You might have a point, except:

In the United States, fifty to 100 years ago nearly every residence was heated by the burning of coal. Trains plied back and forth on steam provided by the burning of coal. The coal mines of West Virginia, Virginia and Kentucky worked three shifts a day, seven days to provide coal for the iron and steel industry. Many cities were so inundated daily with coal soot that it was impractical for a man to wear a white shirt to work.

Today, the only major consumption of coal is by the electrical power plants, and those are closely monitored and filtered to reduce the release of pollutants. The air-borne particles of yesterday and today are being cleansed by the natural rain cycles.

The auto and truck industries have taken great pains to reduce the pollution of their exhaust.

And more CO2 is produced by natural sources than any man-made activity. There may be some global warming... consensus is one-half degree F. in the past 40 years... but I submit it isn't man's doing entirely, as those who would profit greatly by a hysterical response would have you believe.

Two bright copper pennies worth.

Soot and other pollutants are not the same as CO2. The automobile industry has not been able to reduce the CO2 emmissions. The only way to reduce it is to burn less fuel. Some automobiles are high effencicy, but the number of automobiles on the road just keep increasing, as does the average number of miles being driven. Coal and natural power plants also contribute. No matter how many pollutants are cleaned from the talipipes and smoke stacks, CO2 continues to be released. This is responsible for the majority of CO2 that is being released. Natural CO2 is way less.

The sources of C02 and the carbon cycle on earth isn't well understood yet.
Just did some quick googling for data.
Global Warming: A closer look at the numbers

Not sure where they get their data and I'm not gonna do the research on it, but it says the baseline PPM is 288m. Natural additions are 68m, and manmade additions are 11m. So I'm not entirly sure where you're deriving your conclusions from Brownout, but it's not from real world data.

Monte Hieb worked as a chief engineer for the West Virginia Office of Miner’s Safety. He is not a climatologist by any stretch of the imagination. He hasn't published any peer reviewed papers on climatology at all. His "mining" connections make him a suspect source at best.

You don't know where the data comes from. You can't verify it's correct or not. But you're sure that I'm not using "real world" data, because this junk form unknown sources says so.

OH, I forgot, if it's on google, it MUST be true. Unless that is, if you disagree, then it must be false.

We should only believe data if it comes from unknown sources. But of course, if NASA and the Department of Energy puts up facts and data, you should ingore it completely.

Before humans began emitting significant amounts of carbon dioxide into the atmosphere, the atmospheric uptake and loss of carbon dioxide was approximately in balance. "Carbon dioxide in the atmosphere remained pretty stable during the pre-industrial period," said Gregg Marland of Oak Ridge National Laboratory in Oak Ridge, Tenn. "Carbon dioxide generated by human activity amounts to only about four percent of yearly atmospheric uptake or loss of carbon dioxide, but the result is that the concentration of carbon dioxide in the atmosphere has been growing, on average, by four-tenths of one percent each year for the last 40 years. Though this may not seem like much of an influence, humans have essentially tipped the balance of the global cycling of carbon. Our emissions add significant weight to one side of the balance between carbon being added to the atmosphere and carbon being removed from the atmosphere.

"Plant life and geochemical processes on land and in the ocean 'inhale' large amounts of carbon dioxide through photosynthesis and then 'exhale' most of it back into the atmosphere," Marland continued. "Humans, however, have altered the carbon cycle over the last couple of centuries, through the burning of fossil fuels that enable us to live more productively. Now that humans are acknowledging the environmental effects of our dependence on fossil fuels and other carbon dioxide-emitting activities, our goal is to analyze the sources and sinks of this carbon dioxide and to find better ways to manage it."

NASA - The Human Factor: Understanding the Sources of Rising Carbon Dioxide

Pommie, natural additions mean increase in CO2 levels that are attributed to natural sources.

And technically both articles are suspect. Because they didn't provide any reference to where they got their information from. Ask two different scientists you'll get two different answers, I'm not sure where the 'scientists agree' or what data sets to believe. A quick quote from a Nasa site that the article you posted referenced for further reading was.

