The more you read about climate change, the more you learn and become comfortable with the vocabulary, which is sometimes so specific to the subject that it takes a while.
For example, what does mean when people talk about carbon sink as opposed to carbon sequestration? What are the differences and relationships between greenhouse gases and CO2? How is climate change different from global warming? To simplify and clarify, we have also listed in this glossary some of the most commonly used words (like sustainability and resilience), phrases (like negative emissions or tipping point), and acronyms (like IPCC and GHG), which crop up regularly in the literature.
