June 21 is #ShowYourStripes day — a time to spread awareness about climate change using the iconic ‘warming stripes’ graphics showing temperature trends over the last 100+ years.
Each colored stripe represents the annual average temperature relative to a long-term average.
Red stripes are years that were hotter than average; blue stripes are years that were cooler.
The strong red shift shows rapid warming in each city and across the globe.
