We just experienced the hottest year on record...
...again.
How do we know?
Scientists at NASA’s Goddard Institute for Space Studies analyze temperature data from three main sources.
1. Surface temperature measurements from 6.300 weather stations around the world.
2. Ship- and buoy-based observations of sea surface temperatures.
3. Temperature measurements from Antarctic research stations.
This combination of measurements gives us a unique perspective of Earth.
