*Folks, I forward this email sent to "Climate Intervention" to "Geoengineering" mostly because it seems aimed at a broad audience.
**Best, Ken * --------------- Hi All, Anyone who has some interest in a geoengineering project that would use a ship (ice breaker) as its platform get in touch (or who acts as a sponsor), I will try to check out what could be done. Would some projects be better to do with a barge or another platform jutted into sea ice and then serviced by our ice breaker. Its 50 metre with helipad. Note that we have funding in place for the ship, but we seek more funds to secure its sustained operation for 5 years minimum before proceeeding, also need to let know what project you want to do. Please drop just a brief line so that I could see the idea, cost and any specific requirements you have so that we could check it out if workable. Our ice breaker could also support land and sea ice based bases for experiments.

If the 2007 trend, shown below to be well outside the IPCC worst case, is repeated there may be an official panic and we should plan now for a response to headless chickens. > > Under 'peacetime' conditions we think that cloud albedo modification using a fleet of ships could be done in about five years. On the basis of Twomey's results and the Bennartz figure for initial drop concentration, a fleet of 50 ships operating in water flowing towards the Arctic in the Atlantic drift between Iceland and Norway could remove an amount of heat comparable with the latent heat of fusion of a year's missing ice in about six months. > > Up to now we have been hesitant about spray release from land because of the need for annual migration and anxiety about additional CCN from dusty beaches. But perhaps we should reconsider this for the special case of the Arctic. The Faroe islands are in the middle of the water flow and are some distance from dirty air in the North Atlantic shipping lanes. They are soggy rather than dusty. Depending on wind directions we could also look at sites on Shetland, the outer Hebrides, Norway and the east coast of Iceland and maybe even Bear Island. Even though the release points are static the change in wind direction should move salt residues around.

This is all too much for a greasy-fingered mechanic.
