I understand perfectly the point you are trying to make, but in order to make this point you have to examine more thoroughly what the scientists say about climate change. They say that the gases we emit destroys some layers protecting the earth like the ozone layer, you are supposed to examine whether this is true, because if it is true then it means the actions of man are destroying some of the Earth's natural protection and thus the protection from the sun's radiation is getting weaker which would result in more heat. You understand what I'm saying?

Also, what you said about some high polluting areas in Brazil not being the hottest is not really a good point because scientists say that winds carry the gasses we emit and might blow them further away from where they were emitted.
