I constructed a temperature history for different parts of the world from 169 glacier length records. Using a first-order theory of glacier dynamics, I related changes in glacier length to changes in temperature. The derived temperature histories are fully independent of proxy and instrumental data used in earlier reconstructions. Moderate global warming started in the middle of the 19th century. The reconstructed warming in the first half of the 20th century is 0.5 kelvin. This warming was notably coherent over the globe. The warming signals from glaciers at low and high elevations appear to be very similar.
我根据169条冰川长度记录构建了世界不同地区的温度历史。利用冰川动力学的一阶理论，我将冰川长度的变化与温度变化联系起来。得出的温度历史与早期重建中使用的代理数据和仪器数据完全无关。适度的全球变暖始于19世纪中叶。20世纪上半叶重建的变暖幅度为0.5开尔文。这种变暖在全球范围内显著一致。低海拔和高海拔冰川的变暖信号似乎非常相似。
