Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct

warm, rain fall on ice; — «stuck» weather systems bringing more and more
warm tropical air ever further toward the poles; — melting
of sea ice shelf increasing mobility
of glaciers; — sea water getting under parts
