The globe experienced the 10th warmest May since record keeping began in 1880, as the climate phenomenon La NiƱa ended its 2011 cycle. The Arctic sea ice extent was the third smallest extent for May on 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.
