Globe:
The average global temperature for combined land and ocean surfaces during the December 2003 to February 2004 period (based on preliminary data) was 1.0 degree F (0.6 degrees C) above the 1880-2003 long-term mean, the 3rd warmest December-February on record. The only warmer such three-month period (since reliable instrumental records began in 1880) occurred in 1997-98 and 2001-02. Data collected by NOAA polar orbiting satellites and analyzed for NOAA by the University of Alabama in Huntsville and Remote Sensing Systems in Santa Rosa, Calif., also indicate that temperatures in both the lower and middle troposphere (from the surface to approximately 6 miles above the surface) were warmer than average.
Since 1900, annual global surface temperatures have risen at a rate of 1.0 degree F (0.6 degrees C)/century, with some of the largest increases in the higher latitudes of the Northern Hemisphere. The boreal winter temperature was more than 5 degrees F (3 degrees C) above average throughout much of western and central Asia, as well as parts of Canada. Much of Europe and southern Australia also were warmer than average. Below-average temperatures occurred in northern Australia, where three tropical cyclones made landfall during the austral summer season.
The global ocean surface temperature was the second warmest on record for the three-month period, and temperatures in much of the eastern equatorial Pacific were near average at the end of February as the neutral phase of ENSO (El Niño/Southern Oscillation) continued.
