The globe experienced its seventh warmest July since record keeping began in 1880. July’s Arctic sea ice extent was the smallest on record for that month since records began in 1979. 

The monthly analysis from NOAA’s National Climatic Data Center is part of the suite of climate services NOAA provides government, business and community leaders so they can make informed decisions.

Scientists, researchers and leaders in government and industry use NOAA’s monthly reports to help track trends and other changes in the world's climate. This climate service has a wide range of practical uses, from helping farmers know what and when to plant, to guiding resource managers with critical decisions about water, energy and other vital assets.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.

* Included in this report: NOAA is now making it easier to find information about margins of error associated with its global temperature calculations. NCDC previously displayed this information in certain graphics associated with the report, but it will now publish these ranges in the form of “plus or minus” values associated with each monthly temperature calculation. These values are calculated using techniques published in peer-reviewed scientific literature. More information.
