State of the Climate
Aug 10, 2017
The 2016 State of the Climate Report was released today from the American Meteorological Society. This is the 27th annual report, which was led by the NOAA National Centers for Environmental Information (formerly NCDC). The report represents the work of nearly 500 scientists from more than 60 countries.
We’ve provided some resources for you to help expand on the report on the air and online and for you to share with your newsroom, as we know they often come to you with questions.
Some highlights of the report are below:
• The 2016 average temperature for the contiguous U.S. was 54.9°F, which was 2.2°F above the 1981-2010 average, this is the second warmest since records began. Since 1970, the rate of warming has increased to 0.5°F per decade.
• 2016 was the globally averaged hottest year on record, surpassing 2015. The record warmth resulted from the combined influence of long-term global warming and a strong El Niño early in the year. Then 10 hottest years on record have all come since 1998.
• Arctic land temperature was 3.6°F above the 1981-2010 average and that region has warmed 6.3°F since 1900.
• Globally averaged sea surface temperatures were the highest on record in 2016. Global sea level was also the highest on record. The rate of warming and the rate of sea level rise in the global oceans are both accelerating.
• The Arctic Ocean is warming dramatically. Parts of the Barents Sea (north of Scandinavia) were as much as 20°F above average in August 2016.
• 2016 was the 37th consecutive year of overall alpine glacier retreat loss across the globe, with an average loss of 2.8 feet. Below the surface (65 feet), record high temperatures were measured at all permafrost observing sites on the North Slope of Alaska.
• Globally averaged carbon dioxide in the atmosphere was 402.9 parts per million, the highest concentration in the history of human civilization. Methane and nitrous oxide, also greenhouse gases, reached record levels.

The World Meteorological Organization's Greenhouse Gas Bulletin is published annually to report on the latest trends in atmospheric concentrations of the most important long-lived greenhouse gases: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

This consensus report, known as the Assessment Report 5 (AR5), is based on a global review of scientific articles that were published or accepted before March 2013 by a team of more than 830 climate scientists from around the world.
