Groundbreaking AGW-Undermining Study: Greenland’s Warming, Ice Loss Due To Geothermal Heat

‘Several Thousand’ Hot (60°C) Springs ‘All Over’

Greenland Melt The Ice Sheet From Bottom Up

A few years ago, 10 glaciologists publishing in the journal Nature Geoscience asserted that “large parts of the north-central Greenland ice sheet are melting from below” due to high geothermal heat flux forcing (Rogozhina et al., 2016).

In a new paper published in Scientific Reports, 4 more glaciologists (Rysgaard et al., 2018) report that “hot vents” (or hot springs) of geothermally-heated water underneath the Greenland ice sheet can explain localized rising temperatures and glacial melting.

Water Temperatures Beneath Greenland Reach 55-62°C (Water Boils At 100°C)

Water temperatures of these natural hot springs reach into the 60°C (140°F) range, and there are several thousands of them all over Greenland“, with observations of high geothermal heat/ice-melt locations spanning the East, West, North, South, and Central regions of this glaciated island.

It’s instructive to put these subsurface hot spring water temperatures (reaching a sweltering 55-62 °C) into perspective.

Greenland’s surface air temperature averages about -28 °C year-round, and the coastal water temperatures routinely hover around 0.0 °C (32.0 °F) during the summer.

Consider that over the last 50 years the global oceans are alleged to have warmed by “only about 0.1°C” in total (Bereiter et al., 2018).  That’s a change of one-tenth of one degree Celsius over 5 decades that climate scientists sympathetic to the anthropogenic global warming (AGW) cause claim could be heavily responsible for the change in Greenland’s glaciated landscape.

Compare this tiny 50-year accumulation of thermal change to the range or variations in the natural, on-the-path-to-boiling heated water source directly beneath the Greenland Ice Sheet.

Interestingly, the role of anthropogenic CO2 emissions in Greenland’s glacier dynamics is not mentioned in the paper.

The Greenland Ice Sheet Has Not Been Complying With The AGW Narrative

Consider these recently-determined scientific conclusions pertaining to the Greenland Ice Sheet.

(a)  Greenland was 3 to 5 °C warmer with 40 kilometers less ice area 4,000-10,000 years ago (Mangerud and Svendsen, 2017, Lasher et al., 2017, Kobashi et al., 2017).

(b) There has been no net warming of the Greenland Ice Sheet in the last 80 years (Hanna et al., 2011Zhao et al., 2016).

(c) Melted ice from the Greenland Ice Sheet has contributed only 1.5 centimeters (0.6 of an inch) to global sea level rise since 1900 (Fettweis et al., 2017), with no (zero) net sea level rise contribution between the 1940s and the early 2000s.

(d) Melted ice from the Greenland Ice Sheet contributed only 0.39 of a centimeter (0.15 of an inch) to global sea levels between 1993 and 2010 (Leeson et al, 2017).

(e) [T]he interior of the GrIS [Greenland Ice Sheet] is flowing 95% slower now than it was on average during the Holocene.”  (MacGregor et al., 2016)

(f) Greenland has been cooling slightly since 2005 (Kobashi et al., 2017).

(g) And now it has been determined that the regional locations where warming and ice-melt has occurred on the Greenland Ice Sheet can be primarily attributed to high geothermal heat flux forcing.

The scientific evidence continues to accumulate supporting the position that the Greenland Ice Sheet has not been following the modeled expectations of the anthropogenic global warming narrative.


Rysgaard et al., 2018

High geothermal heat flux in close proximity

to the Northeast Greenland Ice Stream

Abstract/Summary

The Greenland ice sheet (GIS) is losing mass at an increasing rate due to surface melt and flow acceleration in outlet glaciers. … Recently it was suggested that there may be a hidden heat source beneath GIS caused by a higher than expected geothermal heat flux (GHF) from the Earth’s interior. Here we present the first direct measurements of GHF from beneath a deep fjord basin in Northeast Greenland. Temperature and salinity time series (2005–2015) in the deep stagnant basin water are used to quantify a GHF of 93 ± 21 mW m−2 which confirm previous indirect estimated values below GIS. A compilation of heat flux recordings from Greenland show the existence of geothermal heat sources beneath GIS and could explain high glacial ice speed areas such as the Northeast Greenland ice stream.”

