Twitter and climate change

Abstract

Abstract Twitter provides a useful tool for studying public conversations about climate change, an issue that crosses international boundaries and stirs political and scientific debate. This review presents what is currently known about the way climate change is discussed on Twitter, acknowledging advantages and limitations and suggesting future areas for study. As an accessible platform, Twitter allows public expression of opinions on climate change and provides data on how these fluctuate over different times and places. Moving forward, studies assessing climate views can be improved by better linking them to demographic and other data indicating the population that Twitter users represent. The open‐ended content of tweets provides additional information, such as which topics are associated with climate change and which terms are used to discuss it. Future studies can build on these results to capture a wider range of climate‐related discussion. Finally, researchers are using Twitter to understand who initiates and participates in climate change dialog and how, by categorizing users as different actors—such as politicians, celebrities, NGOs, or the general public. Future research could consider how effective these efforts are, and how Twitter activity translates to offline outcomes.
