Canada's Wildfires Ravage Northeastern Air Quality and Homes.

Early season wildfires in Nova Scotia, Canada, have caused the evacuation of thousands of residents and destroyed 200 homes. Smoke from the fires is spreading across the Northeast, causing diminished air quality and posing health risks for residents. Climate change is contributing to the increased risk of early season wildfires, as rising temperatures intensify dry spells. The Intergovernmental Panel on Climate Change has urged governments to cut greenhouse gas emissions to limit global warming. Most of the fires in Nova Scotia are likely human-caused, and the province has banned activity in wooded areas.