‘Several Thousands’ Geothermal Hot Springs ‘All Over Greenland’ With Source Water Temperatures Of Up To ~60°C  

Geothermal springs with source water temperatures above 0 °C have been found all over Greenland, especially around Disko Island in West Greenland, where several thousands of such springs have been identified.”
“However, the hottest springs, with source water temperatures of 55-62 °C are found in East Greenland at a number of locations north and south of Scoresbysund.”
East Greenland constitutes a volcanic rifted margin that forms part of the Tertiary North Atlantic Igneous Province.”
“Combining our measurements with other sites of reported geothermal activity around Greenland clearly shows that East Greenland is a hotspot. Several hot vents exist on land, with temperatures ranging from 15 to 62 °C and a tendency to increase northeastwards.”

Vertical (Bottom-Up) Heating From Geothermal Activity Beneath Greenland Are ‘Primary Processes’ Responsible For 2005-2015 Warming

Overall, there has been a gradual warming of the stagnant deep basin bottom water below 240 m depth of 0.017 °C yr−1 from 2005 to 2015.”
“[T]he gradual temperature increase during 2006–2015 and the spatial distribution of Δθ strongly indicate that bottom water temperatures increase due to a large GHF [geothermal heat flux] in the “Dybet” section. Therefore, we assume that vertical turbulent mixing and GHF [geothermal heat flux] are the primary processes behind the observed salinity and temperature change.”

‘Hot Vents’ In West, South, North, East, Center Greenland Also Observed Where Rapid Glacier Mass Losses Are Occurring

High glacier surface speeds and negative mass balance are also observed near other hot vents in West Greenland such as the Jakobshavn Isbræ (69°N) near Disko Island;”
“[T]he Narssaq bræ, Valhaltinde glacier, Nordbo glacier and Qassimiut ice lobe in South Greenland all show negative ice mass balances near the hot vent in Uunartoq (60°N);”
“[I]n East Greenland the Helheim glacier, Isertoq and Mittivakkat glaciers located near Ikasagitavaq (66°N) are losing mass, and high ice speed is also observed at the Kangerdlugssuaq glacier where a GHF [geothermal heat flux] of 70–80 mW m−2 has been recorded (68°N).”
• “In addition, a GHF value of 135 mW m−2 has been reported at NGRIP [North Greenland].”
A GHF anomaly of up to 88 mW m−2 was modeled to be located at the head of the 750-km-long Northeast Greenland ice stream.  … Our recorded GHF of 93 mW m−2 in the Young Sound-Tyrolerfjord is located in this GHF hotspot and supports their model results. Hence, this part of Greenland may play a role for the rapid basal melt located at the head of the Northeastern Greenland ice stream and its high ice speeds.”
“[T]his accumulated evidence point to active geothermal activity in the northeastern corner of Greenland and indicate that geothermal heat source may exist below the center and northeastern part of GIS.  This heat source may explain the origin of the Northeast Greenland ice stream and other areas with high ice stream speed.”

    As a geologist, I certainly believe that deep water volcanic and hydrothermal systems are what controls the temperature of our oceans causing El Ninos as well as the ocean’s multi decade oscillations.
    However, in this study, there is no mention of the Medieval Warming Period from 1000AD to 1300AD when Vikings inhabited and farmed in Greenland.

  2. ClimateOtter

    The Earth itself is providing far more to heat the ice cap than humans (*might*) have managed to do in the last 250 years- which corresponds oddly enough with the Deepest portion of the Little Ice Age.

    Greenland doesn’t seem to be noticing.

  3. Steve

    The antarctic is melting too!
    It’s those pesky little aliens living under the ice and their warm everything up technology causing it.!
    I am very worried about this because my house is only 30 metres above sea level.

  4. Bitter&twisted

    So basically the geothermal heat flux is at least 10x greater than any climate change influence.
    Makes it rather hard to predict any change in ice mass balance as a result of climate “change”.
    However I suspect it won’t stop the fraudsters and rent-seekers from trying.

    Thule Operations 1 in 2012 Spring photographed and noted the steam rising from the ice in Greenland — https://espo.nasa.gov/oib/image/Detail_of_a_steaming_sea_ice_lead_Thule_AB_Greenland

    1. AndyG55

      Must have been a high concentration of CO2 over the ice, I guess. 😉

      1. SebastianH

        I hope both of you know that it doesn’t require particularly hot temperatures for water to steam in a cold environment such as Greenland, right?

