Don't we know a good bit about the emergence from the last ice age?
In a book about the prehistory of Scotland "Beyond Scotland" it
mentioned that the sea level rose a meter or so (or was it a foot?) in
a few days, causing a good bit of havoc for the humans living along
the coast of the land bridge between Scotland and Europe. Due to an
ice dam failing or a meteor impact hiting Canada's glacier or
something. If we have archeological data about impact of sea level
rise on humans, then, with all the other potential data, I'd think we
might be able to map it out in time pretty well.
I wonder if there is evidence about albedo flip one way or the other
from the last ice age?
