Every day I'll be posting
a different ice level, complete with screenshots and write - ups.

«One of the big questions is: Why was the climate and why were CO2
levels so
different during
ice ages than during warm times?
Each day, ENDURANCE (Environmentally Non-Disturbing Under -
ice Robotic Antarctic Explorer) was lowered through a hole in the
ice and used its sensors to take readings in
different parts of the lake — temperatures, light
levels, solar radiation and dissolved organic matter.
Today we are pushing the carbon dioxide
level to a height it last reached 24 million years ago, when there was a lot less
ice on Earth and the climate was very
different.
«This does not necessarily mean that a similar response would happen in the future with increasing CO2
levels, since the boundary conditions are
different from the
ice age,» added by Professor Gerrit Lohmann, leader of the Paleoclimate Dynamics group at the Alfred Wegener Institute.
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).
, 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.
While some earlier studies, 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.
GRACE - FO and ICESat - 2 will use radically
different techniques to observe how the massive
ice sheets of Greenland and Antarctica are changing over time and how much they are contributing to sea
level rise.
Numerical computer modelling of the glacier for these
different time periods will help us understand whether this part of the
ice sheet is susceptible to rising sea
level, warming oceans or increased atmospheric temperatures.
PvZ: Early in the progression, players will be unlocking all of their core abilities, but as they
level up further, players will earn weapon attachments and new outfits that allow them to augment their primary abilities with
different variations like
ice, fire, toxic, electric, dark energy and numerous other crazy powers.
Each
level in the game features
different background graphics that range from arctic
ice to forested mountains, but these are just window dressing.
One of the biggest challenges was to create a set of
levels that exploit the
different individual special abilities of each character: Anna's double jump, Elsa's
ice magic, Olaf's tumbling ability and Kristoff's
ice axe.
Ice Age Avalanche offers
level - based missions, each with a
different goal.
The regular
levels are well lit up and filled with green grass as they float in space for no reason, but there are also
levels covered in
ice and snow, and
levels that are in complete darkness that has
different enemies.
More ground turns from white reflective snow to black, heat absorbant dirt.The same effect occurs as sea
ice is lost.The corals blanch, and, as I stated last year on this site, the shutdown of the north Atlantic current will occur, since the salinity
level studies I spoke of last year, off Greenland, continue to show that the upwelling mechanisms driving the North Atlanic current are in severe jeapordy, because the change in salinity
levels effects the driver of the current, the upwelling and downwelling of
different salinity
levels off Greenland.
One more point: Isn't it possible that salinity
levels, in particular, are
different now in the ESAS than they were about 8000 years ago in the HCO, not long after most of the
ice age
ice sheet melted?
Given that some scientists were predicting an
ice free North pole in 2008, I think the thrust of the article correctly points out that maybe the global
ice level isn't all that
different than it was in 1979.
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.
So the
level of
ice albedo feedback was radically
different from the modern period during the MWP?
«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.
He found the pre-industrial
level little
different from the current
level, and the variability from year to year was much wider than the
ice core and Mauna Loa record showed.
The
level of saltiness changes the
ice's electrical properties, causing the
ice to
different levels of radio waves in the microwave band of the electromagnetic spectrum.
, 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).
A new report from the World Meteorological Organization warns that the current climate is bringing Earth into «truly uncharted territory,» highlighting the exceptionally low sea
ice and rises in ocean heat, global temperatures, and sea
levels experienced by
different parts of the world.
