Interestingly, there is a mention of geoengineering under "Arctic shrinkage", but it talks of a dam proposal as the only geoengineering approach focusing specifically on halting Arctic shrinkage, without mention of SRM (albedo engineering) as a general approach which could be employed to halt the shrinkage (as they put it). Nor do they mention other engineering ideas (e.g. from Albert Kallio): barriers to prevent ice flow into warmer waters, diverting Siberian rivers, blocking the Bering Strait, etc.
[quote] Alternative methods Perhaps other means are at hand to halt Arctic melting, for instance geoengineering approaches influencing local sea-ice albedo or ice dynamics. In September 2008[27] building the St. Lawrence Dam was proposed, a plan to influence temperature and salinity in the Arctic Ocean, favouring sea ice conditions. Up to date this seems to be the only publicly proposed geoengineering approach focusing specifically on halting Arctic shrinkage.

It then discusses carbon sequestration, seeding oceans with iron, and solar shades, all in a highly critical way. Most references are 2006 or before. It is no wonder that someone new to the subject will be sceptical. Here is an opportunity to get some facts into the public domain, and an update on opinion. We need a top level entry in the English version of wikipedia. Volunteers? Anybody experienced with getting a new wikipedia entry?
