 曲棍球：IPCC在2001年的评估中使用了北半球的平均温度，因为它的形状把它称为“曲棍球棒”。全球变暖怀疑者把这种现象称作中世纪变暖时期（950-1250）和小冰期（1400-1700）和在19世纪过分强调的变暖。从树的年轮、珊瑚、冰芯和历史上的记载获得的时期显示的是蓝色，温度计记录用红色表示，不确定的数据用灰色表示。曲棍球数据因此被相似的温度修复数据证实了（下边）。
Global Warming And Climate Change

HOCKEY STICK A plot of average temperature across the Northern Hemisphere (top) used by IPCC in its 2001 assessment, dubbed the “hockey stick” because of its shape, was decried by global-warming skeptics as hiding the Medieval Warm Period (950–1250) and Little Ice Age (1400–1700) and overemphasizing warming in the late 1900s. Data from tree rings, corals, ice cores, and historical records are shown in blue, and thermometer readings are in red; uncertainties in the data are in gray. The hockey stick data have since been substantiated with similar temperature
