“When the greening of the Earth was first observed, we thought it wasdue to a warmer, wetter climate and fertilisation as a result of the addedcarbon dioxide in the atmosphere,” Rama Nemani, a co-author of the study, said.

“地球变绿第一次被观察到时，我们一度认为是由于更温暖湿润的气候以及大气中新增二氧化碳带来的肥沃环境”，该研究的共同作者拉玛·奈玛妮说。

“Now, with the medium-resolution imaging spectrometer (MODIS) data,we see that humans are also contributing.”

“现在，有了中分辨率成像光谱仪（MODIS）的数据，我们发现人类也在作出贡献。”
