WMO Report Links Climate Change to Air Quality Deterioration

The World Meteorological Organization released a new report warning that rising pollution from wildfires and heat waves could jeopardise global air‑quality targets and the health of both people and ecosystems. The study maps how climate‑driven events intensify particulate matter and other pollutants, creating a feedback loop that undermines international agreements aimed at cleaner air.

According to the WMO, the frequency and severity of wildfires and heat waves have increased in recent decades, releasing large amounts of fine particles and greenhouse gases into the atmosphere. The report links these emissions to deteriorating air‑quality metrics in many regions, noting that the resulting smog and ozone can exceed WHO guideline levels and strain public‑health systems. It also highlights that the compounded effects of climate change and pollution threaten progress under frameworks such as the Paris Agreement and the WHO Global Action Plan on Air Pollution.

The findings underscore the need for coordinated climate‑and‑air‑quality policies. Strengthening fire‑management practices, reducing emissions from fossil‑fuel combustion, and enhancing monitoring networks are identified as critical steps to prevent a backslide in air‑quality improvements and to safeguard human and ecological health worldwide.
