How a colorful graphic indicates a global warming trend

The first day of summer is also Show Your Stripes Day.
The observance was created in 2018 to raise awareness of climate change. At the center of the effort is a colorful graphic called "Warming Stripes."

According to Climate Central, a nonprofit independent group of scientists and communicators, the concept was created by climate scientist Ed Hawkins. It features lines of various shades of blue and red that are stacked left to right, indicating how temperature has changed for a given location over a certain amount of time. Blue represents a cooler-than-average year, while red represents a warmer-than-average one. Darker colors represent a bigger departure from the average.
In the example below, the stripes represent the global temperature change from 1850 on the left to 2023 on the right. The bulk of the world’s warmest years in the past 173 years have happened in the past few decades.
