Wildfire season is here. During each of the past two summers a thick blanket of smoke from wildfires covered large parts of Western Washington. Thousands of wildfires in the American West and Canada burned millions of acres. UW Tacoma Assistant Professor Maureen Kennedy talks about how climate change has contributed to a prolonged fire season. She'll also talk about the role of fire in forests and how fire suppression practices that were created to protect forests lead to larger and more destructive wildfires.
