If trees do fail to regenerate, it could further reduce ecosystem carbon storage and amplify the greenhouse effect, the study said.

Predicting ecosystem carbon balance in a warming Arctic: the importance of long - term thermal acclimation potential and inhibitory effects of light on respiration.

We estimate a 30 per cent reduction in gross primary productivity over Europe, which resulted in a strong anomalous net source of carbon dioxide (0.5 Pg C yr - 1) to the atmosphere and reversed the effect of four years of net ecosystem carbon sequestration6.

The report says that tropical forests, peatlands and agriculture should be the priority in ecosystem carbon management.