        1. AndyG55

          Well that was a non-answer, even for you. !!

          1. SebastianH

            How would you classify your reply, AndyG55?

        2. sunsettommy

          You did realize it is well below freezing at the time, Sebastian?

        3. AndyG55

          So what temperature does frozen water “steam”, seb

          Waiting for your sublime comment!

          STILL waiting for empirical proof of CO2 warming our gravity controlled convective atmosphere.

          Waiting,

          Waiting.

    Incredibly the coldest temperature ever recorded in the Northern Hemisphere was July 05, 2017 at Summit Station on GREENLAND. Additionally the mass surface ice budget is blowing away all records from the 1981-2010 averages. This was not predicted in the IPCC climate models.

    However just 6 days later (July 11, 2017), a pilot Ágúst Arnbjörnsson, during a flight from Keflavik to Portland, from a height of approximately 34,000 feet photographed steam venting from the Greenland ice field. The location is 75 km from Kulusuk Greenland.

    His image appears to show three plumes of steam rising from cracks in the glacier, which according to the blog of volcanologist Haraldur Sigurðsson, is 1.5 to 2 kilometers thick.
    This is, in all probability, signs of powerful geothermal activity from below the ice.

    Hello from a typical AGW skeptic. Playing the role of warming alarmism believer I respectfully request rebuttal of the following.

    Science of Doom’s sea level rise page assumes without specifically stating that the RCP 8.5 scenario with accelerated thermal expansion of ocean water and ice sheet melting due to atmospheric warming.

    https://scienceofdoom.com/2017/02/17/impacts-vii-sea-level-2-uncertainty/

    Skeptical Science’s Greenland Ice Loss page shows scary melting graphs and probably also assumes the RCP 8.5 worst case scenario due to atmospheric warming due to the insulating thermal resistance property of additional co2 that due to conservation of energy requires lower troposphere warming to balance with outgoing long wave IR.

    https://www.skepticalscience.com/Greenland-ice-loss-continues-to-accelerate.html

    How then does Greenland Ice Sheet melt due to geothermal undermine the alarmist position since that doctrine’s scenarios do not include geothermal effects?

    Thank you for your consideration.

    1. AndyG55

      “thermal expansion of ocean water and ice sheet melting due to atmospheric warming.”

      NO.

      The ocean’s control the atmosphere NOT the other way around.

      If the ocean is warmer than the air it will release energy to warm the atmosphere.

      If the air is warmer than the ocean , the ocean will release water vapour as evaporation to cool the air. This mechanism DOES NOT warm the ocean.

      Basically anywhere there are ice sheets , the temperature is well below zero nearly all the time. Only on rare occurrences, in the middle of summer (in respective hemisphere) do atmospheric temps get warm enough to actually melt the surface.

      RCP 8.5 is a nonsense construct based on nonsense assumptions, as there is no scientific proof that CO2 causes warming in our convective atmosphere anyway..

      1. yonason (from my cell phone)

        RE – RCP 8.5
        https://judithcurry.com/2015/12/13/a-closer-look-at-scenario-rcp8-5/

        And that’s probably much milder criticism than it’s use/misuse deserves.

    2. AndyG55

      ” insulating thermal resistance property of additional co2 ”

      Again a load of nonsense.

      CO2 does not have any insulating properties.

      If it did, it would be used in double glazing, but tests done in that industry show that CO2 is a worse insulator than normal air.

      CO2 is just another conduit for atmospheric cooling. Is absorbs a narrow band of radiation , then immediately passes it on to the other 99.96% of the atmosphere where convection takes care of the normal cooling. (radiative release time is several magnitudes SLOWER than collisional/thermalisation time)

      All radiation in the CO2 band is absorbed in about 10m from the surface, changing the CO2 concentration would lower the distance to say 9.5m, but it does not stop the normal cooling action of the atmosphere.

      There is ZERO proof that CO2 causes warming in a convective atmosphere.

      1. SebastianH

        If it did, it would be used in double glazing, but tests done in that industry show that CO2 is a worse insulator than normal air.

        And there it is, the infamous AndyG55 double glazing argument. Destroying all we know about physics in a single sweep 😉

        CO2 is just another conduit for atmospheric cooling

        Yeah, one that is slower than the usual cooling through direct radiation to space. Since it radiates in all directions and not only towards space. Physics 101.

