Last week, after raging for two months over an area larger than Perth, the Fort McMurray fire was finally declared "under control" This was the costliest fire in Canadian history, forcing the relocation of 90,000 people -- the largest evacuation in Alberta's history -- and over $US2.9 billion ($3.7 billion) in losses. Although the fire is finally manageable, parts of the forest will likely burn for another year. Think about that: An entire year.
