One is changed environmental conditions
for a discrete subpopulation of the original population, such as when
ice ages cause dramatic changes in
sea levels, cutting species into subgroups.
Scientists from Rice University and Texas A&M University - Corpus Christi's Harte Research Institute
for Gulf of Mexico Studies have discovered that Earth's
sea level did not rise steadily but rather in sharp, punctuated bursts when the planet's glaciers melted during the period of global warming at the close of the last
ice age.
Whereas most studies look to the last 150 years of instrumental data and compare it to projections
for the next few centuries, we looked back 20,000 years using recently collected carbon dioxide, global temperature and
sea level data spanning the last
ice age.
You know, a new ocean is being created

Evidence
for the maximum lowering of
sea level during successive
ice ages over the past several millions of years is sparse.
As
sea levels rose during the last
Ice Age, the cave flooded and its roof collapsed into this sinkhole resulting in a marine wonder known
for its sparkling blue waters, wealth of coral formations, sharks and fish, and deep caves filled with stalactites.
Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods
for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data
for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little
Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global
sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).
I can't wait
for the explanations when that happens — as in that movie «The Day After,» in which it is revealed that global warming actually leads to an
ice age because the Gulf Stream gets re-routed and no longer warms the North
Sea.
Below you'll hear from scientists with significant concerns about keystone sections of the paper — on the evidence
for «superstorms» in the last warm interval between
ice ages, the Eemian, and on the pace at which
seas could rise and the imminence of any substantial uptick in the rate of coastal inundation.
(The recent work of Huybers and Langmuir suggests that on
ice -
age time scales, the loading and unloading of the planet by
ice growth / shrinkage and
sea - level fall / rise may weakly organize the volcanoes, but not a lot, and with nothing interesting
for our time.)
o 8000 of the 10000 years since the last
ice age were warmer than now and generally had less CO2 and lower
sea levels o
For 3000 years (from 5000 BP to 2000 BP) world temperatures were falling whilst CO2 levels were rising o Manâ??
Remember
for a long time «pingos» were surface land features — odd hills on the flat tundra, in areas that that had been under the
ice age ice, then had been underwater as that
ice melted and
sea level rose, then exposed again during the next
ice age.
It is also possible
for cold climates to increase chemical weathering in some ways, by lowering
sea level to expose more land to erosion (though I'd guess this can also increase oxydation of C in sediments) and by supplying more sediments via glacial erosion
for chemical weathering (of course, those sediments must make it to warmer conditions to make the process effective — downhill and downstream, or perhaps via pulsed
ice ages -LRB-?)-RRB-.
eg 6 Conclusions We have developed a new algorithm
for estimating
sea ice age distribution using
sea ice drift and concentration products.
--
Sea level has been rising at 1 mm to 3 mm every since the large continental glaciers melted after the last
ice age — ie
for the last 9,000 years.
Regarding conditions
for spring 2012, Figure 4 shows maps of
ice categories derived from
sea -
ice age for the beginning of May 2012, with maps
for early May and mid-September 2011 included
for comparison.
Since the end of the last
ice age, The Marshall Islands have survived 130 metres of
sea - level rise, but the last 1.43 mm / year since 1950 is going to sink them, therefore compensation must be paid
for by Western nations!
Since the end of the last
ice age, Pacific Island atolls have survived 130 metres of
sea - level rise, but global warming alarmists like Mark Kenny think that the last 1.43 mm / year since 1950 is going to sink them, therefore, compensation must be paid
for by Western nations.
The
ice age product is based on a 15 %
sea ice concentration threshold to be consistent with the threshold used
for mapping overall
sea ice extent.
Because hurricane caused flooding was more prevalent during the Little
Ice Age when Atlantic temperatures averaged 1 to 2 degrees F colder than today researchers concluded, «The frequent occurrence of major hurricanes in the western Long Island record suggests that other climate phenomena, such as atmospheric circulation, may have been favorable
for intense hurricane development despite lower
sea surface temperatures.»
«Our investigations show that uplift of the
sea floor in this region, caused by the melting of the
ice masses since the end of the last
ice age, is probably the reason
for the dissolution of methane hydrate.»
As
for an
ice age at the 65million year extinction, don't forget that at that time there was no
ice anywhere on the planet, no greenland
ice sheet, no antarctic
ice sheet, no arctic
sea ice.
Conversely, during low solar activity during the Little
Ice Age, transport of warm water was reduced by 10 % and Arctic sea ice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibili

