6 Although we are in the third decade of climate science communication as a discipline, and there is 7 overwhelming scientific consensus and physical evidence for climate change, the general public continues to 8 wrestle with climate change policy and advocacy. Early adolescence (12 to 13 years old) is a critical but 9 under-researched demographic for the formation of attitudes related to climate change. This paper presents 10 opinions on the worry, cause, and imminence of climate change that were collected from n=463 1 st year 11 secondary school students (12-13 years old) in public secondary schools in inner-urban centres in Austria 12 and Australia. Overall, 86.83% of eligible respondents agreed that climate change was probably or 13 definitely something we should worry about, 80.33% agreed that climate change was probably or definitely 14 caused by humans, and 83.17% agreed that climate change was probably or definitely something that was 15 happening now. The respondents' opinions were also compared to their respective adult population, with 16 Australian 12-13 year olds showing strong positive climate-friendly attitudes, both in comparison to their 17 adult population, and to their Austrian peers. In addition, although the opinions of Austrian 12-13 year olds 18 were quite high, they did not reflect the higher climate-friendly opinions of their adult community. Our 19 results suggest that socio-cultural worldview or socio-cultural cognition theory may not have the influence 20 on this age group as it does on the respective adult population -and, if they are affected, there are attitudes 21 or factors in this age group which resist the opinion-influence from their mature community. These findings 22 are significant as early adolescents may be pivotal in the climate science communication arena and 23 investigating their opinions with regard to climate change may offer an unexplored and under-utilised target 24 for future communication efforts and climate literacy programmes. 25 2 46 knowledge, 6) the wicked nature of climate change and, lastly, 7) a lack of certainty 19,20 with regard to the 47 scientific consensus or trust in the findings from the scientific community.48 Navigating 1) worldview is, perhaps, the most pernicious challenge to overcome as it involves the 49 individual's idiosyncratic belief system and their attachment to social, political and cultural networks 11,21 . 50 Worldview is a factor known to not only prevent, but to inoculate an individual from re-assessing existing 51 opinions or idiosyncratic belief systems 22,23 . Attempts to promote re-assessment of beliefs can lead to an 52 individual entrenching their opinion more firmly and undermining further communication efforts 2 .53 In addition to worldview, a great deal of 2) misinformation is generated both when lay-people attempt to 54 rationalise and organise the information they are given or search for 24 , as well as misinformation that is 55 created by groups or industries that are threatened by a well-informed general public 10,[2...
