Abstract: | Analytical solutions of globally averaged energy-balance model to estimate the efficiency of controlled forcing on the climate
in the result of sulfate aerosol emissions into the stratosphere are obtained. According to obtained results, the sulfate
aerosol emissions, needed to prevent the warming, make up from 2 to 12 Mt S/year in the end of the 21st century depending
on the anthropogenic impact scenario and aerosol parameters. In the case of the cessation of such compensative emissions of
sulfate aerosols, the global temperature increase rate may reach 3 K per decade, that is several times more than values, derived
when taking account of greenhouse effect only. |
