参与耦合模型比对项目第五阶段 (CMIP5) 的最新一代地球系统模型 (ESM) 再现了卫星观测到的地球绿化情况。土地蒸散量 (ET) 预计会随着叶面积指数（LAI，地球绿化）的增加而增加。蒸散的响应在土地-气候相互作用中发挥着关键作用，但之前尚未对其进行评估。在这里，我们评估了 CMIP5 ESM 中外星人对地球绿化的反应。我们验证了 ET 对每个模型中模拟绿化的显着且积极的反应。然而，由于 ET 对 LAI 敏感性的固有偏差，ESM 之间的反应不具有可比性
Satellite-observed Earth's greening has been reproduced by the latest generation of Earth System Models (ESMs) participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5). Land evapotranspiration (ET) is expected to rise with increasing leaf area index (LAI, Earth's greening). The responses of ET play a key role in the land–climate interaction, but they have not been evaluated previously. Here, we assessed the responses of ET to Earth's greening in these CMIP5 ESMs. We verified a significant and positive response of ET to the modeled greening in each model. However, the responses were not comparable across the ESMs because of an inherent bias in the sensitivity of ET to LAI
