Before we begin, Dr. Roy Spencer just published that Version 6 of the University of Alabama-Huntsville satellite-based global average lower tropospheric temperature (LT) anomaly for June 2021 was -0.01 deg. C, down from the May 2021 value of +0.08 deg. C.
As Dr. Spencer’s chart above shows, temperatures are back within the range seen 20 years ago. The hiatus in global temperature rise appears to have resumed.
June cooling in Tokyo
June’s mean temperature data for Tokyo are now in at the Japan Meteorological Agency (JMA). June has come in at 22.7°C.
Data: JMA.
As the above chart shows, the month of June has been cooling over the past 25 years.
In fact, Tokyo hasn’t seen any warming at all in almost three decades, as the mean annual temperature trend has been downward since 1994, according to the untampered data from the Japan Meteorological Agency (JMA):
Data: JMA.
Next, we look at June mean temperatures for the Tokyo Pacific island of Hachijō-Jima, located about 287 kilometers south of Tokyo – away from all the urban sprawl and heat island effects:

There’s been no warming in 85 years! In fact, the trend is downward since 1976.
Looking at mean annual temperatures at Hachijojima, there’s been no warming in 70 years:

Has the cooling begun? It is time.
This is most probably the maximum turning point if the established cycle is repeating, as it has one thousands times in the proxy record. 2 degs up, then down again, supermiposed on the ice age cycle for 1Ma of records. Nothing anthropoid about it. Puny people have no detectable effect on planetary scale change. Maybe one day. Not yet.
The majority of Australian weather-recording stations are rural. The majority of scaremongering seems to concentrate on the capital cities.
Why is that? The scaremongers would say it’s where most Australians live and are familiar with or, at a stretch, where the best data is from. However, it could well be that the urban heat island effect is as crucial as homogenisation in rendering Australia’s World-class meteorological record suitable for scaremongering.
Even a town of modest size can have a heat island effect. I know from my own experience and recordings that just a few kilometres out of town, our frost likelihood is dramatically different to our nearby town. In part, that’s geography at play, but there is also a significant anthropogenic factor.
When I first discovered the difference, I was gobsmacked. I presumed the maximum minimum thermometer was faulty. I replaced it with another one. Then I placed them side-by-side in a refrigerator and freezer with a regular thermometer and checked the readings. There was no clear fault with either.
We really were that much colder on clear winter nights, so much so that there’s little point explaining it to others locally as the usual response is disbelief. As I said, it is partly due to local geography, which is not obvious at all. This leads to an important question – can the local siting of a recording station influence significantly the data collected? The answer is obviously ‘yes’. Therefore, re-siting (which has happened here in lifetime) can influence it as well.
I know that re-siting the local station just some kilometres onto the lowest portion of my farm would dramatically alter the winter minima recorded locally. If this is possible, it is also possible to go the other way – to shift a station and garner warmer data.
A cynic might say that’s potentially something of a temptation to the ideologically-inclined.
That’s very true. One can see a similar effect when a car is parked next to a house over a cold night. The frost will form on the windows facing away from the house and not on the house side.
It is interesting to note in the charts linked below that long term warming trends are the long run averages of volatile decadal trends that show warming, cooling, and no trend. The implication of this pattern may be that short term variability must be understood as internal climate variability and that therefore that only long term temperature trends have a climate change interpretation.
