Another story about global warming causing volcanoes…

Maybe Not. If you consider the WUWT “reference pages”, there isn’t any attempt to quantify volcanic activity which is a significant factor Climate.
Including plate tectonics and volcanic activity is logical as it can directly impacts climate and weather patterns for years.
Tall ask I guess but here are a few links to some of the event monitoring:
– Threat monitoring (note Long Valley Caldra): http://volcanoes.usgs.gov/observatories/calvo/
– Earthquakes: http://earthquake.usgs.gov/earthquakes/map/#%7B%22feed%22%3A%221day_m25%22%2C%22search%22%3Anull%2C%22sort%22%3A%22newest%22%2C%22basemap%22%3A%22grayscale%22%2C%22autoUpdate%22%3Atrue%2C%22restrictListToMap%22%3Atrue%2C%22timeZone%22%3A%22local%22%2C%22mapposition%22%3A%5B%5B-60.93043220292333%2C-279.140625%5D%2C%5B83.31873282163234%2C79.1015625%5D%5D%2C%22overlays%22%3A%7B%22plates%22%3Atrue%7D%2C%22viewModes%22%3A%7B%22list%22%3Atrue%2C%22map%22%3Atrue%2C%22settings%22%3Afalse%2C%22help%22%3Afalse%7D%7D
The link between climate change and volcanism is still poorly understood. Many volcanoes do not seem to have been affected by it. Nor is it a particularly pressing concern today, even though we face an ice-free future. It can take thousands of years after the glaciers melt for volcanic activity to rise.
Where is going to be “ice-free” in the “future”?
I think the operative phrase here is “is still poorly understood”…
If they don’t understand what is going on, how in the world can they model it (OK, rand(n)…)…
Why don’t they just be truthful and say “please send more money”…ok, expecting the truth is a bit of a stretch….
Reminds me of a joke my Dad told me when I was in college (probably only half-joking…)
Son: No mon, no fun, your Son….
Dad: Too bad, so sad, your Dad…

What’s the deal with people not living in reality.
It’s the Sun, Reconstructed TSI chart and world volcanic activity match up don’t you think??

BTW how do you post pictures, I have nobtabs to do so, thanks.

I like the idea that the end of the ice age was “generally quite favourable” to human life. What aspects were less favourable? The lack of ice at the equator for drinkies, perhaps? This article seems science-free, with its words like “bizarre”, “strange”, “brutish”, and the concept of ice being “heavy”! I also wonder where the author got the idea that Antarctica is losing 4b tons of ice annually?
Peter, I imagine the sea level rise must have made some groups of people move away from rising waters. When I look at today´s bathymetry I wonder if we may not find archeological ruins a few meters inland from where the beaches used to be? A sea level rise like they had must have been the origin of the Flood stories?

It doesn’t matter, what if volcanos, earthquakes, extinctions, migrations, deaths, sea level changes, heat, cold, floods, drought, hurricanes and tornados are all made “worse” by global warming. Global warming / climate change is natural until the A appears in front of it.
Stop accepting the bogus implied link to man, it gives the alarmists undeserved credibility. Events, however tragic, that have a natural cause are irrelevant to this debate.
Make these fools state explicitly that the cause is AGW – then ask them how they know.

Ice sheets are heavy. Each year, Antarctica’s loses around 40 billion metric tons of ice.
Does anyone know how much of that ice loss was CAUSED by volcanic activity?
Discovery – Jun 9, 2014
Hidden Volcanoes Melt Antarctic Glaciers from Below
Antarctica is a land of ice. But dive below the West Antarctic Ice Sheet, and you’ll find fire as well, in the form of subglacial volcanoes.
Now, a new study finds that these subglacial volcanoes and other geothermal “hotspots” are contributing to the melting of Thwaites Glacier, a major river of ice that flows into Antarctica’s Pine Island Bay. Areas of the glacier that sit near geologic features thought to be volcanic are melting faster than regions farther away from hotspots, said Dustin Schroeder, the study’s lead author and a geophysicist at the University of Texas at Austin.

National Geographic – November 18, 2013
The new volcano’s discovery was accidental. In January 2010, scientists set up a series of seismometers, or earthquake detectors, on Marie Byrd Land, a highland region of West Antarctica.

There is a volcanic field in Germany which seems to erupt after the ice-load is lifted. The East Eifel volcanic field
Laacher see erupted with a VEI 6.0; 12,900 years ago (interesting Younger Dryas-type date) which formed a large caldera lake.

No the Laacher See erupted about 200 varve years or tree-ring years before the onset of the Younger Dryas.

Also there wasn’t any ice sheet nowhere near the Laacher see. You’d have to go as far north as central Sweden for that. I’m trying to fgure out if the periodic active Eiffel periods do keep pace with the glacial/interglacial cycles. It could be.
Also interesting why the Volcaism in the Massif Central in France seem to have the same cycles, maybe.
Oh and one of the more important volcanic traces are found in the ice cores of Greenland.

As I had posted on WUWT a few years ago, I wonder whether the quiet sun, such as we are now experiencing, does not somehow trigger a higher level of volcanism. No, I offer no ideas how this could be causation rather than correlation (even if it IS correlation), but that’s my story and I’m stickin’ to it. Maybe we could call it the Madman Theory. : )

Increase in solar wind speed and energy over the weekend and Japanese volcano erupts, more activity in Iceland, eruption in Russia and earthquake in Indonesia. Coincidence? Of course admitting that the sun does this just leads you along the path of what else it can affect and the collapse of the CO2 myth.
From the National Post Is it volcano season? From Japan to Iceland, scientists probe the reasons why there are so many eruptions lately
Eruptions caused by climate change
In recent decades, it has become apparent that the consequences of planetary ice loss might not end with rising sea levels. Evidence has been building that in the past, periods of severe loss of glaciers were followed by a significant spike in volcanic activity.
Around 19,000 years ago, glaciation was at a peak. Much of Europe and North America was under ice. Then the climate warmed, and the glaciers began to recede. The effect on the planet was generally quite favourable for humankind. But, since the mid-1970s, a number of studies have suggested that, as the ice vanished, volcanic eruptions became much more frequent. A 2009 study, for example, concluded that between 12,000 and 7,000 years ago, the global level of volcanic activity rose by up to six times. Around the same period the rate of volcanic activity in Iceland soared to at least 30 times today’s level.
There is supporting evidence from continental Europe, North America and Antarctica that volcanic activity also increased after earlier deglaciation cycles. Bizarrely, then, volcanic activity seems — at least sometimes — to rise and fall with ice levels. But why? Again, this strange effect might come down to stress.
Eruptions cause by the melting of ice
Ice sheets are heavy. Each year, Antarctica’s loses around 40 billion metric tons of ice. The sheets are so heavy, in fact, that as they grow, they cause the Earth’s crust to bend — like a plank of wood when placed under weight. The corollary of this is that, when an ice sheet melts, and its mass is removed, the crust springs back. This upward flexing can lead to a drop in stress in the underlying rocks, which, the theory goes, makes it easier for magma to reach the surface and feed volcanic eruptions.
The link between climate change and volcanism is still poorly understood. Many volcanoes do not seem to have been affected by it. Nor is it a particularly pressing concern today, even though we face an ice-free future. It can take thousands of years after the glaciers melt for volcanic activity to rise.
Yet while it may not be an immediate hazard, this strange effect is a reminder that our planet can respond to change in unforeseen ways. Contrary to their brutish reputation, volcanoes are helping scientists understand just how sensitive our planet can be.
