Q4. Do you think climate change will have an affect on Canada/Vancouver in...

My understanding of the question was that it is gauging people's actual belief in climate change- Do they think it currently has an impact or will have an impact. This question does leave out people who think climate change is a hoax and will never have an impact because it is untrue- yes they do exist! Additionally, it gauges their understanding as to the progression of climate change- will the ramifications of their actions be felt during their life time or will the impacts only appear after they are gone?

Reading it from a different perspective that comments have brought up I understand how it could also be viewed as a question of how environmental practices impact a specific region such as Canada or Vancouver since that is the region mentioned. If that was the intention of the questions it definitely needs to be re-worded.
