West Antarctic Ice Sheet (WAIS) Could Disintegrate Within Decades

[jc456]

The last time I saw a sea level rise budget come close to being balanced was was done around 2010 when the big drop occurred.

One example from 2011:

Leuliette, E.W., and J.K. Willis. 2011. Balancing the sea level budget.

https://tos.org/oceanography/assets/docs/24-2_leuliette.pdf
---
With several improvements, recent analyses of the sea level rise budget found closure at the 0.2 mm yr–1 level
---

Another from 2018:

Global sea-level budget 1993–presentWCRP Global Sea Level Budget Group
https://www.earth-syst-sci-data.net/10/1551/2018/essd-10-1551-2018.pdf
---
If we consider the ensemble mean trends for the GMSL, thermosteric and ocean mass components given in Sects. 2.2, 2.3 and 2.9 over 2005–present, we find agreement (within error bars) between the observed GMSL (3.5±0.2 mm yr−1) and the sum of Argo-based thermosteric plus GRACE-based ocean mass (3.6±0.4 mm yr−1)

I'm not certain where you got the idea that the sea level rise budget was out of whack.

is mm feet? What was it old Al said about the oceans?

That volcanoes under the WAIS may be accelerating its collapse is not something that should make you feel any more comfortable.

 

[CrusaderFrank]

Now atmospheric CO2 causes undersea volcanoes?

Like I said, skidmark...what do you suggest that we do about volcanoes melting ice other than adapt? This is in no way attributable to anything that humans have done or are doing...if the collapse of that ice sheet is an impending catastrophe, I would suggest that we start funneling the billions upon billions being wasted by climate science into adaptation to the result of the ice sheet collapse.

This is where the non-retards point out there's no evidence for your cult conspiracy about volcanoes.

Now you'll shout "Derpderpderpderpderp but look at these volcanoes!", thus confirming your retard status.

Showing that old volcanoes exist shows nothing. Those volcanoes have been around for at least thousands of years, and they're part of the status quo. The ice happily existed along with those volcanoes for thousands of years. It's only in the past few decades that the Antarctic ice started declining.

In order for your retard theory to make sense, regional vulcanism would have had to recently increased by 100 fold in the past few decades. You've given zero evidence of that, thus all the non-retards are laughing at you.

And since that would require a grade-school level intellect to understand, you won't be able to understand it, so you'll just start screaming at people to cover up for your failure.

You are the true denier hairball...the volcanoes under the west antarctic ice shelf are not dormant...they are active...and how long do you think you can have ice constantly melting before it becomes noticeable...The ice is declining from the bottom hairball...not the top.

And since the volcanoes have just been recently discovered...we have no idea how long they have been active...nor what sort of effect has been building or for how long...it is pure denial to suggest that mankind is responsible for ice loss when the ice is sitting on top of active volcanoes...

 

[Crick]

Did all those volcanoes appear in the last century? If not, then, as Mamooth told you, they are part of the status quo.

 

[SSDD]

Did all those volcanoes appear in the last century? If not, then, as Mamooth told you, they are part of the status quo.

We have no idea when they appeared....the elevation on several of them suggest that they have been around for quiet some time...the entire area is active and we have recorded no unusual seismic activity since scientific activity became a constant down there so that suggests that they have been there, and been active all along... The melting is happening from the bottom, not the top so it is the volcanoes that are responsible...not us as much as you would like it to be so. It is simply business as usual on planet earth...we are not the end all and be all...we don't drive the climate, we don't drive volcanic activity, we don't drive tectonic activity, we are along for the ride....luckily we are the most adaptable creatures to have ever inhabited the planet.

 

[Crick]

If the volcanoes did not appear in the last century, they are not responsible for the behavior of the last century. Ocean warming has destabilized the ice shelves and the ice sheets behind them. The WAIS is going to collapse catastrophically within the next few decades and sea level will rise by meters, not centimeters. You remember. when this happens. who said it would and who said it would not.

Of course you have no idea whether that is true or not...just more bullshit pulled out of your ass. And if it does collapse, and sea level rises, it will not mean you are right in your belief that man caused it...it just means that you are a blind squirrel congratulating himself on finding a nut.

 

[CrusaderFrank]

All we know for certain is that our CO2 caused the 3 undersea volcanoes and the only fix is to surrender our freedom and property to a One World government

Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly

and this story is almost three years old. They knew nothing of the enormous cavity now found under Thwaites within the WAIS.[Giant hole in Antarctic's Thwaites Glacier: "Disturbing" discovery as a giant hole was found under Antarctica's Thwaites Glacier - CBS News] WAIS movement rate has recently been characterized as "explosive" Potentially 12 feet of sea level rise by 2100 and rise continuing through the following century at one foot per decade.

There's a good chance your children will see major coastal cities abandoned in their lifetime. But you keep on fighting to keep the coal business alive and your good friends in the oil industry pocketing their billions and billions.

FRon your lips to God's ears! I want a tropical planet!

That Manhattan-sized void under Thwaites - no volcanoes. It seems large amounts of ice can melt without the volcanic heating.

Volcanic activity under Thwaites Glacier contributes to melting

Clip: It is the geology which is responsible for sub-glacial melting. Western Antarctica is geologically active. Scientists believe there is a rift system under the ice, similar to the Rift Valley of east Africa. This rift system involves increased magma movements in the crust and possibly volcanism at the glacier base, similar to volcanoes in Iceland.

