Abstract: The aim of the research is the examination of the factors influencing the public perception of climate change and its impact on natural disasters. This paper presents the results of quantitative research regarding testing the central hypothesis where education is the predicting variable of public perception of climate change and its impact on natural disasters. A multivariate regression analysis was used, identifying the extent of the total scores of the main dependent variables (perception of vulnerability to climate change, perception of the climate change impact on natural disasters, knowledge and fear scores) were associated with five demographic and socio-economic variables: gender, age, marital status, education level, and employment status. A series of 208 face-to-face interviews were conducted during the beginning of 2020 on the central squares in the selected cities in Serbia, Belgrade (76.92%) and Sremska Mitrovica (23.08%). The results showed that education level was the most effective predictor of the mentioned research variables. Besides, employment status has been found to affect perceptions of vulnerability, while age affects the perceptions of climate change. Based on the obtained results, policies and strategies to improve people’s awareness of climate change must take into account a comprehensive understanding of behavioral dispositions.
Keywords: climate change; natural disaster; public; perception.
Introduction
Public perception of climate change and its impact on the distribution of the frequency and severity of the consequences of natural disasters greatly influence the implementation of climate policies, the design of educational programs, and the undertaking of preventive measures (Allan et al., 2020; Cuthbertson, Rodriguez-Llanes, Robertson, & Archer, 2019; Seara, Pollnac, & Jakubowski, 2020; Ruiz, Faria, & Neumann, 2020). The majority of the population views climate change as an area that is important for humanity, but when it comes to their daily lives, the issue of climate change is something that is far and less important (Capstick et al., 2015). This perception of the problem of climate change changes after a personal confrontation with the consequences of climate change in the form of extreme weather conditions, which increases the desire to participate in solving the problem (Capstick et al., 2015). According to Adamo, Al-Ansari, and Sissakian (2020), climate change as a phenomenon is nothing new for scientists because geological evidence shows that the climate

system has had periods of stability and variability throughout the planet’s history. Global climatic conditions in the last 10 millennia have created favorable and optimal conditions for the development and expansion of both humans and flora and fauna (Arora et al., 2018). Climate change is a phenomenon that is an integral part of the functioning of the planet, caused by natural processes and anthropogenic influences, i.e., greenhouse gas emissions, which worsen the negative effects of climate change on the functioning of human communities (AghaKouchak et al., 2020; Hoogendoorn, Sütterlin, & Siegrist, 2020; Hussain et al., 2020). Intense and devastating natural disasters, caused by climate changes, weaken the resilience of communities (Cvetković, Nikolić, Nenadić, Öcal, & Zečević, 2020; Cvetković, Öcal, & Ivanov, 2019; Cvetković et al., 2019), due to the lack of time and resources for recovery (O’Brien, O’Keefe, Rose, & Wisner, 2006).
The negative effects of natural disasters on communities are evident, and an increase in their frequency and intensity is noticeable (Cvetković & Dragicević, 2014; Öcal, 2019; Semenza et al., 2008; Shi, Visschers, & Siegrist, 2015; Yu, Wang, Zhang, Wang, & Wei, 2013). Floods, severe storms, earthquakes, and droughts result in lower mortality rates than socio-political phenomena such as armed conflicts, but still occur more frequently and affect a higher percentage of the population (Fujita & Shaw, 2019; Hunter, 2005). It is estimated that between one-fifth and one-quarter of the world’s population was threatened by a natural disaster during the 1970s and 1980s (Hunter, 2005). In the last few decades, there have been serious debates and discussions, both at the local and international level, about the existence of climate change impact on the occurrence and destructive effect of increasingly present natural disasters (Banholzer, Kossin, & Donner, 2014; Bouwer, 2011; Davies, Oswald, & Mitchell, 2009; Kumiko & Shaw, 2019; Mano, Kirshcenbaum, & Rapaport, 2019; O’Brien et al., 2006). Global warming has a direct impact on the increase in the amount and change of the established precipitation patterns (Chakma, Hossain, Islam, Hasnat, & Kabir, 2021; Kilpeläinen, Kellomäki, Strandman, & Venäläinen 2010). The increased temperature causes greater evaporation and faster drying of the soil, which increases the intensity and duration of drought. With each degree of temperature increase, the capacity of water absorption in the air increases by 7%, as well as the amount of water vapor in the