BAMS State of the Climate

State of the Climate in 2014 Report Cover

Each year, hundreds of scientists from around the world contribute to the State of the Climate report published in the Bulletin of the American Meteorology Society (BAMS). BAMS is the official periodical of the society, devoted to editorials, topical reports to members, articles, professional and membership news, conference announcements, programs and summaries, book reviews, and society activities.

Led by NCEI scientists, the State of the Climate reports provide detailed updates 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.

The reports use dozens of climate indicators to track patterns, changes, and trends in the global climate system, including:

  • greenhouse gases
  • temperatures throughout the atmosphere, ocean, and land
  • cloud cover
  • sea level
  • ocean salinity
  • sea ice extent
  • snow cover

These indicators often reflect many thousands of measurements from multiple independent datasets. The reports also detail cases of unusual and extreme regional events for each year.
