陽光、二氧化碳及水份充足情況下，光合作用在樹葉裡頭發生，二氧化碳的碳原子將儲存在樹木裡，並釋出氧氣。484Please respect copyright.ＰＥＮＡＮＡuTiaRqrEqd

秋天時份，溫度驟降，樹木意識到冬天即將來臨，便啟動落葉機制，以免冬天低溫為樹葉帶來傷害。484Please respect copyright.ＰＥＮＡＮＡEp0GtnGaj7

（圖2）根據這個理念，全球氣侯所導致的溫度提升，將會使綠葉時間延長1-3星期。484Please respect copyright.ＰＥＮＡＮＡDxacUUoygS

但出乎意外的是，實驗及現實證據指出，綠葉時間反而是平均縮短了3-6日（Ref1)。484Please respect copyright.ＰＥＮＡＮＡKMuAyRVTlM

（圖3）分析由1948-2015年達434,226項的樹木數據再加上各種實驗，科學家得出以下的解釋。484Please respect copyright.ＰＥＮＡＮＡ82oq8GnkEq

全球變暖再加上大氣二氧化碳含量上升，樹木的光合代謝率亦因而有所提升。484Please respect copyright.ＰＥＮＡＮＡIux2xSjLzs

光合代謝的過程中，二氧化碳的碳原子會以固體方式儲存在榭木內。484Please respect copyright.ＰＥＮＡＮＡ3D0ohpNuRT
如果固體碳原子到達一定的程度，就算溫度和暖，亦會觸發樹葉變黃及落葉發生。484Please respect copyright.ＰＥＮＡＮＡ2a7TehV0Mk

這表示出每一棵樹木均有其轉化二氧化碳至氧氣的限額，並不能夠無窮無盡地吸收二氧化碳。484Please respect copyright.ＰＥＮＡＮＡhbJpfPnm2C
單純依靠種植樹木意圖來改善全球的氣候變化，實際上亦有一定的限制。484Please respect copyright.ＰＥＮＡＮＡjjH27PFzuz
