US - good neighbours, bad air

Wildfire season started early this year out West.

Thousands of people were evacuated from their homes in Alberta and British Columbia in May.

Experts say above-average temperatures and drought-like conditions could put us on track for another summer of extreme wildfires.

It’s terrifying for people living in the path of the flames.

And it’s unhealthy for everyone who breathes in the massive clouds of smoke produced by tens of thousands of square kilometers of burning forests and brush.

Just like last year, that includes our neighbours south of the border.

On this episode, I'm joined by Professor Owen Temby, an expert on bad air in North America, to look at the US reaction to our wildfire smoke, as our pollution becomes their problem.
