What is the Future of Air Pollution Globally?


Effects of business-as-usual anthropogenic emissions on air quality(23 page pdf, A. Pozzer, P. Zimmermann, U.M. Doering, J. van Aardenne, H. Tost, F. Dentener, G. Janssens-Maenhout and J. Lelieveld, Journal of Atmospheric Chemistry and Physics, Aug. 1, 2012)

Today we review a paper that looks at the state of air quality globally for the next 40 years, using an index that represents the five major pollutants and a global circulation model to produce scenarios into the future if we continue with “business as usual” policies. These scenarios show that countries and large cities with the worst widespread pollution (in Indo-Asia, the Middle East and North Africa) will not surprisingly deteriorate. The rest of the world’s state of pollution will worsen on average to what we see today in East Asia with the negative health results and enhanced anthropogenic climate change that this implies. Clearly improved atmospheric environmental policy is called for in almost all countries.
