To help demystify and open up conversations about climate change, The Third Pole has compiled this glossary of key terms, available in five languages. As the world warms due to climate change, threatening millions of lives and livelihoods, there is nothing more urgent than communicating clearly about the changing climate and its impacts. But discussions about climate change are too often heavy on jargon and technical terms, excluding the wider public from conversations that are meaningful for changing lives. But we cannot abandon precision and scientific rigor. A thorough understanding of key terms related to climate change is essential for the public to understand what is happening to our environment – and to think critically about how governments and powerful interests are responding. That’s why Third Pole has produced this Climate Change Glossary, a guide to key terms in the climate conversation. We hope it will help broaden understanding of climate change and help those most affected add their voices to the discussion. This guide is available in English, Hindi, Nepali, Urdu and Bengali and will be updated regularly as new terminology enters the climate change debate. Words in bold are terms that are explained elsewhere in this glossary. (Shalinee Kumari)
