The UK Met Office long term Central England Temperature record has kept a continuous and consistent data set since the 1660s.  It appears to be reliable and to have maintained its quality.  It has not been adjusted as have so many other official temperature records. 

Although the CET record covers only a small part of the northern hemisphere, it has shown a consistent rise since the end of the little ice age in 1850 at a rate of about +0.45°C / century or about +0.67°C in the last 150 years.  This rise accords well with other temperature records.
However since the year 2000, diminishing solar activity in solar cycle 24, moving back towards little ice age patterns, appears to be having an real effect.
