Via: Global warming alarmist talking heads like Bill Nye, Neil deGrasse Tyson and Al Gore are constantly paraded around as experts on climate, often claiming that global warming is making weather more extreme and bashing those who “deny” that humans are the main culprit behind this.

So, Fox Business host John Stossel brought in an actual climate scientist to see just how truthful Nye, Tyson and Gore are being when they go on television to sound the alarm on global warming and advocate for phasing out fossil fuels.

“I’ve actually been doing climate science for the last 25 years and these guys haven’t,” Dr. Roy Spencer, a former NASA scientist who’s now a researcher at the University of Alabama in Huntsville, told Stossel.

“Unfortunately, Bill Nye has said some things that are just downright deceptive,” Spencer added. “He’s a mechanical engineer, but he could learn about stuff, and I’m afraid he hasn’t.”

Nye is often brought on by liberal media outlets to talk about global warming, and he often takes to social media whenever a storm occurs somewhere in the world to link it to global warming — despite a lack of evidence that weather has actually gotten more extreme. Nye has also consistently bashed those who are skeptical of man-made global warming, like Spencer, calling them “deniers.”

“I really resent the term, as do other skeptics because we don’t deny climate change — climate change has always occurred,” Spencer said. “Most of us believe that humans have some role in that, but again, this plays well on TV and to certain audiences.”

“Now, Bill Nye can say things like, our recent Tropical Storm Bill — which occurred, by the way, during hurricane season, we do get tropical storms during hurricane season,” Spencer said. “Everything gets blamed on global warming now, even weather events, and it’s just gotten ridiculous and I don’t know how people can say these things with a straight face.”

Nye got lots of media attention for claiming that global warming was causing Tropical Storm Bill in the Gulf of Mexico and wildfires spreading through Alaska. Actual meteorologists, however, bashed Nye for his remarks.

Spencer also criticized Al Gore for claiming that extreme weather events are 100 times more common today than they were in the mid-20th Century — a claim that is patently false. Yet, Gore will not debate skeptics about his global warming claims in the media.

“Which is bullshit,” Spencer remarked when asked about Gore’s weather claim. “Severe weather has not increased. Even the United Nations admits this. That there has not been any measurable increase in severe weather events around the world.”
