TerraUna / Climate data
THE PLANET,
MEASURED.
Explore climate change through historical weather, long-term trends, wildfires and the measurable consequences of a changing planet.
Explore a location
Search a city to explore its historical temperature, precipitation, humidity and wind.
02 / Why TerraUna
CLIMATE CHANGE
IS ABSTRACT.
THE DATA ISN'T.
TerraUna brings historical observations, long-term trends and environmental consequences into the same context, making large-scale climate data easier to read and compare.
01
Observe
Explore historical weather records, global climate indicators and current environmental observations.
02
Compare
Put individual years, locations and events into historical context to see what is changing.
03
Understand
Connect long-term climate trends with measurable consequences such as wildfire activity.
03 / Global temperature
A WARMING
PLANET.
Global surface temperature records show how recent years compare with more than a century of observations.
Global temperature anomaly
Annual mean / 1951–1980 baseline
1880—2025
Global temperature anomaly
Annual global surface-temperature change relative to the 1951–1980 average.
1880–2025
Each value shows how much warmer or cooler the global average temperature was compared with NASA's 1951–1980 average. A value of +1 °C means that year was about 1 °C warmer than the baseline, while negative values indicate cooler years. The annual values show year-to-year variability, while the 5-year average smooths short-term fluctuations and makes the longer-term warming trend easier to see.

Temperature anomalies are used instead of absolute temperatures because they make measurements from different locations and periods easier to compare consistently over time.

05 / The data
BUILT ON
OBSERVATION.
TerraUna does not generate climate measurements. It organizes established scientific and meteorological datasets into a clearer visual context.
01
NASA GISTEMP
Global temperature
Global surface temperature observations used to examine long-term warming trends and annual temperature anomalies.
02
NASA FIRMS
Active fires
Satellite-based near-real-time fire detections used to monitor current wildfire activity around the world.
03
MODIS MCD64A1
Burned area
Satellite-derived burned-area observations used to quantify the amount of land affected by fire over time.
04
Open-Meteo
Local weather
Historical meteorological data used to explore temperature, precipitation, wind, humidity and other conditions by location.
05
GWIS
Wildfire statistics
Global wildfire datasets used for historical burned-area analysis and geographic comparisons.
