A peer-reviewed study published in Science Advances found that fire-conducive conditions across North America have increased 36% since the 1970s, with northern regions seeing 232% more days of round-the-clock burning. Warmer nighttime temperatures are eroding the traditional overnight lull that firefighters depend on to suppress wildfires, meaning fires no longer slow down at night and crews have fewer breaks to mount defense efforts. Canada is warming twice as fast as the global average, accelerating this shift, and Alberta and British Columbia have already expanded night-vision firefighting capabilities to address the changing fire dynamics.
