What is it about
This handbook, commissioned by the IPCC’s Working Group I Technical Support Unit, provides practical, evidence-based principles for effective climate communication. It distils social science insights into six key practices: be a confident communicator, talk about the real world not abstract ideas, connect with audience values, tell human stories, lead with what you know, and use effective visuals.
When to use it
To guide scientists, policymakers, and reformers in explaining climate science clearly.
For structuring public engagement, presentations, or policy discussions.
To make climate communication more relatable, evidence-based, and impactful.
