13. Convincing. We would like to know what you think of the Nature Science study, excerpts of which you just read. In your view, how convincing was the study on a scale of 0-10 with 0 meaning “completely unconvincing” to 10 meaning “completely convincing”?
Please indicate how strongly you disagree or agree with the following statements concerning the study. [Strongly disagree, moderately disagree, slightly disagree, slightly agree, moderately agree, strongly agree]
14. Biased. The scientists who did the study were biased. 15. Computers. Computer models like those relied on in the study are not a
reliable basis for predicting the impact of CO2 on the climate. 16. Moredata. More studies must be done before policymakers rely on the
findings of the Nature Science study.
