I am not sure that he convinced very many people about the climate change with his movie. I think that most people who watched the movie probably already were aware of the situation. I do know though that it had a huge impact on my teenage daughter and her awareness after seeing it.
Oh, sorry... Not me, at least. I already read a lot of stuff about climate change and stuff and so I didn't bother to go and see the film. I already believed that climate change was going on and that it was caused by people. So for me, it's not that he wasn't persuasive, it's just that I didn't need him to tell me about the problem.
It would be very difficult to answer this question without taking very detailed polls. We can have some idea as to what people think on this issue, but we cannot know if Al Gore influenced their beliefs or not unless we ask them. This has not been done to my knowledge.
We do know that there is a great deal of skepticism about climate change in America today. Many people do not believe that climate change is happening. Some believe it is happening but do not believe it is caused by human beings. So in that sense, Gore has not managed to get his message across. There are still very many people who do not believe what he is saying.
There are probably people who he did convince, but we do not having polling to show how many people were actually affected by his arguments or his film.
Sorry I meant like people as in like if you watched the movie did he effect your opinion
