[Aerosol] Cutting air pollution in cities may raise global temps, says scientist

"Hans-Joachim Schellnhuber, director of the Potsdam Institute for Climate Research, warns that cleaning air in Beijing and in other large cities suffering from pollution problems by limiting car and power-plant emissions may raise global temperatures instead of lowering them. He also said a drop of aerosols, which have a cooling effect on the Earth, could cause a "rapid" rise in temperatures. A rise in temperature because of declines in aerosols in the atmosphere can be offset by slashing CO2 emmissions"

Is this true ?
Symply, aerosols can reflect incomming solar radiation and cool the earth's surface. However absorbing aerosols, such as black carbon or dust, can absorb solar radiation, which leads to heating of atmosphere. His argue is irony becuse over the large meagacities, mainly urban polluted aerosols are composed of these absorbing particles.