Current estimates of human-produced carbon dioxide emissions into the atmosphere are based on inventories and estimates of where fossil fuels are burned and where other carbon dioxide-producing human activities are occurring. However, the availability and precision of this information is not uniform around the world, not even from within developed countries like the United States.

Anyone that outright believes without a lot of skepticism that scientists really have a handle on this either way right now is seriously mistaken.

And? Do you reject all science unless they can measure every quantity without tolerences? There is a huge body of work in this field, including cores taken from ice sheets, fossels, radio active methods, correlation with historical data, etc. We blow off scientific work on the Earth's health at our owp peril! None of the deniers has credible evidence to the contrary. They only have attempts to deny and discrdit.

BTW, you can crap-can the Hieb article as soon as he makes water vapor a green house gas. LOL! Credibility-zero!

I think ke5frf post stands on it's own. I agree with him 100% but I do have words to add for myself =)

Okay, lets start after my last post =P

And? Do you reject all science unless they can measure every quantity without tolerences?

Absolutely not, but EVERY article I have read concerning global warming has failed utterly to mention the fact that there is variability, the quantities mentioned are statistically derived from narrow data sources and make broad reaching statements, virtually no two of which agree.

There is a huge body of work in this field, including cores taken from ice sheets, fossels, radio active methods, correlation with historical data, etc.

That huge body of work contains all of the sketchy left and right wingers as well as true scientists that go for raw data an unbiased calculations.

We blow off scientific work on the Earth's health at our owp peril! None of the deniers has credible evidence to the contrary. They only have attempts to deny and discrdit.

No one here is a denier, to deny global warming is occurring is idiotic. No one is blowing off scientific work, but the scientific credibility goes out the window when fearmongers warn we need to immediately stop burning all fossil fuels reduce the worlds human population by a few billion and go back to the stone age.

The only thing I am attempting to deny and discredit is one thing and one thing only. The human race as a whole, including all scientists on this planet, including every theory and every variation of that theory concerning the true cause and effect relationship of man and natures effect on the carbon cycle on this planet is at BEST just a guess. The science itself has many years to go.

Good science always includes a discussion about variabilities. You find a good example in the articles I linked referenced for further reading, and then turn right around and state that every article fails to mention variability. Even bolded and underlined the word "every." How do you post a direct quote that mentions variability, then deny any such thing exists? You don't know if you're coming or going on this subject. Only the literature that attempts to discredit the science utterly fails to discuss the vaiability of their own data.

In fact, the science has done a good job of showing the variables. But as all good science does, it looks at the evidence and comes to the very best conclusion based on the evidence. Yes, there is alot of study left to do; however, that does not discredit all of the science done to date. It's not political; it's not left or right; it's not about a bunch of atheists or achedemia using a false issue to acquire government funds. It's not fearmongering. It's a warning about how we are affecting the climate by burning fossel fuels. It's a warning we should head, becuase we should leave something better to our children than we are on track for.

This discussion is only going around in circles. I have yet to see any evidence that the science is wrong. I only see one wrong, unsubstianted rant after another about the science of climate change, and the scientists who have worked hard to inform the public of the dangers of ignoring our impact on the world we live in. Science serves mankind. Go ahead and rant all you want. If I chose not to continue this rediculous roundabout discussion, it's not because you've done anything to change my mind. It's simply because the discussion has become a waste of my time.

heres the dilemma I see with this whole global warming situation.
It depends on where you look and what you factor toward 'green house gas' production sources.
With a quick and unbiased on line search you will find that human influenced green house gas production numbers supposedly have risen by around 200% in the last 50 years or so.
But depending on what information source you chose that relates to any where from 10% of the worlds natural and man made combined numbers to about 90% of the worlds natural and man made combined numbers.

So what does that mean?
By my take that meant that in 1959 we produced between 5% and 85% of the worlds green house gases and in 2009 we produced about 10% to 90% of the worlds total green house gases.

I dont know about you but a tolerance of 5% to 90% seems pretty wide and inconclusive to me.

Would you like your tax man to use a 5% to 90% applied variable on your income?
He might only charge you 5% but then again he might charge you 90% too. It just depends on what reference source he felt like using that day.
