SUMMARY
This discussion centers on the accuracy of historical temperature measurements from 1880 to the early 20th century, specifically questioning claims of precision to 0.15°C. Participants argue that the limitations of early thermometers, combined with sparse data collection and significant extrapolation, introduce uncertainties that exceed the claimed precision. The conversation highlights the importance of calibration and the averaging of multiple readings to reduce random noise, ultimately suggesting that while historical data may be imprecise, it is supported by various scientific disciplines indicating a warming trend.
