State of the Climate in 2014 Report Released

State of the Climate in 2014 Report Cover

In 2014, the most essential indicators of Earth’s changing climate continued to reflect trends of a warming planet, with several markers—such as rising land and ocean temperature, sea levels, and greenhouse gases—setting new records. These key findings and others can be found in the State of the Climate in 2014 report released online by the American Meteorological Society (AMS).

The report, compiled by NOAA’s Center for Weather and Climate at the National Centers for Environmental Information is based on contributions from 413 scientists from 58 countries around the world (highlights, visuals, full report). 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. 

“This report represents data from around the globe, from hundreds of scientists, and gives us a picture of what happened in 2014. The variety of indicators shows us how our climate is changing, not just in temperature but from the depths of the oceans to the outer atmosphere,” said Thomas R. Karl, LHD, Director, NOAA National Centers for Environmental Information.

The report’s climate indicators show patterns, changes, and trends of the global climate system. Examples of the indicators include various types of greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover. The indicators often reflect many thousands of measurements from multiple independent datasets.

The State of the Climate in 2014 is the 25th edition in a peer-reviewed series published annually as a special supplement to the Bulletin of the American Meteorological Society. The journal makes the full report openly available online. The full NOAA press release is also available online.