Previously unsuspected volcanic activity confirmed under West Antarctic Ice Sheet at Pine Island Glacier | NSF - National Science Foundation

Clip: They also note that volcanic activity could be increasing the rate of collapse of the Thwaites Glacier, which is adjacent to the Pine Island Glacier.

Evidence of an active volcanic heat source beneath the Pine Island Glacier

Clip: Considering the abundance of volcano-like features along the WARS, ice sheet contact with a volcanic heat source is the mostly likely source of excess 3He. Volcanism in the WARS was most active around 30 Ma before present, but there is evidence of more recent eruptions. The adjacent Thwaites glacier, which drains to the Amundsen Sea, shows strong radar returns that indicate subglacial meltwater, suggesting volcanism and high localized heat flux.

It isn't as if this were obscure, hard to find information...it is readily available to anyone who doesn't simply gobble up whatever bullshit alarmist feed them.

 

[mamooth]

A non-moron would note that there's no sign of elevated temperatures in the oceans immediately over those volcanoes. Hence, they're not melting any ice. Their heat output is so comparatively tiny, it doesn't even register in the ocean environment.

Let's run some numbers.

Latent heat of melting for water = 334 kJ/Kg

Mass of ice melting = 219 E12 kg/year

That makes 73 E15 kJ/year energy being used to melt ice.

The volcanic output of the whole planet was estimated at 5E13 kJ/year for 2001.

Satellite tots up volcanic heat : Nature News

So, the Antarctic ice melt alone would require 1400 times the global volcanic heat output of a "quiet" volcanic year.

Now, a large volcano will release much more heat, but it would be impossible to miss such eruptions. According to SSDD's theory, there would have to be dozens of Mt St. Helens scale eruptions going off every year under the ice, suddenly starting just a few decades ago, but we've never been able to detect them. Being that's a nonsensical theory, everyone laughs at it.

Off topic. If you want to complain about China's GHG emissions, start your own thread.

Deflection noted and dismissed with extreme prejudice.

So you're saying atmospheric CO2 melted the ice????

Really?

Sooooo, you're telling us that 120PPM of CO2 generates at least 73E15kJ/year.

This should be a piece of cake to show us the lab work, right?

Poor hairball....is it that you are to stupid to actually look beyond the information given to you by your high priests?...or is it more of a theological issue with you...do you think it is unseemly, or improper for a lay person to question what one of the high priests tells you? Or is it just that much easier to be a dupe?

Cleary you didn't read any of the information I provided regarding the volcanic activity under the western antarctic. Instead, you go back to an old article published before science even started looking in any real way for volcanic activity under antarctica. Your article is from 2004, scientists weren't even clued into volcanic activity under the WAIS till 2007...What a dupe..

Here, from the first source I provided:

Clip: Subglacial meltwater movement under the Thwaites Glacier was mapped with radar-based methods. The result is that meltwater production is very unevenly distributed. This can be used to calculate the geothermal heat flux under the glacier, which reaches values up to 200 milliwatts per square metre while averaging near 100 over the whole area. In comparison, the average value for all continents on Earth is just near 65 milliwatts per square metre.

Don Blankenship, scientists of the University of Texas and one of the author of a recently published study, described the Thwaites Glacier as follows: The glacier “sits on something more like a multi-burner stovetop with burners putting out heat at different levels at different locations. …


Here, from the second source...the national science foundation...you guys reference them all the time...

Clip: Tracing a chemical signature of helium in seawater, an international team of scientists funded by the National Science Foundation (NSF) and the United Kingdom's (U.K.) Natural Environment Research Council (NERC) has discovered a previously unknown volcanic hotspot beneath the massive West Antarctic Ice Sheet (WAIS).

The researchers first noted the volcanic activity in 2007 and verified its existence again in 2014.

"Our finding of a substantial heat source beneath a major WAIS glacier highlights the need to understand subglacial volcanism, its interaction with the marine margins and its potential role in the future stability of the WAIS,” they write in the Nature Communications article.

They also note that volcanic activity could be increasing the rate of collapse of the Thwaites Glacier, which is adjacent to the Pine Island Glacier.


And from the third source...also from Nature...but publshed in 2018 rather than 2004.....

Clip: Here we show geochemical evidence of a volcanic heat source upstream of the fast-melting Pine Island Ice Shelf, documented by seawater helium isotope ratios at the front of the Ice Shelf cavity. The localization of mantle helium to glacial meltwater reveals that volcanic heat induces melt beneath the grounded glacier and feeds the subglacial hydrological network crossing the grounding line. The observed transport of mantle helium out of the Ice Shelf cavity indicates that volcanic heat is supplied to the grounded glacier at a rate of ~ 2500 ± 1700 MW, which is ca. half as large as the active Grimsvötn volcano on Iceland. Our finding of a substantial volcanic heat source beneath a major WAIS glacier highlights the need to understand subglacial volcanism, its hydrologic interaction with the marine margins, and its potential role in the future stability of the WAIS.


Plenty of modern, credible evidence of volcanic activity under the glacier and in your irrational state of denial, you refer to information published several years before volcanic activity under antarctica was any more than a tiny blip on the radar.

Did you notice that the hairball's source was issued in 2004? Three years before volcanic activity under Antarctica became a topic of real interest? How deep in denial must one be to ignore information published in 2018 and rely on information published in 2004 in order to maintain the narrative in one's mind?
