Climate warming stripes

Communicating climate change can be a challenge, but the 'warming stripes' created by Climate Scientist and Society Fellow, Professor Ed Hawkins (University of Reading) is a brilliant way to do it.

Ed's simple visualisation has no words, no numbers, no graphs, it is simply a series of vertical coloured bars. Each bar, or stripe, represents the average temperature for a single year relative to the average temperature over the period as a whole. The blue stripes show when the average temperatures have been below average and the red stripes when temperatures have been above average.



In just a glance, the stripes paint a very clear and striking picture of how global average temperatures are rising rapidly, as the bars shift from mostly blues to mostly reds.

Ever since the stripes were created in 2018, they have been used globally to communicate the rapid rise in global temperatures that has been taking place in recent decades.


Global warming stripes
The warming stripes for the globe as a whole reveal a band of deep reds on the right-hand side of the graphic, which shows the rapid heating of our planet that has taken place in recent decades


One region that is warming faster than anywhere else is the Arctic. Research has shown that the Arctic is warming around 4 times faster than the global average. The warming stripes for the Arctic Ocean (below) are visually striking, with the block of deep reds in recent decades showing just how fast the temperatures here have been rising.

A recent report published by the World Meteorological Organization and the Copernicus Climate Change Service, has shown that Europe is the fastest warming continent in the world. The warming stripes for Europe (below) clearly show this rapid warming that has been occurring in recent decades.

The warming stripes are already having a massive impact. More than a million people downloaded graphics from the site within a week of its launch in 2019 and since then they have been used worldwide, gaining iconic status.

The summer solstice in the northern hemisphere, 21 June, is #ShowYourStripes day. Meteorologists and scientists around the world will share the warming stripes to start conversations about climate change, promote awareness of the climate crisis, and stress the urgent need to take action now.



The graphics are free to use and have already been used in a variety of ways to raise awareness of climate change. The stripes have appeared on the Main Stage at the Reading Festival, on badges worn by US senators, at school climate strikes, and on electric cars, trams and trains. They have also been printed on clothing, mugs and scarves as well as on the shirts of Reading football team.
