Warmer environments significantly limit the efficiency of photosynthetic carbon assimilation because the progressive increase in temperature tilts the balance away from photosynthesis (carboxylation) and toward photorespiration (oxygenation)

Warmer environments have the effect of: Increasing the oxygenase activity of rubisco more than the carboxylase activity.
