GHCN V3 Unadjusted Data Shows Lungi, Sierra Leone Had A Cooling Trend Since 1880

What follows is the data from Lungi, Sierra Leone.

GHCN V3 Unadjusted data shows the station had a cooling trend of about -0.9C from 1880 to 1996, while V4 Unadjusted data shows a cooling trend of -0.7C.
Looking at the same period with the GHCN V4 adj ? homogenized data, the station shows a cooling trend of -0.3C.

For some strange reason, the V3 Unadjusted data has data on the mean annual temperatures up to 1996, but the V4 data has data up to 2018.
GHCN V4 Unadjusted data shows the station had an upward trend of less than 0.1C from 1880 to 2018, while V4 Unadjusted data shows a warming trend of about 1C.

Climate alarmists use the word ?science? to describe such a major data change.
