I think it means the trees still absorb carbon dioxide. However, it's written in a way that it could also mean the trees are pumping carbon dioxide out. It sounds much more extreme.

as is the current regime of C3 photosynthesis is promiscuous, and involvves O2 photorespiration in some proportion. temperature beyond nominal range will increase the incorporation of O2 and begin 'starving' the plant. what this means is-- trees plants etc lose thier carbon sinking ability beyond a threshold temperature, it is detrimental, and they consume increased quantities of O2 , and have to spend energy to eliminate the product The laboratory conditions that allow us [you included] to observe this phenomenon are no longer an extreme, or a laboratory demonstration.
