In Search Of Ocean Heat - 12

Fig. 1 Amundsen Sea Sector
I. Background

In the previous post in this series I pointed out two papers that are falsifiable, (papers must be falsifiable to be properly composed), but these two are now falsified.

That is obviously not what the authors would have wanted, but we all make mistakes as we generate hypotheses as an attempt to discern natural events.

Anyway, in that post I did point out that, for one thing, they did not use TEOS-10 which is the international standard for seawater/oceanography research (TEOS-10 Software: Use It Or Lose It).

A. Paper One

The first paper that I criticized alleged that the ocean was at its "hottest in the historical record" (in terms of global warming impact) in 2022.

That can't happen unless the atmospheric global warming in 2022 was the "hottest in the historical record" (which as I pointed out, it wasn't).

2022 was the 5th warmest year on record.

So, the ocean received only the 5th warmest annual amount of warming.

B. Paper Two

The second paper I criticized alleged that the west wind did such a number on the Amundsen Sea area of Antarctica that we don't have to worry about a "runaway" ice sheet melt event there.

Nay, not so.

II. My Criticism Continues

I did some graphs with updated WOD, SOCCOM, Woods Hole, and OMG data composed of in situ measurements.

I processed, with TEOS-10 software, that in situ data from those sources related to all the "sectors" along the coast of Antarctica, including the Amundsen Sea area.

I then generated the graphs in Fig. 1 through Fig. 6 which show that the Conservative Temperature (CT) and the ice-melt-temperature of the tidewater glacier ice, together indicate that the grounding line area of those glaciers is constantly exposed to melt conditions no matter which way the wind blows.

A previous post's appendix reveals further information about this type of graph (Appendix D). 

The "sector" of each graph equates to the geographical "area" shown on Fig. 7 as follows: Area A [West Indian Sector], Area B [East Indian Sector], Area C [Ross Sea Sector], Area D [Amundsen Sea Sector], Area E [Bellingshausen Sea Sector], and Area F [Weddell Sea Sector] (see link at Fig. 7).

III. Scientists Who Inspired My Criticism

My criticism is in accord with statements by Dr. Rignot in a "talk" he gave following his being voted into the National Academy of Sciences:

Fig. 4 Ross Sea Sector
"So let me explain to you how this works. This is the Antarctic and [the] water column in the polar ocean is organized very differently from the tropics. You don't have warm water at the top and cold water at the bottom ... it's the opposite of cold water at the top and the warm water ... is at the bottom ... you have to lower instruments very deep down close to the glaciers ... that mixture of ice and sea water [h]as a melting point of minus 2 degrees at the surface and when the water is at two kilometres [(2000 meters)] [depth] becomes minus 3.5 so THERE'S PLENTY OF  HEAT AVAILABLE TO MELT THE ICE from beneath and ESPECIALLY IN THE DEEPER PART OF THE ICE THE GROUNDING LINE where we have RATES in Antarctic APPROACHING ... 100 METER PER YEAR whereas AT THE SURFACE THE RATE OF TURNOVER IS more like A METER PER YEAR. So it's 2 ORDERS OF MAGNITUDE DIFFERENCE FROM THE TOP AND BOTTOM and by melting the ice below from below you remove a lot of basal friction in front of the grade you lose you remove a lot of basal resistance to the flow and THE GLACIERS FEEL THAT  TREMENDOUSLY MUCH MORE THAN THE FEELING OF THE SURFACE. so the heat for the Antarctic comes from the Antarctic circumpolar current which circulates clockwise and is pushed by the westerly winds and you might ask how is changing to with climate warming and is related to climate warming so what's up insignia Antarctic is that we don't have a strong snoring video feedback it's too cold to melt the snow it's not nothing very much in fact ... the

models don't capture the change in wind in Southern Ocean they don't capture the way that warm water is carried onto the continental shelf and wishes the glaciers if you want a model to do that you cannot run it at a hundred kilometer resolution you have to run it at a kilometer resolution and we cannot do that with global models right now ... it started doing its thing in Antarctica all the red spots here are areas of rapid change and we saw ice shafts collapse in the 1990s and 2000 in the peninsula and witness that some of the glaciers not only felt the effect of less flow resistance in front of them they sped up by a factor three to eight in response to that now if you do a fall experiment and do this all around the Antarctic and collapse all these are shafts and say for that you speed up the gracious by a factor six point five you raise sea level by four meters per century and four meters per century it was exactly the rate that was observed for several century during meltwater pass one day fourteen thousand years ago when a lot of the ice sheets in the northern a sphere fell apart in some parts of Antarctica as well so it's not completely realistic to see that because it's happening in the Antarctic Peninsula we paid a lot of attention also in the
Fig. 6 W. Pacific Sector

Western Antarctic Ice Sheet sector in the Pine Island and Thwaites glacier this glacier is a hundred and twenty kilometers wide all of these glaciers feel the effect of more warm water they are spinning up by 75% they are retreating at one to two kilometers per year there's not a single glacier on the face of the earth in Alaska alpine landscape or Himalaya battery trees that bizrate these are the fastest retreating glaciers on the face of the earth but you wouldn't see it with a naked eye because it's happening a kilometer below the surface you can see it with satellite techniques another glacier that I got attention is Totten glacier this is a single glacier in East Antarctica which holds 3.5 meter sea level rise you don't want to teach that one but it's already showing sign of mass loss and filling and in 2016 an Australian expedition found the presence of warm water in front that explains what the glacier is doing what it's doing right now so we are on the
Fig. 7 Areas A-F

trajectory of a metre [of SLC] per century  ... DAMAGE doesn't take place with multi meter sea level rise it STARTS WITH ONE METER [OF] SEA LEVEL RISE. We have a lot of people living within a meter of sea level rise [and] a lot of infrastructure. San Francisco doesn't have an airport with one meter sea level rise so we have to communicate this risk and one of the difficulty when we talk about the polar regions and sea level rise is that THE [SCIENTIFIC] COMMUNITY TENDS TO BE CONSERVATIVE IF YOU'RE CONSERVATIVE YOU LOOK LIKE A BETTER SCIENTIST THAN IF YOU ACTUALLY TELL THE FACTS THAT ARE PRETTY SCARY ... sometimes we will have to move or to protect some people will be able to protect some people will have to move and it's coming with all kinds of issues because the poor populations will be affected the most and you can have massive immigration from climate change instead of violence as we experiment in today my last slide so what can we do instead of the band-aid solution which is to adapt which we'll have to do anyway is to unplug the experiment before the patient dies and avoid a commitment to multi level sea level rise and and I think that that commitment is not way ahead of us I think we have right here we already unplug a lot of the systems ... we're looking for is a world informed by science instead of Twitter ..."

(See video below for the audio/visual ... the Youtube software translated it, I added some emphasis). 

What Dr. Rignot said was in total agreement with Dr. Hansen who was quoted in the previous post of this series.

IV. Closing Comments

The movie Don't Look Up explains the dynamics we have inherited from the Bernays Era.

But Don't Look Down is the propaganda reality we are living with, and that is not a comedy.

There is a constant suicidal "look over there" discord that prevents a proper response to the "pretty scary" dynamics of our time (How To Identify The Despotic Minority - 14).
