Google is allowing right-wing propaganda organization PragerU to run climate-denying ads on its search engine even though the tech giant previously committed to prohibiting ads that feature claims that contradict the “well-established scientific consensus” about climate change.

In 2021, Google updated its ad policy to prohibit ads for or on content that “contradicts well-established scientific consensus around the existence and causes of climate change.” 

Yet, nearly three years later, Google is still profiting from ads that contain climate change misinformation. 

When Media Matters searched for phrases like “climate change,” “global warming,” and “climate crisis” on Google Search, the search engine returned PragerU ads that promised its website reveals “the truth about climate change” — or what it calls the “fake climate catastrophe.” 

“Climate policies are causing inflation and keeping poor countries trapped in poverty,” the ad-description text read. “Get the facts with our Climate Change and Energy playlist.”

When clicked on, the ads lead Google Search users to a video on PragerU’s website titled “Do We Have to Destroy the Earth to Save It?” In the video, anti-renewable energy activist Michael Shellenberger tells the audience that “pushing the planet toward wind and solar energy would actually cause more harm to the environment than good.” (While all extractive processes have environmental impacts, scientists agree that the consequences of burning fossil fuels on the climate along with the declining costs of both renewable energy and renewable-energy storage make those cleaner technologies essential to a sustainable energy future.)



Shellenberger is known for spreading misinformation about wind energy and downplaying the impacts of climate change. In 2020, Shellenberger wrote an article in which he claimed that “climate change is not making natural disasters worse.” A 2022 report produced by hundreds of the world’s leading climate scientists argued that climate change has increased the intensity — and in some cases the frequency — of extreme weather events. Shellenberger has also defended former President Donald Trump’s unsubstantiated claims that “windmills are causing whales to die in numbers never seen before” and “driving them [whales] crazy.” In 2023, he produced a documentary that alleged — again, without concrete evidence — that “government officials have been lying” about the role offshore wind turbine construction has played in causing whale deaths. 



The video featuring Shellenberger is one of 30 videos on PragerU’s “Get The Truth About The Climate” playlist. 



Other videos on the playlist feature an assortment of well-known climate deniers, including former BP chief scientist Steve Koonin and nuclear energy consultant Patrick Moore, who has repeatedly and falsely claimed that he co-founded Greenpeace. 



In a video titled “Is there really a climate emergency?” Koonin claims that climate change is not settled science, an argument he also detailed in a 2021 book called Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters.



 Another video on the playlist called “The truth about CO2” features Moore, who claims that rising CO2 levels in the Earth’s atmosphere do not present a danger to humans and that “we're already seeing the positive effects of increased carbon dioxide now.” “We should celebrate CO2 as the giver of life that it is,” Moore adds.

PragerU is deeply rooted in climate change denial

Along with the Daily Wire, PragerU is financially dependent on generous donations from fossil fuel billionaire Farris Wilks. 



Recently,  PragerU Kids, a PragerU offshoot that produces conservative “educational” content targeted at school age children, has partnered with five different states to bring right-wing propaganda into public school classrooms. 



Media Matters reviewed PragerU Kids’ ”educational” content and found it was rife with misinformation about climate change. In one video, a cartoon narrator explains why embracing climate denialism is akin to participating in the Warsaw uprising, when Polish Jews attempted to liberate Warsaw from German occupation during WWII.  



Since 2021,  researchers have demonstrated that Google has failed to follow through on its promise to address climate denial. One study found 100 monetized YouTube videos that seemingly violated Google’s climate change misinformation policy. The videos had accrued more than 18 million views. Despite those seeming policy violations, only eight of the hundreds of climate-denying videos studied were eventually demonetized. Google has also profited significantly from ads placed by fossil fuel companies attempting to “greenwash” their reputations as drivers of the climate crisis.
