Canadian wildfires never caused US skies to turn orange in the past. Here’s what changed

Wildfires in Canada have blanketed parts of the U.S. in smoke, leading to unprecedented air quality issues, including reports of orange skies in areas usually unaffected by such events. This shift is largely due to changes in weather patterns and increased fire activity, likely exacerbated by climate change. Historically, these fires have not reached the U.S. in such dense volumes, highlighting the growing impact of global warming on regional weather and environmental conditions. This situation underscores the urgent need for stronger climate action and cross-border environmental cooperation.
