Ken But if sulphate aerosols spread to lower levels would they not act as cloud condensation nuclei and so form a blanket of drop large enought to reflect the long waves? Stephen Ken Caldeira wrote: If we are talking about Latham's proposal, there would be no reason to make clouds in

Folks, One of the big selling points of Stratospheric Aerosol Injection was that it had a real world example, Pinatubo. Let's use that advantage and look closely at the *Winter* time data 5 yrs before and 5 years after. I personally am not comfortable with accepting a casual discounting of the

To what degree of likely are we talking about? Also, would there be issues with clumping which could create condensed areas within the SRM layer which could mimic PSC? Further, will the SRM particles *augment*PSC's warming ability when the 2 mix? The fact that the IR energy will be coming in
