“Communicating the Links Between Climate Change and Heat Waves with the Climate Shift Index”
Yale University’s Program on Climate Change Communication has published a new study on the effectiveness of communicating the links between climate change and extreme weather. Study authors Laura Thomas-Walters, Matthew H. Goldberg, Sanguk Lee, Aidan Lyde and Anthony Leiserowitz conclude that the connection may be most effectively communicated using percentages (“the heat wave was made at least 400% more likely by climate change”) than using equivalent magnitudes (“the heat wave was made at least 5 times more likely by climate change”).
