How do elite policy actors get information, what do they believe?• Surveys in 2010, 2016 and 2017
• Who are your “sources of expert scientific information about climate change”?
• Human activities are an important driver of current global climate change (Anthropogenic)
• There should be an international binding commitment on all nations to reduce GHG emissions (Binding)

Methods: Exponential Random Graph Models
• Accounts for the interdependence of ties through specified terms (MCMC)

Methods: Exponential Random Graph Models
• Accounts for the interdependence of ties through specified terms (MCMC)
• Interpret like a logistic regression (coefficients in log-odds)

Methods: Exponential Random Graph Models
• Accounts for the interdependence of ties through specified terms (MCMC)
• Interpret like a logistic regression (coefficients in log-odds)
• Temporal model – stergm – runs two ERG models (formation and persistence)

Discussion
• Increasing doubt of ‘Anthro’ among policy elite
![Page 16: Echo Chambers in Climate Science€¦ · Echo Chambers in Climate Science Lorien Jasny, University of Exeter (L.Jasny@Exeter.ac.uk) And Dana Fisher, University of Maryland](https://reader036.fdocuments.us/reader036/viewer/2022071210/602179f688b59632fa6cbe70/html5/thumbnails/16.jpg)
Discussion
• Increasing doubt of ‘Anthro’ among policy elite
• Echo chambers switch from ‘Binding’ to ‘Anthro’
![Page 17: Echo Chambers in Climate Science€¦ · Echo Chambers in Climate Science Lorien Jasny, University of Exeter (L.Jasny@Exeter.ac.uk) And Dana Fisher, University of Maryland](https://reader036.fdocuments.us/reader036/viewer/2022071210/602179f688b59632fa6cbe70/html5/thumbnails/17.jpg)
Discussion
• Increasing doubt of ‘Anthro’ among policy elite
• Echo chambers switch from ‘Binding’ to ‘Anthro’
• Echo chambers significant at all measurable levels of ‘Anthro’

Discussion
• Increasing doubt of ‘Anthro’ among policy elite
• Echo chambers switch from ‘Binding’ to ‘Anthro’
• Echo chambers significant at all measurable levels of ‘Anthro’
• Echo chambers significant in adding new ties

Conclusion
• Information is politically selected
• Information network is getting more polarized
• Increasing doubt of Anthro -> echo chambers don’t drive out minority viewpoints
