NOAA/USA – How Far Can You Go Back And Get a Negative Trend For January

Over the last few days I have presented data for Arizona, Washington and Utah showing massive cooling trends in January for the last 15 years.  I did something similar for HADCET last month.

So I thought I would do the same “How Far Can You Go Back” for the lower 48 states for January.  I was somewhat surprised. 20 states have a negative trend from 1895 (the beginning of the NOAA data).

Alabama in January (for example) is cooling at -1.9F/Century since 1895. You can check NOAA’s data here if you like. I did, just to make sure.

The top 6 cooling trends:

From 1983 North Dakota -6.919 F/Century
From 1994 Wyoming -4.992
From 1992 Colorado -4.862
From 1990 Nevada -4.704
From 1983 South Dakota -4.613
From 1986 Kansas -3.344
