There’s been no warming in Tokyo in decades!

The December-2021 mean temperature data from the Japan Meteorological Agency (JMA) for Tokyo and its Hachijō-jima island in the Pacific are in and so first we look the December trends side-by side:

Data source: JMA

Since 1985, the mean monthly temperature for December in Tokyo has been flat since 1975.

The island of Hachijō-jima, located some 287 kilometers south of Tokyo, thus far away from all the urban sprawl and heat island affects, has also seen a flat mean temperature trend – since 1923!

Nothing unusual is happening at these two very different stations in December.

Annual mean temperatures show no warming!

But that’s only a trend for a month. Now that December data are available, it is possible to update the annual temperature trend for these two stations.

First we plot the JMA mean annual temperature for Tokyo going back to 1994:

Data source: JMA.

Here we see that the megalopolis has been cooling moderately, thus defying the predictions of warming. Despite the sprawling megalopolis of steel, asphalt and concrete, Tokyo has been cooling off.

Obviously there’s something other than trace gas CO2 driving the trends there.

Hachijō-jima

Moving offshore to the Tokyo island of Hachijō-jima, away from all the urban heat island affects, we look at the newest mean annual temperature going back to 1950.

Has it been warming or cooling?

Data source: JMA.

If we look closely at the chart, we see there’s something natural and cyclic behind the temperature at the island in the Philippine Sea, but overall no warming in over 70 years!

    That’s really pathetic. The Japanese will have to try a lot harder to get some Global Warming going. They are letting the rest of us down.

    There are a few places in the world that have slight cooling.

    This helps to show how the United States will change from warming.

    Tokyo is a megalopolis of 37 million. The weather can’t be that bad. The charts show temperatures that are not extreme. Japan must have massive industrial capacity, Hondas and Toyotas can be driven for hundreds of thousands of miles.

    The Japanese know how to fish for tuna, that’s for sure.

    The link is a world map of temperatures on continents and out on the oceans. Wind directions are also on the map. It is -55 degrees F in Siberia these days.

    Christmas Eve early in the am, it was 48 degrees F and it rained for an hour, maybe two, every surface turned into an ice sheet. It seldom rains in late December here on the northern Great Plains.

    Yesterday morning was -17 degrees F. The high for the day, six below zero.

    Risky business to travel, don’t go out of town, stay home.
