Heat waves, wildfires to worsen air pollution – UN

GENEVA: More frequent and intense heat waves and wildfires driven by climate change are expected to worsen the quality of the air we breathe, harming human health and ecosystems, the UN warned Wednesday.

A new report from the UN's World Meteorological Organization (WMO) cautioned that the interaction between pollution and climate change would impact hundreds of millions of people over the coming century, and urged action to rein in the harm.
