Japan’s Own Data Show No Warming For Tokyo…But NASA Tampers, Changes Trend To Warming!

While Japan’s own temperature data show no warming for Tokyo, NASA tampers with the data to make it look like it’s been warming!

Not long ago we looked at the 2021 mean temperature data from the Japan Meteorological Agency (JMA) for Tokyo and its rural Hachij?-jima island in the Pacific. The JMA data for Tokyo show that the megalopolis has in fact been cooling off since 1994.

Today we plot the JMA data, the NASA Unadjusted Version 4 and NASA’s Version 4 Adjusted Homogenized (altered) data for Tokyo on one chart:

NASA manipulated the data until it shows warming. Data sources: JMA, NASA

As the chart above shows, NASA’s Version 4 Unadjusted data plot is very similar to the JMA data, both showing no warming since 1994.


But then NASA altered the data, and now its so-called V4 “Adjusted Homogenized” plot suddenly shows a ruddy warming trend. The JMA data, we suppose, isn’t good enough, and so NASA took it upon themselves to fix it up. Don’t believe the Japanese data!

Hachij?-jima

Next we look at the Tokyo island of Hachij?-jima, some 287 km in the Pacific, and thus isolated from the urban sprawl of concrete, steel and asphalt we have in Tokyo. We look at the mean annual temperatures going back to 1950 from both NASA and the JMA:

Don’t believe the Japanese data, because NASA says it’s not adequately tabulated. Let NASA fix it for you. Warming! Data sources: JMA, NASA.

Once again we see that the story is exactly the same: NASA tampered with the data and now its V4 Adjusted Homogenized data plot shows a strong warming trend since 1950. This is in stark contrast to what the JMA data plot shows and what NASA’s V4 Unadjusted data depict.

It appears NASA takes over good data from other countries, ignores what the country itself tabulated, and then tampers with it until they get the warming trend they want. Then they tell the public the globe is warming everywhere and that the Japanese data are too poorly tabulated to be used.
