In the video I labeled "no significant aspect can be controlled by a single variable" as the conclusion. An attentive 7Sager pointed out that it's actually the sub-conclusion. It's supported by an appeal to authority premise "any professional meteorologist will tell you that". The main conclusion is "I disagree."
Restructured, the Meteorologist's argument starts with an appeal to authority, supporting a general sub-conclusion, supporting a specific sub-conclusion.
