Wear a message about climate change with the ‘warming stripes’ created by Professor Ed Hawkins (University of Reading). They are visual representation of the change in global temperature over the past 100+ years (1850-2021). Each stripe represents the temperature that the world averaged over a year. Please note that due to the nature of all-over printing on fabric, some stripes get folded into the seams.
