Wildfires continue to burn across the western U.S. and Canada as firefighting crews struggle to contain the devastating blazes. Some 20,000 people in British Columbia were ordered to evacuate on Saturday as the massive Bald Range wildfire nearly doubled in size overnight near the regions of Summerland and Peachland. British Columbia’s premier said the fire was “like a bomb going off.” There are more than 100 active fires in the region, setting off a state of emergency. Scientists warn worsening heat waves and drought due to climate change has led to more frequent and intense fires worldwide.