        All radiation in the CO2 band is absorbed in about 10m from the surface

        And? Is all that radiation energy then only going upwards? How sure are you about that?

        There is ZERO proof that CO2 causes warming in a convective atmosphere.

        Physics! Not being able to easily conduct an experiment of the size that would be needed to confirm that for skeptics like you, is enough for you to believe there is no effect at all. Great 😉 So, please show us that gravity in the vicinity of our nearest star system works the same as here in our solar system? What? You can’t do that? Then gravity must be something made up! That’s how your broken record sounds like …

        1. AndyG55

          Empty on EVERY count. Poor seb

          Every statement I said was provable TRUE.

          You have made ZERO counter.

          There is ZERO proof that CO2 causes warming in a convective atmosphere.

          We are STILL waiting,

          and don’t try that vague “physics” word. because you have proven time and time again that you know NOTHING about actual physics.

          You have NOTHING, seb, and your EMPTY responses PROVE it.

          1. yonason (from my cell phone)

            I’ve made the same argument about how useless CO2 is as an “insulator.” It’s based on fact, not chatbot fiction. The physics doesn’t change based on the narrative the activists are pushing.

            As always, SebH mocks what he can’t refute. And he’ll NEVER give an actual scientific reason for anything, at least not a correct and/or consistent one.

            And speaking of consistent…

            Oh oh, did he admit that CO2 radiates in all directions?! I thought it only radiated exclusively toward the earth. I guess it depends on which lie he’s telling at the time.

          2. SebastianH

            Oh AndyG55, if “physics” is a too vague word for you, then no wonder you have no clue and claim the wildest things 😉

            @yonason:
            You too, if you knew anything about physics and the mechanisms involved, you wouldn’t make that argument. It is ridiculous and I won’t repeat for the hundredth time why that is the case.

            As always, SebH mocks what he can’t refute.

            I am mocking those who will stubbornly refuse to accept reality in face of overwhelming evidence and who try to construct a different narrative that better suits their belief system. I still haven’t found out why most of the skeptics are so confused and bring up the ridiculous arguments they do.

            btw: what would you be trying to accomplish by using CO2 as insulation between sheets of glass? Would you like to block radiation in a certain frequency band or would you like to lessen the conduction between both sheets of glass? There is no reason to use CO2 for any of those applications. That being said, it is better at absorbing and re-emitting radiation than a pure nitrogen/oxygen gas mix, all greenhouse gases are. And by that nature it is insulating the surface from space. A conduit for radiation energy, sure … but a “slow” one.

            Refute that without mocking, I dare you!

            And he’ll NEVER give an actual scientific reason for anything

            You are kidding me, right?! Why would I repeat myself in detail hundreds of times? You ignored the first hundred times, why should I expect that you’ll even try to understand the next time?

            There a FAQs for skeptics arguments out there which are perfectly fine and explain why most of your arguments are ridiculous. Ah, I forgot, you have to mock them because you can’t refute them … right?

            Oh oh, did he admit that CO2 radiates in all directions?! I thought it only radiated exclusively toward the earth. I guess it depends on which lie he’s telling at the time.

            Seriously, what is wrong with you? Normally the skeptic side is arguing that it only emits to space, when did you change your mind? I can’t remember a single instance where I would have written that CO2 radiates exclusively to Earth. I can only think of one reason why you would think that I did, you don’t understand the mechanism and imagine one single CO2 layer emitting in all directions. Is that correct? So when someone says the what’s radiated back to the surface is more than what is radiated to space, you can’t understand why that is the case. Correct? And then you post links to websites with “divine intervention” written in diagrams (or was that sunsettommy, I don’t remember).

            Anyway, good night and have fun in your fantasy physics bubble 😉

          3. AndyG55

            “in face of overwhelming evidence “

            YOU HAVE NO EVIDENCE, seb

            NONE NADA.. That is the point.

            You remain as empty of any scientific proof for ANYTHING you say, as you always have been.

            “it is better at absorbing and re-emitting radiation”

            Its remittance time of CO2 in the atmosphere is magnitudes SLOWER than its thermalisation time

            Capiche????….or does basic physics escape you AS ALWAYS.

            Proof is that it is a WORSE insulator than normal air, a measured FACT

            Measured facts are something you just HAVE to avoid , aren’t they seb, because YOU HAVE NONE>

            Off you slither, back to your fantasy, anti-science la-la-land, seb, where your so-called fizzics is a fairy-tale fabrication unsupported by any reality whatsoever.

