June 21st is #ShowYourStripes day

#ShowYourStripes day is coming up — on June 21st, the summer (or winter) solstice in the Northern Hemisphere — a day to spread awareness about climate change using the iconic warming stripes graphics that show temperature trends over the last 100+ years.

A series of vertical colored stripes representing global annual average temperatures from 1850 to the present. The colors transition from deep blue (cooler years) on the left to deep red (hotter years) on the right, visually illustrating the steady rise in global temperatures over time.

Planet warming is accelerating

Global temperatures are on the rise, shattering numerous records in 2024. It appears we’ve already surpassed the critical 1.5°C threshold set by the Paris Agreement, much earlier than climate models anticipated.

The essence is simple: greenhouse gases trap more energy on our planet, leading to higher temperatures, which in turn fuel weather events.

Charts illustrating this trend are unmistakable.

Chart of global surface temperature anomalies versus pre-industrial levels, 1940 to 2024, with 2023 and 2024 above the 1.5°C Paris limit.
