• Optimism bias• Temporal discounting, psychological distance
What influences our perceptions of
climate change?
Direct experience and climate change perceptions
•Direct experience usually more important for shaping risk perceptions than second-hand (mediated) information (Slovic, 2000)
•But… no difference between flood victims and non-flood victims in perceptions of climate change (Whitmarsh, 2008)
•But we experience weather, not climate (change); and the issue is highly politicised… so direct experience not persuasive by itself
Whitmarsh, 2008
Direct experience is mediated through values
Clayton et al., 2015. Nature Climate Change
“Much diversity in [public] understanding can be attributed not to what we learn about climate change but to how, and from whom, we learn: the sources of our information and how we evaluate those sources”
E.g., •People who believe
climate change is not happening are less likely to remember (accurately) that they had experienced a warmer-than-usual summer during the previous year (Howe & Leiserowitz, 2013)
Why are some people sceptical about climate change?
Climate change attitudes are ideological

Climate scepticism score
Political affiliation:
• Values (individualism, right-of-centre politics) and behaviour (energy-intensive lifestyles) are significantly correlated with scepticism
• Denial can be a coping response to threatening information (e.g., Carver et al., 1989)
• Is climate scepticism an identity protective response to threatening information. i.e., would people believe in climate change if it didn’t threaten their way of life/identity?
• Two studies: hypothetical risk (student sample) and climate change (UK sample), comparing risk info. with vs. without behaviour change message

Scientists warn of UK climate risks
Britain will experience water shortages and flooding by the end of the century if temperatures are left unchecked, analysis shows.Nearly 18 million British people will experience more water shortages and 160,000 will be affected by coastal flooding by the end of the century if temperatures are left unchecked, according to new analysis.The data, which was launched at the UN climate talks in Durban, shows all 24 countries included in the report have warmed since the 1960s and the frequency of extremely warm temperatures has increased, while very cold temperatures have become less frequent.The latest warning on the impacts of climate change comes in the wake of one of the driest years on record in some parts of Britain. Many areas are likely to see an increase in the frequency of droughts and water scarcity, the report says.In the worst-case scenario painted in the report, food production could decline dramatically in many parts of the world. The new analysis suggests climate change could be worse than previously thought. By the end of the century, it says, about 49 million more people could be at risk from coastal flooding due to sea level rises."Life for millions of people could change forever. This makes the challenge of reducing emissions ever more urgent," said UK climate and energy secretary, Chris Huhne.Substantial cuts in carbon emissions could come from changing our behaviour. Ministers are currently considering proposals to drastically reduce transport and energy consumption. These proposals could mean 80% reduction to travel and similar cuts in energy used in homes. Prices for many products will probably increase under the new plans, while certain products will be phased out altogether.
“Britain will experience water shortages and flooding by the end of the century if temperatures are left unchecked, analysis shows... Food production could decline dramatically …”
Behaviour change [no BC] condition:“Substantial cuts in carbon emissions could come from changing our behaviour [changing the way products are made]. Ministers are currently considering proposals to drastically reduce transport and energy consumption [transform transport and energy supply].
These proposals could mean 80% reduction to travel and similar cuts in energy used in homes. Prices for many products will probably increase under the new plans, while certain products will be phased out altogether [introduce new transport technologies and home appliances. These new plans will mean alternative energy sources will be funded and industry processes will be transformed].”

Study 1. Scepticism as identity threat response
• Perception of climate risks DECREASED and climate scepticism INCREASED when given risk information mentioning need for behaviour change
How bad are climate risks? Climate change claims are exaggerated

Does it matter what other people are
doing (and who they are)?
Climate change as a collective problem
Most psychological research on climate change perceptions and action has focused at the individual level
• Policy / campaigns also often focus on individual responsibility
Yet climate change is a fundamentally collective problem
• Social / commons dilemma; cf. diffusion of responsibility • Perceived lack of action by others and low self-efficacy
Sweetman & Whitmarsh, 2016
Climate change as a moral problem
Perceived fairness is key to perceptions of climate change action
• Qual. work on climate change perceptions shows morality and esp. equity are central themes (Whitmarsh, 2009) - those with more power, wealth, liability (industry, US, rich…) should take more responsibility
• Acceptability of (climate change) policies determined by equity and fair distribution of costs (Upham et al., 2009); cf. psychological models of political action (van Zomeren et al., 2008)
• Progressive policies which require more from those more responsible/able to act expected to be fairer, thus more acceptable
Research Questions:
1. Is willingness to act on climate change predicted by perceived fairness or efficacy of the behaviours?
2. Do others’ actions influence willingness to act via the fairness and efficacy pathways? Does social status or group membership of these others matter?
Sweetman & Whitmarsh, 2016
Study 2. Methods
• 2 x 2 between-subjects (Study 1: N=129; Study 2: N=333; Study 3: 229):• Exemplar status (high = business CEOs vs. low =
homeless people) x • Exemplar group identity (ingroup = British vs.
outgroup = US)
Latest scientific findings provide further evidence of the significant risks posed by climate change for humans and ecosystems. We are interested in your views on actions to tackle climate change. Recently the US chamber of commerce, a body representing US business [The Big Issue UK, a street newspaper sold by homeless individuals in Britain] has introduced a climate change scheme whereby CEOs and other well-paid US business executives [homeless individuals selling the newspaper] will pay 15% of their annual salaries to the US CC [Big Issue] action on climate change project. The project has received broad support from US CC members [the homeless individuals selling the Big Issue]. Importantly, this project invests in developing technologies and services (e.g., renewable energy technology, energy efficiency projects, environmental management services) that are vital to tackling climate change.

