About ClimateDataHub

ClimateDataHub presents key climate change indicators in an accessible format — global temperature records, atmospheric CO2 levels, country-level emissions data, and extreme weather event tracking.

What You Will Find

The global temperature page charts the NASA GISS temperature anomaly from 1880 to 2024 in degrees Celsius relative to the 1951-1980 average. The CO2 page shows the NOAA Mauna Loa annual average in parts per million since 1960. Country pages compare per-capita CO2 emissions, temperature change and sea level rise for 12 countries.

All figures are static snapshots of published datasets rather than live feeds, so the latest year shown is the most recent value built into the site. Full attribution is on the data sources page.