atmosphere (Emanuel, 2017; Hatfield & Dold, 2019). Higher precipitation means a higher percentage of rain instead of snowfall, earlier snow melting, then the risk of floods in early spring increases, as well as droughts during the summer period, especially in the continental parts (Trenberth, Cheng, Jacobs, Zhang, & Fasullo, 2018). Natural disasters in Sri Lanka have intensified and become more frequent, as a result of anthropogenic activities and climate change (Ratnayake & Herath, 2005). A study of the impact of climate change on the increase in fire risk at 17 locations in the Southeast Australia region, showed that the number of days when the risk of fire is higher, will increase by 4–25% by 2020 (Lucas, Hennessy, Mills, & Bathols, 2007). The rise in global temperature, caused by anthropogenic impact and greenhouse gas emissions, is exacerbating the situation in many regions, increasing the potential for droughts, or their intensification (Cook, Smerdon, Seager, & Coats, 2014). Gleick (2014) found that between 1988 and 2006 there was increased evaporation in the eastern Mediterranean, indicating an evident increase in the average sea temperature. Adding to the rise in temperature, all the factors together provoke the rising of sea levels, more frequent sandstorms, and the disappearance of groundwater.
Climate change is a reality, and this is evidenced by many studies that have confirmed temperature changes and changes in precipitation patterns (Burić, Ducić, & Mihajlović, 2018; Mahmoudi, Mohammadi, & Daneshmand, 2019; Ruml et al., 2017). In Serbia, it was determined that the frequency of precipitation is at the intensity above the extreme occurrence level (1961–2015) and the frequency of precipitation is at or above the absolute daily maximum during the reference
period (1961–1990) (Anđelković et al., 2018). Besides that, Malinović-Milićević et al. (2018) determined that the climate of the northern and central parts of Vojvodina is getting wetter in terms of the precipitation magnitude and frequency, reflecting the characteristics of the central European regime. Besides that, it was found that a determined increase in air temperature and the reduction of precipitation in the examined period has a significant influence on the possibility of fire occurrence (Živanović, Ivanović, Nikolić, Đokić, & Tošić, 2020). Having in mind the importance of disaster risk perception for the adoption of the appropriate policies and programs for climate change reduction and its impact on natural disasters, the aim of this paper is to investigate the public perception of climate change and its impact on natural disasters through the following dimensions: (a) perception of vulnerability to climate change; (b) perception of the climate change impact on natural disasters; (c) assessment of knowledge about climate change, and (d) perception of fear of climate change and natural disasters.
Literature review
Many papers in the literature examine citizens’ perceptions of climate change (Semenza et al., 2008; Shi, Visschers, & Siegrist, 2015; Xie, Huang, Lin, & Chen, 2020; Yu et al., 2013) and its impact on increasing disaster risk (Anderson et al., 2018; Reser, Bradley, Glendon, Ellul, & Callaghan, 2012a). In some papers, the influence of education, awareness, and knowledge (Drummond & Fischhoff, 2017; Leiserowitz, 2007), print and electronic media (Kahan et al., 2012; O’Neill, Williams, Kurz, Wiersma, & Boykoff, 2015), gender and age (Shi, Visschers, Siegrist, & Arvai, 2016; Zaval, Keenan, Johnson, & Weber, 2014), previous experiences (Moyano, Paniagua, & Lafuente, 2009), perception of individual health (Hamilton, Hartter, Lemcke-Stampone, Moore, & Safford, 2015; Scruggs & Benegal, 2012), etc. are examined. Cvetković, Tomašević, and Milašinović (2019) determined that educational institutions, after the electronic media, are the most common way of informing the citizens of Belgrade about the security risks of climate change. Chou (2013) determined that the poor public confidence in the government’s ability to fight climate change and the public has called for more risk coordination, transparency, and engagement in climate change policy-making. Lewis (2016) found that the measured temperature patterns are incompatible with the subjective viewpoint interpretation of extremes as objects only of climatic variability. Ruiz et al. (2020) found that attitudes are directly affected by the exchange of values and beliefs within the culture and the direct impact of climate change. They also found that implicit factors are related to the degree of community growth and the distribution of knowledge on climate change. Echavarren, Balžekienė, and Telešienė (2019) came to know that the variation of the concern about climate change is not clarified by political governmental circumstances, and education and political preference are critical mediators. Lewis (2016) discovered that the properties of temperature recorded are incompatible with the private perception-based understanding of extremes as manifestations of natural climate variability alone.
