The pace of ice loss — both its extent and the amount of the older, thicker ice that survives from summer to summer — has been faster than most models predicted and clearly has, as a result, unnerved some polar researchers by revealing how much is unknown
about ice behavior in a warming climate.

«Incorporating all of these uncertainties is daunting, largely because of the computational challenges involved,» and to an extent, «whatever we say
about the
behavior of
ice sheets in the future is necessarily imperfect,» note the authors.
But our understanding of the
ice sheet's complex
behavior before
about 125,000 years ago has been fragmentary at best.
We still don't know enough
about tar sand oil, or bitumen, which takes longer to break down due to its high viscosity, but doesn't spread, we also don't know much
about the
behavior of oil from a blowout, such as the Deepwater Horizon BP blowout, and we know little of how crude oil behaves in the Arctic Ocean, where there is
ice, or how to remediate it,» said Michel Boufadel, director of NJIT's Center for Natural Resources Development and Protection and a member of the panel of experts charged with evaluating the impact of spills in Northern waters.
The findings, published yesterday in the journal Science, suggest scientists still have much to learn
about the factors that govern the
behavior of
ice sheets — knowledge that is crucial to developing more accurate projections of future sea level rise.
Lack of knowledge
about the
ice sheets and their
behavior is the primary reason that projections of global sea level rise includes such a wide range of plausible future conditions.
But polar scientists say there is still much to learn
about what drives the
behavior of Antarctic sea
ice, which is quite different than its Arctic cousin.
This in turn will provide a means to answer critical questions
about the
ice sheet's
behavior in a warming world.
GPS and seismic measurements together provide a means to answer critical questions
about ice sheet
behavior in a warming world.
The
Ice Truck Killer kidnaps someone close to Dexter, forcing him into a trap that will forever change his life, while Doakes begins to harbor suspicions
about Dexter's odd
behavior.
Learn
about the
behavior of glaciers and hike with professional mountain guides on the Solheimajökull glacial tongue, a wonderland of
ice sculptures, water cauldrons, ridges, and deep crevasses.
I guess I would say that the longest term extrapolation is
about 30 years for the September sea
ice behavior,
about as long as the data set.
tested against the observed
behavior of the
ice and the usual assumptions
about the future of the climate in the Greenland region over the coming decades, comprise the pieces of the puzzle needed to come up with an estimate of how fast things are really proceeding in Greenland.

Ice Data Center has inaugurated a useful new Web feature, Icelights, that offers the public a two - way portal for addressing questions
about the
behavior of sea
ice and ice sheets and their relationship to the world far from the pol
ice and
ice sheets and their relationship to the world far from the pol
ice sheets and their relationship to the world far from the poles.
It's a bet
about as ill advised (to propose or accept) as the dicey
behavior of this Russian worker when I spent time on the sea
ice near the North Pole in 2003:
And it also explains why I won't take a 50/50 bet
about Arctic
ice behavior in nine years, even while I will advocate for a transition to an energy menu that works for the long haul.
We have a pretty good idea that the Heinrich events, with the most prominent bipolar seesaw
behavior, are linked to
ice - sheet
behavior, but we're less confident
about the non-Heinrich cold phases of the D / O oscillations (the cold phases do have more
ice - rafted debris in these non-Heinrich cold - phases than in warm phases, but is that an
ice - dynamical signal, a survival - of - icebergs signal, or something else?).
Read the studies by John Wettlaufer of Yale and others if you want to learn more
about the chaotic nature of
ice behavior on short time scales.
IPCC synthesis reports offer conservative projections of sea level increase based on assumptions
about future
behavior of
ice sheets and glaciers, leading to estimates of sea level roughly following a linear upward trend mimicking that of recent decades.
«There's been a lot of speculation
about the stability of marine
ice sheets, and many scientists suspected that this kind of
behavior is under way,» Ian Joughin, a glaciologist at the University of Washington in Seattle, said in a news release
about one of the studies published Monday.
