Global Climate Change Argument
Fallon Mullen

The Global Climate Change argument video that we viewed is highly complex and interesting and highlights the use of logic to decipher a conclusion from an argument that is heated and reoccurring. As I watched the video I felt that the argument fit the form of Modus Tollens and Modus Ponens.

Modus Ponens:
If we act, then the world won’t end
We acted
So, the world won’t end.

Now maybe that is true and I understand he is depicting the worst but I feel it suits the slippery slope fallacy. Another fallacy I believe was committed is appeal to ignorance, which is a fallacy that lacks opposing evidence to the conclusion being argued. Now, I agree that his conclusion is inescapable but Greg Craven says that column A is “the only responsible choice and the only defensible choice” which I feel could be an appeal to ignorance lacking contrary opinion and portraying his conclusion as the end all be all decision. The third fallacy I felt was present was post hoc ergo propter hoc, which is a logical fallacy that states if a certain event has happened that followed another event they must be associated. Greg Craven speaks of the scenario in which we act but the Global Climate Change crisis winds up being false, he says, “Lets say we wind up with massive layoffs caused by Draconian regulation which sparks a recession which spirals into a global depression.” I feel this may include post hoc ergo propter hoc because it has the connotation that spending the money with no real global climate change crisis would certainly result in economic
