Coda to the Disastrous 2024 CO2 Readings at the Mauna Loa CO2 Observatory: The Worst December Ever Recorded.

For a very long time, I have been following the annual, monthly and weekly readings at the Mauna Loa CO2 Observatory. It turns out that 2024 is the worst year ever recorded in monthly andweekly readings. Herein I will refer to the monthly reading for December 2024 compared to December 2023.

A recent post referring to the horrible weekly readings of mine is here: The Disastrous 2024 CO2 Data Recorded at Mauna Loa: Yet Another Update 12/08/2024

An excerpt.

Most of the time I produce posts in this series, I refer to increases of the 1 year week to week comparators, generally when one of the readings among the 2,550 week to week comparators recorded at the observatory appears in the top fifty. For this week, week 48 of 2024, the increase over week 48 of 2023, the increase is 4.21 ppm higher, which places it as the 20th highest out 2,550 data points of annual week to week comparators going back to the mid 1970's.

It is one of only 34 readings to exceed an increase of 4.00 ppm, thirteen of which took place in the current year. Four of these readings exceed increases of 5.00 ppm, three of which were in 2024. Of the top 50 week to week/year to year comparators 21 have taken place in the last 5 years of which 17 occurred in 2024, 39 in the last 10 years, and 45 in this century.

Of the five readings from the 20th century, four occurred in 1998, when huge stretches of the Malaysian and Indonesian rainforests caught fire when slash and burn fires went out of control. These fires were set deliberately, designed to add palm oil plantations to satisfy the demand for "renewable" biodiesel for German cars and trucks as part of their "renewable energy portfolio." The only other reading from the 20th century to appear in the top 50 occurred in the week beginning August 21, 1988, which was 3.91 ppm higher than the same week of the previous year. For about ten years, until July of 1998, it was the highest reading ever recorded. It is now the 41st highest.

If we focus on the week to week comparators over a ten year period the situation is even more dire.

The increase over week 48 of 2014 is 26.18 ppm.


The monthly reading for December 2024 is here:

December 2024: 425.40 ppm
December 2023: 421.86 ppm
Last updated: Jan 05, 2025

Monthly Average Mauna Loa CO2

The average reading for December 2024 was 3.54 ppm higher than the average in December 2023. It wasn't even close; the second highest increase from year to year December comparators was 3.07 ppm. (December 2014 compared to December 2013.)

The data goes back to 1965. Of all increases from December of a year compared to December of the year before, this is the highest increase ever recorded. The highest increase for any month of any year, as opposed to being limited to a December, was recorded in March 2024 as compared to March of 2023, the 2024 average being 4.38 ppm higher than that of 2023.

The second highest increase for any month of any year was in February of 2024 as compared to February 2023, when the increase in the average was 4.25 ppm higher.

Five of the twelve months of 2024 produced the highest year to year increases for a month, the aforementioned March, 2024; February 2024; July of 2024; November of 2024; and again, December of 2024.

Don't worry; be happy. Listen to all kinds of bullshit about how so called "renewable energy" will save us, and other fossil fuel enabling marketing.

Speaking of fossil fuel marketing, I now return this forum to bullshit from the fossil fuel industry working to rebrand filthy fossil fuels as "hydrogen," a "bait and switch" game which has been described, correctly I think, thus: Hydrogen is Big Oil’s Last Grand Scam

The fossil fuel industry isn't anything if not slick, successfully slick as the Mauna Loa data clearly demonstrates.

...is the world is dominated by unserious people.

Ultimately the question comes down to this: Is one interested in the future of humanity, or is one consumed only with one's own immediate circumstances.

It is an ethical matter. Ethical matters are often the most difficult to resolve, particularly in a world dominated by people who lack any ethical purview.

I have put together a very crude model of a quadratic equation from the data at Mauna Loa which suggests that we will pass 500 ppm around 2046. I'll be dead then, but I expect the survivors will hate my generation for what we did to them.
