A warmer and wetter world would aggravate GHG emissions intensity in China’s cropland.xlsx

Global climate models (GCMs) and observations indicate that convective precipitation would be enhanced in a warmer world, with dry regions becoming drier and wet areas becoming wetter. In this dataset, we used an improved agricultural ecosystem model (DLEM-AG2.0), to quantify the impacts of the drier-warmer (<em>DW</em>) climate and the wetter-warmer (<em>WW</em>) climate on crop yield and soil greenhouse gas (GHG) emissions in China. The results show changes of crop yield, GHG emission, N₂O emission, CH₄ emission and GHG intensity induced by all environmental factors, climate change (<em>WW</em> and <em>DW</em>), and N fertilizer coupling with climate change (<em>WW</em> and <em>DW</em>) from 1961 to 2099. The results also show the impacts of extreme drought (<em>ED</em>), slight drought (<em>LD</em>), slight wet (<em>LW</em>), and extreme wet (<em>EW</em>) with extreme heat relative to the normal climate. <br> <br>