A survey on risk perception, understandings, and responses to climate change (Reser, Bradley, Glendon, Ellul, & Callaghan, 2012b) in Australia, found that 74% of the respondents believe that the world’s climate is changing, 50% already feel the effects of climate change, and more than half of them express their personal and immediate concern for their undoubted influence. In the same research, it was found that more than 76% of the respondents believe that it is necessary to take certain measures as soon as possible to mitigate the effects of climate change. Capstick, Pidgeon, and Whitehead (2013) show that most citizens in Wales (88%) believe that climate change is happening. Also, they point out that a little more than half of the respondents (52%) state that the
cause of climate change is in the equal relationship between human activities and natural processes, more than a third of the respondents (35%) believe that change is solely due to human activities, while the least number of respondents (11%) think that the causes of climate change are exclusively certain natural processes. According to them, with concerns about climate change, more than a third (36%) of the respondents are very concerned, and a slightly higher percentage (48%) think they are quite concerned, while a few of them (7%) are not concerned at all. In another study, in the United Kingdom, Capstick et al. (2015) found that more than half (68%) of the respondents are very concerned about climate change, while a very high number of the respondents (88%) believe that climate is changing. Also, for the causes of climate change, less than half (48%) of the surveyed population believe that natural processes and human activities are equally responsible for them, and more than a third (37%) believe that human activities cause climate change. Only 12% believe that nature itself regulates climate change. More than half of those surveyed (55%) think that the effects of climate change are already being felt in the UK, while just over a fifth (23%) of those surveyed think the effects will be felt in 10–25 years.
Methodology
The subject of the research is a scientific explanation of the manner of influence of certain predictors (gender, age, marital status, education, and employment status) on the public perception of climate change and its impact on natural disasters (Figure 1). A series of 208 face-to-face interviews were conducted during the beginning of 2020 on the central squares in the selected cities in Serbia, Belgrade (160 participants, i.e. 76.92%) and Sremska Mitrovica (48 participants, i.e. 23.08%). Beginning with the population of all the people living in the city’s area of Belgrade and Sremska Mitrovica, every fourth passer-by was interviewed near the central square of the city. In situations where it was known that the touch passer-by did not reside in the city’s territory of Belgrade, he/she was not included in the survey and the next fourth passer-by was chosen in the manner referred to above.
Figure 1. Research design.
The structured questionnaire was developed using close-ended and five-point Likert scale questions (1 = strongly disagree to 5 = strongly agree). The first part of the questionnaire contained the socio- economic and demographic characteristics of the respondents and the sections in the second part included issue questions related to (a) perception of vulnerability to climate change; (b) perception of the climate change impact on natural disaster; (c) assessment of knowledge about climate change; (d) perception of fear of climate change and natural disasters. Several published survey approaches were consulted (Capstick et al., 2015; Cook et al., 2014; Hamilton et al., 2015; Scruggs & Benegal, 2012; Semenza et al., 2008; Shi et al., 2015; Yu et al., 2013) and adapted to the conditions of the Serbian socio-economic status. In Belgrade (Central Serbia), a pilot pre-test of the questionnaire was performed in March 2020 with 25 people to test the comprehensibility and efficiency of the questionnaire. Our quantitative analysis was compatible with the Helsinki Declaration (Tyebkhan, 2003) defining the standards for socio-medical research concerning human subjects.
