Bill Nye: 'You can shoot the messenger but climate is still changing'

The acclaimed scientist and television star talks about his new book and the damaging effects of ignoring the planet’s changing climate

“Excuse me, but gigawatt is pronounced ‘gigg-uh-watts’,” Bill Nye said in 1985. “You say it with a hard ‘g’.”

He was a 32-year-old engineer living in Seattle who called into the live sketch comedy TV show Almost Live! to correct the show’s host, Ross Shafer, who mispronounced the word “gigawatt” while talking about science on-air.
