The Japan Meteorological Agency (JMA) has released the mean temperature data for April, 2023, for Tokyo and its island in the Pacific: Hachij\u014d-jima.<\/p>\n\n\n\n

April is the big month of spring, and warming would tell us that this month ought to be getting colder due to more CO2 in the atmosphere. But the data doesn\u2019t show that.<\/strong><\/p>\n\n\n\n

Here\u2019s the<\/strong> April mean temperature data for the city of Tokyo since 1988:<\/strong><\/p>\n\n\n\n

<\/a>The April, 2023, mean temperature for Tokyo was a warm 16.3\u00b0C, but the trend for the least 35 years still shows no warming.\u00a0 Data source:\u00a0JMA<\/a>.<\/em><\/p>\n\n\n\n

 Indeed April mean temperatures for the city of Tokyo hasn\u2019t warmed since James Hansen<\/strong> warned of catastrophic global warming before Congress.<\/p>\n\n\n\n

Hachij\u014d-jima<\/strong><\/p>\n\n\n\n

April mean temperatures of Tokyo\u2019s island of Hachij\u014d-jima<\/a>  (located in the Pacific Ocean 287 kilometers south of Tokyo) going back to 1944. The island is rural and free of the urban heat island (UHI) effects.<\/p>\n\n\n\n

<\/a>Data source:\u00a0JMA<\/a>.<\/em><\/p>\n\n\n\n

Here we see that Hachijo-jima\u2019s April mean temperature hasn\u2019t risen in some 80 years! We\u2019ve provided the links so readers can check the data themselves.<\/p>\n\n\n\n

Warming little to do with CO2<\/strong><\/p>\n\n\n\n

If we go back to the time since temperature recording began, it\u2019s true that both locations have warmed. Yet if we compare mean daily of  maximum temperature of (urban) Tokyo\u2019s rate to rural Hachij\u014d-jima, we see a glaring urban heat island (UHI) difference:<\/p>\n\n\n\n

<\/a>Data source: JMA<\/em><\/p>\n\n\n\n

While mean daily maximum temperature in rural Hachijo-jima has risen only very modestly, the rise has been much greater in urban Tokyo, especially over the most recent decades.<\/p>\n\n\n\n
