Eye on Earth tracks the measured state of the planet — from atmospheric carbon and global temperature to clean energy and biodiversity — using open data from the world’s scientific agencies.
A warming world, measured
Every credible scientific record points the same way: the planet is warming, and the fingerprints are everywhere — in the air, the oceans, the ice and the web of life.
The map shows the stylised pattern of surface warming since the pre-industrial era, strongest over the Arctic and the continents.
Below are the headline vital signs, each drawn from an authoritative, openly published source.
Explore by theme
Pick a dimension to dive into the underlying indicators. Each is updated as agencies release new data.
Warmest years (°C vs 1850–1900)
Global electricity mix, 2025 (%)
Change vs baseline
*2025 preliminary. Sources: WMO, Ember, NOAA, WWF, UNEP. Selected indicators, illustrative ordering.
The year the world crossed 1.5°C
2024 was the warmest year ever recorded and the first full calendar year above 1.5°C. Here is what the data shows, and what it means for the years ahead.
Atmospheric CO₂
Past 425 ppm and rising faster.
Renewables overtook coal
A power-mix milestone in 2025.
Record forest loss
Fire the top driver in 2024.
The carbon budget
~4 years left for 1.5°C.
Biodiversity in decline
Populations down 73%.
Material footprint
106 Gt extracted a year.
Three dimensions of change
We group the indicators into three composite pictures — the physical climate, the clean-energy response, and the living environment.
Each spider chart is an illustrative composite index (0–10, higher = more pronounced) built from the indicators in that theme.
The scatter plots every indicator by how its trend is moving against how severe it is.
