Scientists Warn 'Garbage' Models Underestimate Risk of Economic Collapse From Climate Crisis
Current models "assume the future will behave like the past, even as we push the climate system into uncharted territory," said the lead author of a new report that's based on input from dozens of experts.
Feb 05, 2026
In a report published Thursday, UK experts highlighted the "growing gap between real-world climate risk and the economic analysis used to guide policy, supervision, and investment," while also warning that because the "window for preventing catastrophic warming" is narrowing, ambitious action "cannot await perfected models."
Various scientific institutions concur that 2025 was among the hottest years on record—and the ongoing failure of governments across the globe, particularly the Trump administration, to enact policies that would significantly cut planet-heating emissions from fossil fuels is pushing the Paris Agreement's 1.5°C and 2°C goals for this century further out of reach.
The new report from the University of Exeter and the think tank Carbon Tracker Initiative, titled Recalibrating Climate Risk, incorporates the expert opinions of 68 climate scientists from Australia, Austria, Canada, China, France, Germany, the Netherlands, Norway, Spain, Sweden, the United Kingdom, and the United States.
"Our expert elicitation reveals a fundamental disconnect: Climate scientists understand that beyond 2°C, we're not dealing with manageable economic adjustments," said Jesse Abrams, lead author and senior impact fellow at Exeter's Green Futures Solutions, in a statement.
"The climate scientists we surveyed were unambiguous," he explained. "Current economic models systematically underestimate climate damages because they can't capture what matters most—the cascading failures, threshold effects, and compounding shocks that define climate risk in a warmer world and could undermine the very foundations of economic growth."
Abrams said that "for financial institutions and policymakers relying on these models, this isn't a technical problem—it's a fundamental misreading of the risks we face, which current models miss entirely because they assume the future will behave like the past, even as we push the climate system into uncharted territory."

Communities around the world are already contending with devastating droughts, fires, and storms—and, as another report from researchers at Exeter and the UK's Institute and Faculty of Actuaries (IFOA) pointed out last month, "above 1.5°C, we enter the danger zone where multiple climate tipping points may be triggered, such as the collapse of ice sheets in Greenland and Antarctica, permafrost melt, Amazon dieback, and changes in ocean circulation."
The IFOA report "warned that when cascading and systemic risks are taken into account, warming of 2°C by 2050 could result in a 25% hit to projected GDP, rising to a halving of projected economic growth between 2070 and 2090," BusinessGreen editor-in-chief James Murray reported Thursday. "Similarly, a report from consultancy Boston Consulting Group calculated a third of the global economic output could be lost under a scenario where temperatures reach 3°C above preindustrial levels by 2100."
"The studies stand in stark contrast to some mainstream economic models that have suggested warming of 2°C or more will only reduce projected economic growth by a few percentage points—analyses that have been seized upon by opponents of climate action to argue that decarbonization policies can be dropped or delayed," Murray noted.
Abrams told the Guardian that some current economic models "are saying we'll have a 10% GDP loss at between 3°C and 4°C, but the physical climate scientists are saying the economy and society will cease to function as we know it. That's a big mismatch."
Your periodic reminder that the economic models that suggest climate change will knock a couple of percent of future GDP - models that are used widely by governments, investors, and businesses - are almost certainly complete garbage. www.businessgreen.com/news/4525211...

Laurie Laybourn, a Carbon Tracker board member and executive director of Strategic Climate Risks Initiative, cited another recent report that provides a bleak picture of the current moment and what lies ahead.
"As the UK government's landmark security assessment of ecosystem collapse showed last week, we are currently living through a paradigm shift in the speed, scale, and severity of risks driven by the climate-nature crisis," she said. "Yet, beyond this report, there has not been a corresponding paradigm shift in how regulators and government as a whole assess these risks."
"Instead, they're routinely underestimated if not missed entirely, meaning many regulations and government action are dangerously out of touch with reality," she continued. "This threatens disaster when that reality catches up with us. So, it's critical that policymakers change course, providing clear signals and guidance to markets that these risks should be priced accordingly, rather than downplayed."
And, as the experts emphasized Thursday, it's not just policymakers—investors are also still relying on "flawed economic advice," said Carbon Tracker founder and CEO Mark Campanale. The result is "widespread complacency... with many investors viewing climate scenario analysis as a tick-box disclosure exercise."
"Until the gap between scientists and economists' expectations of future climate damages is closed and government bodies act to ensure the integrity of advice upon which investment decisions are made," he added, "financial institutions will continue to chronically underprice climate risks—meaning that pension funds and taxpayers will remain dangerously exposed."
Hetal Patel, head of sustainable investment research at Phoenix Group, the UK's largest and retirement and savings business, said that her firm "supports the report's call for a more robust and coordinated approach to climate‑risk modeling. Underestimating physical risk doesn't just distort financial analysis and investment decisions, it underplays the real‑world consequences that will ultimately affect customer outcomes and society as a whole."
The new report stresses that addressing the "fundamental disconnect between what climate scientists understand about climate impacts and how these impacts are represented in economic models" would require "research investments spanning years," but rather than simply waiting for better modeling, decision-makers "must proceed on the basis of precautionary risk management, physical climate science, and observed impacts."

