About me

Dr Jordan Harold

I am interested in how individuals interpret scientific evidence about climate change, and how evidence can be communicated to support societal decision-making. A key aspect of my current work is understanding the interlinkages between people’s cognitions and behaviours and policy responses to climate change that would enable societal transformation.

As an applied cognitive psychologist at the University of East Anglia and Tyndall Centre for Climate Change Research, I connect insights about how people think and make decisions with real-world practical applications. I employ a range of methods in my work, including experiments, eye-tracking, decision-making tasks, surveys and interviews.

Through my recent work with the Intergovernmental Panel on Climate Change (IPCC), I have supported the visual communications design of the IPCC Special Reports on Global Warming of 1.5oC and Climate Change and Land (as a drafting author to the Summaries for Policymakers).
