Do the Valcanos cause more global warming than humans do??

Question

I mean, the valcanos produce so many gases and in so much bigger amounts than we could, if we wanted to??

Answer 1

An honest scientist would have to say they don't know.

They are just now discovering undetermined levels of volcanic activity under the oceans which covers about 2/3rds of the earth.

Oceans are the largest reservoirs of CO2 - when cool they absorb the heavier CO2 but when heated oceans release CO2.

Apparently no one here can explain this temperature difference of about 10 degree F - ON THE SAME LATITUDE!  I have never heard any intelligent explanation for this anomaly from anyone, even the best scientific minds.

Answer 2

No. In fact, volcanic eruptions have the opposite effect--though it is short term.

When a volcano erupts, the main thing it throws into the atmosphere is a lot of very fine dust and ash. This can stay in the air for months--even a year or two. While it does, it blocks part of the sun's heat and actulally can cool the Earth a little bit.  Of course, this doesn't last--as soon as the dust settles or is washed out by rain (as I said, this can take a year or two) the cooling effect ends.

Answer 3

no global warming is caused by 90 % anthroprogenic causes

which are human causing

mainly in the first world

which means america, europe and japan are main contributors america being the most

humans burn WAY more fossil fuels than volcanos

things that you dont think contribute do

like leaving lights on, things plugged in when not using them, too much heat, and the obvious one driving

i took a course on global warming

Answer 4

No, volcanoes are not a major source of carbon dioxide. All the coal and oil burned in the world each year emits much more carbon dioxide that all the volcanoes in the world do each year. But you frequently hear people who do not know what they are talking about saying the opposite.

Answer 5

yes ive been campaigning to rid the world of volcanos 4 a decade

Answer 6

no

Answer 7

Yes but that is not a reason to pollute your home-earth. Volcano's will get much worse if GW happens as the pressures change because of the extra amount of water in the oceans and seas.

Today here is what we know:  many of mankind’s advancements cause earth surface to warm, destroy the ozone layer, kill off endanger species, heat cities, and in some way cause more destruction.  Blacktop (roads and parking lots), buildings, air pollution (causes lung and other diseases), deforestation, duststorms (which increase hurricanes and cyclones and cause lung diseases), fires (cause pollution, mud slides, and deforestation), refrigerants (like CFC's), solvents (including benzene destroy the ozone layer raising skin cancer rates) and plastics; cars, airplanes, ships and most electricity production (causes pollution including raised CO2 levels) are human problems we need to fix to keep life on earth sustainable! That is why I founded CoolingEarth.org, a geoengineering web sight. The federal government needs to adopt a pollution surcharge to balance the field and advance new technologies. We must pay the real price of oil (petrochemicals) including global warming, cleanup and for health effects. But with that we must understand we have never seen what is now happening before. CO2 has never lead to temperature change, but temperature change has led to increases in CO2. The models have to be made as we go along with little evidence! The result is:  change is on the way, we just do not know what changes. But again adding a small amount of CO2 to the atmosphere enlarges the earths sun collection causing warming; increase water in the atmosphere and they form clouds cooling earth but causing flooding. Even natural events are warming earth and causing destruction. The sun has an increased magnetic field causing increases in earthquakes (more destruction), volcanoes (wow, great destruction), and sun spots. Lighting produces ozone near the surface (raising air pollution levels). But humans have destroyed half of the wetlands, cut down nearly half of the rain forest, and advance on the earths grasslands while advancing desertification which increases duststorms. The USA Mayor's have taken a stand and I believe are on the right track, we can have control and can have economic growth. With the peak of oil in the 1970’s, the peak of ocean fishing in the 1980’s, humans must stop procrastinating and make real changes to keep earth sustainable including in the energy debate, finance and regulation. The sun is available to produce energy, bring light to buildings and makes most of human’s fresh water. Composting is the answer to desertification. New dams are the answer to fresh water storage, energy and cooling earth by evaporation, we need many small one all over (California needs 100 by 2012 and has not even started).

President Bush has made a choice of energy (ethanol) over food and feeding the starving people around the world; this is a choice China has rejected.

Answer 8

According to volcanologists, no (I trust volcanologists more than I trust climatologists).  People emit more CO2. Volcanoes are responsible fro about 200 million tons of CO2 annually and people emit 26.8 billion tons of CO2 annually. There are spikes in Volcanic output, but that usually leads to a temporary global cooling due to sun blockage.

Answer 9

Valcanoes cause more global warming than humans

its a total no-way

they are few and they are naturally producers of those gases

we are not natural producers and we produce way too much for volcanoes to compete with us

Answer 10

No.  You're right when you say that volcanoes produce more gas than we can... at once.  However, with all of us put together, we create a lot of exhaust and add a lot of carbon dioxide to the environment.  Nonetheless, Global Warming would happen without human interference- we can't change the sun!- but humans, combined, create a much more colossal amount of bad things for the Earth.

Answer 11

It's not even close.

Volcanos are few and far between, whereas there's more people than you can shake a stick at. But, on a more technical note, as heat escapes from below the earth's surface through a volcano, much of it radiates into space, and therefore the earth may actually be cooled by the action of volcanos.

Answer 12

No.  This is flat wrong.  Proof:

"a far greater amount of CO2 is contributed to the atmosphere by human activities each year than by volcanic eruptions. T.M.Gerlach (1991, American Geophysical Union) notes that human-made CO2 are dwarfed the estimated global release of CO2 from volcanoes by at least 150 times. "
