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.

How much weight is on underwater volcanoes? This is not serious article, is it?
I just scrolled up, I see it is categorized as satire.
Feuillet (13:39:26) :
Paul Daniel Ash might be right saying there is some correlation between melting glacier and volcano activity, but I guess this is not the main problem.
The main issue here is whether the AGW is the one that is responsible to make such a great impact on volcano activity.
And as we now all know the ice cap have been regenerated in Arctic location, and relatively unchanged in Antarctica, the paper still assume the glacier in following area are shrinking, proving their paper consist some error that need to be noticed.

She appears to be out of her mind. To give her benefit of my doubt, has she conducted an experiment to test this?

Replied:
Off-the-wall suggestion here: how about you do some reading?
O.K.
So what is your analysis. Is the current volcanism in Iceland a direct self-sufficient result of global-warming induced activity? Is the western Antartica volcanism wholly attributable to mankind. Are you related to the authors of this paper. Just quit blowing smoke-rings out your *** and tell us what your take us. Give us some empirical figures and not just some foolish justification, at-large, of the paper,

To CRS Dr.P.H. and Dennis Hand (08:04:21) :
Quote: “It occurred to me this morning, as I read this and other articles about the eruptions in Iceland, that no has given thought to the idea that maybe what is happening in the North Atlantic is a shift in magma in the area which is resulting in a localized warming of the land in Iceland, Greenland…. and that is what is causing the melting of the glaciers. This is just speculation on my part. I am far from a scientist and definitely not a climatologist or geologist, but I do read and think about what the implications are beyond just the surface information.
One of you, who is more skilled in this area, may want to do some research on this topic.”

The idea of a change in the stress field causing seismic or volcanic activity isn’t completely nuts. See the following link as a case study:
http://www.onepetro.org/mslib/servlet/onepetropreview?id=00002558&soc=SPE
This is a small scale change in stress compared to large scale removal of ice. So, we do have solid observations to support the general hypothesis. Now, the idea that AGW=thinner ice , that’s a whole different kettle of fish on so many levels – from is AGW even a valid hypothesis to what are the local effects – we all saw how cold the US & Western Europe were this winter, despite “above normal” global temps.
Lots of comments here. But no cogent comments at Scientific Amer. One guy suggests this article is old too? I don’t know where he gets that.
At same time, I will never buy another Scientific American again, or national geographic since Murdoch got a hold of them. They have become political diatribes against nations.
Please take all your very good comments to Sci American. They should be heard there.
Enneagram (16:43:34) said…..”just wait and see. It began with St.Helen and Pinatubo”
What’s the analogy to Pinatubo? There was no blast in Iceland to inject the particulates and aerosols into the upper stratosphere as was the case at Pinatubo (up to 35km high) and Mt. St. Helens (up to 27km high). They are reporting the tops of these current pyrocumulus ash plumes at 6km which is not even as high as the pyrocumulus clouds generated by the forest fire in the San Gabriel Mountains in southern California last summer that reached 10km.
Interestingly, this eruption appears to have more in common with last summer’s California wildfire than it does with the Pinatubo eruption. Some now claim that the fires and this eruption were both caused by AGW!
Why bother gawking at lava fountains when sites like this erupt geophysical codswallop at rates worthy of Ian Plimer ?
The Icelandic volcanoes are erupting because the earths core has reached a tipping point and it’s 10,000,000°C temperature is melting the Icelandic glaciers releasing volcanoes might.
WE’RE DOOMED I SAY, DOOMED.
RUN FOR YOUR LIFE.
Sort of off topic, but I’ve been reading up on the Iceland eruption at the ‘Eruptions’ blog (http://scienceblogs.com/eruptions/). Good site for coverage of current volcanic activity, but my impression is the guy is a warmer.
He says dismissively “Remember, all the volcanoes in the world release 130 times less CO2 than the human race does each year, so even big eruptions add relatively little to the atmosphere.”
This statistic seemed way out to me. It is undoubtedly calculated with over estimates of all possible (and some impossible) sources of man made CO2 against optimistically low and incomplete souces of volcanogenic CO2. He links to a USGS site which gives references to a 1991 paper which gives a range of 145 to 255 million tons of volcanogenic CO2 per year and a 2006 paper which estimates 30 billion tons of anthropogenic CO2 per year. Seems to me that the former is low and the latter is way high. Does anyone know of any more recent and realistic estimates of volcanogenic CO2 emissions?
Global warming causing future volcanoes… I guess we are seeing insanity unfold right before our eyes… sort of like “The Shining”.
GW is also causing Guam to tip over. It’s all Bush’s fault.
I’m searching the news to find out how much CO2 is being released by this Volcanic eruption in Iceland.
Is it more CO2 than my car makes?
More CO2 than all the cars in California? More CO2 than all the cars there ever were?

