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’m serious here.
I can’t find this article anywhere in Scientific American back to Jan 2010, and nowhere on the Reuters site as well. I think it’s a hoax, and they found out and removed it.

Saddam Hussein did have a weapon of mass distruction after all. It was oil and Britain and northwestern Europe are evidently suffering from the effects of all the Iraqi oil consumed since the Second Gulf War! Fortunately for the United States the direction of the prevailing winds mean that it is likely to escape.
There are fewer volcanic eruptions in the summer than there are in the winter. Less pressure.
See, you didn’t listen, and now we have Icecanoes.
Thanks a lot!
It is known that particular parts of the world, such as Tohoku in Japan, will have an extremely cool summer after a very big eruption (according to Dr. Junsei Kondo, Prof. Emeritus, Tohoku Unviersity). This causes, for instance, a poor crop of rice there.
We should prepare against it if the present eruption is really a big one.
Just because something CAN happen DOESN’T mean that it will happen!
I guess it’s a lesson that the alarmists need to really learn. Just because all the ice in the world can melt doesn’t mean that it will all melt.
Most of the stories of alarmism seem to think that just because something can or could happen doesn’t mean that it will but the way the stories are written they make it like just because it can it will happen!!! They seem to forget about something known as Nature that has some minor itisy bitsy wee little say in the matter.

To the alarmist CAN HAPPEN = WILL HAPPEN AND WE’RE TO BLAME.
To the actual scientist CAN HAPPEN = what’s the probability of it happening? what scenarios are there? How likely are they? What’s the Null Hypothesis? …

Problem solved then! The volcanoes will release lots of aerosols, which will reflect sunlight, and the Earth will cool back down, right?
Right!, but make the simple exercise of thinking how many suv exhausts would equal the exhaust of this volcano, it it evident that all, all the green policies are a scam. The many years of green policies, enforced by european countries, spoiled by a single burp from a “politically biased” volcano and all the clean air so hardly gotten goes to the sink, not forgetting all the jobs losses that these so smart green policies have caused and all the broken economies,the empires destroyed (like UK’s), etc.etc

Just you wait until all the volcanoes under the Antarctic ice are uncapped!
That should give us a global winter to allow the ice to build up again.
See, negative feedback when volcanoes are uncapped by melting ice.
We’ve been promised a severe northern hemisphere winter already.

You know, if a volcano blows it’s top while a glacier is sitting on top, you get a nasty mud slide (St Helens anyone?). It’s only a matter of time before such a mudslide decimates Seattle (Rainier anyone?)-let’s hope AGW melts the glaciers on the most glaciated peak in the lower 48 in time!

Is this false? If so, why?
I mean, fine if you’re content with “wow, that seems really unlikely, so it can’t possibly be true,” but you have to admit it’s not a particularly strong counter-argument…
And that’s not a particularly well thought out response.
Volcanism causes global cooling by the emmission of reflective ash and aerosols, sulphur compounds in particular.
Explain how would that end an ice age?
Definition coincide: to happen at or around the same time
Geologically speaking, what exactly is around the same time? Perhaps the volcanoes blasted off and precipitated the ice age.
Think about it.

Thanks, sorry for the trouble.
Those post modern-normal-new age-geologists need to relax, to take a deep, very deep breath of hydrogen cyanide, and only then, opine about science issues. This is a perfect recipe: they won’t worry anymore, they will inmediately begin seein opening under their feet that beautiful “gate to hell” depicted above: Their promised land of oblivion, where they will find all the warm they were preaching and longing for.
When an ice cap disappears the solid Earth deforms in response to these load changes, as observed e.g. at Glacier Bay, Alaska [Larsen et al., 2005] and at the Vatnajökull ice cap, Iceland [Pagli et al., 2007], where mass balance measurements indicate concentrated thinning at the edges of the ice cap and a total volume of ice loss of ~435 km3 in 1890–2003 [see Pagli et al., 2007, and references therein]. GPS measurements of glacio-isostatic deformation in the area have been used in the past to evaluate the underlying Earth structure [Pagli et al., 2007a]. An axisymmetric finite element Earth model with an elastic plate over an isotropic, incompressible Maxwell viscoelastic half-space with Vatnajökull modeled as a circular ice cap explains the observations well [Pagli et al., 2007]. The ice retreat history assumes isostatic equilibrium in 1890 and gradual thinning of the ice cap between 1890 and 2003. A viscosity of 8 × 1018 Pa s, assuming an elastic plate thickness of 10 km, gives a best fit to the data. Using this model, the stress tensor due to glacio-isostasy at Vatnajökull for example can be calculated. The tensor is taken as positive in tension and the pressure, P, is obtained as the mean of the normal stresses (see Pagil et al. 2008 for more information).
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.
The article did not state that global warming caused the recent eruption. The article is actually not well-written, and it’s unfortunate that the media tends to do a poor job communicating science. The media probably wanted a story, that’s all and there’s nothing more to make of it except that.
“Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades,”
So can they let us know what happened regarding Icelandic eruptions during the Roman Warm Period and the Medieval Warm Period?
John Egan (07:58:47): Does global warming cause male pattern baldness?
Yes it does and I have the “hole in the ozone layer”-like thin patch on my head to prove it! There is no other possible explanation. I haven’t looked into any, but I’m reasonably sure that my robust method of possibility nullifications might be the key to a future type of research that may be useful to potentially come up with possibilities to link AGW to all sorts of possible human health and appearance concerns. There is consensus among all of us who do this research, so we know it’s correct. Me myself and I have reviewed each other’s work and concur.
I’m not sure if I feel like an official post modern scientist after spewing all that gobbledeegook or if I just feel dirty. Perhaps some grant money and more research are needed…
