Before last December ended, the UK Meteorological Office was declaring 2022 was the hottest year the nation had experienced since records began (about 150 years ago). My Durham Tees downloads of mean daily temperatures began in December 2008 so I decided to add the station’s data for meteorological years 2000/2001 to 2007/2008. At the risk of causing confusion, I will be giving each ‘met year’ from the beginning of the century to the present just one identifying date with clarification if I introduce calendar years.

(I have checked the difference Decembers make when the annual means of calendar and meteorological years are compared. For the 20 years from 2001 to 2020, the range was 0.28 to -0.52 degrees Centigrade, indicating that some Decembers were more influential than others. After twenty years, the running average difference between Cal and Met is infinitesimal. ).

The Met Office has told us that the ten warmest years have occurred since 2003. Here are the Decembers…

When I first downloaded temperatures from Weather Underground, they were in whole degrees Fahrenheit. It wasn’t until around 2019 that they were suddenly offered to one decimal place, with earlier years revised. I welcomed the increased granularity and it didn’t occur to me to compare the “new” week, month, season and annual averages with the old. It seemed a no-brainer that 365 daily mean temperatures might range from n-0.5 to n+0.49 in a random fashion and the annual average would end up much the same as before. I kept my original pre-Industrial baseline, based on a 10-year daily average in “old” numbers centigrade, minus one degree. Around 2018, the Intergovernmental Panel on Climate Change (IPCC) opined that Global temperature had warmed by this amount since the Industrial Revolution picked up steam. A target was set – to prevent the Global Mean temperature from reaching 1.5° C above pre-Industrial by 2040.
It is common propaganda now that 8 billion human beings are facing a climate crisis and everyone except the elites must get used to making sacrifices if a disaster is to be avoided. (I can’t imagine them living in 15 Minutes Cities.) Well, December temperatures in North Yorkshire have been falling for the last seven years and I thought I should run a check on the ten years of data from December 2008 to November 2018.
Consider a mean temperature of exactly 50° F. Two extreme figures, 49.5 and 50.499, will round up and down to bang on the wholesome 50. My increasingly enfeebled brain tells me that revising 365 days of whole Fs to a more accurate one decimal place should not change the annual average by more than 0.5 degrees Fahrenheit (0.28°C) in a worst-case scenario. Common sense tells me that the annual difference will be much less than this, let’s say plus/minus 0.2°F or 0.11°C.
My December findings…


Instant human-caused Durham Tees warming! Is the Paris target already under threat? It doesn’t matter if this corruption of temperatures has occurred in every weather station around the globe. They are lying to us. Refuse to eat insects.
