"I recognize the right and duty of this generation to develop and use the natural resources of our land, but I do not recognize the right to waste them, or to rob, by wasteful use, the generations that come after us." - 26th U.S. President Theodore Roosevelt 

C3 at Cogsci 2014

July 24, 2014

C3 Postdoc Timothy Gann gave a well-attended talk at the Cognitive Science Conference entitled "The Semantics of Climate Change and Global Warming." In it he discussed how these terms, despite their frequent synonymous use in the media, are sometimes associated with different concepts in highly partisan media. 

Here is the talk's abstract:

Creating consensus and facing the challenges of climate change requires effective climate communication. However, consensus about issues relating to climate science is unlikely to happen when there isn’t a clear public consensus about which name is more appropriate, “climate change,” or “global warming,” and what those terms mean. Previous research has shown that perceptions of these terms varies, depending on factors such as the audience’s political affiliation. To investigate this further, we analyzed two corpora from partisan online news using a high dimensional semantic analysis. This study found that while there is substantial semantic overlap between the terms “climate change” and “global warming,” there is less overlap in the conservative media corpus. The results also show that there was a larger proportion of conservative articles that preferred to use “global warming” exclusively, whereas progressive articles tended to use “global warming” to supplement “climate change.”
