A decade ago, when we ranked the most controversial articles on Wikipedia, George W. Bush topped the list, and global warming ranked fifth.

The article on global warming has now been relabeled climate change, but it remains one of the most divisive topics of our time, and one often discussed on social media.

Make no mistake: we are great fans of social media and arguably tweeted this article when you read it.

This may be attributable to the way that climate change is often portrayed primarily as a political issue: something one can choose whether one wants to support it; something that all will see as a political issue.

At a time when so much is unclear, we are sure of one thing: the significance of experts.

Social media can be regarded as a marketplace of ideas that offers an open forum to share facts and opinions and, importantly for academics, to educate the public about their research.

Our recent research, published in Climatic Change, demonstrated how tools such as computerised theme modeling and mood analysis can be used to monitor public discourse on such topics as climate change, nutrition, and climate politics.

Politicians and policymakers have long tended to avoid culturally controversial issues, and polarization of public opinion has been proven to weaken leaders “accountability when deciding big things.
