A live overview of the key indicators of climate change — with open data from NASA, NOAA and NSIDC.
The climate is changing. But what does that mean in concrete terms? This page shows four core figures that scientists worldwide use to track global warming. The data comes directly from NASA and NOAA and is automatically refreshed every six hours.
How to read this dashboard? Each card below shows one indicator: the current value, how much it has changed compared to last year, and a chart showing the trend over time. The higher the line climbs (or in the case of sea ice: drops), the stronger the signal of climate change.
Annual deviation in °C — NASA GISS
Weekly Mauna Loa measurements (ppm) — NOAA GML
Extent in million km² — NSIDC
Satellite measurement (TOPEX/Jason/Sentinel-6) in mm vs. 1993 — NOAA STAR
