2025 was the world’s third-hottest year
| Year | Ranking | Degrees C above pre-industrial era |
| 2024 | Hottest | 1.60 |
| 2023 | Second hottest | 1.48 |
| 2025 | Third hottest | 1.47 |
| … | … | |
| 2015 | About the 12th hottest | 0.98 |
The last three years have been the hottest on record since 1880. The Copernicus temperature data and graph clearly show that our planet is heating rapidly.
(See the Copernicus temperature graph for years 1940 to 2025: Copernicus: 14 Jan 2026)
I include the 2015 temperature because it is the hottest year in the following graph.
Global Temperatures are Soaring
.
- Global Air Temperatures from 1880 to 2015
- This is an old temperature graph. In 2016, I thought it showed frightening temperature increases.
- 2015 was the hottest of these years.
- 2014 was the second hottest.
- Now, in 2026, all these temperatures look low because every year since 2015 has been higher, some much higher.
- The black line shows the “long-term trend” of the “average global air temperatures”

The Trump administration has removed or altered a lot of highly informative climate graphs and information from U.S. websites, so I have deleted links to many pages on sites, such as the National Aeronautics and Space Administration (NASA), and the National Snow and Ice Data Centre (NSIDC).
Current temperatures are dangerous
For over a decade, we have been experiencing significant impacts of this warming:
- Hotter weather with extended fire seasons
- Droughts, bushfires and floods are more frequent and intense
- The distribution of plants and animals is shifting towards the poles,
- The planet is losing ice
- The oceans are rising faster
The current temperatures and ongoing increases threaten life as we know it on planet Earth.
