"I believe that the Earth is getting warmer, however I do not find sufficient evidence to show that this will be a net bad thing for humanity. Further I do not believe that the proposed measures are the wisest course of action, and we should be investigating alternatives such as geoengineering. In any case we should not act yet, as we do not have a solid enough model of what will happen and the net impact on humanity."

Goes double if the people who are doing the vote try and make it a black and white issue. If they try to make it an issue where you either have to support everything they say, or you are an evil denier of all science, it'll be much easier for people to abstain and have a good argument.
