Stephen As I understand it SO2 gets rained out more readily than CFCs, which eventually drift into the stratosphere. CFCs are stable in the troposphere and only get destroyed in the stratosphere by the more intense UV.

Stephen I confess I'm not sufficiently familiar with atmospheric physics to say whether aerosol particles released under the Arctic stratosphere would substantially move up into it. Either way, Marine Cloud Brightening seems the safer option to me for the reasons you have given on numerous occasions. The question is if it can be ready in time and with sufficient social license. I think you're aware of the University of Washington's MCB work: https://faculty.washington.edu/robwood2/wordpress/?page_id=954 The video on that page is high quality and only about a month old. I wonder if some collaboration might help speed things up?
