Political economy, media, and climate change: sinews of modern life

In this 21st century, examining how climate change is described and considered, largely through mass media, is as important as formal climate governance to the long-term success or failure of efforts to confront the challenge. Mass media stitch together formal science and policy with the public sphere. And many dynamic, contested factors contribute to how media outlets portray climate change. This paper addresses contemporary political economicsfrom greater workloads and reductions in specialist science journalism to digital innovations and new media organizational formsas they relate to media coverage of climate change. By way of recent studies and indications of these dynamics, we appraise how power flows through culture, politics, and society, to construct coverage, public discourses, and knowledge on climate change. In so doing, we explore how media representations of climate change have changed over time, and particularly how the rise of digital media has reshaped climate coverage. Considerations of climate change, arguably the most heavily politicized scientific issue at the turn of the new millennium, seek to inform and anticipate corollary science issues, such as ongoing concerns for genetically modified organisms, nanotechnology risks, and increased threats to water quantity and quality. The focus on political economythe sinews' of modern lifecan also then help to inform perceptions and decision making in associated environmental challenges. (C) 2013 John Wiley & Sons, Ltd.
