What this section covers
Earth Data tracks the fundamental physical signals of a changing planet: greenhouse-gas concentrations, surface temperature, sea level, ocean heat and ice.
Each indicator is drawn from authoritative, openly published records and updated as new data is released.
These are the slow, reliable measurements that reveal the underlying trend beneath year-to-year weather.
