Volcanos vs anthropogenic global warming
Another stupid climate change denialist troll trick is to point out that volcanos also emit carbon dioxide and therefore volcanos, not human activity, are the cause of the current climate change crisis. While vulcanism has shaped the climate during earth’s history, it is not a significant contributor today. Human activity-associated CO2 generation dwarfs volcanos. Again, Google is your friend:
“Volcanic eruptions are often discussed in the context of climate change because they release CO2 and other gases into our atmosphere. However, the impact of human activities on the carbon cycle far exceeds that of all the world’s volcanoes combined, by more than 100 times.
“To put it in perspective, while volcanic eruptions do contribute to an increase in atmospheric CO2, human activities release an amount of CO2 equivalent to what a Mount St. Helens-sized eruption produces every 2.5 hours and a Mount Pinatubo-sized eruption twice daily.
“The most significant eruptions come from super volcanoes like Yellowstone or Mount Toba, which erupt very rarely, about every 100,000 to 200,000 years or more. Yet, the total annual CO2 emissions from human activities are akin to one or more Yellowstone-sized super eruptions occurring every year.”
volcanos are not driving climate change
-not that such driving is impossible. Aside from the great oxygenation event, the worst mass extinction of all time (end-Permian) was apparently caused by CO2 from the massive outpouring of lava that created the Siberian traps.
Of course, geology can go the other way, too. Although CO2 emissions from the volcanos that result from subduction of oceanic tectonic plates under continental plates is roughly balanced by CO2-consuming weathering of the exposed rocks, there is occasionally a collision between two continental plates. The Tibetan plateau and surrounding mountains were uplifted by the collision between the Indian and Eurasion plates, without a single volcano. You can say that the 30 million year ice age that we are in (the polar ice caps never completely disappeared, despite fluctuation) is all India’s fault.
@rick,
” the worst mass extinction of all time (end-Permian) was apparently caused by CO2 from the massive outpouring of lava that created the Siberian traps.”
How many humans were on the planet then? To quote my own post: “While vulcanism has shaped the climate during earth’s history, it is not a significant contributor today.”

you could say that. in fact you did. and i should have found it interesting. instead i found it trivializing.
Joel is quite right. Blaming volcanoes..or continental drift… for global warming is a measure of stupidity..though i get yelled at around here whenever I call something stupid. it doesn’t play well in Peoria.
And that is the problem. Global warming is now. It is serious. and the liars are making the ill informed stupid. all for money, I think. but sometimes i wonder if there isn’t something deeper afoot..then i sound like a religious nut conspiracy theorist: there is something that lurks in people that enjoys other people’s suffering, and seems to be always and forever around seizing the corrent big story and preying on people’s laziness and greed and fears and latent hatreds to turn it into maximum human misery, or just mindless cruelty and destruction…for pleasure.
but then, I don’t want to distract from the real problem with my own distracting “let’s talk about something else” -isms.
instead of sitting in our gentleman’s club talking uselessly about the days news… we should be storming the congress demanding we DO something. oh? we tried that? how about…?
A bit of humor is a good thing. Because the fact is that phenomenological warming, and the theory behind it, are so well established that people who deny anthropogenic global warming are impervious to reason or evidence. Live with it.
On the other hand, providing context may encourage young people to pursue education in both adiabatic lapse rate and the quantum mechanics of molecular vibration modes, both of which are necessary to really understand global warming.
rick
encouraging young people to pursue education in … would just produce more gratuates who don’t know what they are talking about. even if you know what you are talking about, which i doubt, you are not helping anyone understand global warming.
Yell . . .
Yes, that was then, this is now and that is quite the word salad …

Here is an alternative to how/what is warming the ecosphere.
Earlier he posed data about ocean warming excess to warming from atmosphere.
@paddy,
I don’t see how any of this bafflegab explains the abrupt increase in global warming of the last 50 years and why it follows so closely the rise in atmospheric greenhouse gases.
@paddy,
Hmm. I’m not the only one who is skeptical:

It was 96 degrees in the neighborhood i live in on May 6th, 1906.
If that doesn’t jive with your template, delete it.
OH! Look! Over there! Some dumb (white) broad’s not wearing underwear!
@skeptic,
The temperature on May 6th, 1906, is weather, not climate. Learn the difference. Meanwhile, stop trolling AB.
apparently my earlier comment discussing the difference between “skeptic” and “willful ignorance” got thrown out with the bath water.
