Another face of climate change

"By 2050, it says, twice as many people could be displaced by conflict and natural disasters, but 250 million could be permanently displaced by climate change-related phenomena such as droughts, floods and hurricanes, and 645 million by dams and other development projects, based on a current rate of 15 million people a year. "The growing number of disasters and conflicts linked to future climate change will push the numbers far higher unless urgent action is taken. We estimate that between now and 2050 a total of 1 billion people will be displaced from their homes.""
