Lecture 4: Climate Change Flashcards
NASA GISS, GISS TEMP (1800-2017)
- Most countries WERE between -1 degrees and 0 degrees in 1880
- Most countries are now between 1 degree and 1.5 degrees (2017)
Why is the difference between 1.5 and 2 degrees important?
Limiting global warming to 1.5 degrees, compared to 2 degrees, could reduce the number of people both exposed to climate related risks and susceptible to poverty up by several hundred million by 2050
(IPCC, 2018)
Give an example of the importance of the difference between 1.5 and 2 degrees
Extreme weather
- 1.5 degrees = 100% increase in flood risk
- 2 degrees = 170% increase in flood risk
Steps necessary for 1.5 degrees
IPCC (2018): this data shows how quickly the global degree needs to drop to keep in 1.5 degrees - there is a cliff face drop that needs to take place to remain in 1.5 degrees. Need to half emissions in the next 10 years to keep on the 1.5 trajectory
Psychologies contribution to addressing climate change (1-3)
- researching and promoting public understanding and engagement
- insights into peoples perceptions of CC
- reducing emissions from peoples choices and behaviours.
Psychologies contribution to addressing climate change (4-6)
- systems that result in climate change are also underpinned by peoples decisions and actions - wider political contexts (consumerism)
- beyond ‘behaviour’- people as agents of change
- supporting adaptation and coping with CC - mental health and eco-anxiety
Poortinga et al., (2019)
European social survey asking questions about Ps perception towards CC
Results:
- the reality of CC is now accepted by everyone
- CC has mainly been caused by humans
- Lower numbers of the impacts being bad
Capstick et al., (2019)
Survey assessing how worried people were about CC
- assessed UK representative sample with the aim to gauge the level of UK concern about CC
- 1/5 say that they are extremely worried
- majority of people showing concern and worry
When asking people how concerned they are about CC
- 52% respond with “very concerned”, 33% responded with “fairly concerned”
What determines Awareness and Concern?
- Science, facts and information
- Role of values
Evidence of science determining awareness/concern
Ming Lee et al., (2015):
- assessed whether CC awareness and concern is determined by knowledge and information.
Results:
- found that more developed countries had more awareness and concern of CC compared to Africa, at this time, being more variable
In terms of basic awareness, they identified possible predictors (education, communication, access, other).
- They found that the main predictor was EDUCATION
They also assessed CC risk perception, with predictors of CC risk being:
1. cause of global warming
2. local temperature perception
- Findings show that developed countries risk of CC was due to knowing the causes, whereas less developed countries (Africa and Asia) used local temperatures as a guide to risk perception
Ming et al., (2015) conclusions
- Worldwide educational attainment is the single strongest predictor of CC awareness
- Understanding the anthropogenic causes of CC (human actions) is the strongest predictor of CC risk perceptions
Evidence of the role of values determining awareness/concern
Shi et al., (2016)
Shi et al., (2016): found that knowledge of the cause and consequence of CC were important influences on concern. ALSO biospheric values (values centred on the concern about nature) was important influences about concern about CC.
Evidence of the role of values determining awareness/concern
Lorenzoni et al., (2006)
Asked Ps what their first image was to come to mind when saying the word “Climate change” between US and UK Ps.
Results:
- US most prominent image was ice melting
- UK most prominent image was weather, global warming, and ozone
IMPORTANTLY - images categories that weren’t present are important:
- health
- justice
- politics
- history
- the future
- the urgency
- action
Gifford et al., (2011) Barriers to attitude change
7 psychological barriers to attitude change
1. limited cognition
2. ideologies
3. other people
4. investments
5. discredence
6. perceived risk
7. limited behaviour
“Dragons of Inaction”
Almost all evidence suggests that many people are aware of the CC crisis, BUT do they care? (2 viewpoints)
- Psychological Distance
- Availability Heuristic
