Taking Earth's pulse: The Global Climate Indicators

Learn more about the seven Global Climate Indicators here.

​The vision of Global Climate Observing System (GCOS) is for all users to have access to the climate observations, data records and information they need to address pressing climate-related concerns. GCOS users include individuals, national and international organizations, institutions and agencies. GCOS works with partners to ensure the sustained provision of reliable physical, chemical and biological observations and data records for the total climate system – across the atmospheric, oceanic and terrestrial domains, including hydrological and carbon cycles and the cryosphere.

GCOS specifies 54 Essential Climate Variables (ECVs) that are key for sustainable climate observations.

Measurements of air temperature, a GCOS ECV, provided by the Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts  (ECMWF).
