While we know climate change will impact individuals, populations, and communities, we lack a cross-scale synthesis for understanding global variation in climate change impacts and predicting their ecological effects. Studies of latitudinal variation in individuals’ thermal responses have developed primarily in isolation from studies of natural populations’ warming responses. Further, it is unclear whether latitudinal variation in temperature-dependent population responses will manifest into latitudinal patterns in community stability. Integrating across scales, we discuss the key drivers of latitudinal variation in climate change effects, with the goal of identifying key pieces of information necessary to predict warming effects in natural communities. We propose two experimental approaches synthesizing latitudinal variability in climate change impacts across scales of biological organization.

虽然我们知道气候变化会影响个人、人口和社区，但我们缺乏跨尺度的综合来了解气候变化影响的全球变化并预测其生态影响。对个体热反应的纬度变化的研究主要与对自然种群变暖反应的研究相隔离。此外，尚不清楚温度依赖性种群反应的纬度变化是否会体现为群落稳定性的纬度模式。通过跨尺度整合，我们讨论了气候变化影响中纬度变化的关键驱动因素，目的是确定预测自然群落变暖效应所需的关键信息。
