Why are carbon dioxide (CO2) emissions, particularly the relatively small amount emitted by human activity, the sole focus of most climate change debates?
Even among the so-called ‘greenhouse gases’ (GHG), CO2 accounts for less that 4%, with water vapour being by far the most significant GHG
At 385 parts per million (ppm) by volume, CO2 levels are now, in a geologic sense, at their lowest in 600 million years
It leads me to believe that Al Gore and other politicians preaching over CO2 gas are actually blowing smoke. He is leading the general public to believe that humans are the man cause of global warming, when in fact humans have no impact at all!
Nobel Peace Prize or not, Al Gore believes in something that is not sciencetifically proven.
He needs to state that before he scares all of the cattle of the world, maybe he can also talk them into buying swamp land or jumping into hot lava!
What is your view on that subject, remember I’m not discussing pollution this is a global warming discussion. People love to change the subject to pollution.
My goal is to open everyone’s eyes
I think we are essentially living in virtual reality so it is increasingly important as you say to "question everything." Some people take this seriously thank goodness as I am often challenged with the question, "Why should we believe you any more than these other people?"
The answer is, "You shouldn't!" However,, check what I have said and confirm the evidence with as many different sources as you can find.

You sir are a liar and your post is a complete fraud.
Just the single fragment quoted above is incorrect in every way possible.
Currently we in 2008 are at 385 ppm. In 1950 we were at 310 ppm. In 1900 we were at 290 ppm. In 1850 285 ppm and in 1750 we were at 275 ppm. Thus in 2008 we have the highest CO2 concentration in the last 100 years. Furthermore, ice core samples indicate that in over 400 million years C02 has never exceeded 300 ppm by volume and at their lowest were below 200 ppm

I don't know where DavidJames gets his info from but it's way off. CO2 levels were much high in the past. Where do you think all the Carbon that is trapped in oil and coal came from. It came from a lot of plants that took the carbon out of the air and it got trapped in the plant matter. Add heat, pressure, and a few million years and you get oil. So all the carbon coming from all that oil and coal was once in the air. And with all that CO2 in the air the earth never had unstoppable global warming. AL Gore lies.
Now i have a serious concern about reversing the damage to our world that has been done so far. Our eco system has had hundereds of years to adapt,change it's own behavior, and try to overcome what we as humans have done. My question is, if we try to undo the damage so quickly, might our eco system not be able to handle or have time to adapt to the new clean changes we will be making? If you think about it,the time that the eco system had to adapt to the severe climate change and particals in the atmosphere was great, and we will reverse it in about 10% of the time. I believe that life will go into a catastrophic collapse; photosyntheses,marine life, and all that is still holding on to the way the earth is right now. It is possible that it wont, but the dramatic change could through our enviroment for a loop. Please give feedback and i would very much appreciate a scientist explain to m how this could not happen. THANKS
the problem with testing for global warming is that there is way to many variables to account for. our atmosphere is only .1% CO2, there are plenty of other green house gasses. for example, methane. termites and cows release more methane than cars do and yet we dont calculate this variable. scientists are trying to PROVE something, not DISPROVE something, which the scientific law states. pretty much they are testing a control and basing all decisions off of that. i think that until somebody accounts for all the other variables of the universe, we can blame humans and CO2.
Carbon dioxide levels were much higher in the past - but that was at a time when there was no life on earth. It took carboniferous plants many millions of years to remove the carbon dioxide and replace it with oxygen, which enabled animals to be able to live on the land too.
However, in the lifespan of the human beings (5 million years or so), we have never seen carbon dioxide levels as high as they are now.

Hi Question-everything, nice aka nickname. I just want to tell few thing. Since the beginning of time, there were no trucks, as there is now all over the globe. Trucks use gasoline in order to run/start. We suck the gas, from underground, as it's the only place we can find as of right now, that is readily available. By doing this, I mean sucking the oil from under ground, we are doing two things. One, we are depleting the oil, which is insulating us from the elements that comes out of volcano, and at the same time, we are redistributing it after changing the state from gas to particles which fly off and give us this what we call pollution, which is causing everyone to misunderstand what is really happening with this Global Climate Change. That is why there are a number of car companies that would probably be hybrid, or trying to get away from this gas guzzling beast, same thing with powerplants that power your house.

this is what I meant when I said since the beginning of time, until the "Industrial Revolution Era". We are rearranging enormous amounts of weights around. If you're a smoker, or have been inside a same room with a smoker, you'll notice that the smoke that is being exhaled tend to hang around the same height layer, and it depends on number of people smoking, I mean this intensity of haze. This is what exactly is happening to this planet. We are exhaling too much pollution from our cars, power plants, whatever that excretes pollution.

The genuine cause of global warming is our thoughtless attitude to nature. I do believe that somehow human CO2 has a little impact to global warming. Not the human CO2 is the cause but human himself is the cause.
What happening is that we are depleting the crude oil from underground. Then, in turn, the crust is being warmed up, and in turn the atmosphere is being warmed up by the warmed crust. Then the water that was on the crust is being evaporated, turning into a cloud, shading the ground below it, causing it to cool the ambient air, causing us to think that there is no global warming, when actually it is warming up for the past decades. If there were no global warming, then all these few past years, we should have seen sunny days during spring and summer. But all we see is cloudy, overcast is the norm for the next few years I think. Then it will suddenly get warmer, if we keep on depleting the crude oil from underground. And when we change the balance, by sucking the crude oil, we create "Chandler's wobble" and adding more wobbles to this wobble, creating hot/cold sensations because of this size of the earth, confusing us.
Now try to grasp what I am going to add. It is warming up no doubt, but this wobbling, is the result of this rearranging enormous amounts of weights around, we think is miniscule. We clear the forests so we can wipe our buts, and because the earth is overpopulating so fast, the resources which gives us the products, cannot keep up, can't grow fast enough, can't support too many people, and that's why we're creating a barren land, but the real barrenlands will flourish for about a decade or less, then get real hot too.

Human made CO2 is actually less than 3% of the total value of CO2 amongst the greenhouse gases. CO2 is less than 4% of all greenhouse gases, and all greenhouse gases makes up about 2% of the total atmosphere. This value is unimaginably small, IN ADDITION to the 400 year lag in the Antarctic ice showing CO2 follows temperature and not the other way around. However, activity in the sun corresponds to the temperature of the earth very accuratly.

I guess you still do not conceive what human beings are capable of...Not only does this oil extracting is one of consolidation of causes, but look at the very smart humans. We depleted forests, so we can expand and develop to meet our needs, which cuts the sustainability of resources, no matter what they are...traded for space....so you can sleep under a comfortable warm dry bed....This kinds of makes a toppling rotation of the earth's axis, hence the term "Chandler's Wobble"....All of the events' humans are causing, results in this disasterous rotation, adding a baby wobble to chandler's wobble, exposing different regions to sunrays, because in one area is land and another a water, exposing the different terrain will have a different result, a hurricane or a sunshine. Combined human caused happenings....leaving everything in the dust....desert....dry....hot......get it?
I guess in a way...we are SAYING THE SAME THING! WOW!

While you are correct in saying that CO2 levels are higher than they have ever been with humans around (as far as I know), there have been much higher levels with plenty of life around. Life has existed on Earth for over 2 billion years, and yet the atmospheric carbon dioxide concentration just 500 million years ago was at least over 2000 ppm by volume, and likely around 5000 ppm. Animal life existed at that point in time. Animal life will continue to exist even if humans wipe themselves out through climate change. The overall biomass will adapt.
