Stephen McIntyre

Stephen McIntyre (born c. 1947) is a Canadian mathematician, former minerals prospector, and semi-retired mining consultant who is best known as the founder and editor of Climate Audit, a blog devoted to the analysis and discussion of climate data. He is most prominent as a critic of the temperature record of the past 1000 years and the data quality of NASA's Goddard Institute for Space Studies. He is known in particular for his statistical critique, with economist Ross McKitrick, of the controversial hockey stick graph, which shows a sharp, and arguably unprecedented, increase in late 20th century global temperature.
