报告摘要：
Many future scenarios expect a key role for the land use sector to stabilize temperature rise to 2℃ or less. Changes in land cover can influence the climate system, and the extent and magnitude of the anthropogenic modifications at local and regional scales is still largely unexplored. In this work, we focus on land cover changes (LCCs), use a high-resolution land cover dataset, combine a regional climate model to explore the biophysical effect of LCCs. Around 70 Mha of LCCs occurred in Europe from 1992 to 2015. We find an average temperature change of ？0.12 ± 0.20 °C, with widespread cooling in summer and spring. The mean cooling is mainly correlated with agriculture abandonment (cropland-to-forest transitions), but a new approach based on ridge-regression decomposing the temperature change to the individual land transitions shows opposite responses to cropland losses and gains between western and eastern Europe. The findings may lead to sub-optimal climate change mitigation and adaptation strategies in Europe.