Paul Daniel Ash (11:59:24),
Your ‘credible reference’ is a Scientific American reprint of a Reuters wire story. Sorry, a reprint of a Reuters wire story with no attribution is a pretty low bar for validation of anything.
My response @11:32:03 referred to George Orwell’s concern over the misuse of language. Given your response, that went flying right over your head.
The problem is the same as with those calling the Medieval Warming Period the “Medieval Anomaly.” They are attempting to minimize the reality of the well established MWP, because it doesn’t fit their CAGW agenda [“We’ve got to get rid of the MWP!” – re: Deming].
Likewise with your labeling the Holocene Optimum the “Holocene interglacial.” It is an attempt to minimize the fact that the H.O. had temperatures well above today’s. Not only during the MWP, but the Roman Optimum and the Minoan Optimum as well, when temps were even higher than during the MWP, and prior to the appearance of the first ancient SUV.
Hey, What’s up with this?

Short story:
http://www.grist.org/article/volcanoes-emit-more-co2-than-humans
More details: “Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1991). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons) [ ( Marland, et al., 2006) – The reference gives the amount of released carbon (C), rather than CO2, through 2003.]. Human activities release more than 130 times the amount of CO2 emitted by volcanoes–the equivalent of more than 8,000 additional volcanoes like Kilauea (Kilauea emits about 3.3 million tonnes/year)! (Gerlach et. al., 2002)”

But, of course if a fact does not fit with your preconceived believes it should be dismissed, ignored, or made fun of.

http://volcanoes.usgs.gov/hazards/gas/index.php
Let me see if I have this straight. In 1991 Gerlach estimates that “volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1991). This estimate includes both subaerial and submarine volcanoes, about in equal amounts.” In 2002 Gerlach et al say “(Kilauea emits about 3.3 million tonnes/year)!”.
From what I’ve seen the conventionally accepted number for active land based volcanoes is about 1500, of which on any given day 20 are actually erupting. Several studies I’ve seen from the last several years suggest the number of ocean floor volcanoes has been underestimated, perhaps vastly so. To accept the ratio of volcanic to human contribution of global CO2 that you suggest, it looks to me that we would need to conclude that several thousand volcanoes, of which some number likely higher than 40 are erupting daily, are only able to put out 70 times as much CO2 as Kilauea does when it’s just sitting there percolating. What am I missing here?
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 rising seas,
40 years of volcanic eruptions,
dogs and cats sleeping together, Clone wars,
Mass Hysteria.
So is there any evidence at all to support this claim in geological history? I would expect them to be able to show reduced eruptions during the last ice age and increased eruptions during the medieval warming period.
Mike (12:09:57)
Hey Mike, you’re a genius, and so are your friends at grist. As Dave Wendt pointed out above, If you had read what I wrote and followed the link from the Eruptions blog, you might have realized that the the quote you regurgitated from ‘grist’ is a direct sponge (word for word) off of the USGS volcanic gases information page. Wow! Unquestioning acceptance of speculation from government scientists by a warmer, what a surprise!
And just in case you weren’t aware, the type of eruption that is occurring in Iceland right now is representative of what is going on along the entire length of the Mid-Atlanatic Ridge. What’s the difference between Iceland and the rest of the ridge? It ain’t covered with hundreds to a few thousand feet of sea water, which tends to result in just a slight difference in the way the erupted materials behave!
Why is it that you folks can’t answer simple questions about the foundations of your faith. Oops, I’m sorry. I meant your opinions. All I’m asking is if someone knows of a more recent reference relevant to estimates of the amount of world wide volcanogenic CO2 emissions. I guess that’s too steep a slope for you to climb. I’ll try to be more gentle with you next time!
