The first results are in ...

America's National Oceanic and Atmospheric Administration (NOAA) has just published the first analyses of global average temperatures for 2010.

Here are the 15 warmest years from 1880 to 2010
(average of global land and sea surface temperature records):
Rank         Year              Difference vs. 20th century average
1=             2005                0.62°C
1=             2010                0.62°C
3               1998                0.60°C
4=             2003                0.58°C
4=             2002                0.58°C
6=             2006                0.56°C
6=             2009                0.56°C
8               2007                0.55°C
9               2004                0.54°C
10             2001                0.52°C
11=           2008                0.48°C
11=           1997                0.48°C
13             1999                0.42°C
14             1995                0.41°C
15             2000                0.39°C
These are all in my daughter's lifetime.  How old is she?  15.

NASA have just released their analysis, confirming the ranking for the warmest 8 years on record (with a slight discrepancy between 7th and 8th place).

The Guardian reports that more analyses of the world's climate in 2010 are due later this month from the Met Office and the World  Meteorological Organisation.

Update:  Here is the Met Office data, with a handy table comparing these three data sets.  Interesting to note the difference in their reporting of temperature anomalies for these years.
