Possible Questions Without Bias
The person giving the survey may want to consider these possible alternative questions.
Do you support government funding of studies on global warming?
What do you think about government funded research on global warming?
How do you feel the government is handling the global warming situation?
How do you think global warming should be addressed?
Although these questions are unbiased by definition, it is now more appropriate to use the phrase climate change rather than global warming. Global warming is, in and of itself, biased wording.
