‘warming stripe’ graphics are visual representations of the change in temperature as measured in each country over the past 100+ years. Each stripe represents the temperature in that country averaged over a year. For most countries, the stripes start in the year 1901 and finish in 2020.

The stripes turn from mainly blue to mainly red in more recent years, illustrating the rise in average temperatures in that country.

You can generate warming stripes for most countries and for some cities around the world using this brilliant generator. The graphics have a  CC-BY 4.0 license, so can be used for any purpose as long as credit is given to Professor Ed Hawkins (University of Reading) and a link is provided to the #ShowYourStripes website.
