Hi All I agree with Doug about climate models. They sometimes disagree about the polarity of results. However the long life of stratospheric sulphur means that it spreads through an entire hemisphere and lasts for a year or two while the short life of tropospheric sea salt means that it is les

Whether one uses stratospheric aerosols or marine cloud brightening, it seems pretty safe to assume that lower temperatures at high latitudes will have a net benefit on both sea ice and SLR. Independent of CE, we have no useful capability to predict the most important part of SLR (that due t

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