            And we are STILL waiting for actual scientific proof that CO2 causes warming in our GRAVITY controlled convective atmosphere.

            Your manic avoidance is HILARIOUS. 🙂

          4. AndyG55

            “Normally the skeptic side is arguing that it only emits to space, ”

            Your ignorance yet again highlighted for all to see.

            CO2 emits only above 11km where the atmosphere is thin enough for thermalisation to be avoided, and the only effect is stratospheric cooling.

            https://s19.postimg.org/s6jyed10z/stratospheric_cooling.jpg

            Your grasp of even a very basic understanding atmospheric processes really is EXTREMELY POOR, isn’t it, seb.

          5. AndyG55

            “the conduction between “

            Well done seb, you finally took a tiny step forward. !!

            Convection and conduction govern the lower atmosphere.

            Now if you think just a little bit harder, you might get the next tiny step.

            Or not.

            Comprehending the basic physics of the atmosphere is genuinely difficult for you, isn’t it.

          6. AndyG55

            “if “physics” is a too vague word for you,”

            Just a word to you, seb

            All you see is a nebulous fuzz, with zero understanding.

          7. yonason (from my cell phone)

            LOL – Sorry chatbot, but if we were as wrong as you accuse us of being and you knew why, you would explain. But you don’t because you can’t; not only because you lack the ability but because we aren’t wrong – at least nowhere near as often or extensively as you.

            You don’t have a clue what “the science” really says, and no amount of calling us names will change that. What it will do, though, is showcase your ignorance and deceit. So by all means keep playing the fool for everyone to see.

            And as to the “overwhelming evidence” that humans can control climate, there is none.

          8. AndyG55

            “I am mocking those who will stubbornly refuse to accept reality”

            Self-mockery, seb.??

            Is that what you are reduced to !!

            Your brain-washed child-mind can never accept reality, so your self-mockery will be eternal.

        2. AndyG55

          “Destroying all we know about physics in a single sweep”

          Once could destroy all you know about physics with a feather duster. Your physics/science knowledge is mere dust on the surface.

          1. SebastianH

            Uuuh, I am trembling with fear … is that one of those “non-answers” you are writing about? Should we be impressed about your skills of which you have only demonstrated the trolling part yet?

          2. AndyG55

            Still no physics or science to prove CO2 causes warming in our convective atmosphere. !!

            That is you continued NON-ANSWER.

            ZERO-physics

            ZERO-science

            … just baseless brain-washed belief.

          3. AndyG55

            Only skill you have, seb

            … is EVASION!

            physics and science, not in the mix.

        3. AndyG55

          “Since it radiates in all directions and not only towards space. Physics 101.”

          You need to get past your physics 101, seb.

          You show no inclination to do so, though.

          You seem to want to remain wilfully ignorant.

          Re-emittance time is several magnitudes slower than thermalisation time.

          Sorry if that is too much for you to comprehend.

          1. AndyG55

            “We know what happens because we know what the laws of physics say would happen.”

            Quite frankly,seb, its becoming increasing obvious to everybody, that you don’t have the vaguest clue what the laws of physics say.

            They are an anathema to you, and you remain clueless.

        4. Kenneth Richard

          Physics! Not being able to easily conduct an experiment of the size that would be needed to confirm that for skeptics like you, is enough for you to believe there is no effect at all. Great 😉 So, please show us that gravity in the vicinity of our nearest star system works the same as here in our solar system? What? You can’t do that? Then gravity must be something made up! That’s how your broken record sounds like …

          Um, SebastianH, we do indeed have physical measurements from real-world experiments that demonstrate the cause-effect properties of gravity on solid objects at a continuum of heights above the Earth’s surface.

          In contrast, we have no such real-world cause-effect experimental evidence or physical measurements that shows how little or how much (if at all) water is cooled down when airborne CO2 concentrations are reduced above them in volumes of parts per million (0.000001). Therefore, the assumption that we can cool the Earth’s oceans by reducing the atmospheric CO2 concentration is no more than conjecture, as it is based on modeled conceptualizations.

          Surely you know that the physics of gravity do have cause-effect measurements, but the physics of CO2-forced ocean heating/cooling do not have measurements. So why do you pretend that these physical constructs are one in the same and condescendingly imply that those who question the CO2-forced ocean heating/cooling conceptualization are marginalized deniers of gravity physics?

