From “Scientific” American via Reuters, proof positive that global warming is omnipotent and is intertwined into anything you choose it to be. Why, even the inner Earth bends to its will. And we all know that once the inner Earth gets out, we’re doomed, because Al Gore tells us it is millions of degrees.
Ice cap thaw may awaken Icelandic volcanoes (link fixed)
By Alister Doyle, Environment Correspondent
OSLO (Reuters) – A thaw of Iceland’s ice caps in coming decades caused by climate change may trigger more volcanic eruptions by removing a vast weight and freeing magma from deep below ground, scientists said on Friday.
They said there was no sign that the current eruption from below the Eyjafjallajokull glacier that has paralysed flights over northern Europe was linked to global warming. The glacier is too small and light to affect local geology.
“Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades,” said Freysteinn Sigmundsson, a vulcanologist at the University of Iceland.
“Global warming melts ice and this can influence magmatic systems,” he told Reuters. The end of the Ice Age 10,000 years ago coincided with a surge in volcanic activity in Iceland, apparently because huge ice caps thinned and the land rose.
“We believe the reduction of ice has not been important in triggering this latest eruption,” he said of Eyjafjallajokull. “The eruption is happening under a relatively small ice cap.”
Carolina Pagli, a geophysicist at the University of Leeds in England, said there were risks that climate change could also trigger volcanic eruptions or earthquakes in places such as Mount Erebus in Antarctica, the Aleutian islands of Alaska or Patagonia in South America.
…
He said that melting ice seemed the main way in which climate change, blamed mainly on use of fossil fuels, could have knock-on effects on geology. The U.N. climate panel says that global warming will cause more floods, droughts and rising seas.

I like your perspective. Greenland warming seems confined to the extreme south at sea level. Iceland is something like 250 km from Greenland at the closest. The magma feeding Iceland’s existence has been doing so for millennia and is associated with the Mid-Atlantic Rift. Seismicity in Greenland must be related, but if the cause of Iceland’s eruptions were warming southern Greenland now, why hasn’t it succeeded in melting the Greenland ice over the past 2,000 years? And why at sea level?
It’s worth noting there is some uplift going on in Greenland, east Greenland I think. It’s probably not any more dramatic than the uplift in southern Finland which has been going on forever. Greenlandic lifting is also probably one of those things that has only been noticed relatively recently.
Oh, spare me, it’s probably too late in the thread to post this, but…
We sailed up the coast of Cape York in 1991 and the results of Mt Pinatubo in the sky were spectacular sunsets, lots of porphry in the water, interesting colours in the water at night.
When we returned home 2,500km south, our local beach was covered with porphyry from the Pinatubo eruption, which we still have as a nice Japanese-style rock garden.
In 2006 we were sailing in islands north of Fiji and passed through an amazing huge floating field of porphyry which we later heard was an underwater eruption that resulted in a new island just where we hade made our passage.
How good’s that?
But these things happen in the areas we have named “Vulcania” all the time, and if it happens under water in 5000m, you don’t know until the evidence surfaces.
Looks like this was discussed in 2008.
Melting ice caps may trigger more volcanic eruptions

Caroline Pagli: YAOOYFM!
Tim Clark,
You have it backwards. The surge in volcanic activity did not end the ice age, but rather the end of the ice age increased volcanic activity (which is further evidence supporting the scientist’s claims).
The gist of this is that the mass of ice resting on the surface of the earth, unmoving, on Greenland and Antarctica, is not nearly as “light” as people would imagine. It is kilometers thick, covering thousands of square miles, and so has considerable mass.
It sits on top of the tectonic plates, which in turn float on a layer of magma (molten rock). At any time, at weak points in the crust (volcanoes), the pressure can build up and the magma can escape.
When a very large volume of the ice melts (such as the glaciers that covered the northern hemisphere during the ice age), for whatever reason, the change in mass resting on the continents can cause very minor shifts in the tectonic plates. This is not nearly enough to directly create a volcano, but certainly enough to shift the balance and cause many more eruptions from existing volcanoes than “usual.”
“He said that melting ice seemed the main way in which climate change[s], blamed mainly on use of fossil fuels.”
So the ice ages and interglacials, the Minoan, Roman, Medieval and Modern warm periods, and all the cold periods in between are due to the use of fossil fuels?
Actually, I think this is conjecture or speculation. Maybe science fiction is an apt description as well?

The latest theory about AGW –
The increase in global warming (and CO2) will cause a measureable decline in the IQ of people in Japan, North America and Europe; the same will not be true in India or China.
The closer to the source of CO2 production the less the IQ problem and the greater the likelyhood of Cancer, Lung, and Heart Disease.
The sky is falling! The sky is falling!
It’s the end of the world!

