1Future measurements will refine how R d aggregates to whole-plant respiration.
2For pre-industrial estimates, new baseline R d increases R p and especially in the tropics.
3This allows characterisation of baseline R d, instantaneous temperature responses and longer-term thermal acclimation effects.
4New global datasets describe upper canopy dark respiration ( R d) and temperature dependencies.
5Under global warming, new R d estimates amplify modelled respiration increases, although partially lowered by acclimation.
