The frost has left the banana looking sad but all the talk is about the warmth of November, the autumn and the year. In this area, November 2011 was the 2nd mildest since before 1900, the autumn (September, October and November) was also the second warmest since 1900. Currently the year 2011 is also the 2nd warmest since 1900! So, what does December need to make it number one. The year to beat is 2006. January and February were actually milder this year than in 2006 by about 1.5 degrees. The spring was much warmer this year by about 3 degrees. However, the summer was much cooler by almost 4 degrees. This autumn was less than a degree cooler than the autumn of 2006; so where does that leave the last month of the year. December 2006 was mild with a mean temperature of 7.7 Celsius. In fact, that made it the 5th mildest December since 1900. For 2011 to be the warmest year since 1900 this month needs to have a mean temperature of 8.6 Celsius. In December 1974 the mean temperature was 8.7 Celsius so the figure is achievable, but this year? No, pretty unlikely, second best again!
