魁北克一小块地区的三个深井，每个都有两个相隔22年的高精度温度记录，可以可靠地确定过去几个世纪的地表温度历史。温度记录表明，在最近的气候变暖之前，该地区曾在19世纪末附近经历过一段寒冷时期。加拿大其他地区的钻孔温度数据也表明，存在这样一个冷期。
Three deep boreholes in a small area in Quebec, each having two high-accuracy temperature logs separated by 22 years, allow reliable determination of the ground surface temperature history during the past few centuries. The temperature logs show that the recent climatic warming was preceded by a cold period near the end of the 19th century in this area. The presence of such a cold period is also suggested by borehole temperature data from other areas in Canada.
