An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true, depending on local environmental conditions.

Smoke smudges Mexico City's air, chemists identify sources

Mexico City once topped lists of places with the worst air pollution in the world. Although efforts to curb emissions have improved the situation, tiny particles called aerosols still clog the air. Now, atmospheric scientists from UC San Diego and six other institutions have sorted through the pall that hangs over the city to precisely identify aerosols that make up the haze and chart daily patterns of changes to the mix.

Scientists to assess Beijing Olympics air pollution control efforts

As the Summer Olympics in Beijing kicks off tomorrow, the event is affording scientists at Scripps Institution of Oceanography, UC San Diego, a once-in-a-lifetime opportunity to observe how the atmosphere responds when a heavily populated region substantially curbs everyday industrial emissions.

Beijing’s Air Pollution Issue Is As Clear It’s The Skies

As the Olympic countdown reaches hours rather than days before kick-off, speculation about the weather condition become less abstract - will the pollution clear? - and more real - has it or not? However even now the issue of air pollution is a little hazy (apologies); conflicting stories seem and contrasting conditions seem to be stirring up debate.

Beijing Plan Ready To Control Pollution During Olympics

If you are living in the eastern United States, the environment around you is being harmed by air pollution. From Adirondack forests and Shenandoah streams to Appalachian wetlands and the Chesapeake Bay, a new report by the Cary Institute of Ecosystem Studies and The Nature Conservancy has found that air pollution is degrading every major ecosystem type in the northeastern and mid-Atlantic United States.
