Evidence shows anthropogenic Co2 emissions are 100x natures, why do deniers keep pretending otherwise?
Deniers keep posting question saying things like one volcano puts out more Co2 than human do in a century. But according to USGS humans are producing 100x the Co2 that volcanic activity adds to the atmosphere.
Sorry if I wasn't clear 'modest P' but I was only referring to volcano's, I know enough to understand that emissions from the oceans, like land based emissions, are part of a cycle. Where human and volcanic emissions are additions to the atmosphere.
I'm sorry pindar I've seen you imply things out of thin air before, as you are doing here, I am talking about the difference between volcanic emissions and human emissions, but I think you actually know that, Volcanic emissions are around 300 million tons per year, human emissions are close to 30 billion tons per year a difference of around 100 times. If you truly get, that I think Co2 should be 100x less, from what I said above, then the only thing that implies is that you don't comprehend English very well.
This from the BGS addresses the figures and their sources http://www.bgs.ac.uk/downloads/start.cfm?id=432
Deniers and their fake I.D's are getting so obvious, it's quite sad really!

130 times volcanic emissions, yes, but not total emissions by natural sources. The oceans account for the largest supply of CO2 each year, some 300 Gt of CO2 v. our 30 Gt. Vegetation and soils also emit more CO2 than we do. Our emissions make up about 3-4% of total CO2 emissions each year, combining natural and anthropogenic sources.

What is key is that the natural carbon cycle tends to act as a carbon sink (absorb more than it emits). Human emissions offset this so that CO2 accumulates in the atmosphere - we do not absorb CO2 to counter our effects. If we stop emissions, then gradually the CO2 will be absorbed by carbon sinks, mainly the oceans.
Edit: All right, thanks for clarifying what you meant.
It sure is sad that the volcano myth still exists, but luckily it is not spread too often nowadays.

politicians like glenn beck do no longer think of it exists you realize. because of the fact the scientist's have hidden schedule to get extra money for furnish's and to take yet another step we will certainly keep drilling on the sea floor because of the fact it is so risk-free and we've been certain with the aid of many conservatives christians that the earth would be re regulated with the aid of bypass son do no longer difficulty approximately it and that i'm useful europe isn't freezing now and that i will probable get deleted for question answer format even in spite of the shown fact that it incredibly is the actuality

"Most of those who deny man-made climate change are Evangelical Christians who say that "God" wouldn't let it happen."
Given the number of times that we have heard that human activities produce more than 100x CO2 than volcanoes, I would say that the statement to the effect that volcanoes produce more CO2 than humans if officially a lie. I thought that lying was a sin.

Most of those who deny man-made climate change are Evangelical Christians who say that "God" wouldn't let it happen... The others who deny it are of course those who work for big-oil companies...
These guys point out to recent cold (very cold) winters as a sign that global warming is false... However, if they actually read the science section of the newspaper ore turned on a documentary channel, they'd then see how global warming is causing the current chill...
P.S. This may not be relevant to the question you asked but I recently saw a documentary on Nat-Geo titled "6 degrees could change Earthg" (narrator - Alec Baldwin) which mentioned that if the arctic ice caps continue to melt and fresh water pours into the North Atlantic, it could slow down or even stop the Gulf Stream (which keeps much of western Europe warm)... If that happens Europe can expect an ice age (albeit in a millennial - if we make it that long)...

What evidence shows that.
Your theory isn't backed up by real world observations. If man is adding 100x the CO2 then why have the CO2 levels only gone up by 1.75x in the past 100 years?
Also all that CO2 man is putting back into the air was once in the air. CO2 levels were higher in the past. The CO2 was trapped in plants that ended up as coal and oil. History shows us that CO2 in the air is not a problem.

So they can keep making monster cars, and people don't want to feel guilty driving to work in their SUVs
The current baby boomer generation have all the wealth, grew up in times of plenty and simply would rather not change the way they live; its all to hard for them. I think if you would talk to most young people they would not be in agreement. Saying that I know there are some babyboomers out there who would agree with you :)

There are pulling you chain, since most people that can do a quick search can find that is untrue.
Volcanoes do put more particles in the air during eruptions, that causes short term cooling.
Do to the number of humans, and livestock, man put out a lot of natural emissions also.

Global issues like these are now political issues. There will always be different sides fighting for their own agendas (like those who propose we're killing the earth.. and those who claim that we're not).
In politics it does not matter who's right or wrong (whether our civilization is on the line or not). The only thing that does matter in politics is who wins..
By the way though.. it's not simply CO2 that contributes to global warming. There are a lot of other factors to consider.

The deniers keep pretending otherwise because ignorance is bliss to some people.

I'm sorry but the world is seriously short of co2,we could do with at least double or treble the current levels. If you think,as your question implies that co2 levels should be a hundred times less then I'm sorry but you're wrong, at those levels all life(with the exception of microbes on black smokers) would disappear.
