I just wanted to point out that while it may seem cold for january (from the same Hadley data), we've seen (globally) recent colder Januaries in 2000 and 1996 (how soon we forget).

Here is the plot of the January data from 1900 to 2008. I'm working on one for seasonal winter and I'll post it shortly. Compared to previous years it is a drop but it is still the 30th warmest january on record from 1900 to 2008.

Thanks - in the Johnson Rice graph I linked you can see that we ended 1996 and 2000 winters with about 750bcf left in storage - those were the lows of last 15 years. I just wonder what a bit of reduced production (e.g.5-8%) combined with cold winter might do.

Here is the Winter Temperature Anomaly since 1851 (corresponds to December, January, and February and the year corresponds to the January year value). The winter of 2008 works out as the 19th warmest on record since 1851 (the first complete winter on record).

The dataset from the GISS and NCDC show slightly different values from the Hadley data (but nearly identical trends) based upn how they validate and extend the data.
