Our mission is to promote climate literacy by curating a comprehensive lexicon of key words, submitted by leaders in the discourse. Let’s talk about “climate”. Climate literacy is worryingly low. A 2021 survey found that less than 15% of respondents in Germany, France, Italy, UK and USA prove to be climate literate. Our goal is giving people the tools they need to talk about climate. Those with high climate literacy are more than three times as likely to make an active effort to tackle climate change. We are building the climate lexicon: a just and factual database, defined by pioneers in climate discourse. We invite frontline authors, scientists, Indigenous leaders, policy-makers, explorers and designers to select a word that is central to their climate work and define it in their own voice. We support each definition with factual information, photographic evidence, literature and resources for further learning.
