Verified data175 years of a warming world
Each stripe is one year's global temperature from 1850 to 2025 — blue for cooler, red for hotter than the pre-industrial average. The ten hottest years on record have all come since 2015.
CSV · 176 rows · 1850–2025
Global temperatures have risen about 1.5°C above the 1850–1900 pre-industrial average, with 2024 the hottest year on record. Every one of the ten warmest years has occurred since 2015.
Key findings
- The world has warmed about 1.5°C since the 1850–1900 pre-industrial average.
- 2024 was the hottest year on record; the ten warmest years have all come since 2015.
- The stripes shift from mostly blue before the 1980s to deep red today.

Global near-surface temperature anomaly
Accessed Aug 22, 2026
Annual global mean anomaly vs the 1850–1900 average; 'warming stripes' design after Ed Hawkins.
Methodology
Global mean near-surface temperature anomaly each year relative to the 1850–1900 (pre-industrial) average, from the Met Office Hadley Centre HadCRUT5 dataset, distributed via Our World in Data. Shown as “warming stripes” — one coloured stripe per year (design after Ed Hawkins) — so colour alone carries the trend.
What this does not show
Colour shows each year's global average temperature relative to the 1850–1900 average, not absolute temperature. Annual global means smooth over large regional and seasonal swings. 2026 is excluded as an incomplete year. The “warming stripes” concept is by climate scientist Ed Hawkins.
