Three academics from Harvard and the University of Potsdam in Germany published a study in the journal Science on Thursday providing evidence that Exxon Mobil, the oil and gas behemoth with a current market capitalization of $466 billion, predicted global warming with incredible accuracy in a series of internal reports and messages starting in the 1970s.
“Specifically, what’s new here is that we put a number on – and paint a picture of – what Exxon knew and when,” said study co-author Geoffrey Supran, who worked as a research associate at Harvard when he did this work.

“We now have airtight, unimpeachable evidence that ExxonMobil accurately predicted global warming years before it turned around and publicly attacked climate science and scientists. Our findings show that ExxonMobil’s public denial of climate science contradicted its own scientists’ data,” Supran told CNBC. “This corroborates and adds statistical precision to the prior conclusions of scholars, journalists, lawyers, and politicians.”
The phrase and hashtag “ExxonKnew” have become a rallying cry after previous reporting from Inside Climate News and others showing that Exxon publicly contradicted its own understanding of climate science.
Exxon Mobil says the “ExxonKnew” movement is a “coordinated campaign” working to “stigmatize” the oil company, “creating the false appearance that ExxonMobil has misrepresented its company research and investor disclosures on climate change to the public.”

It all started with a tweet
The catalyst for the research was a viral tweet, Supran told CNBC.
Stefan Rahmstorf, a physics professor at the University of Potsdam, saw a global warming predictive chart from Exxon Mobil that Supran and Harvard professor Naomi Oreskes had previously discovered, and overlaid actual historical data on top of Exxon’s.
“The overlap was startling,” Supran said and when Rahmstorf blogged and tweeted about it, the results got a lot of attention, “by the standards of climate science on Twitter anyway,” Supran told CNBC.
The three academics then realized that the accuracy of Exxon’s climate’s projections hadn’t been formally studied, and teamed up to write this report. They were surprised to discover is the extent and accuracy of Exxon’s knowledge of climate science.
“It was startling to plot all of the company’s projections onto one graph and find them all line up so tightly around the real-world temperature rise that has ensued since their reports. That gave me pause, seeing quantitatively that Exxon didn’t just know some climate science, they helped advance it,” Supran told CNBC. “They didn’t just vaguely know ‘something’ about global warming decades ago, they knew as much as independent academic and government scientists did. Arguably, they knew all they needed to know.”
According to their research, the academics found that between 63% and 83% of the climate projections Exxon made were accurate in predicting future climate change and global warming. Exxon predicted that climate change would cause global warming of 0.20° ± 0.04 degrees Celsius per decade, which is the same as academic and governmental predictions that came out between 1970 and 2007.
The study in Science builds on work done by investigative journalists at Inside Climate News back in 2015 and Democratic lawmakers at the House Committee on Oversight and Reform, among many others.
Exxon continues to deny its wrongdoing.
“This issue has come up several times in recent years and, in each case, our answer is the same: those who talk about how ‘Exxon Knew’ are wrong in their conclusions,” Todd Spitler, spokesperson for Exxon Mobil, told CNBC.
Spitler pointed to the results of a 2019 case heard before the New York State Supreme Court by Judge Barry Ostrager which did not find the oil and gas company guilty of fraud in its climate change regulation accounting.
“What the evidence at trial revealed is that ExxonMobil executives and employees were uniformly committed to rigorously discharging their duties in the most comprehensive and meticulous manner possible,” Ostrager wrote, and Spitler passed along to CNBC. “The testimony of these witnesses demonstrated that ExxonMobil has a culture of disciplined analysis, planning, accounting, and reporting.”

