Kind: research · Impact: medium

## In brief

- A study in Nature Geoscience, published online 10 November 2026, reports that regional contributions to the land carbon flux have become more coupled to interannual atmospheric CO2 fluctuations from 1959 to 2022.
- The paper is identified by doi 10.1038/s41561-026-02136-5.

## Why it matters

It links regional changes in land carbon to year-to-year variation in atmospheric CO2, which bears on how the land carbon sink is understood and monitored.
