Don't Believe In Abrupt Sea Level Change - Know About It - 3

Fig. 1 Blood of Oil-Qaeda, Worse than lava
Substantial discoveries in Antarctica which will impact the U.S. East Coast are currently becoming more of a part of reality.

As regular readers know, from time to time Dredd Blog has uncovered this under-the-cover ice sheet reality which, as usual, is a reality that is considered by the timid to be more like science fiction than the science fact that it really, really is:
"UCL Professor Duncan Wingham, who led the team, said: "Previously, it was thought water moves underneath the ice by very slow seepage. But this new data shows that, every so often, the lakes beneath the ice pop off like champagne corks, releasing floods that travel very long distances."
(Weekend Rebel Science Excursion - 45, emphasis added). As shown @ Fig. 1, this reality is coming home to roost:
"... the new picture—gradually revealed by space and airborne instruments, ground-based GPS and increasingly sophisticated computer models—is one of intricate and dynamic hydrology. Rapidly flowing subglacial streams channel water from one hidden lake to another, sudden drainage causes massive collapse, and the meltwater speeds the slide of mighty glaciers toward the sea.

The big picture was put together by a group of researchers specializing in oceans and ice and published in The Royal Society of London’s “Philosophical Transactions A” in August 2016. It shows significant progress in the understanding of Antarctica’s under-ice lake systems ... “Ten years ago, we didn’t realize subglacial lakes were so active,” said Helen Fricker of the Scripps Institution of Oceanography, a member of NASA’s Sea Level Change Team and lead author of the research group’s review article. “We didn’t realize water moves so quickly from one lake to another. We didn’t know it was a dynamic system, where water could transfer so quickly ... Previous studies using other techniques estimated the average melting rates at the bottom of Dotson and Crosson ice shelves to be about 40 feet per year (12 meters per year). Khazendar and his team, using their direct radar measurements, found stunning rates of ice loss from the glaciers' undersides on the ocean sides of their grounding lines. The fastest-melting glacier, Smith, lost between 984 and 1,607 feet (300 and 490 meters) in thickness from 2002 to 2009 near its grounding line, or up to 230 feet per year (70 meters per year) ... "If I had been using data from only one instrument, I wouldn't have believed what I was looking at, because the thinning was so large," Khazendar added. However, the two IceBridge instruments, which use different observational techniques, both measured the same rapid ice loss.
(Beneath Antarctic ice: lakes, floods and flowing water, 2016, emphasis added). Yes, startling surprises caused by these phenomena are characterized as "850 year events" when they finally reach "the homeland" these days:
Our analysis of multi-decadal tide gauge records along the North American east coast identified an extreme sea-level rise event during 2009–2010. Within this relatively brief two-year period, coastal sea level north of New York City jumped by up to 128 mm. This magnitude of inter-annual sea level rise is unprecedented in the tide gauge records, with statistical methods suggesting that it was a 1-in-850 year event.
(The Question Is: How Much Acceleration Is Involved In SLR? - 4). One reason for that is because establishment science is "conservative" to a dangerous fault.

For decades they have been thinking in terms of the "it will never melt because it is so stable" myth:
"I suspect the existence of what I call the `John Mercer effect'. Mercer (1978) suggested that global warming from burning of fossil fuels could lead to disastrous disintegration of the West Antarctic ice sheet, with a sea level rise of several meters worldwide. This was during the era when global warming was beginning to get attention from the United States Department of Energy and other science agencies. I noticed that scientists who disputed Mercer, suggesting that his paper was alarmist, were treated as being more authoritative.
I believe there is a pressure on scientists to be conservative. Papers are accepted for publication more readily if they do not push too far and are larded with caveats. Caveats are essential to science, being born in skepticism, which is essential to the process of investigation and verification. But there is a question of degree. A tendency for `gradualism' as new evidence comes to light may be ill-suited for communication, when an issue with a short time fuse is concerned."
(On Thermal Expansion & Thermal Contraction - 8, quoting Dr. Hansen). "Tell it like it is" tends to not be the way of scientists who are managed by Oil-Qaeda and its minions.

Stay awake more than ever now, even as the denial of reality increasingly blinds officialdom ("The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive") because of the surge of another unfortunate reality (Agnotology: The Surge, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17).

Think of the Agnotology generators as educational system neutralizers, invoked to cover the trail of murderous Oil-Qaeda (Humble Oil-Qaeda).

If the denier cabal, which is currently drooling over their newfound governmental powers, gets its way the science textbooks will become Voynich manuscripts (Ancient Ecocosmology?).
