Greg and list (adding Peter Flynn) 1. Thanks for bringing this NOAA report to our attention. Clearly a worsening situation - especially in ice volume (as area/extent have to soon radically go to zero to follow the non-linear path of ice volume. Until today I hadn’t thought of anything new to add.
2. This is following up on the discussion many months ago of the idea broached by Prof. Peter Flynn of thickening the arctic ice by added layering from above with salt water ice flooding. (snow-making likely to not be as energy efficient) The only new thought is using moth-balled submarines from navies around the world (especially the US and Russia, who have the most - and we can use either active or mothballed). 3. I don’t expect lots of different navies to jump at this, but I think a test may be achievable from some navy - and we only need one. It seems to me this could/should be the cheapest approach to adding ice - with the sub moving every day or few days to a new spot, concentrating on those locations which are most likely to be salvageable with a small additional thickness. The experts seem to have a good handle on thicknesses. One sub isn’t enough, but there are probably a hundred if globally we really get scared of the total loss of arctic ice for even months on end. (I believe a “zero” area in September is likely in 2-3 years) 4. The main modification to the sub is for a low head high volume pump - a head of less than a meter generally, given the small percentage of the ice above water level. The size of one or more units has to be limited by the max sub (nuclear?) power output when stationary. 5. I have added Prof. Flynn to get his reaction. (And thank him also for his recent useful biomass paper sent to this list - with a later note coming on that).