          In other words, why the dishonesty?

          1. AndyG55

            “Why the dishonesty?”

            Its all he has left, is why.

            All he ever really had.

          2. SebastianH

            Um, Kenneth

            we do indeed have physical measurements from real-world experiments that demonstrate the cause-effect properties of gravity on solid objects at a continuum of heights above the Earth’s surface.

            As you are well aware, we don’t have any measurements for Alpha Centauri or any other star system. We assume that the laws of physics are the same everywhere. But, by your logic we can’t do that, we need to demonstrate that gravity behaves the same everywhere and until we didn’t do that, it’s just “modeled conceptualizations”.

            We do know the physical properties and the mechanisms. Those models aren’t based on some fantasy, they are based on what we know to be true.

            Those gases can’t just not do what they are supposed to do because some skeptics imagine it that way.

            So why do you pretend that these physical constructs are one in the same

            They are. We know what happens because we know what the laws of physics say would happen. We can model lots of mechanisms in great detail and simulate what would happen. We don’t need to drop planet size masses into the Sun to confirm it, we just needed to observe the movement of way smaller masses. Same with greenhouse gases. You learn the properties in small experiments (done a long time ago) and you can extrapolate that to bigger systems like an atmosphere. The properties and laws of physics don’t change just because it is a bigger system.

            btw: speaking of gravity, in that field a “skeptic” (if you will) indeed found a problem at high velocities. We found a better set of formulas to describe what happens in more situations. But the concept didn’t fundamentally change. However, you seem to think that there might be some unknown property of gases that completely erases their effect. I still don’t know why …

          3. AndyG55

            “Those gases can’t just not do what they are supposed to do “

            ROFLMAO.. you get more idiotic every day, seb 🙂

            Who told you what those gases were “supposed to do” ???

            That is the comment of a NIL-educated brain-washed child-mind, not someone with any knowledge of science or physics whatsoever.

            And most properties of gasses are known, just NOT TO YOU, seb.

            The fact that SebH thinks we don’t have to continually question and test EVERYTHING is a red flag.

            Does gravity behave the same everywhere? Maybe. Maybe not.

            But the point is that it doesn’t hurt to ask. In fact, when you find a “science” that doesn’t allow you to question it (like AGW and Darwinism to name just two), you are dealing with something that is more religion than science.

          “the infamous AndyG55 double glazing argument”

          Yep, we all know that DIRECT EXPERIMENTAL DATA is an anathema and an enema to you, seb.

          1. SebastianH

            If you don’t understand the mechanisms, I suppose you can use anything to support your argument that vaguely sound like it could be right. Have you found out what “rising snow levels” mean? No, not more snow like you assumed …

          2. AndyG55

            “If you don’t understand the mechanisms,”

            Which you demonstrably DON’T. Sorry that basic physics alludes you.

            Get over it.

            Yes, an El Nino will cause a small amount of warming, and limiting a study to such a short period of time during an strong El Nino, and thinking it actually means something.. that’s an AGW thing, isn’t it. !

    Over Halfway To Boiling

    In a strict mathematical sense this sort of statement does not work with the Celsius temperature, an interval scale. Switch the numbers to Fahrenheit and get a different result.
    The Kelvin temperature scale is a ratio scale because it has a unique, non-arbitrary zero point called absolute zero.
    Not the many readers will notice.

  9. AndyG55

    It should also be mentioned that all this volcanic activity is going to make a mess of any gravity based ice mass measurements.

  10. AndyG55

    OT, but this is funny, and absolutely PURE AGW crap !!!

    1. AndyG55

      I am now totally sure that these guys are writing these papers for a bit of a lark,

      …..just to see what sort of idiocy they can get published.!!

      ‘We need to change the labelling of food to increase the use-by date as these are usually quite conservative. Commercial sandwiches undergo rigorous shelf-life testing and are normally safe for consumption beyond the use-by date stated on the label.’

      That’s how people get upset stomachs: eating “half-price – use-by date is at hand” sandwiches.

      “The study also recommends reducing or omitting certain ingredients that have a higher carbon footprint, like lettuce, tomato, cheese and meat.”

      I had better omit butter and marge. Carbon Footprint and all.
      That leaves me with the two slices of bread option.

