The Reference Frame did a calculation of temps for central England, from 1659. As you have probably guessed there is no unusual modern warming recorded.
Because the Hadley Center has released the final temperatures in Central England for 2009, I decided to calculate a few things. Although I have also played with the monthly data, this text will be purely about the 1659-2009 annual data. It’s 351 years in total.
The average of the 351 numbers is 9.217 °C. The Pythagorean average of the deviation of the annual data from this average is 0.659 °C. The global warming advocates like to emphasize the warming trend in the last 30 years. How does the warming trend in the last 30 years – and in all other 30-year periods since 1659 – look like in Central England?
Here’s the rest: Warming trends in England from 1659
