Gordon James Fraser MacDonald (July 30, 1929 - May 14, 2002) was an American geophysicist and environmental scientist, best known for his principled skepticism regarding continental drift

) causes for global climate change. While often on what would turn out to be the "wrong" side of scientific issues, MacDonald was admired for his creative mind, and his ability to connect scientific issues and matters of public policy.

MacDonald was born in Mexico of a Scottish father and American mother. A childhood bout with polio only sharpened his competitive instincts. He applied to Harvard for a football scholarship and graduated summa cum laude at the age of 20. Remaining at Harvard, he became a Harvard Junior Fellow

, then received his Ph.D. in geology in 1954. MacDonald was a faculty member at MIT (1954–1958), UCLA (1958–1966), UC Santa Barbara (1968–1970), Dartmouth (1972–1983) and UCSD (1990–1996).

Outside of academia, MacDonald served on the original Presidential Council on Environmental Quality (1970–1972). President Nixon remarked at the time, "I have three members of the Harvard class of 1950 on my staff, all summa cum laude." The reference was to Henry Kissinger

MacDonald's interest in climate change was an outgrowth of his work on weather modification

That panel's conclusion, that weather modification was possible, was immediately attacked on statistical grounds. An article in the Journal of the American Statistical Association (June, 1967) concluded, "That such nonsense should appear under the aegis of the National Academy of Sciences is deplorable."
