[48] The Cryosphere Today, «Global Sea - Ice Area, 1979 - Present,» University of Illinois Urbana — Champaign, http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg (accessed February 3, 2016).

For example, the dramatic decline of summer sea ice in the Arctic — a loss of ice cover roughly equal to half the area of the continental United States — exacerbates global warming by reducing the reflectivity of Earth's surface and increasing the amount of heat absorbed.

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).

The small global mean change, however, is expected to create large problems in sensitive areas of the Earth system — rising sea level leading to increased coastal flooding, more heat waves and drought, and the disappearance of summer Arctic sea ice, to name a few.

Then, in the beginning days of February, the Arctic sea ice extent and area both broke records again, as the entire global sea ice area entered the second - lowest range ever to have been recorded.

Mean sea level (MSL) evolution has a direct impact on coastal areas and is a crucial index of climate change since it reflects both the amount of heat added in the ocean and the mass loss due to land ice melt (e.g. IPCC, 2013; Dieng et al., 2017) Long - term and inter-annual variations of the sea level are observed at global and regional scales.

My own view is that the initiating mechanism is not small shifts in insolation hitting some kind of trigger related to snow albedo (the land - sea snow - ice area is relatively small compared to potential shifts in cloud amount and spatial distribution)-- rather it is shifts in global winds which likely relate to shifts in the jetstream (linked to...?

Unless global temperatures are stabilized, higher seas from melting ice sheets and mountain glaciers, combined with the heat - driven expansion of ocean water itself, will eventually lead to the displacement of millions of people as low - lying coastal areas and island nations are inundated.

The acceleration of ice loss in both Greenland and Antarctica has caused another upward revision of global sea - level rise and the numbers of refugees expected from low - lying coastal areas.

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.

Global mass balance data are transformed to sea - level equivalent by first multiplying the ice thickness (meters) lost to melting by the density of ice (about 900 kilograms per cubic meter), to obtain a water equivalent thickness, and then multiplying by the surface area of these «small» glaciers (about 760,000 square kilometers).

«It is unlikely that coastal cities or low - lying areas such as Bangladesh, European lowlands, and large portions of the United States eastern coast and northeast China plains could be protected against such large sea level rise,» states a report co-authored by Hansen, titled «Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2 °C Global Warming is Highly Dangerous&raqusea level rise,» states a report co-authored by Hansen, titled «Ice Melt, Sea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2 °C Global Warming is Highly Dangerous&raquSea Level Rise and Superstorms: Evidence from Paleoclimate Data, Climate Modeling, and Modern Observations that 2 °C Global Warming is Highly Dangerous».

The report singles out coastal areas, including low - lying island nations, as hot spots of elevated risk that may not be completely manageable due to the steady climb in global sea levels projected to take place during the rest of this century, as the planet warms and land - based ice sheets melt.

For an annual - and area - average warming exceeding Embedded Image in Greenland and Embedded Image in the global average, the net surface mass balance of the Greenland ice sheet becomes negative, in which case it is likely that the ice sheet would eventually be eliminated, raising global - average sea level by 7 m.
