February Ranked 17th Warmest on Record

March 15, 2011

This year, the globe experienced the 17th warmest February since record keeping began in 1880, as the climate phenomenon La Niña continued to be a significant factor. Last month’s average Arctic sea ice extent tied with 2005 as the smallest extent for February in its 32-year period of record.

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. Visit us on Facebook.

* Included in this report: Based on requests from our users, NOAA is now making it easier to find information in its global State of the Climate report 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.
