We are told climate change is a crisis, and that there is an "overwhelming scientific consensus."

"It's a manufactured consensus," says climate scientist Judith Curry in my new video. She says scientists have an incentive to exaggerate risk to pursue "fame and fortune."

She knows about that because she once spread alarm about climate change.

Media loved her when she published a study that seemed to show a dramatic increase in hurricane intensity.

"We found that the percent of Category 4 and 5 hurricanes had doubled," says Curry. "This was picked up by the media," and then climate alarmists realized, "Oh, here is the way to do it. Tie extreme weather events to global warming!"
