Dear Renaud

Thank you for sending me the Stjern et al. multi-model ensemble of marine cloud brightening.

I found figure 4d very encouraging.  The big reductions of precipitation are mainly over equatorial oceans and there are valuable increases in drought-stricken land regions. I once did some work on desalination driven by wave energy and we could easily provide compensation for dry islands.

I understand that that the G4cdnc experiments treats all clouds all the year. Perhaps by cherry-picking times and seasons with regard to monsoons, El Niño and day-to-day observations we could do even better and get a win-win result for the great majority.

It would be useful to compare the scatter between separate runs of each model with its mean and also the mean of the entire group but this might embarrass the outliers.

Best wishes

Stephen
