A good dump of late spring snow could do quite a bit to help retain permafrost, too. There would be both an albedo and a thermal insulation effect.
The effect would be more marked, although more temporary, than inducing snow over permanent ice cover. I'm really surprised this hasn't been.mentioned before, as it's pretty simple (unless I'm missing something) A On Dec 4, 2012 3:08 PM, "Charlie Zender" <[email protected]> wrote: > Hi Andrew, > I assume your goal in cloud seeding would be to brighten not darken the > surface to cool climate.
