Human displacement around the world in 2012 was caused largely by natural catastrophes and climate change, with displacement from Hurricane Sandy ranking No. 3 among such events last year, according to a report from the Internal Displacement Monitoring Centre. "The USA was among the ten countries worldwide with the highest displacement levels in 2012. Months before Hurricane Sandy, Hurricane Isaac displaced 60,000 people in August. ... Widespread forest fires forced over 39,000 people to evacuate their homes," according to the report.
