State of the Climate

An international, peer-reviewed publication released each summer, the State of the Climate is the authoritative annual summary of the global climate published as a supplement to the Bulletin of the American Meteorological Society.

The report, compiled by NOAA’s Center for Weather and Climate at the National Centers for Environmental Information is based on contributions from scientists from around the world. It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space.

State of the Climate in 2016

This is the twenty-seventh issuance of the annual assessment now known as State of the Climate. Surface temperature and carbon dioxide concentration, two of the more publicly recognized indicators of global-scale climate change, set new highs during 2016, as did several surface and near-surface indicators and essential climate variables. Notably, the increase in CO2 concentration was the largest in the nearly six-decade observational record.