Thanks to Trump’s repeated executive order attacks on US clean energy policy, nearly $8 billion in investments and 16 new large-scale factories and other projects were cancelled, closed, or downsized in Q1 2025.
The $7.9 billion in investments withdrawn since January are more than three times the total investments cancelled over the previous 30 months, according to nonpartisan policy group E2’s latest Clean Economy Works monthly update.
However, companies continue to invest in the US renewable sector. Businesses in March announced 10 projects worth more than $1.6 billion for new solar, EV, and grid and transmission equipment factories across six states. That includes Tesla’s plan to invest $200 million in a battery factory near Houston that’s expected to create at least 1,500 new jobs. Combined, the projects are expected to create at least 5,000 new permanent jobs if completed.
Michael Timberlake of E2 said, “Clean energy companies still want to invest in America, but uncertainty over Trump administration policies and the future of critical clean energy tax credits are taking a clear toll. If this self-inflicted and unnecessary market uncertainty continues, we’ll almost certainly see more projects paused, more construction halted, and more job opportunities disappear.”
March’s 10 new projects bring the overall number of major clean energy projects tracked by E2 to 390 across 42 states and Puerto Rico. Companies have said they plan to invest more than $133 billion in these projects and hire 122,000 permanent workers.
Since Congress passed federal clean energy tax credits in August 2022, 34 clean energy projects have been cancelled, downsized, or shut down altogether, wiping out more than 15,000 jobs and scrapping $10 billion in planned investment, according to E2 and Atlas Public Policy.
However, in just the first three months of 2025, after Trump started rolling back clean energy policies, 13 projects were scrapped or scaled back, totaling more than $5 billion. That includes Bosch pulling the plug on its $200 million hydrogen fuel cell plant in South Carolina and Freyr Battery canceling its $2.5 billion battery factory in Georgia.
Republican-led districts have reaped the biggest rewards from Biden’s clean energy tax credits, but they’re also taking the biggest hits under Trump. So far, more than $6 billion in projects and over 10,000 jobs have been wiped out in GOP districts alone.
And the stakes are high. Through March, Republican districts have claimed 62% of all clean energy project announcements, 71% of the jobs, and a staggering 83% of the total investment.
A full map and list of announcements can be seen on E2’s website here. E2 says it will incorporate cancellation data in the coming weeks.

Tesla has reportedly delayed the launch of its new “affordable EV,” which is believed to be a stripped-down Model Y, in the United States.
Last year, Tesla CEO Elon Musk made a pivotal decision that altered the automaker’s direction for the next few years.
The CEO canceled Tesla’s plan to build a cheaper new “$25,000 vehicle” on its next-generation “unboxed” vehicle platform to focus solely on the Robotaxi, utilizing the latest technology, and instead, Tesla plans to build more affordable EVs, though more expensive than previously announced, on its existing Model Y platform.
Musk has believed that Tesla is on the verge of solving self-driving technology for the last few years, and because of that, he believes that a $25,000 EV wouldn’t make sense, as self-driving ride-hailing fleets would take over the lower end of the car market.
However, he has been consistently wrong about Tesla solving self-driving, which he first said would happen in 2019.
In the meantime, Tesla’s sales have been decreasing and the automaker had to throttle down production at all its manufacturing facilities.
That’s why, instead of building new, more affordable EVs on new production lines, Musk decided to greenlight new vehicles built on the same production lines as Model 3 and Model Y – increasing the utilization rate of its existing manufacturing lines.
Those vehicles have been described as “stripped-down Model Ys” with fewer features and cheaper materials, which Tesla said would launch in “the first half of 2025.”
Reuters is now reporting that Tesla is seeing a delay of “at least months” in launching the first new “lower-cost Model Y” in the US:
Tesla has promised affordable vehicles beginning in the first half of the year, offering a potential boost to flagging sales. Global production of the lower-cost Model Y, internally codenamed E41, is expected to begin in the United States, the sources said, but it would be at least months later than Tesla’s public plan, they added, offering a range of revised targets from the third quarter to early next year.
Along with the delay, the report also claims that Tesla aims to produce 250,000 units of the new model in the US by 2026. This would match Tesla’s currently reduced production capacity at Gigafactory Texas and Fremont factory.
The report follows other recent reports coming from China that also claimed Tesla’s new “affordable EVs” are “stripped-down Model Ys.”
The Chinese report references the new version of the Model 3 that Tesla launched in Mexico last year. It’s a regular Model 3, but Tesla removed some features, like the second-row screen, ambient lighting strip, and it uses fabric interior material rather than Tesla’s usual vegan leather.
The new Reuters report also said that Tesla planned to follow the stripped-down Model Y with a similar Model 3.
In China, the new vehicle was expected to come in the second half of 2025, and Tesla was waiting to see the impact of the updated Model Y, which launched earlier this year.
Electrek’s Take
These reports lend weight to what we have been saying for a year now: Tesla’s “more affordable EVs” will essentially be stripped-down versions of the Model Y and Model 3.
While they will enable Tesla to utilize its currently underutilized factories more efficiently, they will also cannibalize its existing Model 3 and Y lineup and significantly reduce its already dwindling gross margins.
I think Musk will sell the move as being good in the long term because it will allow Tesla to deploy more vehicles, which will later generate more revenue through the purchase of the “Full Self-Driving” (FSD) package.
However, that has been his argument for years, and it has yet to pan out as FSD still requires driver supervision and likely will for years to come, resulting in an extremely low take-rate for the $8,000 package.
