Giaever announced
his resignation from APS was due to the group's belief in man-made
global warming fears. Giaever explained in his email to APS: "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? The claim (how can you measure the average temperature of the whole earth for a whole year?) is that the temperature has changed from ~288.0 to ~288.8 degree
Kelvin in about 150 years, which (if true) means to me is that the
temperature has been amazingly stable, and both human health and
happiness have definitely improved in this 'warming' period."
