    Which Volcanoe?

    And you realize you'resetting up a logical fallacy don't you?

    (A couple of them actually).

    By showing precedence?

    Precedence does not refute the proposed mechanism.

    If you want to refute the argument, refute the mechanism.

    What you're presenting right now is little better than using "But people have always died" as a defense in a murder trial.

    A person can only die one time. This volcano had a few other major eruptions, last major eruption was in the 1800s, if i remember correctly.

    Irrelevant to my point.

    A person can only die once. People die all the time.

    Between 1821 and 1823, yes, however that is beside the point that I was making.

    Go back, re-read my post, and understand why you're tilting at strawmen.

    Addendum:
    But then again, let's apply your logic to the current situation shall we?

    Eyjafjallajokull has erupted four time.
    920, 1612, 1821-1823, 2010.
    920-1612 = 692 years.
    1612-1823 = 211 years.
    1823-2010 = 187 years.

    Clearly the frequencey is increasing, and clearly the increase in frequency is coincident with global warming, clearly it's first eruption was coincident with, and therefore cause by the medieval climate optimum, clearly the volcanoe was inactive during the little ice age, so clearly the precedence supports the notion that this volcanic eruption is as a result of Anthropogenic Global Warming.



    *Word to the wise - don't go assuming I actually agree with any of the above.

    Iceland exists because of volcanoes.

    My link quotes from the expert who has studied global warming caused volcanic activity as a specialty. This quote was made in 2007:

    (Global Warming & Volcanic Eruptions, emphasis added).

    The second portion, the evidence to show global warming damages in a lawsuit against oil companies is a different discussion.

    Way to miss the point.

    Yes. It sits on the "mid Atlantic ridge" where that ocean is spreading as molten rock moves upward. Iceland is still growing. About a decade or so it got an new island, called Sursy (or something like that) when a sub sea volcano pushed sterile hot rocks above the ocean. After they cooled, biologists began to monitor how life colonizes a sterile rocky land.

    Trippy is correct that removal of ice layer does aid a volcano erupt, at least initially, but this one has erupted many times with intervals of less than 100 years between eruptions. It is the continuing up welling of the deep hot mantle, more than the melting of ice weight that drives this periodic volcano, I am almost sure. Certainly global warming has very little to do with it.

    The effect of ice melting is more pronounced in Norway. The steep mountain walls of the fiords were once under sea water (Have fossil shells etc.) when the ice was several miles thick on top of them. They have risen 100s of meters.

    I am not a geologist, or even well read in this area, but first wife was an Oslo girl. None the less, I suspect that the sea floor spreading may have aided this amazingly rapid rise of the fiord walls. (Crustal "buckling" or something like that as the moving rocks ran into the more securely anchored Norway/Sweden mountains.)

    Somebody else who needs to go back an read my post in full, and consider what I actually said rather than what they think I said.

    I'm fairly certain that you'll find that nordic marine sequences predate the glaciations that created the Fjords by some substantial period of time.

    I am waiting for my bf who supposed to fly back from Asia to Germany this Wednesday (21/04), but I've been told that his flight is probably postponed till the earliest next week (26/4). This sucks T_T

    Is there no way to dissipate those ashes from the Europe sky? Would an artificial rain possible (to be made and to catch the ashes to the ground)? Can't somebody do something??

    Can't we just accept that nature is more powerful than us, and wait a few more weeks till our Earth has calmed down again?

    Imagine...no kerosene eating monsters pestering the air for a few days. What a wonder!

    Why don't we pray to "mother Earth" to spare us? No we can not. This is an overall fact that we depend on nature, but accepting its ultimate power wouldn't make a great contribution for long term survival.

    Then Tsunamis, then earthquakes, and storms, possible asteroids, just name it.

    But our methane farting farm monsters are still there, so what? What should we do, get the buzz out of this planet and leave the mother earth alone? We would if we could, and we would turn the whole planet a green museum. But this isn't the case. The worst case scenario, we will be destroyed by Gaia anyway, as we have been very naughty; yet we are the only species who try to understand how it works.

    MacGillivray/Baftan.

    I'm asking politely.

    Knock it off.

    If you want to debate theism, take it to the religion forum. This is Earth Science

    As I searched for other famous volcanic eruptions I came across the eruption of Mount Tambora, which made it to 7 on the Volcanic Explosivity Index. It started to 'grumble' in 1812 and peaked with a massive eruption in April 1815. The eruption sent huge amounts of dust and ash into the atmosphere, enough to actually cool the global temperature for months. That's why the following year, 1816, was known as the "year without a summer".

    Luckily for us, the Volcanic Explosivity Index for this recent eruption was just a 2, although apparently the location of Iceland in the path of many wind currents makes the spread of the ash/dust much more worrisome.

    Let's just hope that stronger eruptions aren't coming soon...

    But the whole premise Dred propose is entirely illogical (not to mention the precedence alluded to previously). One cannot become a slave to a concept because one will never learn.
