Central England Temperature Summer Trends
By Paul Homewood
Further to my recent on post on UK summer temperature trends, Xmetman has produced a graph of CET summer means right back to 1659.

The recent uptick followed by a drop off is evident.
What is astonishing though is that the 10-year running average (in yellow) is no higher now than it was at times in the 18thC, for instance in the 1730’s, and again in the 1770’s and 80’s.
As Xmetman comments:
Nothing exceptional in the way of warming during summers in Central England from 1659, the usual rise and fall as you would expect from a temperature series that is over 350 years in length. There was a surge in summer temperatures around 1990 from 15.5 to around 16.2°C, but that has since fallen back. The linear trend across the whole series is a rise of 0.34°C from 15.14°C in 1659 to 15.48°C in 2015. That equates to a rise of less than 0.1°C per century.
It is worth recalling that, according to the Met Office, there has been greater warming in summer than winter since 1960, and that this is the result of human influence on climate.