Study 2. Results
Sweetman & Whitmarsh, 2016
How can we encourage low-carbon, climate-resilient lifestyles?
Attitude-behaviour gap… and HUGE challenge
•99% awareness of climate change•Most understand the role of human behaviour in causing climate change, and think it should be tackled
•BUT very limited behaviour change (mostly ‘small and painless’)
Whitmarsh, 2009; cf. Lorenzoni et al., 2007

Barriers to climate change action
• Climate change is a distant threat• Other things are more important• Uncertainty and scepticism• Reluctance to change lifestyles• Externalising responsibility and blame• Lack of knowledge about causes, consequences, potential solutions• Distrust in information sources• “Drop in the ocean” feeling • Fatalism (too late to act/ can’t do anything)• Technology will save us
Individual barriers
Social and structural barriers• Inaction by governments, business, industry• Free-riding (policy preference for voluntary measures)• Social norms and expectations• Lack of enabling initiatives and facilities (e.g., regular public transport)
Lorenzoni, Nicholson-Cole & Whitmarsh. 2007
How can we change behaviour?
Downstream – influencing individuals - information/advertising - modelling (social learning) and norm-based approaches
Upstream – influencing context/situation of action - economic measures - education (and changing social norms) - changes to available products and services - changes to built environment
• Both downstream and upstream required to address multiple barriers to lifestyle change (‘nudge’ techniques insufficient)
• Participatory democracy to involve public in policy design
Verplanken & Wood, 2006; Clayton et al., 2015
Towards low-carbon lifestyles
• Limited success of behaviour change policies• Piecemeal, individualistic, consumer approaches dominate
Taking up a new environmental behaviour may lead to adoption of additional, environmentally beneficial, behaviours
• From behaviour change to lifestyle change
• Theoretical support (e.g., self-perception theory) – but no coherent theory
• Some empirical support in health (Ross & Thow 1997), consumption (Simonin & Ruth 1998) and environmental (Whitmarsh & O’Neill, 2010) behaviours – but small samples, correlational, geographically limited

Study 4. Impact of the Welsh carrier bag charge
Need for relational studies and holistic interventions
Targeting interventions• High-emitting groups (e.g., high
earners, sub-urbanites)• Leisure/recreation practices • Organisations – e.g.,
telecommuting scheme led to 66% drop in vehicle miles
• Context change moments (habit discontinuity)
Relational approaches• Avoiding rebound effects• Behavioural spillover literature
highlights potential for broader lifestyle change (e.g., Whitmarsh & O’Neill, 2010)
Capstick et al., 2015
Need for relational studies and holistic interventions
Unexpected outcomes from interventions• Recent US study found taking
your own bags to the supermarket led to increase in purchase of organic food… and of unhealthy snacks! (Karmarker & Bollinger, 2014)
• Moral licensing effect??
Conclusions
• Climate change is a problem of human behaviour• It is a political issue – values (not experience or knowledge) drive
perceptions • More climate change information will not persuade the most sceptical
groups• Climate change messages can be deeply threatening – need to reframe• Willingness to act is influenced more by moral than ‘rational’ factors (e.g.,
efficacy)• Willingness to act also depends on the actions of (high status) others• Spillover may be a way to achieve more ambitious low-carbon lifestyle
change – if circumstances are right (e.g., priming identity)• Contextual factors may still be a stronger influence – hence, need for
structural interventions to achieve radical change (including adaptation)• Interventions should be targeted to high-emitting practices and sub-
groups, organisations and critical moments • Lifestyles are a ‘system’ – consider unintended consequences from
interventions and dynamics/relationships across individual behaviours
