Ice Sheets Melt: Academics Waking Up; New York Times In Denial

There has never been a more important moral, philosophical, military, civilizational, psychological, sociological and economic issue than the concerted holocaust of the biosphere by Homo Sapiens, presently passing one tipping point after another. Thus I will not present excuses for keeping abreast of any advance in understanding in the field. Even if it is just to confirm what I have long said.

The first scientific paper including computerized models of ice sheets melt predicts the obvious: if we burn all PROVEN fossil fuels reserves, ice will completely melt, all over Earth. Yet, it is a big surprise to most scientists.

“This is humanity as a geologic force,” said Ken Caldeira, a researcher at the Carnegie Institution for Science in Stanford, California, an author of the paper. “We’re not a subtle influence on the climate system – we are really hitting it with a hammer.”

Nice to read. Nietzsche was doing philosophy with a hammer, we went further: we are doing climate with a hammer. Hopefully, it will crack soon: nothing like a great catastrophe to bring further fascism. Nihilism is bad thing, naivety, even worse. To please the powers that be, and thus to be taken seriously, serious climate scientists have made unwarranted, profoundly unscientific, over-optimistic declarations about the ice sheets. Now they time is up. In truth the GreenHouse emissions are completely out of control, and still increasing… At a geological scale, every year:

50 Gigatons Per Year: This GreenHouse Is Bigger Than CO2 Alone

“I didn’t expect it would go so fast,” Dr. Caldeira said. “To melt all of Antarctica, I thought it would take something like 10,000 years.” Didn’t they all. Why? Because only then would one be invited at the White House. Thinking correctly means, first, to think in a way that pleases those with power.

“Combustion of available fossil fuel resources sufficient to eliminate the Antarctic Ice Sheet” [Ricarda Winkelmann, Anders Levermann, Andy Ridgwell, Ken Caldeira]:

“The Antarctic Ice Sheet stores water equivalent to 58 meters in global sea-level rise. We show in simulations using the Parallel Ice Sheet Model that burning the currently attainable fossil fuel resources is sufficient to eliminate the ice sheet. With cumulative fossil fuel emissions of 10,000 gigatonnes of carbon (GtC), Antarctica is projected to become almost ice-free with an average contribution to sea-level rise exceeding 3 meters per century during the first millennium. Consistent with recent observations and simulations, the West Antarctic Ice Sheet becomes unstable with 600 to 800 GtC of additional carbon emissions. Beyond this additional carbon release, the destabilization of ice basins in both West and East Antarctica results in a threshold increase in global sea level. Unabated carbon emissions thus threaten the Antarctic Ice Sheet in its entirety with associated sea-level rise that far exceeds that of all other possible sources.”

The famous Doctor Hansen and his collaborators upset the establishment two months ago by predicting a rise of three meters within 85 years (they use the reasoning I have used before, namely that paleontological data show sea level rise of 5 to 9 meters, with a rise of just one degree Celsius; actually the reasoning was obvious since 2009, when I pointed out that “2C Is Too Much“). The new paper potentially confirms Hansen’s findings. As I said, the new paper tries to NOT upset the powers that be (differently from yours truly, who views most individuals and institutions in power more than suspiciously, and it shows).  Thus, one has to read between the lines to deduce that, from the paper itself, interpreting it optimistically is completely unwarranted.

The paper says: “Consistent with recent observations and simulations, the West Antarctic Ice Sheet becomes unstable with 600 to 800 GtC of additional carbon emissions.” Hmm… Let’s see, how long would that take, at the present increasing rate? Now emissions of CO2 itself are around 35 Gt, per year (35 billion tons of CO2, per year). That’s a number often brandished, but, left at that, it’s disinformation.  With other GreenHouse Gases, we are at 50 Gigatons of CO2 equivalent emission, per year. Sorry for taxing the mathematical capabilities of our great leaders:  12 x 50 = 600. This fits perfectly my “Ten Years To Catastrophe” essay. Thus, the West and EAST Antarctic Ice Sheet becomes unstable in TWELVE YEARS (according to this paper; I obtained the same rough estimate with a paleoclimatic approach).

