Recent decrease of the impact of tropical temperature on the carbon cycle linked to increased precipitation
The atmospheric CO growth rate (CGR) variability is largely controlled by tropical temperature fluctuations. The sensitivity of CGR to tropical temperature has strongly increased since 1960, but here we show that this trend has ceased. Here, we use the long-term CO records from Mauna Loa and the Sou...

The atmospheric CO growth rate (CGR) variability is largely controlled by tropical temperature fluctuations. The sensitivity of CGR to tropical temperature has strongly increased since 1960, but here we show that this trend has ceased.

Our results indicate that wetter conditions have led to a decoupling of the impact of the tropical temperature variation on the carbon cycle.