Socio-economic and demographic characteristics of the respondents
Of the total of 208 participants, 48.1% were women and 51.9% were men (women 51.3% and men 48.7% of the total country population—Statistical Office of the Republic of Serbia, 2020). The mean age of the participants was 34 years of age and perhaps the most represented group was 30–50 years of age (47.6%) while the smallest group was of the participants aged 50+ (19.2%) (average population age 42.6 years—Statistical
Office of the Republic of Serbia, 2020) (men 41.2 and women 43.9). It emerges from the study that the largest number (43.7%) finished university studies and only a small number finished primary school (5.3%) (secondary school: 26%, high school: 14.4%, undergraduate: 7.69%, and graduate: 36.01%). In the household sample, individuals in a relationship account for 33.7%, the widows/widowers for 3.84%, the divorced for 8.66%, and the married people rate for 38%. The respondents selected also represented the different status of jobs, with 75.5% employed. In comparison, the largest number (60.1%) of the participants had children (Table 1).
In this study, descriptive statistics were calculated for the basic socio-economic and demographic characteristics of the participants. T-test (Kim, 2015), one-way

ANOVA (Heiberger & Neuwirth, 2009), and multivariate linear regression (Tabachnick, Fidell, & Ullman, 2007; Yuan, Ekici, Lu, & Monteiro, 2007) were used to examine the relationship between the predictors and public perception of climate change and its impact on natural disasters. Bearing in mind that the preliminary analysis of the homogeneity of variance (Test of Homogeneity of Variances) have shown that there is a violation of the assumption of homogenous variance, used the results of the two tests—Welsh and Brown-Forsythe, which are resistant to the violation of the assumption. All the tests were two-tailed, with a significance level of p < .05. Statistical analysis was performed using IBM SPSS Statistics (Version 26). The internal consistency of Likert scales for Perception of Vulnerability Subscale (six items) is good with a Cronbach’s alpha of .85, for Perception of the climate change impact on natural disasters Subscale (five items) .84, Assessment of Knowledge Subscale (four items) .82, and Perception of Fear Subscale (five items) .85. To examine the factors associated with the overall scale, we performed regression analyses, with the four dependent variables (Table 2). We tested the central hypothesis where education is the predicting variable of public perception of climate change and its impact on natural disasters. A multivariate regression analysis was used, identifying the extent to total scores of the main dependent variables (perception of vulnerability to climate change, perception of the climate change impact to natural disasters, knowledge and fear scores) were associated with five demographic and socio-economic variables: gender, age, marital status, education level, and employment status. Previous analyses checked on the residual scattering diagram (Tabachnick et al., 2007), showed that the assumptions of normality (Normal Probability Plot P-P and Scatterplot), linearity, multicollinearity (r = .8), and homogeneity of variance had not been violated.
Results
Starting from the abovementioned methodological framework and research design, the results were divided into two categories:
- The predictors of perception of vulnerability to climate change, perception of the climate change impact to natural disasters, assessment of knowledge and perception of fear scores related to the public perception of climate change and its impact on natural disasters;
- Results of descriptive statistics and the relations between the variables and perception of vulnerability to climate change, perception of the climate change impact to natural disaster, assessment of knowledge and perception of fear scores related to the public perception of climate change and its impact on natural disasters.
The predictors of public perception of climate change
The multivariate regression analysis showed that education level was the most effective predictor of perception of vulnerability to climate change. Further analysis showed that the most important predictor for vulnerability is education level (β = .503), and it explains a 21.3% variance in the score of perception of vulnerability, followed by the employment status (β = .134, 1.1%). The remaining variables did not have significant effects on the perception of vulnerability. This model (R2 = .349, Adj. R2 = .333, F = 21.68, t = 7.63, p = .000) with all the mentioned independent variables explains the 33.3% variance of perception of vulnerability to climate change. Also, the results of the multivariate regressions of perception climate change impact on natural disasters showed that the most important predictor is education level (β = .577), and it explains a 28.9% variance in perception, followed by age (β = –.123, 1%). The remaining variables did not have significant effects
on the perception of the impact of climate change on natural disasters. This model (R2 = .416, Adj. R2 = .401, F = 28.73, t = 10.73, p = .000) with all the mentioned independent variables explains the 40.1% variance of perception of vulnerability to climate change (Table 2 and Figure 2).

