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 effect of CO2
on ice (the former weakens the latter); — increasing, and increasingly 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 of the ice sheets where the base is below sea
level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)
New paper finds East Antarctic ice sheet will have negative contribution to sea
levels over next 200 years — Published The Cryosphere — Paper «studies one of the largest ice
shelves in East Antarctica and predicts increased accumulation of ice
on the
surface of the ice
shelf will have a net contribution of decreasing sea
levels over the 21st and 22nd centuries.
Increased ice - sheet flow can raise sea
level by shifting non-floating ice into icebergs or into floating - but - still - attached ice
shelves, which can melt both from beneath and
on the
surface.
