Ivar Giaever explains in this video lecture why he rejects global warming alarming. “It’s ridiculous,” he says, to think we can measure global average temperature (GAT) accurately, and that we should consider an increase in GAT from ~1880 to 2015 from ~288 degrees Kelvin to ~288.8 degrees Kelvin (an increase of only 0.3%) frightening. There’s much more in this brilliant lecture.

But who cares what he thinks? He’s just a Nobel Prize-winning physicist. And after all, he’s not a member of the American physical society—because he resigned in protest over the society’s calling the evidence “incontrovertible” that “global warming is occurring” and that “if no mitigating actions are taken, significant disruptions in Earth’s physical and ecological systems, social systems, security and human health are likely to occur.”

 

Listen to the lecture and see if you think “the evidence is incontrovertible.”
