🔥 From record wildfire emissions in Europe to large-scale wildfires in Canada, California and around the Mediterranean, #CopernicusAtmosphere data show how wildfires throughout 2025 degraded air quality far beyond where the fires burn.

Have you seen our overview of the 2025 wildfire season?

Data from #CopernicusAtmosphere shows how record emissions in Europe and major wildfires in the Northern Hemisphere sent smoke and pollution far beyond the fire zones, degrading air quality across continents.
