I'm glad we agree. Small cloud seeding experiments over Greenland should be practical. We should give this some thought and modeling. Can you do that at your lab? Google satellite pictures and weather satellites can locate clouds that are likely targets to seed; The bigger clouds in the places that are most strategic. An international organization or groups of industrialized nations can pay the local residents or the greenland government subsidies for participating in the cloud seeding program.
