..that CO2 is not a warming gas?

'Each year, human activities release more carbon dioxide into the atmosphere than natural processes can remove, causing the amount of carbon dioxide in the atmosphere to increase.

The global average carbon dioxide set a new record high in 2024: 422.7 parts per million ("ppm" for short).

The increase over 2023 amounts was 3.75 ppm—the largest one-year increase on record.

Atmospheric carbon dioxide is now 50 percent higher than it was before the Industrial Revolution.

The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago.

The ocean has absorbed enough carbon dioxide to lower its pH by 0.1 units, a 30% increase in acidity.'
