Raising dust in the greenhouse

Article Abstract:

Over-cultivation, deforestation, and soil-erosion in arid and subarid regions have increased the amount of dust in the atmosphere and raised the global temperature. Dust aerosols play a major role in the global radiation changes. The variable effects of aerosol change the energy input to the climate and cause an uneven distribution of warming and cooling effects. Very little documentation is available about atmospheric aerosol and studies have been unable to prove that atmospheric aerosol has increased since the onset of the industrial age.

Strong present-day aerosol cooling implies a hot future

Article Abstract:

Aerosols' much shorter lifetime and the pursuit of a cleaner atmosphere will lead to declination in aerosol cooling. Strong aerosol cooling in the past and present implies that future global warming may proceed at or even above the upper extreme of the range projected by the Intergovernmental Panel on Climate Change.
