Brother, your essay is fine as far as the topic "global warming" is concerned but you have mentioned more irrelevant material than relevant material. You should have focused on the topic of essay more than on the matter which was not required

Moreover, I think that your outline is too lengthy. I may be wrong, but I don't think that v would have been able to write as much as you have mentioned in your outline due to time constraints. Can you tell me how many pages did u write on this outline ?
