Analysing the construct ‘geoengineering on Wikipedia’
Nils Markusson
CEC14, Berlin, Aug 2014
intro
• Definitions and classifications are fluid and
contested
• How to study their construction in public
discourse?
• Wikipedia offers an opportunity
– Highly public (few-to-many)
– Topology (linked labels) ideal for this question
– Heterogeneous, contextualised, longitudinal
methods
• Collaboration with researchers in Paris and Barcelona
• Dataset 1: geoengineering in climate change network
• Dataset 2: context and structure– Selected 34 start articles, followed in and out links, resulted in a set of
1155 articles
• Dataset 3: history– Manually looked into history of the 34 geoengineering related
Wikipedia pages, including both content and links
• Data collected June 2013

results
two groups: ‘core’ and ‘land-based’• ‘Core’: main article, SRM, OF, WM…• ‘Land-based’: BECCS, biochar… (varies by resolution)• Weakly connected, competing
different contexts- Core ↔ science; Land-based ↔ technology- Core far from climate policy- A few military categories
roots include terraforming and planetary engineering
• resists the seductive simplicity of stated definitions and classifications and makes visible informal aspects of discursive practice
• resists tendencies towards decontextualized and ahistorical presentation in the discourse on geoengineering
• can usefully be contrasted with the de facto definitions and classifications
resistance of the medium
visualisation
• Lists, diagrams, networks
• Network graphs (gephi) crucial
– Analysis and interpretation
– Overview, complexity, zooming
– Fits with the fluidity of de facto definitions
