One fellow climate blogger recently wrote on how he’s been been looking at GHCN ‘unadjusted’ data and noticed that scientists at NASA appear to have been altering them: “This is a fairly disturbing development,” he wrote.
Heating up Reykjavik and Nuuk
Cited as an example is Reykyavik, Iceland. According to Tony Heller here, “The current version V4 has massively cooled the past, to make it look like Iceland is warming.”
Heller then posted a chart showing the difference between v2 unadjusted and the new v4 ‘unadjusted’ for the Reykjavik station:
Heller also found here that the same appears to be the case for Nuuk, Greenland as well.
With this in mind, we checked the Japanese station Hachijojima, which is situated on a small island in the Pacific well off the coast of Japan. Also here we see that the unadjusted data have been altered, too. The original v3 data depicted by the green curve are compared to the new “unadjusted” v4 data shown by the blue curve:
The new “unadjusted” v4 data have been clearly altered to cool a part of the past and thus enhance the appearance of warming. There appears to be a system behind all the adjustments: Every time the adjustments create more warming.
We also checked over the NASA GISS UHCN data for Syowa, Antarctica:
GHCN V3 Unadjusted: https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show.cgi?id=700895320008&dt=1&ds=7 … GHCN V4 Unadjusted: https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AYM00089532&dt=1&ds=15 …
Also see an animated comparison here. Here as well we see that the data have been altered.
The same is found in Edinburgh, Scotland as well:
Edinburgh(Airport GHCN V3 Unadjusted: https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show.cgi?id=651031600000&ds=7&dt=1 … / GHCN V4 Unadjusted: https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=UKXLT476306&ds=15&dt=1 …
Obviously the history contradicts the global warming theory, and so a group of activist scientists at NASA GISS have taken it upon themselves to rewrite it.
