Hi everybody,

Below is a video with a thunderstorm in the volcano (move ahead up to 20 seconds).
(If I made any mistake inserting the video I will appreciate if anybody can help me to put in the rigth way)

Jeff:
While no expert, I see no reason to dispute the 200M ton figure, perhaps even as an average. A VEI 6 eruption is due a couple/century, a VEI 7 due a couple/millenium.
Where they go wrong is using arithmetic and ’sinks’ and balanced equations(a la chemical reactions), instead of fluences with Diff.Eq. in related-rate calculations. As Spencer pointed out, today’s AGW fluence is 1/24,000th that of Gaia.

Follow-up on what Philip_B said, others think a very large one is to follow: http://news.bbc.co.uk/2/hi/americas/7389682.stm

Well, based on this article,

http://www.hawaiinews.com/archives/volcano_watch/000440.shtml

the annual total of CO2 from all volcanoes is around 200 million tones, which is just slightly higher than Canada’s annual CO2 emissions. Now this article has a strong ‘warmie” bias, so, may or may not have the number accurate.

McGrats, you should remove the roof from your home, because there is simply no way you can be so clairvoyant as to be able to predict when it is going to rain.

Philip B said: “A wider point is that were that to occur, then it would be a manmade disaster, because we failed to prepare for a predictable event. Just as the current cyclone disaster in Myanmar is largely manmade through failure to prepare.”

By extension, that seems to imply ALL disasters, past present, and future could be considered “man made.” IMHO, there’s simply no way man can be so clairvoyant as to be able to prepare for all disasters.

Thanks Gary. But I’m not quite sure what he’s measuring (and it’s just NH).

Anyone know where I can get data for estimates of CRF during the holocene? (want to compare to histogram of VEI > 4, VEI > 5, and VEI > 6)

Following James, the Yellowstone caldera, 70km wide, is our own monster-VEI 8-producing volcano. Residing above a Mantle hotspot it has moved as the continent has moved over the hot spot the last millions of years.
The mother of all calderas is Toba in Sumatra 200km wide.

Remember this guys this puppy been corked up for last 9 to 10 thousands years and thats a long time. Who knows how long this these eruptions will be going on for. Maybe until it empties itself out. I bet there is another big one going in weeks or days to come. This might shut up warmers for a while.

A couple of points.

Plinian volcanic eruptions end in a final large eruptive event. We don’t know how large and what the VEI number is until that event happens, which may be weeks or months away.

The long term effect of volcanos (of this size) on climate is not the issue. The issue is their effect over a one to two year time frame. And we know from the historical record that volcanic eruptions can cause widespread crop failure and famine.

A wider point is that were that to occur, then it would be a manmade disaster, because we failed to prepare for a predictable event. Just as the current cyclone disaster in Myanmar is largely manmade through failure to prepare.

I have a friend who lives in chile, a bit away from the volcano, but i havent heard from them in days. They did say it was devastating, so I am just waiting.

How do they know how much SO2 gets ejected?

Jeff:

The paper I got my ‘20% gas required to support a the plinian column’ figure from studied the CO2 proportion and found it to vary very widely from <<5%, which might have been the mode, to 50%. I wasn’t paying attention to the other components, like SO2.
Another paper, widely quoted by AGW believers, said steady state volcanic emissions were about 200M tons per year.
For calculations then I’d use normal crustal abundance at roughly 0.03%.
Pinatubo dumped 20M tons of S02 alone into the atmosphere. I calculated CO2 to be in low G ton range using the VEI 6 estimate of cubic kilometers ejected. AGW is supposedly 6 G tons per year.
This one has already deposited up to 10 inches over 1/3 the area of Minnesota.
