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

I think that Aarondeep Bains is right to say that the initially formulated question is too vague. We don't really know what it is measuring as it sounds like a statement that is neither positive or negative. I think Aaron's version could be a nice alternative. I would say that if we want to know it the person will feel personally concerned about climate change it should not be more than 30 years because after that they would probably care less or case only indirectly for their kids. However, I think that by adding the sentence("Climate change has had pronounced..." ) we are influencing too much the answer because we are actually saying: everyone says it has some effect, do you think it will affect you ? Which I think it's too biased in favor of the yes.

What about rephrasing it in order to have a scale (from 1 to 5 or something similar)? I always feel that people would never say no because it's too extreme, but they might say, "somehow".
