Warming stripes (sometimes referred to as climate stripes or climate timelines) are graphics that use a series of chronologically ordered coloured stripes to visualize trends in the temperature record of Earth. They employ a minimalist style, avoiding technical distractions by using colour alone to intuitively convey trends in global warming to non-scientists. The initial concept of visualizing historical temperature data has been extended to use animations, to visualize sea level rise and predictive climate data, and to visually juxtapose temperature trends with other data series, such as the concentration of carbon dioxide in Earth's atmosphere, global glacier retreat, precipitation, the contribution of aviation emissions to global warming, and biodiversity loss. These warming stripes were published by the British climatologist Ed Hawkins in 2018, using data from the World Meteorological Organization. The colours represent the annual mean global temperature for each year from 1850 (left) to 2018 (right) – the progression from blue (cooler) to red (warmer) stripes is indicative of global warming.Graphic credit: Ed Hawkins
