In contrast, the much more expansive ice volume maxima (equivalently, sea level minima) during a glacial maximum is more defined.

Sea level dropped during the last glacial maximum, but there was no ice sheet in Siberia, so the surface was exposed to the really cold atmosphere, and the ground froze to a depth of ~ 1.5 km.

He makes the following statement, which is misleading if not outright wrong: Paleo records shows that both temperature and sea level have been mostly rising since last glacial maximum and more recently, since the so called little ice age.

(If all LL GHGs disappeared, global temperatures would plunge initially at 4 °C / year, thus dropping to maximum - ice - age levels in ~ 18 months.)

We've had both situations in the past — «Amsterdam» under ice about 20,000 years ago at the last glacial maximum, and «Amsterdam» under water in the Pliocene, 3 million years ago, when CO2 and sea level were higher than today.

It also reproduces the Eemian - last glacial transition where CO2 levels remained high, while temperatures were near minimum (and ice sheet formation was near maximum).

iheartheidicullen @ 162: Sorry if my tone was intemperate, but really the SH and NH sea ice trends have been analysed at length online by Tamino and others, over the last year or two, with the clear conclusion that the SH anomaly trend is small (the anomaly at the maximum last year was about 1.5 % of the mean annual maximum, if I remember correctly) and not statistically significant (at the 95 % level, I think), whereas the NH trend is large (tens of percent), long - lived, and statistically very significant indeed.

But once the ongoing effect of warming shocks to the glacier front were modeled for the next 90 years, a maximum realistic sea - level rise from Greenland's ice - loss was 2 inches.

The maximum CO2 concentration levels from any ice core record is 298.7 ppm.

Second, he demonstrated that prevailing estimates of the 20th century GMSL rise (~ 1.5 to 2.0 mm / year), after correction for the maximum signal from ocean thermal expansion, implied mass flux from ice sheets and glaciers at a level that would grossly misfit the residual GIA - corrected observations of Earth's rotation.

There is very high confidence that maximum global mean sea level during the last interglacial period (~ 129 to 116 ka) was, for several thousand years, at least 5 m higher than present and high confidence that it did not exceed 10 m above present, implying substantial contributions from the Greenland and Antarctic ice sheets.

The iceberg delivery of sediment containing nanoparticulate Fe during the Last Glacial Maximum (18000 — 21000 years ago) may have been sufficient to fertilize the increase in productivity required to drawdown CO2 to the levels observed in ice cores [9].

The truth is that in the arctic we're seeing record low levels of sea ice year after year, including just this year, when in March the North Pole saw the lowest maximum ice extent on record.

23 March 2018... KTUU Anchorage, Alaska (Quoted): Arctic sea ice hits annual maximum at near record low levels

Global sea levels have been rising since the glacial maximum of the last ice age some 18,000 years ago, but observations indicate that the rate of sea level rise is not accelerating and may even be decelerating.

As Arctic sea ice approaches its annual maximum level for the year, now is a good time to look at how it stands — especially in what some are claiming to be the hottest year on record.

At the other side, the end of the Eemian is interesting that it shows a cooling to a new minimum (and ice sheets to a new maximum — both at about 75 % of the previous opposite directions) while CO2 levels remained high.

Ice levels since that time have shown a decrease in maximums of around 2.6 percent per decade.

Arctic sea ice reached its maximum annual extent on March 21, and the amount measured was the fifth - lowest level ever recorded.

Our estimated sea levels have reached +5 to 10 m above the present sea level during recent interglacial periods that were barely warmer than the Holocene, whereas the ice sheet model yields maxima at most approximately 1 m above the current sea level.

Lambeck, K., Rouby, H., Purcell, A., Sun, Y. & Sambridge, M. Sea level and global ice volumes from the Last Glacial Maximum to the Holocene.

Independent analyses designed to separate ice volume and temperature change, such as Dwyer & Chandler [64], find sea - level maxima and variability comparable to our estimates.

Dwyer & Chandler [64] separate Pliocene ice volume and temperature in deep ocean δ18O via ostracode Mg / Ca temperatures, finding sea - level maxima and oscillations comparable to our results.

CO2 minima were reached approximately when the sea level was at a minimum, hence, the extent of the continental ice sheets were at a maximum, and the highest CO2 levels were found during interglacials during the high stands of the sea level.

This is likely due to the maximum orbitally forced summer insolation, enhancing the melting of ice sheets and thus a sea - level rise.

Temperature and CH4 levels were already at a minimum and ice sheet building already at a new maximum before CO2 levels started to drop.

The past six years have produced the six lowest maximums in that record, and the new data show that the percentage of older, thicker and more persistent ice shrank to its lowest level ever, at just 9.8 percent of the winter ice cover.

Fleming, K. & Lambeck, K. Constraints on the Greenland Ice Sheet since the Last Glacial Maximum from sea - level observations and glacial - rebound models.

While the IPCC projected a maximum 23 - inch sea - level rise before 2100 as a result of rising temperatures, Gore's statement predicted a 20 - foot rise in sea levels if the Greenland or West Antarctic ice sheets were to melt or collapse at an indefinite point in the future.

This could explain why this year the growth of the Antarctic sea ice cover, which currently is headed toward its yearly maximum extent and was at much higher than normal levels throughout much of the first half of 2015, dipped below normal levels in mid-August.

But thanks to human - caused global warming, that maximum seasonal spread of the ice has been shrinking over the years — and this past March it reached the lowest level ever observed for the month.
