The following story from the Met Office/BBC seems to point to a lack of surface weather stations rather then a record warm year, see Surface Temperature Records: Policy Driven Deception written by Anthony Watts & Joe D'Aleo

This year was the second warmest on record for the UK, the Met Office says.
Provisional figures show that only 2006, with an average temperature of 9.73C (49.5F), was warmer than 2011's average temperature of 9.62C (49.3F).
This year saw high temperatures for lengthy periods; including the warmest April and spring on record, the second warmest autumn and the warmest October day.
Early figures suggest 2011 is ending with a "close to average" December.
The Met Office said its figures were a mean temperature taken over day and night.
John Prior, national climate manager at the Met Office, said: "While it may have felt mild for many so far this December, temperatures overall have been close to what we would expect.
"It may be that the stark change from last year, which was the coldest December on record for the UK, has led many to think it has been unseasonably warm."
All bar one of the top 10 warmest years on record have occurred since 1997 and all the UK's top seven warmest years happened in the past decade.
The warmest temperature recorded this year was 33.1C (91.5F) on Monday 27 June at Gravesend in Kent. The Met Office said it was the warmest temperature recorded in the UK for five years.
Apart from January, the other months that had below-average temperatures were June, July and August.
Gravesend was the location for the warmest October temperature ever, when 29.9C (85.8F) was recorded on 1 October, beating the previous record of 29.4C (84.9F) in the Cambridgeshire town of March on the same day in 1985.
The coldest temperature was -13C (8.6F) at Altnaharra in the Scottish Highlands on 8 January, while the strongest gust of wind was 165mph (265.5kph), recorded at the highest point of the Cairngorms mountain range on 8 December.
