The HADCET dataset is the longest instrumental record of temperature in the world.

One of the minor problems with HADCET is they calculate anomalies from the 1961-1990 average.

This is HADCET (March Only) with anomalies calculated from the most recent 30 years average: 1981 to 2010.

HADCET cooling 1998 – 2012 Winter, Spring and Fall

HADCET is the Central England Temperature record maintained by the UK Met. The seasonal mean data is available here.

I have graphed the data for the last 15 years.

DJF (Winter) is cooling at -1.314C / decade.

MAM (Spring) is cooling at -0.064C / decade

JJA (Summer) is cooling at -0.4C / decade

 

HADCET June July and August trend for 350 years is a measly .009C per decade

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.
