'The Mauno Loa observatory showed the first weekly average CO₂ concentration of 430 ppm in at least 3 million years!'

Atmospheric CO2 has passed 430 parts per million.

The last time CO2 was 430 ppm occurred during the Pliocene Epoch, three to five million years ago. Humans did not exist during this period. The climate news is worse than what we are being told. Trump is doing all he can to usher in the end times.

Land absorbs less

Simons is referring to nature that absorbs the greenhouse gas. Overall, oceans absorb 25 percent of CO2 emissions, land (e.g. forests and grasslands) 25 percent, and 50 percent remains in the atmosphere. But that seems to be changing.

If nature no longer helps us, we have to do it ourselves. More is being done to green energy and to reduce emissions. So why are total emissions not falling? You can see it in this video:

The uptake of trees and plants in particular is lagging behind in the new figures, and emissions are actually increasing. "So that's going completely in the wrong direction," says climate scientist Bart Verheggen of the KNMI. "You hope that emissions will go down, and the uptake by oceans and biosphere will increase along with the concentration. That is not the case."

Yes, it does. Scripps also tracks trace gases, but again, likely some federal funding needed . . . hatrack Wednesday #3

In 2026, we will see multiple months at or above 430 ppm. By 2027. we will never see a monthly reading at or below 430 ppm again.

Oh, fun fact to remember - each ppm is 2.13 billion tons of carbon.

Do you know? Does the Mauna Loa Observatory depend on federal funding?

We'll probably have to use data from the ESA, or Japan's Meteorological Agency.

At least the Japanese don't have to "believe" in the laws of thermodynamics. I take bitter consolation in the thought of the category 5 hurricanes that will be striking red states like Florida and Texas which will be getting.heavy hits at the same time as Trump/Musk gut FEMA. The red states will be getting exactly what they deserve. Maybe I should start learning Japanese.
