Dave Thompson is a respected atmospheric data analyst, not one of the professional disinformers on climate change -- MEM

The prevailing view of 20th century temperature variability is that the Earth warmed from ca. 1910 to 1940, cooled slightly from ca. 1940 to 1970, and warmed markedly from ca. 1970 onward. In this talk I will exploit a physically-based filtering methodology which provides an alternative interpretation of 20th century global-mean temperature variability. The results clarify the consistency between the century-long monotonic rise in greenhouse gases and global-mean temperatures, provide new insights into the climatic impact of volcanic eruptions, and highlight a glaring but previously overlooked error in the time series of global-mean temperatures.
