If global warming is caused by humans then why does 1 volcano produce more pollution then us?

Question

One Volcano eruption produces more pollution then humans have in our entire existence.

One im not blaming volcano's two if you dont believe me watch the discovery channel. I just believe we should look for other ways to stop global warming then stopping human, yes i belive we should reduce human pollution. If the problem is to much sun light is being trapped in our atmosphere because the ice is melting why not create something to reflect more sunlight back out of our atmosphere.

Much appreciate the info Predendo, but pollution does not consist just of CO2 emission.

I thank all the people who challenge and disprove anything anybody says, because word of mouth is one of the fastest ways to gain knowledge and if people are going around telling nonfactual information it brings down the overall intelligence of our population. So help me and help others spread truth.

Answer 1

Not true, my friend:

Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1991). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons) [ ( Marland, et al., 2006) - The reference gives the amount of released carbon (C), rather than CO2, through 2003.]. Human activities release more than 130 times the amount of CO2 emitted by volcanoes--the equivalent of more than 8,000 additional volcanoes like Kilauea (Kilauea emits about 3.3 million tonnes/year)! (Gerlach et. al., 2002)

a million. what's your gender? lady 2. what's your age determination? 35 – 50 3. Do you artwork/study? artwork section time study section time 4. it is your maximum tutorial attainment? degree 5. Which do you employ as your conventional source of information? internet, BBC radio 4 6. Which do you believe is the conventional contributor to present day international warming? Human interest (which includes kinfolk Animal interest) 7. might want to human life replace depending on international warming? certain. we cant save up the renowned phantasm of 'continual boom' on finite factors. 8. overall what do you imagine the human results of international warming will be? negative 9. In finished, how a lot do you believe the united kingdom might want to spend each year on international warming mitigation? £quite a few billion. about a million% of gdp possibly. 10. What do you believe is the the finest option enhance in international temperature that human beings might want to appropriately undergo? (In °C) °C ? what number human beings? the actual reduce is a continuing 32oC above which we received't thermoregulate. i doubt it is going to ever get that warm on the poles at the same time as there is life interior the international. i dont imagine more effective than some hundred thousand human beings will live on a 6 to 10 oC upward thrust. 11. Which option do you believe human beings might want to take to mitigate the outcome of international warming? cut back our CO2 and different greenhouse gasoline emissions.advance how you could counteract CO2 emissions, e.g. boost the oceanic CO2 ‘sinks’ seize and keep greenhouse gases to stay away from atmospheric toxins. also re-sequester some co2 already emitted to the ambience to cut back to 350 ppm.. 12. Do you believe human beings have an ethical accountability to guard and keep up the lives of others, which includes different species? no, even if that's an rather good idea to finish that. 13. For question 12, clarify why you believe/don’t believe that human beings have this moral accountability: do beings on a life boat owe one yet another care? possibly no longer. yet the following, we've an ethical accountability to fix our personal mess. and a vested interest in doing so; 'mom' shouldn't style this one out for us in a way that we are able to like.

Answer 3

Volcanos are accounted for in the atmospheric models, and are inserted into forward-looking predictions. Of course later the old model has to be adjusted to account for when the volcanos actually occur, which brings current observations and new predictions back on track.

You speak of "truth" but you fail to reveal the source of your information. I assume that's because you've been misinformed by one of the professional deniers funded by ExxonMobil or the American Petroleum Institute, as listed here:
http://www.exxonsecrets.org/html/listorganizations.php

Heartland Insitute, JunkScience, etc. Unfortunately, media outlets such as Fox News present their propaganda pieces as if they were from a credible source.

Here's one account of the role of volcanos from a scientific paper in 2004:

"In the climate model, both the reduced output from the sun and the increased amount of volcanic aerosols (fine particles which reflect sunlight away from the Earth and which are injected into the stratosphere by volcanic eruptions) contribute a sizeable amount to the Northern Hemisphere cooling seen in temperature reconstructions. Their relative importance depends upon uncertain estimates of exactly how much each changed relative to a century later.

Regionally, however, solar forcing appears to have played the dominant role for the annual average over periods longer than a year or two (see figure at right). There are several reasons for this. Volcanoes do have a large impact on circulation of the atmosphere for a year or two, but the aerosols fall out of the atmosphere subsequently, resulting in little long-term effect. Furthermore, during the first and second years following eruptions, westerly air flow increases around the Northern Hemisphere during winter, when circulation responds most strongly to climate change, and brings relatively warm oceanic air over the continents. In the summer, however, eruptions lead to cooling via their reflection of sunlight, and this is strongest over the continents. The regional effects of eruptions thus tend to cancel one another, leading to a fairly uniform annual average response (see the figure).

In contrast, reduced solar output can last for decades and has similar impacts in all seasons. It leads to reduced wintertime westerly flow, resulting in colder continental temperatures. These are reinforced by cooler temperatures everywhere in the summer due to the reduced solar energy, but again the land responds more than the oceans. So during both seasons the land cools in response to solar forcing, leading to a large regional annual average response.

As shown in the figure, the annual average response to solar forcing resembles the observations much more closely than the response to volcanic forcing. The response is overall too strong, however, which may indicate either an overestimate of how much the sun dimmed during the late 1600s, an oversensitive model, or both. Nevertheless, it is clear that solar variability seems much more likely to have driven the large regional climate changes seen in historical data."

In short, the sun has more affect on climate than volcanos.

As the sun heats the earth, it's the atmosphere that holds that heat in. Man-made changes in the composition of the atmosphere are changing how much of the sun's heat that it holds.

Answer 4

Depends on the eruption, and we can't just throw stuff to reflect sunlight because it doesnt solve the fundamental problem, which are anthropogenic emissions of carbon dioxide. We risk causing more problems if this is solution is used too widely. However, it should be ok to make surfaces in human structures more reflective, though we also need to find out how much of the problem this solves.

Answer 5

Have you taken a basic science course? A volcano DOES affect the climate greatly. You need to also qualify what you're talking about when using the word "pollution." Also back up your statements with sources and data. Otherwise you sound like a sixth grader. If you are a sixth grader, you should have at hand where you are citing this point from.

Answer 6

People who don't know what they are talking about always say volcanoes produce more CO2 than people, but that is simply not true. Human activities release more than 130 times the amount of CO2 emitted by volcanoes. See the source, about 2/3 of the way down the page.

Answer 7

What do you mean by "pollution"?

Global warming is caused by greenhouse gases, mainly CO2. So instead of just saying "pollution", let's compare volcanic vs. human CO2 emissions.

"Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times."

Answer 9

But volcano eruptions have not ever garnered any votes . . . NOT even in Hawaii. Global Warming has more political power than Jesse Jackson snorting ExLax!

Answer 10

I refuse to answer any more of these stupid global warming questions... they are getting VERY old and worn... can't you people find some other issue to ask dumb questions about.?
