This is a picture of a display outside the University of Maryland Center for Environmental Science on Solomon’s Island, Maryland. The x-axis represents the years 1938–2019. Each bar represents the average temperature of that year compared to the average of the average temperature of all the years combined. Years where the average yearly temperature was the same as the combined average temperatures are in white. Years whose average temperatures were less than the combined average are blue, and years whose average temperatures were greater than the combined average are red. The color of the blue and the red becomes darker the greater the difference from the average.
