The day before yesterday was the end of September, so I made this chart.
I’m sure many people in Tokyo believe the city is getting hotter every year because Japanese citizens often see TV commercials promoting man-made global warming.
However, there has been no warming trend since 1994 for September.
Now including the data for 2020 so far, the capital city of Japan has not experienced a warming trend since the end of the 1990s up to now, neither in spring nor summer.
Even if you look at the autumn data until 2019, there has been no warming trend since 1989.
When November finishes, I will update the autumn chart.
Excellent work in proving that the urban heat island (UHI) theory is actually incorrect. So why aren’t big cities like Tokyo warming like the rest of Japan, is there a case for a reverse theory of UHI? Maybe urban cool island (UCI)? And now that we know big cities are cooler what effect does this have on the temp charts and their averages? Maybe the temp increases, on average, across Japan are much higher? Would love to see some charts on this with all the large cities omitted. Not sure why you left out the official temperature data for all of Japan that shows that overall temperatures are increasing? And any chance you could provide some links to those Japanese TV commercials promoting man-made global warming?
This isn’t a reply to this particular blog/vlog. Just wanted to point out that your Youtube video, Women and Children First, with sniffy slow Joe Biden sniffing the little ladies…was removed from Youtube. Obviously, Alphabet/Google are in on the pedophilia ring.
Freedom is not free. We are watching the destruction of Western, Industrial Civilisation supported by the censorship of Youtube, Twitter, and all mainstream media.
In the Central England Temperature record of 362 years, September is the 111th warmest of that record. It’s getting hot, phew!
A quick regression analysis on the September data show that the trend is not statistically significant.
So I think it’s more accurate to say, “we don’t know what the trend for September in Tokyo has been since 1994 because the data are too noisy.”
If Venus is so hot due to the ‘runaway greenhouse gas effect’ (according to Carl Sagan and cohorts) with an atmosphere that is 95% CO2, how is that concentrated CO2 here on Earth such as found in most fire extinguishers is about 130 degrees below 0 when released from its containment unit?
Are the laws of physics different on Venus than the laws of physics here on Earth? Or is it more likely that the heat is being produced by a much different mechanism?
Natasha, I think the following will be useful in answering some of the questions you pose given your interest in the subject of CO2 and Venus:
Climate Science 3; There is No “Greenhouse Effect” on Venus Either
The video was really interesting to me because it gives all sorts of very interesting data plus amazing photographs from exploratory “landers” on Venus.
Regarding the temperature of CO2 in a fire extinguisher, it is at room temperature when stable and contained. When it is released from the container, it expands adiabatically and so the entropy drops dramatically, hence the low temperature of the gas once rapidly, fully expanded. For a light treatment of this phenomenon, please see https://en.wikipedia.org/wiki/Adiabatic_process#:~:text=An%20adiabatic%20process%20occurs%20without,the%20surroundings%20only%20as%20work.
Refrigeration and “heat engines” work on this principle. A gas is compressed, the heat is taken from it and then the gas is expanded adiabatically resulting in it becoming very cool.
(I find Wikipedia is usually fairly informative on matters that are not as politically driven as is the case with “climate change” where just about everything written there is fiction.)
Natasha, your fire extinguisher analogy is faulty.
Venus with 5% fraction of CO2 would be of similar surface temperature to a first approximation (who knows how its albedo would be affected?). The high surface temperature of Venus is a result of its 93 bar surface pressure. “Heat produced” comes from solar radiation. Heat lost to space, the only cooling mechanism, is radiated to space at the characteristic emissions altitude where atmospheric pressure is about 0.1 bar just as it is in Earth’s atmosphere. Atmospheres on any planet will exhibit a “lapse rate” in temperature profile between the planet’s surface and the characteristic emissions elevation. The dramatic surface temperature difference between Earth and Venus happens simply because of the vast difference in atmospheric density between the two planets. Add sufficient N2, a non-radiative gas, to Earth’s atmosphere and the surface temperature would be similar to that of Venus.
That”s really interressting considering that tokyo as result of it’s growth
in the past 25years(incl. 10% population increase )
should have become a better heat island that it already was.
Considering that the japanese atlantis is now located 30m under water and was inhabited 8000 years ago,
i guess the real global warming and sea level rise happened some time ago.
((though there are still nutjobs with a degree claiming that Yonaguni is not man made(as very symetric shapes in a very limited and defined place are so “natural”),but climate change is.
Welcome aboard, Kirye.
I believe that people in all countries should connect because most people feel the same – which is probably also true when it comes to opinions about climate. Tony Heller and Kirye should connect to James Corbett, thus making it easier for followers searching for truth. Connections like that between Youtubers sharing the same views would probably be positive for that cause.
Scientific thinking is difficult. Take for example the comment about how the non trend in Tokyo must mean there is no UHI effect. It didn’t occur to them that in a cooling local climate, an UHI could result in a reduced or mitigated downward trend, just as easily as it could result in an upward one of it strong enough or the local cooling tend weak enough or non existent. A comparison is required: we need a station out in the countryside near Tokyo, should one exist, to gget a better sense for how strong or weak the UHi effect in Tokyo is. A while back, Tony showed a nice example of this sort of comparison for a couple of stations in Brazil, if I recall correctly.