“We geologists will divide into two camps on this obviously very important subject.”
I disagree Peter, we are in three camps, skeptical and practical, government or academic and consultants. Us consultants say, “I think not but I could be wrong, I will be glad to give you proposal.” Lets join forces and maybe we can get some fool to give us an all expense paid trip to Iceland.
I expect the White House to blame the eruption on George Bush’s climate policies.
Iceland must have had more exploding volcanoes in the 1930s – the temperatures were warmer then
Here are the temperatures from Reykjavik (GHCN and HadCRU):

These temperatures match the AMO almost exactly.

What has this got to do with CO2 thinning icecaps leading to angrier volcanoes? Where is the evidence? Pure, speculative drivell from a bunch of rent seeking charlatans.
“We believe the reduction of ice has not been important in triggering this latest eruption,”
Then why open your mouths? Funding!
Hot magma against ice and hot magma wins eventually.
Never get in the enemy’s way while they are in the process of destroying themselves.
The global warming movements worst enemy is not us “deniers”, it is the true believers among them.
“Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades,”
and then…after that…somewhat smaller eruptions or less
frequent eruptions in Iceland….So says Mafesto!
Equine excreta!

…In the late 1700’s a Swedish scientist poking around the Viking settlements in Greenland noted that the places where the Vikings had docked their boats were under water, which showed the land was sinking. (This was notable to a Swede, for back in Sweden the coasts were rising.)…

Quite right. Some of the Thule archaeological sites in northern Greenland are now underwater. But so is Roanoke colony in Virginia. Anyway, yes, it is happening, Helsinki is rising and the Kola Peninsula on the White Sea is sinking, Australia is also doing this table-dip thing. Greenland is probably more than a single landmass ringing a bowl-shaped depression filled with ice, it’s probably many small islands and several large with multiple large outlets to ocean at a rebounded, zero-ice state. But for it to have zero ice and rebound, the entire geography would change and it would probably look more like a very large atoll of rocky islands around a shallow sea with some mountains sticking out of it.
“Does anyone on here not believe in isostatic rebound? Because places like the great lakes and Hudson bay are still rising in response to removal of the ice from the last ice age.”
Yeah, I believe that when mile thick glaciers melt, it affect geology. What is ridiculous is the idea that there are still enough mile thick glaciers around to melt to affect it again. By that I mean mile thick glaciers that survived the Holocene Optimum, which was much warmer than today and lasted thousands of years.
I don’t get the idea that these glaciers will now melt, when they didn’t before with much greater provocation.
Dark matter is based on observation. A galaxy continues to rotate at the same speed out towards it’s edge as it does just off the central hub. It takes matter to constrain it from flying apart. Observational data supports dark matter/dark energy surrounding spiral galaxies.
Dark Warming is based on model assumption. The models predicted runaway warming, and it did not happen. It’s a travesty because the observational data does not support dark warming/dark heat surrounding or hidden in Earth.
So, what do the warmers come up with? Fudged observational data to support the model.
Take as much budget allocation as you want from NOAA and GISS and give it to a worthy cause: NASA Space. Let NOAA and GISS operate with dark funding.
This may get snipped to being slightly off-topic and completely verboten at WUWT:
Will the grounding of flights over Europe help debunk the chemtrails nonsense?
Anthony, you might have found the reason why the CO2 concentration in the atmosphere has been rising non-stop… for 35 years!
Greenpeace will surely now be all over this and try to turn that fire off. It’s fossil fuel burning non-stop in there…
As for my earlier remark… it might not be Gaia’s belly button if sulfated methane comes out of this hole… ooopppsss!
schnoerkelman (08:33:21) :
I have floated an hypothesis on some blogs that it is the rate of change from one microclimate to another that precipitates vulcanism and earthquakes.
The earth’s crust is very thin compared to the earth volume. Two orders of magnitude thinner than an egg shell is to an egg.
When a cooling occurs, the brittle shell contracts from the plates over the elastic lower mantle, weakening the fault and allowing vulcanism. When warming occurs, the tectonic plate spreads, leading to speeding up of plate movement and increased heat and pressure, also leading to vulcanism and earthquakes, if the plate sticks and pops.
I see this possibility as an inertial mechanism that buffers changes, by either releasing CO2 and warming the atmosphere slightly, or releasing sulfur and particulates to cool the climate, or both. Since ice ages are 4 to 10 times more common than interglacial periods, I think the earth tends to respond more rapidly to effect cooling than to warming. Cooling appears to be more “runaway” (forced) than warming may be.
Just another hypothesis. It is unfortunate that the measure of global temperature at present appears to be manipulated, and the past measure of temperature history uncertain. Otherwise we could try to link “crustal inertia” with climate.
