Canada’s vicious circle of extreme heat and wildfires

Summer has barely begun, and Canada has seen an unprecedented heatwave.

Lytton in British Columbia recorded the country's highest ever temperature last week, and though the current forecast is cooler it is still above average for the time of year.

The same area also saw devastating wildfires, thunderstorms and lightning.
