This page monitors the changing climate system and the physical conditions and hazards associated with a warming world.

The Climate monitoring section brings together data on temperature, wildfire activity, CO2 levels and other indicators that help track how the climate is changing and where climate-related hazards are intensifying.

Our datasets combine data from authoritative scientific and international sources with analysis from A greener life, a greener world.

Individual datasets are updated at different frequencies depending on the availability of the underlying data.

Climate monitoring datasets

These are the current datasets we produce with many more to be announced in the coming weeks and months.

European wildfire centre

Track Europe’s wildfire season through current wildfire activity, fire danger, burned area, historical data and archived updates.

Global climate indicators

Track key indicators of the changing climate, including global temperature, temperature anomalies and other measurements of the Earth’s climate system.

Status: In development

Extreme heat

Monitor extreme heat events and temperature anomalies across regions, including the intensity, duration and geographical spread of major heat events.

Status: In development

How our climate monitoring data works

Climate monitoring datasets are updated according to the frequency and availability of their underlying sources. Some datasets provide near-real-time information, while others are updated weekly, monthly or annually.

Where appropriate, we distinguish between:

• Current data — the latest available observations
• Historical data — completed and validated periods
• Archive data — preserved historical snapshots of our live datasets
• Trends and comparisons — longer-term changes and comparisons with historical averages

This approach allows current conditions to be monitored without losing the historical record needed to understand how climate-related conditions are changing over time.

Data sources

Our climate monitoring datasets draw on authoritative scientific and international sources, including European and international agencies, scientific institutions, satellite observations and national monitoring agencies.

Individual datasets identify their specific sources and methodologies.
