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.
When November finishes, I will update the autumn chart.
