报告简介:

     The response of terrestrial water availability (and thus aridity and drought) to future climate change is a key concern in the hydrologic and related scientific communities, and for society in general. Assessment of climate model projections using off-line aridity/drought indices has concluded a substantial terrestrial drying trend over global terrestrial environments towards the end of the 21st century. However, this 21st-century drying trend based on aridity/drought indices contradicts direct climate model outputs of increases in runoff and vegetation productivity, suggesting a reduction in future aridity in many regions from hydrological and agricultural perspectives, respectively. Here we show that this contradiction is largely attributed to the ignorance of CO2fertilization effect on vegetation in traditional off-line impact models. Additionally, we offer an effective, physically-based yet relatively simple way to account for vegetation response to elevated CO2in off-line impact models. The new method is then used to re-assess future changes in aridity and drought from multiple perspectives.
