Central England Temperature - Warmer and windier
Hilary Benn, the Environment Secretary, is to declare that Britain has warmed significantly in the past 30 years and violent storms are a regular occurrence.
He will unveil a report showing that the annual average temperature in central England has risen by about 1C since the 1970s.
It will also show that 2006 was the warmest year of the past three decades and that average sea surface temperatures around Britain have risen by 0.7C over the same period.
Violent "windstorms" have become more common in the past 20 years, but the level is only as high as it was at the beginning of the last century.
We are lucky that the role of "adjustments" in the record have been comprehensively debated here by a leading "sceptic" and by the expert from the Met Office.
The longer term view was also sent to me thus:

The constant mantra is "increasing incidence of extremes", so I also decided to look at temperature frequency and broke the record into basic bands. You can see these results in the charts as well, including seasonal results and in fact the opposite is true, the range of extreme temperatures has narrowed.
The long temperature improvement from the 19th C is apparent, there is no run away warming, we just don't get the desperately cold years of the past As you noted, the lack of low temperature (Tmin), is driving the situation, rather than any run-away top temperatures. This could well be the result of urbanisation as tarmac etc re-radiates heat at night. The station changes may also be significant latterly.
