Heat Wave Scorches West, Breaking Records and Testing Resiliency

The West Coast is experiencing an unusual heat wave that is shattering temperature records and posing health risks.
Wildfires in western Canada fueled by record heat have caused air quality issues and evacuations.
Officials issued warnings and opened cooling centers as temperatures reached up to 30 degrees above normal.
The early heat wave came as a surprise but follows a deadly heat dome event last year that overwhelmed the region.
Climate change has made extreme heat events like this more likely and intense, according to scientists.
