Fig. 1 Ice Streams of Greenland |
I. Introduction
The Northeast Greenland Ice Stream (NEGIS) drains about 16% of all the Greenland Ice Sheet (GIS) as depicted at Fig. 1.
The Jakobshavn Ice Stream (JI) drains about half of the NEGIS quantity (Northeast Greenland Ice Loss Accelerating).
Regular readers will note that Dredd Blog System has recently posted several pieces concerning the impact of Greenland on the Northeast U.S. from Cape Cod, MA south to Cape Hatteras, NC (e.g.The Question Is: How Much Acceleration Is Involved In SLR - 5?).
The gist of the subject matter is that catastrophic sea level rise (SLR) is much, much closer, in time and in geography, than is being reported in U.S. mainstream media.
II. The Invasion Forces
A. The Global Axis of Ice

2:43 - "One meter [of SLR] would be a global catastrophic event, 3 meters would remap the world as we know it?"(emphasis added). This allows us to focus our attention on 1m / 3ft. of SLR, because it would be "a global catastrophic event."
2:50 - "Yes, absolutely."
The delicacy of the issue can be seen (Fig. 2) by realizing that only 1.14% of the global ice volume needs to melt to get us there (3 ft ÷ 263.5 ft. = 0.011385 = 1.14%).
The overall invader needs to use only 1.14% of its forces to accomplish the invasion.
B. Invasion Forces from Antarctica
If a small portion of one glacier (the Totten Glacier) in East Antarctica melts, or otherwise slides into the sea, the same will happen:
(Why Sea Level Rise May Be The Greatest Threat To Civilization). That is a slim margin, because the Totten Glacier is showing signs of decomposition (Nature)."How little it will take can also easily be seen by a statement from a scientist who is studying those locations closely and regularly:
Fig. 3 Totten Glacier, Antarctica
'One of them, Totten glacier, holds the equivalent of seven metres of global sea level.'(Dr. Rignot East Antarctica glaciers, cf. Totten Glacier Melting). The percentage of that one glacier which needs to melt to cause 3 ft. / 1 m. of SLR is: 1÷7 = 0.142857143 = 14.3%."
C. Invasion Forces from Greenland
In Section I, above, several ice streams and/or glaciers are discussed and shown, along with the path they are taking to the sea (Fig. 1).
The NEGIS is 16% of the entire GIS, JI is 8%, while KG & HG are at ~2% each.
These four entities make up 28% of the total ice in the GIS.
The entire GIS represents 21.49 ft. of SLR (Fig. 2), so 28% of that is (21.49 × .28) 6.02 feet.
Which means that only half of that amount (14%) is needed to reach "3 ft. / 1 m. of SLR."
III. The Odds of "Victory"
A. Considering All of the Invasion Forces
Some East Coast areas of the U.S. are half way to "3 ft. / 1 m. of SLR" already
(Will This Float Your Boat - 10, Why Sea Level Rise May Be The Greatest Threat To Civilization - 2).
Thus, the percentage of global ice that has to melt to get us to "a global catastrophic event" in that area is now one half of what it was.
In Section II.A above, that global percentage is expressed as 1.14%, so (1.14% ÷ 2) = 0.57% (less than 1% until
That is to say, when 0.57% more of global ice melts and its ice or water reaches the sea, the invasion of the U.S. East Coast will be accomplished.
B. Considering Only the Totten Glacier Invasion Force
In Section II.B above, it was pointed out that "3 ft. / 1 m. of SLR" would be attained if only 14.3% of one glacier in Antarctica reaches the sea.
Since we are already half-way there, the remaining percentage is (14.3% ÷ 2 ) 7.15%.
C. Considering Only the Ice Streams of Greenland
In Section II.C above, it was pointed out that "3 ft. / 1 m. of SLR" would be attained on the East Coast of the U.S. if only 14% of Greenland ice streams reach the sea.
D. Considering The Combined Invasion Forces
Since we were looking at those ice melt events individually, as separate, singular occurrences, consider the reality that all of these SLR causing ice melt events are happening at the same time.
Now!
That is, all the mentioned ice streams in Greenland, as well as the Totten Glacier in Antarctica, are already melting at the same time.
Add to that, the fact that many, many other glaciers in both Greenland and Antarctica, that were not mentioned, are also part of the invasion forces of melting ice induced SLR.
IV. Why?
The reason this is happening is because current civilization is not complying with the Tenets of Ecocosmology.
Therefore current civilization is failing The Test (ibid).
Our civilization is lost in space, living on a planet that is not understood sufficiently (You Are Here).
V. Conclusion
Since the U.S. is relentlessly invading the Arctic as well as beginning offshore Atlantic Ocean drilling (Oil-Qaeda & MOMCOM Conspire To Commit Depraved-Heart Murder), thereby perpetuating the criminal epoch (The Criminally Insane Epoch Arises), the response of Mother Nature is to continue her invasion (Arctic Sea Ice in Uncharted Territory, Sleeping Giant in the Arctic).
Don't die for it |
The SLR victory over the U.S. will not be pretty (Will This Float Your Boat - 10, 9, Why Sea Level Rise May Be The Greatest Threat To Civilization, 2).
Urge your congressional representatives and the president to surrender now.
Leave it in the ground (LINGO).
Turn around, don't drown (TADD).

War destroys vast swaths of nations.
ReplyDeleteCities are ruined, people must migrate, martial law engulfs government thinking and doing.
Hunger, disease, and despair spread.
Sea lever rise will do that.
The difference between sea level rise and war is that the seal level rise does not have a Marshall Plan, or a notion that "the war is over.".
It just keeps on keeping on.
"sea level rise"
DeleteOne scientist opines that the NEGIS has basal melt attributable to sub-glacial volcanoes (High Geothermal Heat Flow, Basal Melt, and the Origin of Rapid Ice Flow in Central Greenland).
ReplyDeleteSo, there is summer basal melt induced acceleration caused by surface melt water flowing into crevasses, but there is winter basal melt acceleration too, caused by other dynamics (see e.g. Winter speed-up of quiescent surge-type glaciers in Yukon, Canada).
I should add that compressed ice melts at a lower temperature than non-compressed ice (i.e. it melts below 32 deg. F / 0 deg. C) and is most compressed at the base of the glacier where it meets bedrock.
DeleteThus, friction and geothermal sources can induce melting, which adds lubricating melt water, which in turn allows acceleration.
Even in winter.
