Fighting Fire

Available for over a year

When wildfires engulfed the Canadian city of Fort McMurray last May 90,000 people were displaced and well over £2bn of damage was caused, making it one of the costliest natural disasters of all time. That fire proved to be just the start of a summer of flames that ripped through California, Greece and France. An area the size of India now burns every year and climate change is blamed for an increase in the length of the fire season across the boreal forests of North America. Tom Heap visits Fort McMurray to find out how a city could be so easily engulfed by fire and to meet the local scientists and firefighters working out fresh strategies to make sure it doesn't happen again.
