Celebrities, sportspeople, climate experts and social media users worldwide adorned blue and red on Show Your Stripes Day 2025 to highlight the rapid warming of the climate.
The annual day of climate awareness, when people worldwide are asked to share climate stripes for their cities or countries to show how their homes are warming up, took place on Saturday, 21 June.
The climate stripes show the change in average annual global temperatures since 1850. Red stripes indicate hotter years and blue stripes indicate cooler years, against the average of the period 1961-2010.
The stripes were shared by: 
Formula E team Envision Racing, whose electric cars were emblazoned with the climate stripes at a race in Jakarta, Indonesia. Envision Racing shared the climate stripes on their social pages.
Sustainable fashion brand House of Tammam hosted a summer solstice hootenanny at Soho’s Yamaha store to recognise Show Your Stripes Day, which featured speeches and performances from a range of musical artists, activists and scientists.
TV stations across the USA, including ABC10, CBS News, WFLA and AccuWeather, shared and explained the climate stripes graphics. International media coverage of Show Your Stripes Day from The Times, Earth.org, Hong Kong Free Press, LiveNowFOX and Climate Central.
On social media, rock band Enter Shikari, TV personality Deborah Meaden and many other shared the stripes using #ShowYourStripes.
In the sporting world, the stripes were featured across Henley Women’s Regatta, with University of Reading rowers wearing climate stripes wristbands; various vehicles at the London to Brighton EV rally and the Cycling4Climate cycle tour in the Netherlands featured the climate stripes; and the blue and red could be seen at the Running4Climate climate marathon in the Netherlands.
On campus, visitors to the University of Reading’s Open Day had the opportunity to play Climate Station, an immersive PlayStation 5 (PS5) and PlayStation VR2 (PS VR2) experience that puts users face-to-face with our changing planet.
Professor Ed Hawkins, the University of Reading climate scientist who created the climate stripes, said: “The climate stripes make complex climate data instantly understandable - anyone can see how their local area has warmed just by looking at the colours. They can be easily shared across platforms and industries, which is why we see them on racing cars, social media, and TV broadcasts. They help start important conversations about climate change in every corner of society. Thank you to everyone who participated in Show Your Stripes Day 2025."
Stripes for cities, countries and continents have all been updated using 2024 data and can be viewed and downloaded at showyourstripes.info.
