When the top of the periscope came within sixty feet of the surface, he spotted heavy ice to the side.
You can make them go down just as easily by increasing that aerosol forcing within it's uncertainty bounds and the earlier «ice - age» model projections did exactly that — using surface temperature as a target.
We quantify sea - level commitment in the baseline case by building on Levermann et al. (10), who used physical simulations to model the SLR within a 2,000 - y envelope as the sum of the contributions of (i) ocean thermal expansion, based on six coupled climate models; (ii) mountain glacier and ice cap melting, based on surface mass balance and simplified ice dynamic models; (iii) Greenland ice sheet decay, based on a coupled regional climate model and ice sheet dynamic model; and (iv) Antarctic ice sheet decay, based on a continental - scale model parameterizing grounding line ice flux in relation to temperature.
This estimate was refined by Hansen and Nazarenko (2004), who used measured BC concentrations within snow and ice at a wide range of geographic locations to deduce the perturbation to the surface and planetary albedo, deriving an RF of +0.15 W mâ $ «2.

Researchers have repeatedly found evidence of an acceleration of melting, in some cases by looking at what is happening within the ice or on the surface, or by taking a new look at satellite data.
''... worked with two sediment cores they extracted from the seabed of the eastern Norwegian Sea, developing a 1000 - year proxy temperature record «based on measurements of δ18O in Neogloboquadrina pachyderma, a planktonic foraminifer that calcifies at relatively shallow depths within the Atlantic waters of the eastern Norwegian Sea during late summer,» which they compared with the temporal histories of various proxies of concomitant solar activity... This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate Anomaly, and again after ~ 1950 A.D.» In between these two warm intervals, of course, were the colder temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near - surface water temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale temperature variability of 1 to 2 °C magnitude.»
Sea surface temperatures were warm in coast areas, but near - freezing in the open water areas within the ice pack, which is expected given the recent ice melt in that region (Figure 7).
Anomalous cyclonic atmospheric circulation throughout the Arctic Basin during June has continued to precondition sea ice, making the ice cover vulnerable to a precipitous drop in sea ice extent; however the persistence of the June cyclonic circulation (and cloudiness associated with the surface lows) has induced divergence within the sea ice cover, and has delayed the onset of the rapid sea ice extent decline typically observed in June.
The area around the North Pole is ice - covered — an assumption confirmed by many airborne and ice - surface expeditions — but researchers use an average of the concentration just outside the gap to estimate the extent within.

Where meltwater forms on the ice - shelf surface, it can wedge open crevasses and cause ice - shelf disintegration, much like a line of balanced dominoes falling over, which has been observed to occur within weeks in the rapidly warming Antarctic Peninsula region (e.g., MacAyeal et al., 2003).
As you'll be well aware, surface air temperatures can easily change by 10 C within a day, for large bodies of ice to melt, or sea water to warm would take centuries.