On the other side, the results of the multivariate regressions of assessment of knowledge about climate change showed that the most important predictor is education level (β = .617) and it explains 31.36% variance in the assessment of knowledge. The remaining variables did not have significant effects on the assessment of knowledge on climate change. This model (R2 = .406, Adj. R2 = .391, F = 27.58, t = 10.33, p = .000) with all the mentioned independent variables explains the 40.6% variance of assessment of knowledge on climate change (Table 3 and Figure 2). Concerning to perception of fear of climate change, analyses showed that the most important predictor is education level (β = .565) and it explains 26.01% variance in knowledge. The remaining variables did not have significant effects on the assessment of knowledge about climate change. This model (R2 = .378, Adj. R2 = .363, F = 24.56, t = 5.95, p = .000) with all the mentioned independent variables explains the 36.3% variance of climate change fear (Table 3 and Figure 2).
Results of descriptive statistics and the relations between the variables and public perception of climate change
The results of the research show that the largest number of the respondents (56.7%) points out that, to a certain extent, they know about climate change, observed on a scale from 1 (absolutely know) to 4 (absolutely don’t know). Only 1.3% of the respondents point out that they know absolutely nothing about climate change, while 13.5% believe that they are familiar with such a phenomenon. Over 91.8% of respondents believe that the climate is changing globally, while 14% of respondents believe that the issue of climate change is not important to them at all on a personal level. On the other hand, 36.1% of the respondents believe that the issue of climate change is important in the perspective of everyday life. To a question related to concerns about the potential effects of climate change that they could have on them, most respondents believe they are partially concerned (31.7%), while 13.9% are not concerned at all. With the perceptions of the impact of climate change on society, the results are slightly different and 25% are not concerned at all.
Regarding the sources of information they trust the most when reporting on climate change, 51.9% of the respondents opted for scientists, 39.9% for the media, while 7.7% of the respondents said they trusted the authorities the most. When it comes to the perception of the causes that lead to climate change, the highest (46.6%) opinion is that the roots are in human activities, while 6.3% of respondents believe that these are natural processes, while 4% believe that these are mutual interactions of the mentioned factors. When asked whether climate change will cause a more serious problem in Serbia if certain proactive measures are not taken shortly, 51.9% have a positive attitude on this issue, while a very small number of 6.3% of the respondents believe that not taking such measures will not harm. On the other hand, 62.5% of the respondents believe that the impact of climate change is already being felt in Serbia, while 9.6% think that it will happen in the next 25 years, and 2.4% in the next 50, and 1.4% point out that this will happen in the next 100 years. When asked to assess the level of vulnerability of the region to climate change, 8.2% of the respondents point out that it is not endangered, while 47.6% claim that it is partly endangered, and 13.9% believe that it is endangered. About the perception of weather change due to climate change, 36.5% of the respondents point out that there is more frequent heavy rainfall, 30.3% that the temperature has risen, 18.3% that winters are warmer, 4.8% that summers are warmer, 1.9% say that the weather is extremely unstable, and 0.5% of the respondents point out that the winters are colder and the air is more polluted.
Bearing in mind that the increase in the average temperature is an integral part of global warming and climate change (Burić et al., 2018; Jacob et al., 2018; Malinović-Milićević et al., 2018), the respondents were asked what caused the increase in temperature. More than half of the respondents stated that the main cause is human activity, 32.7% of the respondents pointed out that human activities and natural cycles have an equal share in it, 9.6% of the respondents stated the cause were natural cycles, while 4.8% of respondents share neutral attitude. Related to the perception of vulnerability to climate change, we also examined the attitudes of the respondents regarding the percentage of their friends who believe that the increased carbon dioxide emissions caused by human activities affect climate change. The obtained results show that 28.8% of the respondents think it is up to 30% of their friends, while 63% of respondents think it is up to some 60%, and 8.2% of respondents think it is over 60% of their friends. In terms of the assessment of an activity which would best contribute to reducing carbon dioxide emissions into the atmosphere, 37% of the respondents preferred the use of renewable energy sources, 21.6% of the respondents chose the use of fossil fuels, 14.4% of respondents preferred to buy an electric car, 13.9% preferred recycling, 10.1% of the respondents opted for saving electricity, 1.4% of the respondents chose reducing air traffic, 1% of respondents were for using public transport, while 0.5% of respondents preferred growing organic food. Also, related to the perception of climate change vulnerability, we asked the question of the state of the natural environment in the place where they live, and most respondents, 74.5%, rated it as good, 21.6% of the respondents rated it as bad, 2.4% of respondents said it was very good, while, in contrast, 1.4% pointed out that the situation was very bad. Then, it was found that 91.8% of the respondents believe that the average temperature has increased in the last 100 years.
