TODAY IS International Day of Clean Air.




99% of our world is exposed to polluted air causing an estimated 7 million premature deaths every year.
On this International Day of Clean Air for blue skies, on 7 September, WHO/Europe recognizes the value of “the air we share” and the need for a concerted cooperative effort to tackle the persisting burden of air pollution that is driving climate change and damaging people's health.

On November 26, 2019, the Second Committee of the 74th session of the United Nations (UN) General Assembly adopted a resolution designating 7 September as the “International Day of Clean Air for blue skies”

The theme of the third annual International Day of Clean Air for blue skies, facilitated by the United Nations Environment Programme, is “The Air We Share.”

Air pollution, exposure to lead and other chemicals, and hazardous wastes including exposure to improper e-waste disposal, cause debilitating and fatal illnesses, create harmful living conditions, and destroy ecosystems.

    Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth's temperature,” Walke says


Clean, dry air consists primarily of nitrogen and oxygen—78 percent and 21 percent respectively, by volume. The remaining 1 percent is a mixture of other gases, mostly argon (0.9 percent), along with trace (very small) amounts of carbon dioxide, methane, hydrogen, helium, and more.

Sunshine, rain, higher temperatures, wind speed, air turbulence, and mixing depths all affect pollutant concentrations. National Weather Service provides model forecast guidance for ozone, dust and fine particulate matter twice daily and smoke predictions once daily for next 48 hours.
