Included in these aerosols are large amounts of hydrogen chloride (HCl). Some scientists argue that the amount of chlorine put into the ... the chlorine from the plume reaches the stratosphere. The general conclusion is that volcanically-produced sulfate aerosols have a destructive effect on ozone, but that volcanically-produced chlorine is of minor ...

The Regional Impacts of Climate Change
C increase during 1901-96 in the region as a whole (see Annex A, Figure A-9). Climate models that include the effects of sulfate aerosols (GFDL and CCC) (IPCC 1996, WG I, Figure 6.7) project that the temperature in the region will increase 1-2C by 2030-2050. The greatest increases are projected for winter in the northeast and for summer in part ...

Climate Change
These increases have enhanced the heat-trapping capability of the earth’s atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space; however, sulfates are short-lived in the atmosphere and vary regionally. Why are greenhouse gas ...

Climatology
Earth. Aerosols effect climate. Natural examples of aerosols are pollen and salt crystals from windblown seawater. Soot and sulfates from ... heating when it lands on snow. Aerosols block some sunlight and thus cause surface cooling. Sulfate aerosols are highly reflective which leads to cooling. Aerosols can have a strong effect on ...

Patrick Michaels Reviews Hansen's Global Warming Forecasts
Mr. Hansen in a 1990 paper, was that the warming was being moderated by sulfate aerosols, another result of fossil fuel combustion that whitens the sky and reflects away the sun's ... In 1996 my colleague Chip Knappenberger and I noted in Nature that the sulfate hypothesis doesn't hold up because the sulfate-free regions of the planet have actually cooled in the last decade, ...

Extremism in pursuit of green
The currently fashionable explanation is that the warming is being "hidden" by other industrial compounds, namely finely divided sulfate aerosols that screen the sun and brighten the clouds. They are almost exclusively found in the industrial Northern Hemisphere and they rain out before they head south of the equator. Obviously, the fashionable explanation is ...