      “Reducing ingredients, such as cheese and meat, would also reduce the amount of calories eaten, contributing towards healthier lifestyles.”

      O.K. Make it one slice of bread, I’ll fold it in half.

    Groundbreaking AGW-Undermining Study: Greenland’s Warming, Ice Loss Due To Geothermal Heat

    A bold statement, at least you now recognize that it is warming and that there is an accelerating ice loss.

    Water Temperatures Beneath Greenland Reach 55-62°C, Over Halfway To Boiling

    We all probably know what you mean by this, but 50°C only “halfway to boiling” if you consider 0°C “zero boiling”. How would you describe -100 °C in terms of percentage to boiling?

    Compare this tiny 50-year accumulation [assumed 0.1 degree warming in 50 years] of thermal change to the range or variations in the natural, halfway-to-boiling heat source directly beneath the Greenland Ice Sheet.

    Well, one person is talking about the entire volume of the ocean and the other thing is a highly localized warming. Of course, those differ in magnitude.

    To illustrate the difference you can go ahead and calculate how much the entire ocean would warm on average when you increase the temperature of the top 1 meter layer by 10 degrees. Maybe put it in a unit of energy … and compare it to the mW/m² of the assumed geothermal forcing below Greenland. Good luck!

    About the melting in general: you think that the accelerated melting in the past decades will not continue for a long time, right? Or rather that it is no problem because some scientific papers show that the ice sheet could have been even “lighter” in the more distant past. Is that correct?

    1. AndyG55

      Again, seb yaps mindlessly

      SCARED of the gravity based “trend” over an active volcanic region.

      Let’s look at even that nonsense trend in perspective shall we.

      Greenland land area over the Holocene

      Greenland total ice mass since 1900.

      https://s19.postimg.org/9i1vx9lv7/Greenland_ice_mass2.png

      Sorry that big number scare the mathematically ignorant, seb. but if could spend some time actually learning than posting nonsense, you might be able to overcome your issues in time.

      And really, the moronic cherry-picking from the coldest time in 100 or so year (late 1970s.. you really are proving yourself INCAPABLE of learning

      https://s19.postimg.org/o74crkzs3/Greenland_Kobashi_2017.png

    2. AndyG55

      “Well, one person is talking about the entire volume of the ocean and the other thing is a highly localized warming”

      Yes, that is why parts of Greenland melt, highly localised warming.

      NOTHING to do with CO2.

      Your comprehension is seriously lacking today, seb, even more so than usual.

    3. Kenneth Richard

      at least you now recognize that it is warming and that there is an accelerating ice loss.

      It has been warming since the 1990s. Prior to that, Greenland cooled and gained mass for about 40 years (1940s to 1980s). So when you write that “it is warming” and the ice loss is “accelerating”, you hopefully understand the oscillatory nature of this phenomenon, and, for example, that there has been no net warming in the last 80 years, or that the ice melt contribution to sea level rise from the Greenland ice sheet has been just 0.39 of a centimeter in total since 1993.

      Do you find an 0.39 cm ice melt contribution alarming, SebastianH? During 1900 to 1940, the Greenland ice sheet contributed 1.1 cm to sea level rise (Fettweis et al., 2017), and it’s only contributed 0.39 cm more since then. Do you think this falls outside the range of natural variability? Yes or no?

      We all probably know what you mean by this, but 50°C only “halfway to boiling” if you consider 0°C “zero boiling”.

      I’ll correct it, since it’s true it’s not semantically accurate.

      Well, one person is talking about the entire volume of the ocean and the other thing is a highly localized warming. Of course, those differ in magnitude.

      Correct. But the AGW narrative indicates that the global-scale CO2 concentration is what determines the temperatures of the global-scale oceans, with global-scale meaning that we add up all the regions where the oceans are cooling (Southern Ocean and Eastern Pacific since 1979) with the regions where it has been warming and we get a net change. And when we’re talking about global-scale net change of 0.1 C over 50 years (including the regions where it’s been cooling) vs. a variation in water temperature between 55.0 C and 62.0 C at a specific location where ice is melting, which do you think is going to be considered the “primary process” in the basal melting of that ice sheet? Would you really conclude it’s the “global-scale” warming of 0.1 C over the geothermal heat flux forcing? Of course you would. That’s why you’re a believer.

