摘要
Tree 物種 worldwide face increasing exposure to unprecedented macroclimatic conditions due to anthropogenic 氣候 change, which may trigger biome shifts and ecosystem disruptions. We quantified 氣候 change exposure-shifts to 物種' currently unoccupied 氣候 zones-for 32,089 tree 物種 globally by 2100, assessing both 物種-level and local tree 多樣性 risks. On average, 69% of 物種 are predicted experience macroclimatic shifts in at least 10% of their range, while 14% face exposure in over 50% of their range under a high-emission (4 degrees C warming) future scenario. This suggests that most 物種 retain substantial 氣候 refugia within their current range. However, local tree 多樣性 exposure is predicted to be severe in vast regions, including Eurasia, the northwestern United States and Canada, northern Chile, and the Am
