Steve McIntyre (born 1941) is a Canadian statistician and mining analyst known for his critical analysis of statistical methods in climate science. He gained prominence for questioning the validity of the 'Hockey Stick Curve,' a key piece of evidence for 20th-century global warming. Collaborating with economist Ross McKitrick, he reanalyzed data from Michael Mann et al., highlighting statistical flaws and data selection issues. His work sparked debates on methodology and transparency in climate research. Although not a climate scientist, his contributions emphasized the importance of reproducibility and rigorous statistical review. McIntyre's efforts have influenced discussions on scientific integrity and data sharing in climate studies.
