[Ed. – There’s a serious case being made here, and the site at the link has .gz files with all the relevant temperature observations, for those who can open and use the files. It’s one thing to interpolate a few data points for corrupted or missing information, being careful to conform with the overall temperature trend given the season or time of day. It’s another thing to interpolate “creatively” in those missing-data opportunity slots. But the sheer scope of what’s being done here is an entirely different order of thing. It’s not unfair to call it fakery, when nearly half the data are simply made up, and based improperly on the typical temperature regime of a warmer type of locality.]
The measured US temperature data from USHCN shows that the US is on a long-term cooling trend. But the reported temperatures from NOAA show a strong warming trend. …
The biggest component of this fraud is making up data. Almost half of all reported US temperature data is now fake. They fill in missing rural data with urban data to create the appearance of non-existent US warming.
The depths of this fraud is breathtaking, but completely consistent with the fraudulent profession which has become known as “climate science.”
