(Giaever, former professor with Rensselaer Polytechnic Institute and winner of the Nobel prize in physics in 1973, resigned from the APS due to the stated policy of the APS that "global warming is occurring"; APS has taken the position that "the evidence is incontrovertible" that global warming is occurring, but Giaever noted that global temperature has increased only 0.8 degrees Kelvin over the past 150 years with the result that "human health and happiness have definitely improved in this 'warming period'"; Giaver noted that the use of the word "incontrovertible" by APS is contrary to the very nature of scientific inquiry).
