United Nations World Meteorological Organization (WMO) has reported that 2010 is on track to be one of the three warmest years on record since 1850.
The global combined sea surface and land surface air temperature for January–October is estimated at 0.55 degrees Celsius, plus or minus 0.11 degrees, (0.99 degrees Fahrenheit, plus or minus 0.20 degrees) above the 1961–1990 annual average of 14 degrees Celsius (57.2 degrees Fahrenheit) – at present the highest on record, ahead of 1998’s January-October increase of 0.53 degrees Celsius and that of 2005 at 0.52 degrees Celsius.
The final ranking of 2010 will not become clear until November and December data are analysed in early 2011. According to preliminary operational data from 1-25 November, global temperatures are similar to those of November 2005, indicating that global temperatures for 2010 continue to track near record levels.
