Greenland surface melt falls over a kilometer to the ice sheet base. Potential -> Kinetic > than 10 powerstations combined

Hey Crick.....

Nobody cares about "misinformation". The debate ended months ago.

Where is the actual "published" paper?

They say it is published here,

"Proceedings of the National Academy of Sciences"

Cambridge written article posted this at the bottom of the article:

Reference: “Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainage” 21 February 2022, Proceedings of the National Academy of Sciences.
DOI: 10.1073/pnas.2116036119

Looked for the paper using the Information it goes right back to your article or science daily which is a copy of your article.

Pretty stupid comment. Just more lies from a "Conservative".

Significance​

Subglacial drainage systems control ice sheet flow and the quantity of ice discharged into the ocean. However, these systems are currently poorly characterized, from a lack of direct observations. This shortcoming is problematic, as changes in drainage systems can result in a markedly differently ice sheet response. Here, we present a radar-derived record of basal melt rates with colocated borehole observations, showing unexpectedly warm subglacial conditions beneath a large outlet glacier in West Greenland. The record is unprecedented because the observed basal melt rates are several orders of magnitude higher than predictions and previous estimates. Our observations show that the effect of viscous dissipation from surface meltwater input is by far the largest heat source beneath the Greenland Ice Sheet.

Lol....fully vaccinated in the US stuck on 58% for several weeks now. Indeed....who are the idiots now?

120 million Americans love their "misinformation" . Never rolling up their sleeves....and taking bows every day now btw as the vaccinated falling like flies everywhere, except of course, in the US. dOy

Waaaaay more jabbed dying of Covid now....two out of every three, in fact. Pfizer and Moderna....Wall St awake. Stocks cratering. Life Insurance companies now not paying on policies of the jabbed...."death by suicide" .

In the coming months, as the truth continues to trickle out, the deep matrix dwelling knuckle draggers will know they've been bamboozled. Hopelessly so....and I'm laughing....told the bobbleheads a FULL YEAR AGO they were being duped.
Now the data...ummm....not debatable.

So we are to depend on someone as stupid as you for information and ignore scientists that publish in the PNAS? LOL

 

[westwall]

How about some links supporting your claim here?

Just read the papers silly boi. Martha's Vineyard is FULL of the elite.

They don't seem to worried at all.

Where is the link to that allegedly published paper mentioned in post one article?

Your hypocrisy is showing up again....

And when the salt water starts lapping at their doors, they can just move to one of their mansions elsewhere. So they are enjoying that area while it exists.

Sure thing fruitcake. NO one who is part of the elite class seems to care a bit about the failed theory of AGW.

Because it is a FAILED THEORY.

 

[Crick]

With whom is it a failed theory? Certainly not with the published data on which AR6 is based.

You mean other than them including the urban heat island effect and using the low variability solar output dataset instead of the high variability solar output dataset used by the team in charge of NASA’s ACRIM sun-monitoring satellites.

 

[Crick]

Let's go down the same path I just went with good ol' Gunny. Why should the UHI heating not be included in an effort to ascertain the average temperature of the planet? As to solar output, check out this graphic. Note the magnitude of solar changes.

Gee I honestly showed in POST 11 that there was no working link to the paper, even used the search for it using the papers headline it went back to the article posted instead.

Now it suddenly works as the link is active and can find it at PNAS using the details in the article this morning.

I find this section funny as this isn't smart thing to state:

The record is unprecedented because the observed basal melt rates are several orders of magnitude higher than predictions and previous estimates.

That much abused word "unprecedented" shows up that covers a tiny time frame.

Now go look at the proposed publishing date on the now available paper you will hopefully realize why it wasn't available yesterday.

It is clear that YOU didn't read the paper yesterday since it wasn't available then.

The papers don't support the AGW conjecture anyway and with a tiny time frame in the study covered not going to spend a lot of time on it.

Greenland easily survived the Eemian interglacial period that was much warmer with sea level several meters higher than now and Humans too.

Once again have to inform your tiny memory bank in your small head that I am a Freethinking Independent, your boring partisanship attacks is a sign of small brains that you exhibit so frequently.

How old is this chart......

 

[skookerasbil]

Again.........all the nonsense posted up by the climate alarmists.......where is there any evidence that anybody is caring outside internet community forums?

Oh..........and the matrix dwelling progressives have failed to recognize that the "fully vaccinated" % has been stuck at 58 for weeks. 58%

Why?

Because 120 million Americans embrace the shit out of "misinformation".

That didn't address what I wrote. Including the urban heat island effect and using the low variability solar output dataset instead of the high variability solar output dataset is how they reached their conclusions. An opposite conclusion is reached if the urban heat island effect is excluded and the high variability solar output dataset is used.

But if you want to use your graphic you can use it to explain which factors were responsible for temperature swings before industrialization.

If you want to see climate fluctuations you have to look at the polar regions as that's where the most changes are seen. CO2 did not cause any of these temperature fluctuations. Using your graphic, tell me what caused these fluctuations in temperature.

 

[ding]

Because it is disingenuous to attribute that effect to CO2.

 

[ding]

Noted. Now explain how these temperature fluctuations occurred without using solar output.

Guess who????

 

[Flash]

The vast majority of the meltwater from the surface of the Greenland ice sheet descends through fissures and cracks to the base of the sheet over a kilometer below. The gravitic potential energy as well as the friction experienced by the flow is converted almost entirely to massive amounts of thermal energy that is melting the ice sheet from the bottom at a tremendous rate.

Accelerating melt rate makes Greenland Ice Sheet world's largest 'dam'

Researchers have observed extremely high rates of melting at the bottom of the Greenland Ice Sheet, caused by huge quantities of meltwater falling from the surface to the base. As the meltwater falls, energy is converted into heat in a process like the hydroelectric power generated by large dams.
