Nobel laureate challenges climate change narrative, highlights overlooked factor.

Nobel ⁢Prize laureate John Clauser has recently been in the spotlight for challenging prevailing climate models, which he says have ignored a key variable.

Mr. Clauser, ‌who recently became a recipient of the 2022 Nobel Prize in Physics for his contributions⁤ to quantum mechanics, holds degrees from Caltech and Columbia University. He served in roles at Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, and ‌the University⁢ of California, Berkeley. In 2010, he was honored with a portion of the Wolf Prize in Physics.

Recently, Mr. Clauser joined another Nobel laureate and over 1,600 professionals in signing the World Climate Declaration (WCD) ⁤organized by Climate Intelligence ‍(CLINTEL). This declaration asserts that there is no “climate emergency,”⁣ that climate change science is not conclusive, and that the earth’s history over thousands of years shows a consistently changing climate.

The WCD ⁣highlights the limitations of ‍current climate models, stating they ‌overemphasize the impact of greenhouse gases like ⁢carbon ​dioxide (CO2). ⁢”In addition, [climate models] ignore the fact that enriching the atmosphere with CO2 is beneficial,” the WCD‍ reads,​ in part.

The declaration further notes that both⁤ natural and human⁣ activities contribute to climate change and the actual warming observed is less than as predicted by the climate⁤ models, revealing our incomplete understanding of climate change.

In an interview with The Epoch Times’s “American Thought Leaders,” Mr. ​Clauser ​voiced his reservations about current climate research quality and contends that U.S. climate policies are misguided.


Prominent climate reports, such as those by the Intergovernmental Panel on Climate ⁣Change (IPCC), National Academy of Sciences, and the Royal Society, emphasize the ⁣role of CO2 but miss the mark on the critical role of clouds in the climate system, according to Mr. Clauser.

His curiosity about clouds began ​as⁤ a ‌sailboat racer. He recalled, “I raced across the ⁤Pacific Ocean at least a dozen times. I had set ⁤up the boat with solar panels to charge the batteries. … I had an ammeter on the power output from the solar⁤ panels, and I noticed ⁤every time we sailed under a cloud, the output from the solar panels ‌dropped by 50 percent to half of its value that it was, and then we came out from behind ⁣the cloud and boom, their power went back up. And⁣ I thought, ‘I ⁤wonder why it’s just about a factor of two.'”

“This is how I became very curious as to how clouds work. When the climate issues came along, I very quickly realized that cloud cover has a profound effect ‍on the earth’s heat input that the clouds are reflecting a ⁤massive amount of light back out into space.

“And so I read all of the various IPCC⁢ reports, National‍ Academy reports on this,” he continued. “As a physicist, I’d worked at some excellent institutions— Caltech, Columbia, Cal Berkeley—where very careful science needed to be done. And reading⁣ these reports, I was appalled at how sloppy the work was. And ⁣in particular, it was very​ obvious, even in the‍ earliest reports, and all carried on through to the present, that clouds were not at all understood. … It’s just ⁤simply bad science.”

Mr. Clauser highlighted insights from former President Barack Obama’s science adviser, Steve Koonin. In Mr. Koonin’s book, “Unsettled:‌ What Climate Science Tells Us, What It Doesn’t, and Why It Matters,” the author noted the inconsistency of the IPCC’s 40 computer models, emphasizing their inability to explain the past century’s climate and suggesting that these ‍models lack‌ a crucial piece of physics.

‘The Missing Piece’

Mr. Clauser said he believes he has identified a ​significant‌ oversight in prevailing climate models.

“I believe I have the missing piece of the puzzle that has been left out in virtually all of these computer programs,” he stated. “And that is the effect of clouds.”

While many theories of anthropogenic climate change focus primarily on the impact of human-produced CO2, ‍Mr. Clauser argues that these models overlook the significance of cloud dynamics.

He referenced the 2003 ‍National Academy report which “totally admitted” its lack of understanding about clouds, adding that the report made “a ‌whole⁤ series of mistaken statements regarding the effects of clouds.”

