HADCET is the Central England Temperature record maintained by the UK Met. The seasonal mean data is available here.
If you graph JJA (June, July and August) the trend is a measly .009C per decade.
The two warmest years are 1976 and 1826. 2011 JJA was 14.8C, below the mean, and 3C colder than 1976.
We were told we were going to fry as “Global Warming” gets going.
