Peterson a jeho posledni extempore na poli klimaticke expertizy .]
Peterson said that if the climate was “about everything” then “your models aren’t right” because they couldn’t include everything.
But climate scientists have described Peterson’s comments as “stunningly ignorant” and said he had fundamentally misunderstood the concept of climate modelling.
Dr Sarah Perkins-Kirkpatrick, a climate scientist at the University of New South Wales Canberra, said Peterson’s description of how climate models work was fundamentally wrong. While weather forecasts do become less accurate the further out they go, this was a different process to climate modelling.
“He seems to think we model the future climate the same way we do the weather. He sounds intelligent, but he’s completely wrong.
“He has no frickin’ idea,” she said.

“Anyone who has taken an introductory course in climate or atmospheric science would spot this problem,” he said. “Errors in a weather forecast indeed accumulate such that after a couple of weeks the forecast is useless.”
But with climate, Sherwood said, the models work differently to project how the climate will respond to different factors, such as higher levels of CO2.
“[Peterson’s] argument is like saying we can’t predict whether a pot of water on a flame will boil, because we decide in advance what variables to put in our model, and can’t predict each bubble.”

Peterson’s claim that the climate was too complicated showed “a total lack of understanding of how science works” and could be used to dismiss physics, chemistry, biology, “and every other field of science where one formulates conceptual models”, according to Mann.
“Every great discovery in science – including the physics that allowed Peterson and Rogan to record and broadcast their ridiculous conversation – has arisen through that process,” he said.
“To say that climate model errors increase like compound interest is laughable. Jordan Peterson displays a near complete misunderstanding of climate change, and the tools climate scientists use to understand what is happening to our planet.
“It’s as if someone, with zero expertise and knowledge, made comments about something he knows little about.”
