Explosive volcanoes can affect climate by injecting aerosols into the stratosphere.
Noah, kano is one of these "i heard or read somewhere" guys they don't provide links to the claims because they are inventing information.
CO2 in the atmosphere is measured and has been since the 50's to determine the rise in CO2 over that time, there is a proxy record that goes back much further, the ratio of isotope's in the atmosphere shows it is not rising due to volcanic activity, denier from time to time try to bring in this 'underwater volcano' chestnut, but honestly does it mater if we don't know about all the under water volcanoes if we are measuring the total atmospheric content. kano may huff and puff at my answer but he won't address this point, Volcano put out one type of Carbon isotope, CO2 from plant based sources (including petroleum) put out a different isotope to the CO2 that comes from volcanoes.

(see: volcanic misunderstanding) this doesn't change whether the volcano is on a mountain, Antarctica, Iceland or under water, all deniers really do with these sorts of question is show the limits of their own understanding. Air sampling has shown that the ratio changes are consistent with the rise in CO2 not being of volcanic origin.
This is backed by the research http://hvo.wr.usgs.gov/volcanowatch/arch...
It's always interesting to watch those like kano (there seem to be a few kano's here) who bleat about those like Noah not providing 'data' while their own questions are simply completely unsupported statements, oh the irony.
I heard some guy on Hannity's talk show today claiming 'climate change' was a ho-ax and then both of these guys went through the old BS about it's all about raising taxes, destroying capitalism, gaining 'power' and all the rest of the nonsense the deniers use instead of actually checking the data. When I hear grown, intelligent, educated men talking out of their anatomy it borders on the heartbreaking. When these people talk people believe them. Getting people to believe foolishness should be a sin...maybe it is...bearing false witness is on the list. ALL of the data so far collected point to one FACT... burning fossil fuels causes climate change
Maybe there's nothing we can do to stop doing this in the short or even medium run... it's called a high equilibrium trap... but to deny objective reality is a dis-service to the public these people are supposed to serve. They should be ashamed. Bring back the Fairness Doctrine... letting this propaganda go on is bad for our country.
Contrary to what Peggy communicated, we know very little about what is beneath the sea. We are learning. But we are nowhere near knowing enough to make a relative assessment. There was an article about a year ago where scientists studying that portion were astounded at the number of new discoveries of volcanoes. It seems they were averaging one new volcano a day, at the time.
Just today May 6, 93% of the scientists know we are part of the cause of gw. There will be greater droughts, worse winters, more cyclones, etc to do with increased air temperatures. We are taking the carbon (oil and coal) and releasing it back into the atmosphere. Like the earth was back in the days when there was no oxygen and only plants grew here. That means we die. That is simple to understand.
Nature is very powerful.Scientist believe any minute thing on earth effect the climate.By the way 3/4 of the earth is covered with water. So it is taken into account, of course.
Anything to look away from the obvious. Where do you think all the fossil fuel burning ends up?
The co2 increase is from humans, not volcanoes. This is known by analusing isotopes of carbon.
OMG If we didn't have a clue, how would we know there are underwater volcanoes We have always had underwater volcanoes and this really has no bearing on GW
I have read that possibly 85% of volcanic activity is in our oceans, which could have a huge effect on sea levels and our climate, problem is we don't have a clue about what is happening at the bottom of the oceans, I wonder if it is included in climate model calculations.
