Argument: Sulphate solar shading may increase cloud cover
Alan Robock. "20 reasons why geoengineering may be a bad idea". Bulletin of the Atomic Scientist. 2008: 6. Effects of cirrus clouds. As aerosol particles injected into the stratosphere fall to Earth, they may seed cirrus cloud formations in the troposphere.11 Cirrus clouds affect Earth’s radiative balance of incoming and outgoing heat, although the amplitude and even direction of the effects are not well understood. While evidence exists that some volcanic aerosols form cirrus clouds, the global effect has not been quantified.
