A researcher has found a new way to chart Earth’s warming temperatures, one that he believes paints a clearer picture of a changing climate.
Ed Hawkins, a climate professor at the University of Reading in the U.K., created “bar code charts” that show rising temperatures as colours. The result is a snapshot of how much warmer, on average, the world has been getting, particularly in the last decade.
He made this one showing average global temperatures since 1850.
Inspired by this, CBC News made similar charts for several Canadian cities using data from Environment and Climate Change Canada. Each stripe represents the average temperature for a year. The deeper the blue, the colder is was that year. Reds indicate warmer temperatures.
