Recent Daily Average Mauna Loa CO2

I normally refer to the weekly average readings to discuss new records. The preliminary data suggests that a new record for weekly average data, just shy of 428 ppm, but this is subject to confirmation. The observatory only started posting the preliminary data on Saturdays earlier this year; the final data is published on Sunday. I'll cover it here after confirmation.

I only started tracking daily data, in addition to weekly, monthly and annual data this year. The database goes back to 1975.

There are no values greater than 425 ppm ever recorded since 1975 recorded before 2024.

Forty-three days of 2024 have been higher than 425 ppm, 21 higher than 426 ppm, 9 higher than 427 ppm, and three greater than 428 ppm, the last three days. Yesterday is the highest ever recorded.

If any of this troubles you, don't worry be happy.

To distract yourself from this unpleasantness, I recommend going on your computer and send messages to blogs carrying on about Fukushima. You never know, someone someday might die as a result of radiation exposure from that event. Obviously Fukushima is way more important than all of the world's air pollution deaths, deaths from extreme weather including heat exposure among people who can't afford air conditioning, and all of the world's ecosystems collapsing from fire, flood, heat, bleaching and acidification.

Stands to reason, no?

Have a nice Saturday afternoon and evening.
