My view of this survey is that it is much too limiting in the questions they are asking regarding the findings in the peer reviewed literature. It appears they are writing their questions to reinforce a preconceived perspective, rather than complete an actual survey of the diversity of viewpoints in climate system science and the role of humans in its alteration.
Rather than asking the broader question of the role of humans in the climate system, the survey highlights the “endoresement” that
the level of endorsement for the proposition that human activity (i.e., anthropogenic greenhouse gases) is causing global warming (e.g., the increase in temperature).
This is hardly a survey that is going to broaden out the assessment of the current perspective of the peer review literature on climate science. I hope they take my recommendations and expand their survey questions.
