Thwaites Glacier

[h=2]Scientists: W. Antarctica’s Thwaites Glacier Is NOT Melting Due To A Progressively Warming Climate[/h]By Kenneth Richard on 4. February 2019
Antarctica Has Not Warmed In Over A Century Natural Variability – Not Humans – Drives Ice Melt The most recent mass media contribution to the canon of climate alarmism referenced a study claiming that “climate change” (i.e., human-caused deep ocean warming) was responsible for the Amundsen Sea’s (West Antarctica) “rapid melting” of the Thwaites Glacier.

The front of the glacier is almost 100 miles wide (160km) and is collapsing into the sea at up to two miles (3km) a year....but I am shocked to discover there is another process that could accelerate its retreat even more.

Most glaciers that flow into the sea have what is known as an "ice pump".

Sea water is salty and dense which makes it heavy. Melt water is fresh and therefore relatively light.

As the glacier melts, the fresh water therefore tends to flow upwards, drawing up the heavier warmer sea water behind it....warm water transforms the process, according to the scientists...if you increase the amount of warm water that is reaching the glacier the ice pump works much faster.

BBC forgot to mention that a warm Volcano erupting under the glacier:

Volcanic activity under Thwaites Glacier contributes to melting

Ooops!

:3oops:

They are too busy complaining about your comment style to bother with an actual counterpoint, because they don't have one to offer.

Remember they are allergic to rational thinking because they would have to read what you posted, based on what College educated researcher has to say, thus take the easy lazy way out.....

By the way they have no argument to offer in return.....

Your post one was about THWATES Glacier, heck that is the title of your thread:

Thwaites Glacier

Your deflection to my link is hilarious since was talking about the same Glacier as your topic title.

Pine Island Glacier is not the same as Thwaites Glacier, they BOTH have a Volcano in their area.

You been drinking today?

There is no evidence of volcanic activity under Thwaites. But, if there was, what difference would it make? It's still melting.
 
Bwahahahahahahahahahahaha!!!

You drunk Calamity?

I haven't disputed that THOSE two glaciers are melting away.

You complain:

Anyone not noticing the glaciers receding is obviously a quack. You know, since the glaciers are obviously receding.

Not the SEA ICE cover for the North Pole, it stopped declining after 2007, and Antarctica is still above the 1979-2019 level. NSIDC makes that clear in their website you keep avoiding.....

Meanwhile....,

The TITLE of the post states:

Volcanic activity under Thwaites Glacier contributes to melting

See the word VOLCANIC?

In the body of the text show real Volcanic Activity:

Timing and duration of a collaps are, however, currently unknown, even though it seems widely accepted amongst scientists that a collaps is very likely. But one of the main influences on glacier dynamics were so far unknown: the geothermal heat flux from the underlying crust to the glacier ice. Until now, it has been believed that geothermal heat transfer is evenly distributed over the area of the underlying crust.

Scientists of the Institute for Geophysics of the University of Texas at Austin have now revealed that this is anything but the case. 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.

These values of geothermal heat flux are considered “significant” for glacier and ice sheet dynamics. The Thwaites Glacier is accordingly loosing large volumes of ice due to melting at its base. The geothermal heat flux is not influenced by climate changes, as opposed to melting that takes place near the coast, in the contact zone with sea water which is getting increasingly warmer.

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.

The "hotspot" has been there far longer than the melting glaciers. You do know those things do not just cool off. And, if hot lava flowed, there would be no ice on top of it. Sheesh, it's like saying global warming is due to the sun.

Well, no. The volcanoes are deep under the ice.

Volcanic activity under Thwaites Glacier contributes to melting

". . . Don Blankenship, scientist 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. … And then you plop the most critical dynamically unstable ice sheet on planet Earth in the middle of this thing, and then you try to model it. It’s virtually impossible.”. . . "

But yet there's....wait for it---ICE!

No, the hotspot has remained unchanged for millions of years. But, you know what has changed over the past 100 years?


The **** man did.

Ah. What you don't understand is that the hotspot has not been unchanged. The hotspots are along a rift and activity fluctuates along its length.

Let's say for the sake of argument that this "Ice Pump" is an actual fact.
Is this a new phenomenon that just started or not? How do scientists know?

But is it an actual fact? Britanica says:

Bottom water, dense, lowermost layer of ocean water that can be distinguished
clearly from overlying waters by its characteristic temperature, salinity, and
oxygen content. Most bottom waters of the South Pacific, southern Indian Ocean,
South Atlantic, and portions of the North Atlantic are formed near Antarctica
during the southern winter. The partial freezing of seawater over the Antarctic
continental shelf, particularly in the Weddell and Ross seas, produces salt free
ice and residual brine with a salinity of 34.62 parts per thousand and a temperature
of -1.9° C (28.6° F). The high density of the brine, 1.02789 grams per cubic
centimetre, causes it to sink. It is warmed somewhat during sinking by mixing
with other waters, but its temperature is still -0.9° C when it reaches the deep
seafloor and continues to flow northward along the bottom. Traced by this
temperature, Antarctic bottom water crosses the Equator in the Atlantic and is
observed as far north as 45° N latitude, in the vicinity of the Grand Bank.​

No mention of warm water flowing on the bottom. Sea water at -0.9°C can't melt
the glacier. Not to put to fine a point on it, the so-called "Ice Pump" and the
dopey giant BBC graphic is just so much humbug and B.S.

Ah, so all this melting over the past 25 years is due to something that has been there for millions of years, most of which time no melting occurred. It could not possibly be the result of something that has been active for--you know--the past 100 years or less: man's industrial globalism. :roll:

It has not been "there" for millions of years. As explained earlier, the "hotspot" location changes.

Only as the plates shift...which is geologically suhlohhhh. Hot spots themselves do not move. :doh

For the gazillion years the Earth's been around glaciers have melted and rebuilt. They're finding marine creatures fossils in the mountains of Montana.

Sorry, Earth has not been around for "gazillion year."
