CLIMATEGATE: Jim Lindgren: Michael Mann Should Not Be Investigated By Penn State. “But if I were Professor Mann’s dean at Penn State, I would try to determine whether he has fully shared his data, metadata, and computer code. . . . If Mann is still withholding the data and code necessary for replication, I’d ask him to replicate his most important or most controversial recent work (certainly not everything) and to release the data and code so that others might do so. If Mann couldn’t replicate his own work, I would ask him to announce that fact to the scientific community, so that serious scientists would know whether his work is replicable.” Plus, lessons from the Bellesiles scandal.
