Inside the IPCC explores the institution of the Intergovernmental Panel on Climate Change (IPCC) by focusing on people's experiences as IPCC authors. While the budget and overall population of an IPCC report cycle is small, its influence on public views of climate change is outsized. Inside the IPCC analyzes the social and human sides of IPCC report writing look like, as a complement to understanding the authoritative reports that underwrite policy decisions at many scales of governance. This study shows how the IPCC's social and human dimensions are in fact the main strength of the organization. By stepping back to reveal what goes into the making of climate science assessments, Inside the IPCC aims to help people develop a more realistic, and thus, more actionable, understanding of climate change and the solutions to deal with it.
