Nobel Prize-winning physicist Ivar Giaever resigned as a Fellow from the American Physical Society Tuesday, condemning the group's official stand on global warming. In his resignation note, Giaever wrote: "In the APS, it is ok to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible?" --International Business Times, 15 September 2011
