Amen brother. Every time I have a discussion with one of the dimwitted global warming folks, I ask them if they know what % of the earth's atmosphere is CO2. Half don't know and the other half have given answers ranging from 5 to 21%. Then, I play the what-if game. What if it's 1%, do you think mankind can make a difference by "reducing your carbon footprint"? What if its .4%, would reducing the carbon footprint of humans have any impact?
Then when I ask what-if CO2 were only four one-hundredths of one percent, would reducing consumption of oil make any damn difference?
If they still seem interested, I hit them with 95% of the CO2 is in the form of water vapor. That usually blows their mind.
Now just a second.
How do you get CO2 out of H2O?
