Dear David‹Interesting results, but I must say that I think your first question is phrased in an unfortunate way. Scientists are trained not to ³believe² in one answer or another, but to consider the evidence (of all types) and to draw conclusions from the evidence. We (scientists) when asked if we believe in human-induced climate change should be saying no, that our findings are based on very convincing evidence.
I also thought question 4 could have been better phrased‹it is doubtful that any scientist would say we would ever ³fully understand² any complex subject, much less how the global Earth system works. The question comes back to whether understanding is adequate, and in every decision that is the issue‹comparative risk. And comparative risk is how at least some of the questions on geoengineering would have been better phrased. The choice is not between today¹s climate and today¹s climate with climate engineering‹it is between a rapidly warming and changing climate without climate engineering, or a possibly more stabilized climate with climate engineering. And with respect to our level of understanding, the current level of understanding is, for most of us, enough to justify calls to change the entire global energy system. In that most climate engineering approaches imitate natural processes that are already largely encompassed in our overall understanding, it seems to me that question 5 about harmful unforeseen consequences needs to also be made relative to the likelihood for surprises and nonlinearities, etc. from not pursuing climate engineering. Certainly, there is much that needs to be learned, but it seems to me a nor nuanced phrasing of the questions is how the issue would most appropriately be posed to both the scientific community and the public. Inaction over past decades has gotten the world into quite a pickle, and I think this needs to be made clear in all the questions that are asked.
