植物的光合作用也存在对高CO2浓度的适应，不会一直维持较高的光合水平，而且植物的呼吸作用也可能会增加；
Plant photosynthesis can acclimate to the elevated CO2 and not keep a higher rate throughout the whole season. The plant respiration may be increased by the elevated CO2.
大部分植物是碳3植物，在高温干旱条件下，由于光呼吸作用而使碳水化合物的合成降低。
Most plants are C3 plants; they experience decreased carbohydrate production under hot, dry conditions as a result of the effects of photorespiration.
