Perhaps they also want to signal a sentiment similar to that of Freeman Dyson:
I believe global warming is grossly exaggerated as a problem. It’s a real problem, but it’s nothing like as serious as people are led to believe. The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm. It distracts people’s attention from much more serious problems.
“Significant” is just too vague. Everyone who gave an answer was answering a different question, depending on how they interpreted “significant”.
The survey question itself indicates a primary problem with the discussion of global warming—a conflation of temperature rise and societal cost of temperature rise. First, ask a meaningful question about temperature increase. Then, ask questions about societal cost given different levels of temperature increase.
