GC Insights: Communicating changes in local climate risk using a physically plausible causal chain

Ed Hawkins, Nigel Arnell, Jamie Hannaford, and Rowan Sutton

Abstract. Directly linking greenhouse gas emissions or global warming to experiences of local climatic changes or extreme events is a potentially important communication tool. We develop a physically plausible ‘causal chain’ as one approach to demonstrate the connections between global carbon dioxide emissions and real-life events, using a case study of flood risk in one river basin in the UK.

Short summary
Climate change can often seem rather remote especially when the discussion is about global averages which appears to have little relevance to local experiences. But, those global changes are already affecting people, even if they don’t fully realise it, and effective communication of this issue is critical. We use long observations and well-understood physical principles to highlight how global emissions influence local flood risk in one river basin in the UK.