Satellite - derived estimates of
sea -
ice age and thickness are combined to produce a proxy
ice thickness record
for 1982 to the present.
Estimated
ice age for June 21, 2010 from the University of Colorado satellite - derived (Lagrangian drift)
sea ice age (in years).
The latest
ice age product (Figure 1), provided by Maslanik
for June 21, 2010, shows the same lobe of old
ice extending through the Beaufort
Sea and into the Chuckhi
Sea that was seen in the end of April product (see June report).
Comparing the latest
ice age data from Maslanik and Fowler (see Maslanik contribution)
for 21 June 2010 (Figure 6) to current (20 July)
ice extent data shows that the
ice edge has retreated back to the boundary between first - year and multi-year
ice pack in the eastern Arctic and in the Beaufort and Chukchi
seas.
It is unfortunate that maps of multi-year
sea ice distribution
for 2010 derived from QuikSCAT (provided by Nghiem) are no longer available to compare with
sea ice age calculations, as in previous years.
While the winter / spring 2008
sea -
ice extent has rebounded from the 2007 negative mega-anomaly, the
age - class distribution at present is negatively skewed compared to satellite climatology and even the values
for 2007, as is
ice concentration within the
ice - ocean margin that defines extent.
As noted last month, this range depends in part on the relative weight that the respondents give to «initial conditions,» e.g.,
age and thickness of
sea ice at the end of spring, versus whether summer winds in 2008 will be as supportive
for ice loss as the favorable winds were in 2007.
A challenge
for climate sleuths has been to find a place holding a series of corals dating back into and beyond the last
ice age, when
sea levels were more than 300 feet lower than they are now because so much water was locked up in glacial
ice.
Regardless, even the IPCC concedes that there was no significant anthropogenic influence on climate prior to 1950, thus man is not be responsible
for sea level rise beginning 150 - 200 years ago, at the end of the Little
Ice Age.

Obviously, no one disputes that
Sea Level has been rising since the last
Ice Age - very slowly; and certainly, if
Sea Level Rise (SLR) is or will accelerate rapidly, we need to know about it, and plan
for it; but, in short, it seems that the General Assembly want's actual proof, instead of using an Ouija Board to predict acceleration of
Sea Level Rise.
In response to your question I would refer you to my comment above Dave Wendt (14:39:39): where I discuss the Rigor and Wallace paper of 2004 which demonstrated that the decline in
sea ice age and thickness began with a shift in state in Beaufort Gyre and the TransPolar Drift in 1989 which resulted in multiyear
ice declining from over 80 % of the Arctic to 30 % in about one year and that the persistence of that pattern has been responsible
for the continuing decline.
I forgot to include the link
for the
sea ice age and buoy drift animation I referred to above.
Rigor et al.; 4.2 million square kilometers; Statistical —
age estimates In comparison to 2007 and 2008, there is much more first year (FY)
ice in the Beaufort and Chukchi
Seas in 2009, which we expect to precondition this area
for a more extensive retreat than in 2007 and 2008.
The
ice age lasted centuries because the eruptions probably triggered a lasting chain reaction in the ocean currents, «affecting
sea ice and ocean currents in a way that lowered temperatures
for centuries,» says the study's co-author.
For instance, the present Arctic with its wastes of tundra, glacier, and
sea ice is a legacy of the geological accident of the Ice A
ice is a legacy of the geological accident of the
Ice A
Ice Age.
Sea levels,
for example, have been increasing since the end of the last
ice age.
Radiative physics says doubling CO2 adds a lot more forcing to polar latitudes than the Milankovitch effect, but you demur on accepting that it is also important
for the
sea -
ice and glacier balance and possibly that higher CO2 levels near 500 ppm could prevent the next Ice A
ice and glacier balance and possibly that higher CO2 levels near 500 ppm could prevent the next
Ice A
Ice Age.
After ocean depths had cooled
for another 30 million years, Arctic
ice caps began to form and the earth entered an
age with multiple episodes of glacier advances and retreats causing
sea levels to rise and fall.
When the last
ice age ended, the oceans were very close to 120 m (nearly 400 feet) LOWER than today (NASA's own website) As
for runaway GHG induced heat, at the hight of our present right now,
sea levels are STILL 4 - 6 meters LOWER than they wrre during the previous interglacial.
• Rising
sea level will inundate shorelines (Al Gore)-- unless the Antarctic
ice shelf decides to fall into the Ocean all at once, it will take about 300,000 years
for this to occur at present melt rates and we'll be in an
ice age before it happens.
Several of these
sea - level accelerations occurred during the
Ice Age recovery and had
sea - level rises of 4 m per century (40 mm / yr) sustained
for several centuries during them.
What's the rough breakdown of
sea level rise attribution
for human GHG emissions and emergence from the little
ice age?
