Twelve measurements of the planet’s health, from the gases in the air to the ice in the Arctic, drawn straight from NOAA, Copernicus, the US National Snow and Ice Data Center and Our World in Data. Each one is explained, charted and downloadable.
Carbon dioxide, methane, nitrous oxide and sea level reload live from NOAA when you open this page. Everything else was last checked on .
Each tile shows the latest measurement, when it was taken and how it compares with the past. The coloured label is worked out from the data itself:
Different datasets update at different speeds: daily for temperature and sea ice, monthly for greenhouse gases, yearly for energy. Each tile says exactly how up to date it is.
| Indicator | Source | Updates |
|---|---|---|
| CO₂, methane, nitrous oxide | NOAA Global Monitoring Laboratory | Monthly, live |
| Air and sea surface temperature | Copernicus Climate Pulse (ERA5) | Daily |
| El Niño index | NOAA Climate Prediction Center | Monthly |
| Arctic sea ice | NSIDC Sea Ice Index | Daily |
| Sea level | NOAA Laboratory for Satellite Altimetry | Irregular, live |
| Ocean heat | NOAA NCEI, via Our World in Data | Yearly |
| Emissions, fossil fuels, electricity | Global Carbon Budget, Energy Institute and Ember, via Our World in Data | Yearly |
Altimetry data are provided by NOAA Laboratory for Satellite Altimetry. Temperature data contain modified Copernicus Climate Change Service information.
