Increasingly negative tropical water-interannual CO₂ growth rate coupling.

ABSTRACT: Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO₂ emissions in the past six decades¹. Large uncertainties in terrestrial carbon-climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change². Interannual variations in the atmospheric CO₂ growth rate (CGR) are dominated by land-atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon-climate interactions^3-6. It is thought that variations in CGR are largely controlled by temperature^7-10 but there is also evidence for a tight coupling between water availability and CGR¹¹. Here, we use a record of global atmospheric CO₂, terrestrial water st
