Scientists are worried because they can’t fully explain the big jump, but they think it might mean that carbon absorption by forests, fields and wetlands is slowing down—a major problem for the world.

Levels of carbon dioxide — the most abundant planet-warming gas in the air — jumped up by a record amount in 2024.

Last year was the hottest year on record, the top 10 hottest years were all in the past decade and planet-heating carbon dioxide ... above that level of warming over a longer time period.

Scientists cannot be sure about the composition of the early atmosphere. No measurements can be made, so scientists must analyse indirect evidence from other sources. Type of Evidence What it ...

How will they respond? A patch of old oak trees in the UK is helping scientists to predict how the world’s forests will respond to these higher levels of carbon dioxide as since 2017 scientists ...

Thus, an uptick of carbon dioxide levels ... having a graph on your wrist of the ambient concentration of CO2, and at the very least, it could make a good talking point next time you’re at ...

When carbon inputs and outputs are in balance with one another, there is no net change in SOC levels. When carbon inputs from photosynthesis exceed C losses, SOC levels increase over time.
