The historic rise of carbon dioxide levels above 400 parts per million in the atmosphere has many people thinking about climate change’s Brobdingnagian impacts. And right on cue, new research indicates that huge numbers of people, animals, and plants can expect to find themselves ejected from their homes because of global warming over the coming years and decades.
An estimated 32.4 million people were forced to flee their homes last year because of disasters such as floods and storms, according to a new report released by the Internal Displacement Monitoring Centre -- and 98 percent of that displacement can be blamed on climate- and weather-related events. That includes not just people in poor countries but also many Americans displaced by Hurricane Sandy and other disasters.
Also picking up the homeless theme is Lord Nicholas Stern, a British economist famous for a groundbreaking 2006 report on the costs of climate change. He warns that hundreds of millions of people will likely be displaced in the near future. From The Guardian:
