Tokyo has seen its coolest September in over 30 years, according to data from the Japan Meteorological Agency (JMA).
Data source: JMA.
Tokyo’s mean temperature for September, 2021, was 22.3°C — the coolest recorded September mean in over 30 years.
Hachijojima island
Meanwhile, Hachijojima, an island belonging to Tokyo out in the Pacific and absent of the urban heat island effect, saw a September mean temperature of 24.5°C:
Data source: JMA.
Plotting the data going back 107 years, the island has not seen any real warming at all in September.
Osaka
The industrial city of Osaka saw a September mean temperature of 24.6°C:
Data source: JMA.
Osaka has seen September mean temperatures cooling modestly since 1994.
Latest ENSO forecast: La Niña!
Globally, the mean temperature over the coming year will likely see more cooling as La Niña conditions are forecast until mid spring 2022, the latest NOAA NWS projections show:

Global warming alarmists will have to settle for chasing around the globe, looking for thunderstorms — calling them “supercells” — and using them as bogus signs of climate change. But everyone knows extreme weather is part of our planet and have been around for millions of years. It’s nothing new.
Nothing that unusual is happening to our climate. Claims of increasingly extreme weather due to mankind’s activities are largely false. The data clearly show it.

Folks I posted this several days ago and got no response & so I’ll try again …. any leads would be appreciated!
re the CO2 is not a great driver of climate – I got Steve Koonin’s Unsettled and I think his review & treatment of CO2 is appalling.
Has anyone seen a review of this portion of his book pointing out his errors and oversites regarding CO2.
I would rate the book fair except for the CO2 section which seems about 1/10 of what it should be and very uncritical.
Thanks folks.
Could you be more specific on what Koonin says
that you disagree with?
In the 4.5 billion year history of our planet,
the only known periods of time when CO2 level growth
and the global average temperature had a strong
positive correlation were,
when temperature changes
did not lead CO2 changes,
were:
1975 to 2003 (28 years)
and
mid-2015 through 2020 (5.5 years)
That adds up to 33.5 years out of 4.5 billion years.
That’s not even close to enough evidence
to claim that CO2 is the climate “control knob”

“… calling them ‘supercells’…”
Cripes, do these clowns know anything? Or even bother to learn anything?
Thunderstorm formation requires the presence of three ingredients – moisture, instability, and lift; the last can be provided by convection caused by instability, and/or by mechanical lift (such as that induced by an advancing cold front). The formation of *severe* thunderstorms requires the presence of a fourth ingredient – wind shear.
When the wind shear that is present is bulk shear (wind with altitude all flows in the same direction, but with higher speeds aloft), the thunderstorms that are produced form along a line – what is known as a Quasi-Linear Convective System (QLCS), which is colloquially-known as a squall line. The main threat of a QLCS is strong straight-line winds, particularly if conditions cause the shape of the line to bow.
When the wind shear that is present is differential shear (wind changes direction – greatly – with altitude), the differential shear induces helically-rotating structures parallel to the surface; if these helical structures are “ingested” by a developing thunderstorm, the convective updrafts will tip that helix upward – and the thunderstorm cell will rotate around itself. This rotation causes these thunderstorms to be single-cell (not like the QLCS), and they can become very large. THIS is what a “supercell” thunderstorm is. Supercell thunderstorms are the producers of nearly all tornadoes (for obvious reasons if you think about it a little), as well as producing nearly all of the enormous hailstones that occur.

Temperature change on islands are the best indicators for the overall temperature of Earth’s atmosphere, since they represent the temperature of the air over the ocean, hence the temperature of the ocean surface as well as of 2/3 of the atmosphere’s total air mass.
What Kirye found about Hachijojima island’s climate change (lack thereof, actually) is one of the most powerful pieces of evidence to show that Earth’s climate has not warmed during this period, and that the increase in temperatures measured over land is due mainly to the effect of urbanization, deforestation, etc.