      1. AndyG55

        “We all probably know what you mean by this, but 50°C only “halfway to boiling” if you consider 0°C “zero boiling””

        If you are talking about water, as oppose to other phases of H2O, then greater than 50°C is indeed “more than halfway to boiling.

        Hey Kenneth, did seb ever provide proofs for CO2 warming the oceans, CO2 browning the world, and all the other anti-science LIES he has tried to propagandised?

      2. SebastianH

        Would you please be so kind and actually calculate the temperature increase of the oceans on this globe when just the first 1m surface layers warms by 10 degrees. Can you put the assumend 0.1 degree warming in a W/m² figure and compare it to those mW/m² figures from the geothermal heat flux in Greenland?

        Do you find an 0.39 cm ice melt contribution alarming, SebastianH?

        The only thing alarming here is you guys. I’d be alarmed if the current acceleration in melting and increase in melt areas continues for another decade. Wouldn’t you be?

        https://www.eea.europa.eu/data-and-maps/figures/area-of-greenland-ice-sheet-melting-1979-2007/image_xlarge

        When you refer to Fettweis, what graph do you refer to usually? This one? http://nsidc.org/greenland-today/files/2014/05/GrnToday_Fig7_16May.png

        or that one? http://notrickszone.com/wp-content/uploads/2016/12/Holocene-Cooling-Greenland-Ice-Sheet-Surface-Mass-Balance-Fettweis-08.jpg

        Both show only a very brief time where the ice sheet actually (1970s/80s) gained mass. And again, as pointed out in the graph I linked to in the comment above, the average rate of ice loss was 286 billion tons / year since 2002. That seems to be higher than what happened in the 1930s according to Fettweis’ graph.

        I have a feeling that he doesn’t want to do this because (a) he doesn’t have the data, even though he says he does, and (b) much of his “data” comes from alarmist blogs, and he knows that citing them is anathema here.

        Or (c) you freely re-interpret everything to your liking and ignore what I write anyway. I hope you somehow see the irony of (b) … what people outside your bubble think of climate skeptic blogs doesn’t make you wonder if you should be more … skeptic about what you believe?

        1. AndyG55

          “and ignore what I write anyway”

          That’s because what you write amounts to brain-washed anti-science propaganda garbage..

          It is just your worthless opinions until you have some actual science to back it up with.

          AND YOU NEVER DO.

        2. AndyG55

          Seb,

          Greenland ice area is just a tiny amount down from its highest in 8000 + years.

          https://s19.postimg.org/ceo16fi7n/Greenland-Ice-Sheet-Briner.jpg

          The ONLY time it has been higher was during the Little Ice Age.

          THANK GOODNESS for the totally natural warming since then, wouldn’t you agree !!!

        3. AndyG55

          “I’d be alarmed if the current acceleration in melting and increase in melt areas continues for another decade.”

          That’s because you totally lack any historic understanding or reasoning.

          1979 was the coldest period in 100 or so years, both Greenland and Arctic ice were up at the levels of the Little Ice Age. (1979, always the starting point of reference for climate propaganda)

          They are the anomalies, the NH ice sheets have had just a tiny recovery from that COLDEST of periods.

          Both are still WELL ABOVE what they have been for nearly all of the current interglacial.

          There is no reason except ignorance for your chicken-little Greenland ice panic.

          Only the most incredibly dumb person would want temperatures to drop back down to those of the LIA.

          Is that you, seb??

    4. AndyG55

      “at least you now recognize that it is warming and that there is an accelerating ice loss”

      Again the lack of comprehension, and seb “just making crap up”.

      There is nothing that says there is an acceleration

      Greenland Ice mass is in fact only a tiny amount down from its highest area in 8000+ years

      https://s19.postimg.org/ceo16fi7n/Greenland-Ice-Sheet-Briner.jpg

      IGNORE the facts, seb, its all you have left.

      No sign of any CO2 warming, anywhere.

      No proof of CO2 warming in our convective atmosphere.

      Its all just an unsupportable FANTASY, seb.

    Nearly all those people are in both camps.

    Thanks. Very informative. I have filed under “The Science is Settled”.
    I am still trying to find out what happened to the great Panthalassa Ocean (?most disappeared down a hole). The Wilson Cycles are still are a mystery to me.
    There is just as much BS in Plate Tectonics as Climate Science as academic dogma squashes debate. We do not now much of our Ocean floor still but the science is settled and heretics are banished.
    Sorry for my Sunday morning rant and being off the subject.
