I believe that by the middle of next decade people denying significant human agency in causing climate change will constitute a crank fringe and will basically be ignored.
The Climate of the Nation 2018 report, now produced by The Australia Institute (pdf here), found that more Australians accept the reality of climate change than at almost any time since Climate of the Nation began in 2007.

Three quarters (76%, up from 71% 2017) of Australians accept that climate change is occurring, 11% do not think that climate change is occurring and 13% are unsure.
Acceptance of climate change closely follows voting intentions, but interestingly while One Nation (22%) and Nationals (15%) voters are the most likely to say they do not think that climate change is occurring, this declined significantly for both groups since 2017.
The effects of heat are the driving concern about the impact of climate change, and people were most concerned about more droughts and flooding affecting crop production and food supply (78%), destruction of the Great Barrier Reef (77%) and more bushfires (76%).
