Nir Joseph Shaviv (hebräisch ניר יוסף שביב; * 6. Juli 1972 in Ithaca, New York) ist ein israelisch-US-amerikanischer Physiker. Er ist Professor am Racah-Institut für Physik der Hebräischen Universität Jerusalem. Shaviv bestreitet den menschengemachten Klimawandel, ist in verschiedenen Klimaleugnerorganisationen aktiv und gilt als einer der „Stars“ der internationalen Klimaleugnerszene. (de) Nir Joseph Shaviv (Hebrew: ניר יוסף שביב, born July 6, 1972) is an Israeli‐American physics professor. He is professor at the Racah Institute of Physics of the Hebrew University of Jerusalem. He is known for his solar and cosmic-ray hypothesis of climate change which disagrees with the scientific consensus on human-caused climate change. In 2002, Shaviv hypothesised that passages through the Milky Way's spiral arms appear to have been the cause behind the major ice-ages over the past billion years. In his later work, co-authored by Jan Veizer, a low upper limit was placed on the climatic effect of CO2. His best known contribution to the field of astrophysics was to demonstrate that the Eddington luminosity is not a strict limit, namely, that astrophysical objects can be brighter than the Eddington luminosity without blowing themselves apart. This is achieved through the development of a porous atmosphere that allows the radiation to escape while exerting little force on the gas. The theory was correctly used to explain the mass-loss in Eta Carinae's giant eruption, and the evolution of classical nova eruptions. (en) |
