Summary
- Natural processes, like the movement of zooplankton and other marine organisms, help absorb carbon from the atmosphere
- Concerns are rising as these natural processes are breaking down due to climate change
- Land carbon sinks have temporarily collapsed in 2023, impacting forests, plants, and soil’s ability to absorb carbon
- Reaching net zero emissions is impossible without functioning natural ecosystems

- Total carbon absorption by forests has remained steady but varies by region
- Boreal forests have seen a sharp decline in carbon absorption due to various factors
- Oceans, the largest absorber of CO2, are showing signs of a weakening carbon sink
- Climate models do not account for recent events impacting natural sinks

- Germany, the Czech Republic, Sweden, and Finland have experienced declines in carbon absorption by land due to climate-related issues like bark beetle outbreaks and drought.
- Despite reductions in emissions, Finland’s once huge land sink has vanished.
- Some countries like China and the US are not yet experiencing such declines.
- It is crucial to protect existing carbon sinks by halting deforestation, reducing emissions, and ensuring their health.
