I wish I was at the ocean…
This argument is very well constructed. He introduces his subject using questions about global warming and what we already know about it. He then goes directly into his topic and gives us a visual representation of his argument. The visual aspect gives us a better understanding of what he is talking about. If he would have just talked about it, it might have been harder to follow. Visual representation adds to the whole comprehension of the subject. Hearing it and seeing it at the same time helps immensely. Having the visual portion along with the explanation creates a very strong argument.
Also he addresses what others have addressed with a different spin on it. He compares his chart to buying a lottery ticket and how it is up to us which ticket we have to buy. He uses this to give us a personal connection with his subject. The speaker lets us know that we are also involved in what happens. The pathetic approach plays on the audience and creates a strong argument.
The only flaw that is present would be he didn’t have all of the possible aftermaths of whichever column or row we choose. He picked the main ones but there are others that could happen and he didn’t address them. Depression is huge but he needed to address other things that go along with spending money like that.
His conclusion was also very convincing. After giving his argument and backing it up with good information, he asks us to help him. Again he is appealing directly to us. Having direct audience interaction makes an argument stronger. He uses convincing diction to encourage us to aid him in his mission to inform as many as possible about what could happen. His whole argument wouldn’t work without the audience’s help.
