越来越多的证据表明，森林干扰正在随着全球变化而发生变化，但干扰的地方差异仍然很大。我们量化了这种相当大的变化，并分析了最近地球仪周围的干扰事件是否始终受到气候的影响，以及人类的影响是否会调节森林干扰的模式。我们将最近（2001-2014年）干扰的遥感数据与温带生物群落中50个受保护景观及其周围环境的深入当地信息相结合。干扰模式是高度可变的，并通过干扰剂和主要树种的特征的变化而形成。然而，高干扰活动始终与地球仪上比平均温度更高和更干燥的条件有关。与受人类土地使用影响的周围环境相比，保护区内的干扰较小，形式也更为复杂。这种信号在最近自然干扰活动频繁的地区消失，强调了气候介导的干扰改变森林景观的潜力。气候变化可能会影响森林干扰，但当地的变异性很大。在这里，Sommerfeld等人表明，整个温带生物群落的干扰模式随因子和树木性状而变化，但大的干扰始终与比平均条件更温暖和干燥有关。
Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability in disturbance remains high. We quantified this considerable variability and analyzed whether recent disturbance episodes around the globe were consistently driven by climate, and if human influence modulates patterns of forest disturbance. We combined remote sensing data on recent (2001–2014) disturbances with in-depth local information for 50 protected landscapes and their surroundings across the temperate biome. Disturbance patterns are highly variable, and shaped by variation in disturbance agents and traits of prevailing tree species. However, high disturbance activity is consistently linked to warmer and drier than average conditions across the globe. Disturbances in protected areas are smaller and more complex in shape compared to their surroundings affected by human land use. This signal disappears in areas with high recent natural disturbance activity, underlining the potential of climate-mediated disturbance to transform forest landscapes. Climate change may impact forest disturbances, though local variability is high. Here, Sommerfeld et al. show that disturbance patterns across the temperate biome vary with agents and tree traits, yet large disturbances are consistently linked to warmer and drier than average conditions.
