Earth had 13th warmest March on record

April 14, 2011

The Earth experienced the 13th warmest March since record keeping began in 1880, as the climate phenomenon La Niña continued to be a significant factor. The annual maximum Arctic sea ice extent was reached on March 7 and tied with 2006 as the smallest annual maximum extent since record keeping began in 1979.

Scientists, researchers and leaders in government and industry use NOAA’s monthly analyses 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 monthly analyses of global climate about ranges of uncertainty (“range”) 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.
