Social media have become a primary mode of communication in all aspects of life, including science. The panel will consist of scientists and science journalists who are adept at this mode of communication. In opening remarks, each panelist will provide guidelines about how to best use social media, with an emphasis on Twitter, to communicate information on climate and climate change with high accuracy to a broad audience. These opening statements will be followed by questions from and discussions with the attendees. The goal is to encourage and enable more atmospheric scientists to interact with the public and news media in clearly communicating science - including a basic understanding of scientific processes as well as interpreting new results and observations.
