There is a good paper in Nature on the differing cooling effects of particulate emissions at different places in the world, and it does lead to the idea of focused albedo increases over the polar regions in the May-July period as an effective way of cooling.

There have been proposals, Variously to: *break up winter ice *spread shiny minerals on the ice *tether icebergs *mix fibres with ice to increase strength *restrain water flows with floating dams *buttress glaciers with rock piles *seed glaciers, or change their albedo *clear boreal forests to restore tundra *paint cities white A On Mon, 22 Oct 2018, 14:05 Kevin Lister, <kevin.lister2...@gmail.com> wrote: That is the essence of solar radiation management.

Could floating reflective material be used to mimic the formerly larger ice sheets at the north pole (and maybe the south, if those ice sheets continue falling away)? In other words, could we geo-engineer reflection fields that mimic the reflection that was occurring in the late 19th / early 20th century, before we so significantly increased our use of fossil fuels? -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