Examining the perception of the impact of climate change on the frequency and intensity of natural disasters (floods, droughts, stormy winds, etc.), 59% of the respondents believe that they have a significant impact, while 6.3% say that they do not affect at all. Then, 33.2% of the respondents believe that concerning the type of natural disaster that could befall them in the near or distant future because of climate change, floods are expected, 32.7% believe that these are heat waves, 24% that stormy winds can be expected, 7.2% expect landslides, and 2.9% expect droughts. Concerning the assessment of the level of vulnerability to natural disasters caused by climate change, 87.5% believe that they are endangered, while 1.4% believe that they are not endangered. When asked whether the frequency of natural disasters increased during their lives, the respondents mostly (83.7%) answered affirmatively, while the remaining 34 respondents (16.3%) answered that this was not the case. When asked about the distance of the respondents from the region where natural disasters can be expected, 100 respondents (48.1%) answered that the distance is 51–100 km, 46 respondents (22.1%) answered that it was 0–25 km, 44 respondents (21.2%) answered 101–250 km, while 18 respondents (8.7%) stated that their distance from the potential focus of the disaster is 26–50 km. About 91.8% of respondents believe that the floods that hit our region in 2014 were caused by extreme rainfall because of climate change.
The results of the t-test show that there is no statistically significant difference in the results between men and women in terms of knowledge about climate change (p = .506), assessment of vulnerability to climate change (.507), and perception of the climate change impact on natural disaster intensity (.341) (Table 3).

The analysis of the obtained results (one-way ANOVA) shows that there is a statistically significant difference between the mean values in the assessment of knowledge about climate change (F = 31.38, p = .000), the perception of vulnerability (F = 22.36, p = .000), and the perception of the climate change impact on natural disasters (F = 23.68, p = .000). In further analysis, it was found that the respondents who have completed higher education (M = 3.03, SD = .383) assess their knowledge about climate change to a greater extent than the respondents with completed primary school (M = 1.81, SD = .404).
The respondents who have completed doctoral studies (M = 3.18, SD = .795) assess the vulnerability due to climate change to a greater extent than the respondents with completed primary school (M = 1.45, SD = .522). Also, it was found that respondents who have completed master’s studies (M = 3.52, SD = .506) responded that climate change affects the intensity of natural disasters to a greater extent than it is believed by the respondents who have completed high school (M = 2.61, SD = .656). It was found that there is no statistically significant difference between the mean values of these groups of marital status and knowledge about climate change (F = 2.76, p = .029), but there is a statistically significant correlation with climate change vulnerability assessment and the perception of climate change impact on natural disaster intensity (F = 5.24, p = .06). In further analysis, it was found that married respondents (M = 2.56, SD = .88) assess the level of vulnerability due to climate change to a greater extent than those who are not in a relationship (M = 2.51, SD = .90). Also, it was stated that the respondents who are not in a relationship (M = 2.95, SD = .83) believe that climate change affects the intensity of natural disasters to a greater extent than it is believed by the respondents who are divorced (M = 2.73, SD = .76) (Table 4).