The United Nations has said that the rise of the sea would not likely exceed three feet in this century. Some island nations will be wiped out (oops). Yet experts officially hope that major cities could be protected from it, in the richest countries that is (re-oops), though at a cost in the trillions of dollars (contemplate the enormous works to protect London or Venice).

The New York Times mentioned the paper above, which say the ice sheets will start melting irreversibly within a decade, to argue, in Politically Correct fashion, that ice sheets respond slowly enough to changes in the climate that it simply takes longer than a century for large-scale melting to begin. As if that notion was in the paper. It is not. Far from it. As I have argued before, that notion is ridiculous.

Indeed, warm water will rush below the ice sheets in West Antarctica, and East Antarctica’s immense Wilkes and Aurora subglacial basins.

Subglacial Basins Are The Achilles’ Heel Of The Biosphere

{WAIS = West Antarctica Ice Shelf; WB = Wilkes Basin; AB = Aurora Basin.]

Yet from that (tipping) point on, the paper found that thereafter, the sea would rise at the rate at a foot per decade, ten times faster than now, the New York Times admitted.

However the real text is much more alarming. Here is an extract:

“The Antarctic Ice Sheet is severely affected by high carbon emissions through both the marine ice-sheet instability and surface elevation feedbacks. On the time scale of millennia, large parts of the ice sheet melt or drain into the ocean, raising global sea level by several tens of meters. Most of the ice loss occurs within the first millennium, leading to high rates of sea-level rise during this period (Fig. 3; for more details, see also fig. S6). Our simulations show that cumulative emissions of 500 GtC commit us to long-term sea-level rise from Antarctica of 1.15 m within the next millenium, which is consistent with the sensitivity of 1.2 m/°C derived with a different ice-sheet model (33, 34). Paleo data suggest that similar rates of sea-level rise have occurred during past warm periods (35). If the 2°C target, corresponding to about 600 GtC of additional carbon release compared to year 2010, were attained, the millennial sea-level rise from Antarctica could likely be restricted to 2 m. In our simulations, this would keep the ice sheet below the threshold for the collapse of the Wilkes Basin. However, if that threshold is crossed, the Antarctic ice cover is significantly reduced in thickness and area (Fig. 4). If we were to release all currently attainable fossil fuel resources, Antarctica would become almost ice-free. It is unclear whether this dynamic discharge would be reversible and, if so, on which time scales.”

As I already said, since 2010, we have added another 230 Gigatons. So we are within eight year of the Wilkes ice sheet, the largest in the world, to become unstable. The paper admitted that about half the Antarctic ice sheet would melt or fall into the sea in the first thousand years.”

The New York Times’ interpretation  that it will take nearly a century for dramatic melting to start was obviously tainted. It is just driven by political Machiavellianism: let’s admit there is climate “change” just as there is sea level “change”, and misinform about the unfolding catastrophe (although Main Stream Media had to recently admit the snow pack in California last April was the lowest in at least 500 years). How do I know this? The scientific paper used computerized models of the huge ice sheets covering Antarctica and Greenland. It is the first paper to do so. Yet, according to the biased New York Times, it would have found exactly what the UN found, during this century… Although the UN did not incorporate the ice sheet melt models.

Once the ice sheet melting is incorporated, faster melting ought to have been predicted, for THIS century. However that grim prediction would have upset the powers that be. We don’t want that to happen. Now that they have the drone habit, killing throngs of people they know nothing about, who knows what’s coming next if one disparages them? Beheading and crucifixion at the most esteemed Saudi plutocracy?

For plutocrats, the Saudis are a model of Human Rights: thus they elected them to head the UN panel on Human Rights. And ice sheet melting is perfect: all great catastrophes call onto lining up fanatically behind whom Obama celebrates as our “leaders” (our masters). If a bit of engineered inflation could bring Hitler, imagine what an inflating ocean can bring! A great future for the few who rule us, tax-free.
