Nick is no longer trying to defend USHCN, and is now spreading mindless FUD about it. Perhaps he realizes that my assertions about USHCN adjustments are correct.
USHCN has not been discontinued, the data is updated every single day. Adjusted USHCN is essentially identical to what NCDC is reporting now.
USHCN consists of 1,218 high quality stations. If we look at all 56,434 GHCN stations located in the US, we see a sharp cooling trend.
The frequency of hot days has also plummeted.
USHCN raw data is by far the best long term weather record on Earth. The bottom line is the US is cooling, and NOAA temperature adjustments are fraudulent.
