Roy Morgan Research has asked its global warming question again, and found that the proportion of the electorate Australians believing that climate change concerns are exaggerated is up again, from 27% to 30%. Disapproval of the ETS is up from 24% to 31%.

The Pollytics blog analysis of these results shows that it seems to be largely driven by partisan effects, with Labor voters becoming less likely to believe that concerns are exaggerated and Coalition voters more likely to believe that concerns are exaggerated (surprisingly, Green voters are also showing increased scepticism; if this is real it is perhaps a reminder that about a third of Green voters appear to be low-ideology, not-rusted-on, supporters).

Roy Morgan also asked an open question about why voters disapproved of the legislation. I’ve tried to organise them into categories, and find that those giving sceptical reasons are 9% of the sample (or just under a third of ETS opponents), those thinking the ETS is futile are 8.5% of the sample, those thinking it costs to much are 8% of the sample, those offering tactical reasons are 6.5% of the sample, those offering cynical reasons (eg distribution of credits is unfair) are 1.5% of the sample, as are those saying the public doesn’t know enough.

So there are several broad reasons for opposing the ETS, with none dominant.
