NOAA: Fourth Warmest May for Globe

June 17, 2009

The combined average global land and ocean surface temperatures for May 2009 ranked fourth warmest since worldwide records began in 1880, according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C.

The analyses in NCDC’s global reports are based on preliminary data, which are subject to revision. Additional quality control is applied to the data when late reports are received several weeks after the end of the month and as increased scientific methods improve NCDC’s processing algorithms.
