Current status of 2010 global temperatures, from World Meteorological Agency

It's getting down to the proverbial wire as to whether 2010 will be warmer than 1998 (and of course, that depends on what group is doing the analysis, too). But I thought the first paragraph of the WMO's statement about the current state of global temperatures for 2010 worthy of reading:

Cancun/Geneva (WMO) - The year 2010 is almost certain to rank in the top 3 warmest years since the beginning of instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea surface and land surface air temperature for 2010 (January–October) is currently estimated at 0.55°C ± 0.11°C (0.99°F ± 0.20°F) above the 1961–1990 annual average of 14.00°C/57.2°F. At present, 2010’s nominal value is the highest on record, just ahead of 1998 (January-October anomaly +0.53°C) and 2005 (0.52°C). The ERA-Interim reanalysis data are also indicating that January-October 2010 temperatures are near record levels. The final ranking of 2010 will not become clear until November and December data are analysed in early 2011. Preliminary operational data from 1-25 November indicate that global temperatures from November 2010 are similar to those observed in November 2005, indicating that global temperatures for 2010 are continuing to track near record levels.



So, there's only a few weeks left for La Nina to beat back the record. Will it?
