely populated regions being drowned within a century by the sea level rise brought on by the burning of fossil fuels.
Southern China, Bangladesh and Egypt face massive loss of land and the spectre of millions of environmental refugees, Sir John Houghton, chairman of the Royal Commission on Environmental Pollution, told the Royal Society. In one of the most pessimistic updates yet on the likely impact of global warming, Sir John, chairman of the United Nations' Intergovernmental Panel on Climate Change and a professor of atmospheric physics at Oxford University, further warned that water supplies throughout the world would be severely affected.
Food supplies might not be affected by global warming. 'Some regions may be able to grow more, others less, but the distribution of production will change because of changing water availability. The regions likely to be adversely affected are those in developing countries in the sub-tropics with rapidly growing populations. There may be large numbers of environmental refugees.'
