You sound very confident about that. Maybe you should enlighten the scientific community of your discovery of the cause global warming. They would be very interested.
The point is we just don't know and it would be ignorant not to study all possibilities, especially when there may not be just one reason.
Heres an example... our magnetic field is currently weakening and the suns energy output recently hit its max in its life time... hmmmmmm.... now consider the expansion of industry, deforestation, increases in livestock, depletion of ozone and even the cyclical thing JofM mentioned...
I suggest to stop arguing over this. Its just too complicated for people with no formal education on the matter to waste their lives on. Leave it to the professionals.
