9. Extreme Weather Events

This is another category that made the top 10 in North America and East Asia/Pacific, but not in other regions.

"Extreme weather has plagued the region once again this year, as many Canadians confronted 'polar vortex' temperatures and one of the snowiest Januaries on record, while the coasts experienced unusually moderate weather," the report said.
