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.
