While the COVID-19 pandemic appeared to temper concerns about climate change in 2020, the issue has risen to prominence again in 2021. The majority of Australians (60%) say ‘global warming is a serious and pressing problem…we should begin taking steps now, even if this involves significant costs’. This represents a reversal of the dip in 2020 during the early days of the pandemic, but remains eight points below the high watermark of concern in 2006. A third of Australians (30%) say the problem of global warming should be addressed, but its effects will be gradual, so we can deal with the problem gradually by taking steps that are low in cost. Only 9% of Australians — one of the lowest results of the past decade — say that until we are sure that global warming is really a problem, we should not take any steps that would have economic costs. As in recent years, there is a significant gap between younger and older Australians’ concerns about global warming. Despite a slight narrowing between the generations, the margin is still noteworthy, with three-quarters (76%) of Australians aged 18–29 saying global warming is a serious and pressing problem, compared with 50% of those over 60. Concern about global warming appears to be narrowing slightly between the urban and rural populations, with just a 7-point gap between the 63% of Australians living in cities saying that global warming is a serious and pressing problem, and the 56% of the regional and remote population.