Drawing attention to ⁢Al Gore’s film, “The Inconvenient Truth,” Mr. Clauser ‍noted, “[Al Gore] insists on talking about a cloud-free earth ‌… That’s a⁢ totally ​artificial Earth.” According ​to Mr. Clauser, this cloudless portrayal of the earth reflects the approach ​taken by⁢ many in the climate science community.

“That’s a totally artificial Earth. It is a totally artificial case for​ using a model, and this is pretty much what the IPCC and others use—a cloud free⁤ earth.”

Emphasizing the real-world dynamics,⁣ Mr. Clauser ‍pointed out that satellite images consistently show wide variances in cloud cover, which can span anywhere from‌ five to ⁣95 percent‍ of the Earth’s surface.

“The cloud cover fraction fluctuates quite dramatically on daily weekly timescales. We call⁢ this weather. You can’t have weather ⁢without having clouds,” ‍he said.

Effect of Clouds Compared to CO2

Clouds play a paramount role in regulating the Earth’s temperature, serving as a “cloud-sunlight-reflectivity thermostat” that ‌”controls ‌the climate, controls the temperature of the earth, and stabilizes it very powerfully and very dramatically,” asserts Mr. Clauser.

With two-thirds of the Earth being oceanic, the ocean becomes instrumental in cloud formation, he said.

Minimal‌ clouds result in ‍heightened sunlight exposure to the ocean, triggering increased evaporation ⁢and subsequent cloud formation, resulting in more clouds. On the contrary, abundant‍ clouds reduce this sunlight, thus curbing evaporation rates and cloud formation, resulting ​in fewer clouds, Mr.⁤ Clauser ⁤explains.

This balance acts like a natural thermostat‌ for the earth’s ‍temperature, ​he said.

Mr. Clauser contends that this “thermostat” mechanism has a vastly greater influence on Earth’s temperature than ⁢the effect of CO2 or methane. He presented to The Epoch Times preliminary calculations that suggest that the​ impact of this cloud-reflectivity mechanism might overshadow CO2’s influence by more than 100 or even 200 times.

All⁣ clouds, irrespective of their altitude or type, reflect almost 90 percent of incoming sunlight, according to⁢ Mr.​ Clauser. The reflectivity fraction, or the average reflectivity of sunlight, is referred to ‍as ⁣albedo. The albedo has been inaccurately kept⁣ constant in various climate models, Mr. Clauser argues.

He finds it baffling how these significant variations, ranging from five to 95 percent cloud cover, have been overlooked.

Mr. Clauser ‍further underscores that clouds are integral to weather dynamics, and yet, current climate models, whose authors “admit upfront⁣ that‌ their ⁣models cannot predict weather,” have been wielded to foretell drastic climatic shifts, including “climate crisis apocalypse.”

The term “climate” refers to long-term, typically 30 years or more, weather condition averages. ⁣While reliable weather forecasts are limited to about a week⁢ with standard weather prediction models,⁤ which take into account the role of clouds, Mr. Clauser points out a paradox in Mr. Koonin’s book: just a 5 percent rise in cloud cover can largely ⁤counterbalance the temperature effect of doubling atmospheric CO2. Despite such nuances, according to Mr.⁣ Clauser, the IPCC’s models​ persistently assume constant albedo, and⁣ bypass the vast cloud⁣ cover variations.

‘Very Dishonest Disinformation’

Mr. Clauser observed that the drive to‌ address human-induced climate change is increasingly shaping political agendas and influencing the⁤ strategic direction of entire nations.

“The whole world is doing all of this. A lot of the pressure is actually coming from Europe, all of these various world conferences”‍ he said, speculating much ⁢of ⁣this push ​might have its roots in Al Gore’s “An Inconvenient Truth,” which he feels has incorporated inaccurate science.

Al Gore’s film ⁤claims that humanity is ⁤triggering a dire climate crisis that necessitates global action. But Mr. Clauser contends: “‘Climate change’ is actually very dishonest disinformation that has been presented by various⁢ politicians.”

He pinpoints a 2013 Physics Today article by Jane Lubchenco and Thomas Karl as pivotal in shaping the narrative, especially during the⁢ period when “g
