Heatwaves and wildfires to worsen air pollution: UN

14 Sept 01:45 Key points summarised by AI
  • Climate change-driven heatwaves and wildfires are projected to severely degrade air quality, posing significant risks to human health and ecosystems.
  • The UN's WMO report reveals that large wildfires, like those in Siberia and North America in 2021, produced unprecedented levels of harmful fine particulate matter (PM2.5).
  • Beyond wildfires, hotter climates worsen air quality by increasing ground-level ozone through a 'climate penalty' effect, with Asia expected to bear a significant impact.
  • The WMO stresses the interconnectedness of air quality and climate change, urging global action towards carbon neutrality to limit future extreme air pollution episodes.
