Ozone Depletion

Pollutants Mucking With Food Production

24 May 2012

Two manmade pollutants known best as threats to human health have just been charged with two more offenses: shifting rainfall patterns and mucking with food production. Black carbon and tropospheric ozone, both of which derive from the incomplete burning of fossil fuels, may be working in cahoots with greenhouse gases to expand Earth's tropical belt (image).

Tropic Atmospheric Circulation

22 May 2012

An University of California - Riverside led team has identified black carbon and tropospheric ozone as the most likely drivers of large-scale atmospheric circulation change in the Northern Hemisphere tropics zone. While stratospheric ozone depletion has already been shown to be the primary driver of the expansion of the tropics in the Southern Hemisphere, the researchers are the first to report ...

Manmade pollutants 'may be behind Earth's expanding tropical belt'

17 May 2012

London, May 17 (ANI): Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low-to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, a new study has revealed.
