Patrick Frank Publishes on Errors Again
Recently I came across yet another paper by Patrick Frank[1] attempting to claim that climate scientists have been underestimating uncertainties in climate-related data. In this paper, he takes aim at GMST data, and he argues that LiG resolution limits, non-linearity, and sensor field calibrations yield GSATA mean ±2σ RMS uncertainties of, 1900–1945, ±1.7 °C; 1946–1980, ±2.1 °C; 1981–2004, ±2.0 °C; and 2005–2010, ±1.6 °C. Finally, the 20th century (1900–1999) GSATA, 0.74 ± 1.94 °C, does not convey any information about rate or magnitude of temperature change. The resulting GMST graph from his calculations is below. Essentially, he's saying that errors associated with liquid in glass thermometers are so large that we can have no confidence in the global warming trend in the major GMST datasets. Of course, the organizations producing these GMST datasets all evaluate the uncertainties associated with their anomaly values, and their estimates are invariably much smaller - about ±0.05°...
