“Warming Stripes” may be one of the most impactful visualizations of climate change. The colors reflect the scientific truth of warming, and are from the same palette as the American flag (red, white and blue), communicating the political imperative to act. What I especially appreciate about “Warming Stripes” is how, in the fine print, the methodology for collecting (and excluding) data is clearly disclosed. And, sadly, the movement to deny climate change has produced a counterfeit version of this visualization by only selecting the data points that support their opinion.
