Quoting Obama's warning that "no challenge poses a greater threat to future generations than climate change," Dr. Ivar Giaever said it was a "ridiculous statement."
"I say this to Obama: Excuse me, Mr. President, but you're wrong. Dead wrong," he said, according to Climate Depot.
And I would add, the Pope is wrong too.
Giaever was one of more than 100 co-signers in a letter to the president in March 2009 that was critical of his stance on global warming, saying, "We the undersigned scientists, maintain that the case for alarm regarding climate change is grossly overstated."
