From NOT A LOT OF PEOPLE KNOW THAT<\/a><\/p>\n\n\n\n

By Paul Homewood<\/p>\n\n\n\n

Last year the Met Office made some changes to the CET record. I did not pay too much attention at the time, as the changes appeared to be minor.<\/p>\n\n\n\n

However, when I was writing my review of 2022, I noticed that whereas the summer of 1995 had been 0.1C warmer than 2018\u2019s in the original Version 1, they had changed places in Version 2. To be precise, the summer of 1995 had been cooled by 0.07C, whilst 2018\u2019s had been warmed by 0.13C.<\/p>\n\n\n\n

I have now got around to analysing the full dataset, and the chart below shows the annual adjustments made:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Positive numbers are where V2 temperatures are higher than V1.<\/p>\n\n\n\n

As you can see, for most of the record up to 1970, the adjustments are small and with no obvious pattern, ups and downs offsetting each other.<\/p>\n\n\n\n

Then quite suddenly the years from 1970 to 2003 have been cooled quite markedly. Then just as abruptly the temperatures have been consistently adjusted up again.<\/p>\n\n\n\n

No doubt the Met Office will gloss over this with some excuse, but unfortunately it is part of a much wider tampering with temperatures globally \u2013 and the tampering is always one way,cooling the past and heating the present.<\/p>\n\n\n\n

Apart from the subtle changes to overall trends, this tampering changes the comparison with recent temperatures and those in the 1970s, 80s and 90\u2019s. The summers of 1995 and 2018 are a classic example. With 1995\u2019s summer cooled by 0.07C, it now only ties with last summer, instead of being hotter.<\/p>\n\n\n\n

And although we don\u2019t have a V1 for last summer, it is safe to assume that V2 temperatures were inflated in a similar way to 2018, which was adjusted upwards by 0.13C.<\/p>\n\n\n\n

This all rather puts the Met Office in a bad light.<\/p>\n","protected":false},"excerpt":{"rendered":"
