NOAA shows US December temperatures increasing at 0.1F per decade since 1930.
They are actually decreasing at 0.1F per decade since 1930.
In order to make Zeke happy, I used only a stable set of stations which haven’t changed latitude since 1930.
The NCDC adjustments are quite cynically linear, and create a non-existent warming trend, where cooling has occurred.
Temperature graphs from NOAA and NASA are meaningless propaganda, intended to bring money in rather than inform the public. NOAA employees stand to make huge amounts of money by whistleblowing fraud. Contact Kent Clizbe for details.
