US EditionWildfires Producing 'Witches' Brew' of Air Pollution
Wildfires in Canada and agricultural biomass burning in South Asia contribute to rising air pollution globally despite improvements in some regions, the World Meteorological Organization said.
- Wildfires in Canada sent smoke and pollutants reaching Europe, creating a 'witches' brew' that can severely degrade air quality far from the fires, the United Nations World Meteorological Organization warned.
- The WMO said the Indo‑Gangetic Plain, home to more than 900 million people, saw rising pollution and longer winter fog linked to agricultural biomass burning, urging improved monitoring and policies.
- Data show PM2.5 declines in eastern China last year due to sustained mitigation, while the World Health Organization estimates air pollution causes more than 4.5 million premature deaths annually.
- The WMO warned wildfire seasons grow stronger and longer due to climate change, causing air pollution to cross borders and worsen quality for millions amid shifting meteorological conditions.
- Paolo Laj noted when measures are enacted, Chinese cities have dramatically improved air quality over a 10-year period, showing clear meteorological improvements.

Africa: Air Pollution Is On the Rise - but Not Everywhere, Says UN Weather Agency
As billions continue to breathe polluted air that causes more than 4.5 million premature deaths every year, UN climate experts on Friday highlighted how damaging microscopic smoke particles from wildfires play their part, travelling halfway across the world.
UN weather body links rising wildfires to worsening global air pollution
Wildfires likely to have been made more frequent by climate change made significant contributions to air pollution last year, according to a report by the World Meteorological Organization (WMO) on Friday. The World Health Organization says ambient air pollution causes 4.5 million premature deaths a year, and the WMO report for 2024 pointed to pollution hotspots in places that experienced intense fires such as the Amazon basin, Canada, Siberia a…
