气候模式模拟的大尺度温度对辐射强迫增加的响应包括增强的陆地-海洋对比度，高纬度地区比热带地区更强的响应，以及温暖和凉爽季节气候对均匀强迫的差异响应。在这里，我们表明，这些模式也是过去的气候模式模拟的特点。陆地与海洋、高纬度与低纬度以及夏季与冬季之间的响应差异在寒冷气候和温暖气候的模拟中非常一致（成比例且接近线性）。类似的模式也出现在历史观测和古气候重建中，这意味着这种响应是气候系统的特征，而不是简单的模型人工制品，从而增加了我们对气候模型正确模拟不同气候状态能力的信心。
Climate‐model simulations of the large‐scale temperature responses to increased radiative forcing include enhanced land‐sea contrast, stronger response at higher latitudes than in the tropics, and differential responses in warm and cool season climates to uniform forcing. Here we show that these patterns are also characteristic of model simulations of past climates. The differences in the responses over land as opposed to over the ocean, between high and low latitudes, and between summer and winter are remarkably consistent (proportional and nearly linear) across simulations of both cold and warm climates. Similar patterns also appear in historical observations and paleoclimatic reconstructions, implying that such responses are characteristic features of the climate system and not simple model artifacts, thereby increasing our confidence in the ability of climate models to correctly simulate different climatic states.
