I'm shaking my head so hard right now you can blend paint colors in my mouth. Good grief. All this tells me is how stupid and gullible people who read skepticalscience.com really are. Let's begin with this lesson
Co2 is not a poison. Its a natural gas that is essential for human and plant life to exist.
Co2 represents 0.04% of the earth's atmosphere. Dry air is comprised of 78% nitrogen, 21% oxygen and the remaining 1% are trace gases - argon, carbon dioxide, methane, nitrous oxide, neon, helium.
Water vapour ranges from 0.1% to 4.2% of the atmosphere, depending upon the temperature. On it's own it accounts for 60% of the greenhouse effect.
96% of co2 is naturally produced by oceans and plants. 4% is human produced through the burning of fossil fuels, deforestation and other land use changes.
Greenhouse gases are comprised of water vapour 95%, co2 4%, 1% methane, nitrous oxide, ozone, CFC's.
To summarize co2 is a trace gas in the atmosphere 400 ppm or 0.04%. 96% of it is naturally produced. And it represents 4% of all greenhouse gases. Yet the AGW proponents target it as being the primary culprit of climate change. Take 4% of 4% what do you get. That's right. Nothing. Nil. Zilch. And how much have we contributed in $ to help combat this bogeyman? How many economies do we need to collapse? How many more Al Gore's are we going to line the pockets of? And most importantly how many people in the developing world need to starve because we won't let them industrialize using fossil fuels?
