Climate change blame

Who's to blame is another contentious topic.
Residents of the industrialized world could be considered liable for the climate refugee problem, since they produce the bulk of the greenhouse gas emissions that alter the climate. Some say the government is responsible. Others say it's difficult to prove with absolute certainty that a problem in any single community was caused by climate change because other factors, like land use and natural erosion, could be at play.

The climate refugee problem gets all the more complicated when considered on a global scale. The Environmental Justice Foundation estimates that unchecked climate change will force 150 million people from their homes by mid-century.