Discussion
Scientists around the world have examined the effects of many factors on the perception of climate change and come up with consistent and inconsistent results (Lee, Markowitz, Howe, Ko, & Leiserowitz, 2015; Nisbet & Myers, 2007). Examining the factors influencing public perception of climate change and its impact on natural disasters, the results of multivariate regression analysis
showed that education level was the most effective predictor of the perception of vulnerability to climate change, perception of the impact on natural disaster, knowledge about climate change and fear scores. The obtained research results are consistent with the results of the research in which it was determined that education is the factor most closely associated with the awareness of the impacts of climate change (Knight, 2016; Linnekamp, Koedam, & Baud, 2011; Nisbet & Myers, 2007; Monroe, Plate, Oxarart, Bowers, & Chaves, 2019; Owusu, Nursey-Bray, & Rudd, 2019). Namely, it was determined that faculty-educated respondents assess their knowledge about climate change to a greater extent than the respondents with completed primary school. Also, it has been found that with the increase in the level of education, the perception of the threat of climate change grows. Married respondents assess the level of their vulnerability to a greater extent than those who are not in a relationship. It can be assumed that they think more about their family or get more informed because of the fears of the mentioned (Lee et al., 2015; Nisbet & Myers, 2007). Also, it was found that respondents who are not in a relationship emphasize to a greater extent that the consequences caused by climate change affects the intensity of natural disasters. It can be assumed that the mentioned respondents have a higher level of knowledge, bearing in mind that Cvetković (2016) showed that the respondents who are not in a relationship know better what to do after an official warning about the flood. Also, it was found that the respondents who are divorced have not been prepared yet, but intend to get prepared in the next 6 months. Certainly, the results of many studies have identified significant influences of socio-demographic characteristics, such as age, gender and wealth, access to information, or civic engagement on the perception of climate change (Semenza et al., 2008; Shi et al., 2015; Yu et al., 2013). In the results of our research, besides the level of education, it was found that employment status affects the perception of vulnerability to climate change, while age affects the perception of climate change. We did not find that gender affects none of the examined dimensions of the perception of climate change, which is similar to the results of the research by Bollettino et al. (2020). Ballew, Pearson, Goldberg, Rosenthal, and Leiserowitz (2020) showed that political polarization in climate change views increases with higher education and income and positive employment status. In some other research, age has been found to have a weak influence on climate change perception (Hesed & Paolisso, 2015; Howe, Mildenberger, Marlon, & Leiserowitz, 2015). Our research has not shown a link between gender and perceptions of climate change, as certain studies point out that women and ethnic minorities are more likely to accept that climate change is taking place and that it is a significant threat (Hornsey, Harris, Bain, & Fielding, 2016; Macias, 2016). To understand climate change research, governance, and decision-making, adults get most of their news from radio, television, and print media and rely on the interpretations of scientific results (Ruiz et al., 2020; Shi et al., 2016). In our research, we found that most of the respondents trust scientists, followed by the media, while the least trust government officials when they report on climate change.
The obtained results showed that most respondents assess to know about climate change. Hoffmann and Muttarak (2017) found that non-formal education, like disaster training and drills, is positively linked with increased resilience and perception. In very interesting research, Bollettino et al. (2020) asked respondents about the links between climate change and their experience with natural disasters. Their results showed that almost half of the total number of the respondents agreed that the natural disasters they had experienced were due to climate change. Also, we have found that most respondents believe they are at risk from natural disasters caused by climate change. Concerning the causes that lead to climate change, most respondents point out that human activities are the main cause of climate change, which is consistent with the results of
research conducted in other countries (Alvi, Nawaz, & Khayyam, 2020; Doloisio & Vanderlinden, 2020; Singh, 2020). It was also determined that most respondents would use renewable energy sources to reduce carbon dioxide emissions, which is expected given that producing energy from renewable sources in Serbia is in its initial phase (Golusin, Tesic, & Ostojic, 2010).
Conclusion
Understanding people’s perceptions of climate change is not mere research but a necessary and obligatory precondition in creating and devising adaptation strategies to climate change. In our study, it was found that respondents are aware of climate change, but the dimension of objective knowledge of the processes, causes, and consequences of climate change is insufficiently examined. Most respondents are well acquainted with the connection between climate change and natural disasters, but it remains to examine several dimensions that can provide a clearer understanding of such impacts. All the strategies to mitigate the causes and consequences of climate change are rooted primarily in a comprehensive understanding of behavioral dispositions. Policies and strategies to improve people’s awareness of climate change, and campaigns to reduce the causes that lead to the negative consequences of these phenomena must very precisely consider the different demographic and socio-economic characteristics of people in the areas where they are implemented, or their success will be insufficiently guaranteed. In the following research, it is necessary to conduct comprehensive multi-method research, which should include a larger number of respondents from different parts of the country.
