The World Air Quality Report 2023

IQAir has released its annual World Air Quality Report. The 2023 report reveals that last year only seven countries met the World Health Organizations' PM2.5 air pollution guideline.

The IQAir Annual World Air Quality Report is a yearly analysis of global air quality, compiled by the Swiss air quality monitoring firm IQAir. The report gathers data on PM2.5 (which is particulate matter with a diameter of 2.5 micrometers or less) from thousands of ground-based monitors around the world. This data is then used to assess air quality on a national and regional level.

The IQAir website features an interactive map alongside the 2023 report. This map allows you to explore the annual PM2.5 levels in 7,812 cities around the world. The map also shows how each city ranks globally compared to all the other analyzed cities. For example New York had the 2,627th worst air pollution last year with an average PM2.5 level of 11.6 (the WHO guideline is a PM2.5 level of 5).

The seven countries who met the WHO PM2.5 air pollution guideline were Australia, Estonia, Finland, Grenada, Iceland, Mauritius, and New Zealand. The top five most polluted countries in 2023 were Bangladesh (with an annual PM2.5 level more than 15 times higher than the WHO annual guideline), Bangladesh, India, Tajikistan and Burkina Faso. The report also revealed that in 2023 for the first time Canada had the worst air pollution in North America (largely due to the increased number of wildfires).

Canada's fires have nothing to do with our air quality. It has to to with our G O V E R MENT spraying chemicals from planes across the country daily.

Do you really believe that smoke doesn't impact air quality?

Anonymous is a CT enthusiast, I see. Chemtrails don't exist - but smoke from fires does. And it travels.
