Show Your Stripes Day 2025

TYLER, Texas (KLTV) — June 21 is Show Your Stripes Day, a day to bring attention to climate change through use of “warming stripes”. It is a global campaign, with stripes set to appear on landmarks, sports jerseys, cars, and more. Stripe visuals have been created for 195 U.S. cities, 49 states, the country, and the globe.

Ed Hawkins, Professor of Climate Science at the University of Reading, created warming stripes to be a visual of the long-term change in global temperatures. Each stripe represents a temperature average for one year compared to the long-term average for that city, state, country, etc. Red stripes are for years hotter than the average, blue stripes for the cooler years. The red shift in recent years reflects rapid warming in the last few decades.

These images have been provided by Climate Central, who compiled data from the National Oceanic and Atmospheric Administration (NOAA). Most locations analyzed show a warming trend, with the trend being most pronounced in areas such as the Southwest, Northeast, and Alaska.
