Holly and List, The use of sulfur needs proper polar field level testing. Testing is planned yet may not be done in areas prone to Polar Stratospheric Cloud formation. Time of the season is also of the essence for testing. Until that is done, SAI has a large question to answer; in general term

Hi All My suggestion is based on the idea that more precipitation and lower temperature will produce more ice. With marine cloud brightening in the troposphere we have some control of where this will form. I think that the papers Holly mentions may have been about stratospheric sulphur. Steph

Hi, It would be very helpful if someone could weigh in on what the latest research on CE and SLR actually indicates. It seems as if early research on sunshade geoengineering found it promising for reducing ice melt. - But as Applegate and Keller (2015) wrote, with regards to Greenland, th

Andrew Do marine cloud brightening near but not too close to polar and Greenland ice during the months either side of mid summer. Evaporation from the sea at mid latitudes will provide precipitation to increase polar ice depth which will be retained by the lower temperatures. Adjust the amoun
