As I wrote here, Hachijojima where almost a rural area has seen no warming trend for September since 1915.
For the mean annual temperature, the island shows no warming trend since 1948 to 2019.
Looking at the data for autumn, the station has had no warming trend for 45 years.
When I show such data, some climate alarmists get upset. They really love the man-made global warming myth, I know.
