Central England Temperatures 1659-2016 show no trend

The great trick in chartmanship is choosing your starting and ending points to show the sort of trend you want to show. Warmists do it all the time.  So that is why a really long record is needed -- to avoid showing a small part of the record as typical of the whole.

And the Central England Temperature record is the longest we have -- from 1659-2016.  So what trend does it show?  None at all.  Look particularly at the summer temperatures (in red).  Any global warming should certainly be obvious there.  But it is not.  There IS no global warming and there has been none for a long time

The Warmists are probably nutty enough to claim that England was somehow insulated from the rest of the world but I have no idea  how anyone could explain that.  Extra-terrestrials at work?

What they do say is that the record harks back to the beginning of thermometers so the early readings are not as precisely accurate as modern readings.  What that does however is highlight how tiny and hence how trivial are the changes they deal in:  Tenths and hundredths of one degree.  To changes as small as that, the only reasonable response is "Who cares?"


There has been no change in UK average temperatures in summer(JJA) or in Spring(MAM) for the last 367 years. The two hottest summers were 1826 (17.6C) and 1976(17.8C). I remember 1976 as the perfect summer with two months of continuous sunshine, causing a severe drought.  The two coldest winters were 1740 (-0.73C) and 1963 (-0.07C). 1963 was the perfect time to be a small child aged 10, sledging every weekend. These extremes have not been exceeded for the last 40 years.

UPDATE:  Comment from a reader.

By the way, thermometers have been very accurate since they were invented....why.......well 0 is the freezing point of water and 100 is the boiling point and God will not allow those to be changed. Everything in between is linear. Anyone can make a thermometer. Put some Mercury in a glass tube, seal it. Place it in an ice bath. Mark the glass tube at the top level of the mercury then place it in boiling water(sea level) and mark the glass tube again. Now add graduations linearly the length between the two and WALAA............a thermometer.  The longer the tube of mercury the more accurate and finer reading one can take.
