If the ice sheets began to advance southward I think I would consider a means of darkening the ice so it soaks up more sunlight. Its how I melt the ice off my sidewalk when I feel particularly lazy.
I throw out some black rubber mats and the ice under them melts in a couple hours even when it’s super cold.
In Colorado, they put coal dust on the roads instead of salt.
"They" have also claimed that China and India are putting out a cloud of soot that can be seen by satellites. The prevailing winds takes that black soot right over to the ice packs.
Before the epa started messing with internal combustion engines, good ol' Diesels could belch a big cloud of carbon black.. Maybe we should return to the days of high particulate diesel exhaust - we could collect the black and spread it on those pesky advancing glaciers... ;-)
It would be one way for Algore to use up his, umm, CARBON credits.
