Alberta also has private liquor stores.
The issue isn't that there isn't a text book or a clear laymen description of the problem it comes when someone says: so prove to me that the churn of the lower atmosphere can carry these gasses to the upper atmosphere and the scientist starts talking about climate models which cannot predict any specific event with a high degree of accuracy but do tend to predict trends with great accuracy. To me this is like saying: what is the energy of a particle in a chamber at a defined pressure, temperature and density. The answer is very easy to give the average but essentially impossible to give the exact unless your model knows ALL of the inputs (i.e. every momentum vector and quantum state of every atom contain within the chamber).
To do nothing is to be nothing.
