World meteorologists point to ‘vicious cycle’ of heatwaves and air pollution.

Heatwaves across the world are worsening air quality and pollution,
scientists have said. The World Meteorological Organization (WMO) has said
extreme temperatures are not the only hazard from heatwaves but that they
also cause pollution-related health problems. In their annual air quality
and climate bulletin, the meteorologists have highlighted a “vicious
cycle” of climate breakdown and air pollution.

They have shown that
heatwaves sparked wildfires in the north-western US and heatwaves
accompanied by desert dust intrusions across Europe, which both caused
dangerous air quality in 2022. The hot temperatures in Europe, which in
2022 were record-breaking, led to higher levels of particulate matter in
the air, the bulletin says. During the second half of August 2022, there
was also an unusually high intrusion of desert dust over the Mediterranean
and Europe.
