What are some arguments against global warming?

1. CO2 has never caused warming, it has only followed it
2. There have been zero record years of warming since 1998
3. The warming we have seen started over 6000 years ago
4. There has been only a 0.007% change in our atmosphere
5. Ice has been growing in the Antarctic at roughly the same rate as the 4% decrease in the Arctic
6. The current research is extremely incomplete
7. There have been 4 known cycles similar to present all with more warming then present
8. CO2 is not the primary greenhouse gas, water vapor is (80% is water vapor)
9. Man produces less then 7% of all CO2
10. Man produces less then .3% of all greenhouse gas
11. Many climate experts call the concept foolishness
12. The hockeystick graph ignored the warming of the middle ages and can not be reproduced.
13. Doc Hansen (creator of the idea) has been found doctoring numbers and sloppy work
14. From 1938 until 1979 science was pretty sure of global cooling
15. Most of the current warming occurred before 1938 (11 degrees)
16. 1850 is the start year used for most claims of warming because it was a extremely cool year
17. Only 0.2 degrees of warming has occurred if we use 1938 as a start point
18. Global Cooling has occurred if we use the 1400's as a start point

The most common is that we have not been studying the phenomenon for enough time to determine if it is just a natural fluctuation--i.e., a naturally occurring cycle of climate change.
