Robert Bindschadler of NASA and Tad Pfeffer at the University of Colorado, both glacier specialists, told me that they saw scant evidence that a yards - per - century rise in seas could be produced from the ice sheets that currently cloak Greenland and West Antarctica, which are very different than what existed in past periods of fast sea - level changes.
Polar amplication is of global concern due to the potential effects of future warming on ice sheet stability and, therefore, global sea level (see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different climate feedbacks, which determine the transient and equilibrium response to external forcings.
[Aug. 9, 8:04 p.m. Updated Joe Romm has predictably assailed my view of Arctic sea ice trends and their implications, straying into discussions of melting permafrost (which is an entirely different issue laden with its own questions — one being why the last big retreat of permafrost, in the Holocene's warmest stretch, didn't have a greenhouse - gas impact) and my refusal to proclaim a magically safe level of carbon dioxide (which I discuss here).
The CO2 level comes from half a dozen different ice core analyses, while the temperature data come from marine sediments, pollen analyses, isotopes, corals etc..
In some cases, these were due to a different orbital configuration, or different levels of greenhouse gases, or even different world geography (lower mountain ranges, ocean seaways altered, no polar ice sheets etc).
Does it give us a good indication of where levels will stabilize as different ice sheet melt.
Joe Romm has predictably assailed my rejection of his «death spiral» depiction of Arctic sea ice trends, straying into discussions of melting permafrost (which is an entirely different issue laden with its own questions — one being why the last big retreat of permafrost, in the Holocene's warmest stretch, didn't have a greenhouse - gas impact) and my refusal to proclaim a magically safe level of carbon dioxide (which I discuss here).
The numbers would have become slightly lower, but this approach would not have mixed up very different levels of uncertainty, and it would have been clear what is included in the table and what is not (namely ice flow changes), rather than attempting to partially include ice flow changes.
We interpret the split of 2013 Outlooks above and below the 4.1 level to different interpretations of the guiding physics: those who considered that observed sea ice extent in 2012 being well below the 4.1 level indicates a shift in arctic conditions, especially with regard to reduced sea ice thickness and increased sea ice mobility; and those who have estimates above 4.1 who support a return to the longer - term downward trend line (1979 - 2007).
Thus if one plots all the minima of the different historical measurements, that gives a better impression of the real «background» CO2 level than the averages: see The same for ocean data and coastal data: all are around the ice core level.
We interpret the split of 2013 Outlooks above and below the 4.1 median to different interpretations of the guiding physics: those who considered that observed sea ice extent in 2012 being well below the 4.1 level indicates a shift in arctic conditions, especially with regard to reduced sea ice thickness and increased sea ice mobility; and those with estimates above 4.1 who support a return to the longer - term downward trend line (1979 - 2007).
If you're talking about acceleration to extraordinary multi-metre sea level rises, that's a different topic and we'd probably have to discuss ice sheet dynamics.
That the ice core CO2 levels are reasonable for CO2 measurements can be seen as different ice cores at very different snow / ice temperatures, inclusions (coastal salts vs. inland salts content), accumulation rates, ice age — gas age differences,... show the same CO2 levels (within 5 ppmv) for overlapping periods of gas age.
All different observations of past CO2 levels have their own problems, be it chemical measurements, ice cores, stomata data or coralline sponges.
In contrast, the actual science shows something quite different: though summer sea ice since 2007 has declined to levels not predicted until 2040 - 2070, there has been virtually no negative impact on polar bear health or survival, a result no one predicted back in 2005.
Ongoing sea level rise due to the loss of ice mass into the sea is and will impact coastlines profoundly but to different degrees — i.e., the oceans are not a simple bathtub subject to uniform sea level rise.
There are other mechanisms acting on sea level changes that are different from esteric changes and ice melting.
This is different from the melting of Arctic sea ice, which dropped to its second - lowest level ever this year.

«IceBridge has collected so much data on elevation and thickness that we can now do analysis down to the individual glacier level and do it for the entire ice sheet,» said Michael Studinger, IceBridge project scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. «We can now quantify contributions from the different processes that contribute to ice loss.»
A different approach (Mitrovica et al, Nature 409:1026, (2001)-RRB- suggests melting of the Greenland ice complex over the last century has already contributed the equivalent of 0.6 mm per year of sea - level rise.

, using different approaches, have posited that Antarctic ice sheets could add as much as a metre to sea levels by 2100, this new evidence suggests ice loss on this scale is «implausible», the paper says.
For SON, similar regression patterns are obtained if different atmospheric levels (e.g. Z1000, Z500) are used instead of Z850, but Z850 was found to have the greatest correspondence with ABS sea ice anomalies (not shown).
If you can do so without being driven by desire simply to mock viewpoints different from yours, look at the ultra-slow effect of the thermohaline current, in addition to questionable ice - core CO2 measurements; the evidence is in different sensitive comparisons of delta CO2 levels with delta emissions levels, as well as isotope studies; nothing watertight proven but a lot of highly suggestive coherent evidence that it's bad science to neglect.
Most climatologists believe that if temperatures rise more than another 1 degree C by 2100, conditions on the planet could become radically different and disruptive, including sharp shifts in precipitation patterns, more severe storms and droughts, the disappearance of the Arctic ice cap in summer, Greenland ice sheet instability, and much higher sea levels.
Consequently, ice sheet contribution to sea level rise — even if it were the same amount — would have different impacts, depending on whether the contribution came from Greenland or Antarctica (Bamber and Riva 2010).
