Recent changes in the Earth's climate have led to extreme weather conditions. Natural disasters such as hurricanes, tornadoes, heat waves and floods occur more and more often and are more unpredictable than before.
The effects of Alberta's catastrophic flooding in June 2013, which killed five people and displaced 100,000 in 48 hours.
In the past two decades, hurricanes along the North American coastline have grown more powerful and destructive; in 2016, Hurricane Matthew wreaks havoc across the continent, decimating parts of the Caribbean before bearing down on the Florida coast.
