...year for carbon dioxide emissions until 2016.
I often refer to this in my updates on the collapse of the planetary atmosphere, most recently, two weeks ago here:
New Weekly CO2 Concentration Record Set at the Mauna Loa Observatory, 431.73 ppm
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 2,617 week to week comparators recorded at the observatory appears in the top fifty. For this week, week 18 of 2025, the increase over week 18 of 2024, the increase is 3.96 ppm higher, which places it as the 15th highest out of these 2617 points of annual week to week comparators going back to the mid 1970's.
The current reading is the 9th reading to exceed 430 ppm, seven of which happened last year, out of 2617 week to week comparators going back to the opening of the observatory in the second half of the 1970s.
It is one of only 38 readings to exceed an increase of 4.00 ppm, the first to 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 27 have taken place in the last 5 years of which 13 occurred in 2024, 3 in 2025, 38 in the last 10 years, and 46 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." This case represents just one of the many cases demonstrating the unacceptable profile of so called “renewable energy” with respect to land use. 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 47th highest.
Palm oil as energy is an environmentally odious idea. It should have been a warning way back in 1998 that so called "renewable energy" is not sustainable, nor is it clean.
