WMO Urges Continued Air Quality Efforts

The World Meteorological Organization indicates that the increasing occurrence of wildfires and heatwaves is hindering efforts to improve air quality and protect human health. Wildfires have become a growing source of harmful air pollution. The report explains that particles produced by these fires, particularly PM2.5 and ozone, damage the respiratory system and the heart, with their concentrations rising in areas such as northern Canada, Russia, and Spain due to the frequency of fires. Studies have also shown that episodes of heavy smoke have tripled since the 1990s, potentially causing around 100,000 additional deaths annually between 2010 and 2018, alongside the increasing heatwaves and wildfires driven by rising global temperatures.
