I urge every climate change science communicator (including anyone speaking to family and friends and colleagues) to heed these warnings. Do not follow the example of the scientist who communicates all the details and background first and then announces the results and conclusions at the end. In journalism, this sin is called “burying the lead.” Avoid metric units when speaking to Americans. Avoid unfamiliar terms that always have familiar substitutes. Rather than “anthropogenic,” you could and should say “human caused.” Do not use jargon. Try to compose messages that are simple and memorable, to repeat them often, and to partner with trusted messengers. Use metaphors and other vivid imagery. If climate change is important to you, do not speak or write about it in dry and unemotional language that conveys boredom and resignation. Instead, let your passion show. Profit from opportunities to learn from expert communicators and to get useful feedback. Nobody is born knowing how to ski or drive a car. Like these skills, communication skills can be taught, developed, practiced, and improved.
