Just about all of the media have been peddling the “Hottest for 125,000 years” claim, which suggests a very concerted effort by the climate establishment in the run up to COP28.
The claim is self evident and baseless nonsense for a number of good reasons:
- There is no such thing as “a global average temperature”
- Even now we have very sparse coverage of temperature measurements. Prior to satellites, we had virtually no data outside of the US, Europe and a few other built up areas
- The temperature record we do have is thoroughly corrupted by UHI, and only dates back to the late 19thC
- Natural variations, including ENSO, volcanic activity etc, can easily cause temperature swings of a degree Celsius from year to year, and decade to decade. But historical proxies don’t have the fine resolution to pick these up, they merely give an idea of average temperatures over decades and even centuries. Consequently you cannot compare one year now with the general climate of, say, 2000 years ago.
But forget about all of these theoretical objections, because the climatic evidence we do have is overwhelming, and it tells us that the climate has been much warmer than now for most of the last 10000 years, since the end of the ice age.
Here are ten powerful, incontrovertible pieces of evidence:
1) Greenland
