Princeton University physicist William Happer is not a fan of models used to predict future manmade global warming, and stars in a new educational video laying out the reasons he believes climate models are faulty.
“And I know they don’t work. They haven’t worked in the past. They don’t work now. And it’s hard to imagine when, if ever, they’ll work in the foreseeable future,” Happer said in a video produced by PragerU.
In the video, Happer argues that even supercomputers used to predict the weather and forecast future global warming aren’t strong enough to capture the complexity of Earth’s atmosphere, including cloud cover and natural ocean cycles.
“That’s why, over the last 30 years, one climate prediction after another — based on computer models — has been wrong,” Happer said in the video. “They’re wrong because even the most powerful computers can’t solve all the equations needed to accurately describe climate.”
Scientists have increasingly been grappling with reconciling the difference between global climate model projections and real-world temperatures. Scientists skeptical of catastrophic manmade warming often point out that models overestimate warming from greenhouse gases.
Cato Institute climate scientists Patrick Michaels and Chip Knappenberger foundthat real-world warming has been on the low end of model predictions for the last six decades, and a more recent study published in the journal Nature Geoscience found a similar trend.
“We haven’t seen that rapid acceleration in warming after 2000 that we see in the models. We haven’t seen that in the observations,” Myles Allen, a geosystem scientist at the University of Oxford, told The Times in 2017.