Dr. Oz: Goal of Trump Healthcare Plan Is to Get Americans to ‘Work One More Year' in Their Lifetime
"I'm sure everyone would be happy to work another year if work meant getting paid millions of dollars to spout utter nonsense," responded one critic.
Jan 21, 2026
Medicare and Medicaid Administrator Mehmet Oz on Wednesday said that one of the ultimate goals of President Donald Trump's healthcare plan is to get Americans healthy enough so that they're able to work for at least one more year during their lives.
During an interview on Fox Business to tout Trump's recently unveiled and widely derided healthcare plan, Oz explained why it was important for Americans to be healthy so that they could be productive workers and contribute to US gross domestic product (GDP).
"A lot of people watching this segment are thinking we're talking about healthcare expenses," he said. "This is about the value to the US economy if we can get this right. If we can get the average person watching... to work one more year in their whole lifetime, just stay in your workplace for one more year, that is worth about $3 trillion to the US GDP."
"Wow!" exclaimed Fox Business host Maria Bartiromo.
Dr. Oz: "If we can get the average person to work one more year in their whole lifetime -- just stay in your workplace for one more year -- that is worth about $3 trillion to the US GDP. That's the productivity we would unleash ... if you're sick, you can't work." pic.twitter.com/9xixeDm2ux

"That's the productivity we would unleash of people feeling they have agency over their future, like they've got stuff they want to accomplish with their lives," Oz continued. "If you're sick, you can't work. So keep people healthy, they'll want to work, they'll want to produce, not just for one year but for many more... It's worth the investment to get that return."
"I love it," replied Bartiromo.
Oz's statement about getting Americans to work longer to improve national GDP was met with immediate criticism.
Journalist Brian Goldstone, who last year published a book focusing on Americans who are homeless despite having jobs, argued that Oz was simply clueless about the realities of working-class Americans.
"I recently met a widowed 71-year-old woman still working two jobs and living at an extended-stay hotel because even two jobs don't pay her enough to afford rent," he wrote in a post on Bluesky. "This is what 'one more year of work' looks like in America."
Economist Dean Baker of the Center for Economic and Policy Research noted that Oz doesn't seem to understand that most Americans don't have the kinds of cushy gigs he's enjoyed for decades.
"I'm sure everyone would be happy to work another year if work meant getting paid millions of dollars to spout utter nonsense on Fox, CBS, and other right-wing outlets," Baker remarked on X.
Baker also questioned the arithmetic behind Oz's claim about the vast benefits to the US economy of having everyone work for an extra year.
"I'm also curious where the hell he got the $3 trillion (10% of GDP)," he wrote. "I gather it is a Trump number, came straight out of his rear end."
Democratic political strategist Dan Kanninen said that Oz came off as utterly tone deaf about Americans' lives, and sarcastically encouraged the Trump administration to "put Dr. Oz and his 'Matrix' vision of the future where we all batteries for capital on the airwaves as much as possible."
Dell Cameron, a senior writer at Wired, argued that Oz's remarks were a damning indictment of former talkshow host Oprah Winfrey, who regularly featured purported experts of dubious credibility, including Oz, Phil McGraw, and João Teixeira de Faria, a Brazilian "faith healer" and convicted rapist currently serving a lifetime prison sentence.
"Hard to pin down which of the medical hacks platformed by Oprah's network has gone on to do the most harm, which is saying a lot since one is a cult leader who raped hundreds of women," he mused. "Then again, [Oz] is one of the most influential quacks of all time."

Latest GDP Figures Show Rich Reaping Rewards as Working Class Continues to Suffer Under Trump
"People at the top are doing fine, people in the middle and lower income brackets are struggling a bit, to say the least."
Dec 24, 2025
President Donald Trump's allies this week hyped up newly released data showing that the US economy grew by more than 4% in the third quarter of 2025, but economists and journalists who dove into the report's finer details found some troubling signs.
Ron Insana, a finance reporter and a former hedge fund manager, told MS Now's Stephanie Ruhle on Tuesday night that there is a "split economy" in which growth is being driven primarily by spending from the top 20% of income earners, whom he noted accounted for 63% of all spending in the economy.
On the other side, Insana pointed to retail sales data that painted a very different picture for those on the lower end of the income scale.
"When you look at lower income individuals, nearly half of them are using 'buy-now-pay-later' for their holiday shopping," he said. "So we have this real split... People at the top are doing fine, people in the middle and lower income brackets are struggling a bit, to say the least."
Dean Baker, co-founder and senior economist of the Center for Economic and Policy Research, also took note of this split in the US economy, and he cited the latest data showing that real gross domestic income, which more directly measures worker compensation over total economic output, grew at just 2.4% during the third quarter.
Baker also said that most of the gains in gross domestic income showed up at the top of the income ladder, while workers' income growth remained stagnant.
The theme of a split economy also showed up in an analysis from Politico financial services reporter Sam Sutton published on Wednesday, which cited recent data from Bank of America showing that the bank's "top account holders saw take-home pay climb 4% over the last year, while income growth for poorer households grew just 1.4%."
Sutton said that this divergence in fortunes between America's wealthy and everyone else was showing up in polling that shows US voters sour on the state of the economy.
"In survey after survey, a majority of Americans say they’re straining under the pressure of rising living expenses and a softening job market," Sutton said. "The Federal Reserve Bank of Boston says low-income consumers have 'substantially' higher levels of credit card debt than they did before the pandemic. Even as growth and asset prices soar, Trump’s approval ratings are sagging."
Economist Paul Krugman on Tuesday argued in his Substack newsletter that one reason for this large disparity in economic outcomes has to do with the US labor market, which has ground to a halt in recent months, lowering workers' options for employment and thus lowering their ability to push prospective employers for higher wages.
"Trump may claim that we are economically 'the hottest country in the world,' but the truth is that we last had a hot labor market back in 2023-4," Krugman explained. "At this point, by contrast, we have a 'frozen' job market in which workers who aren’t already employed are having a very hard time finding new jobs, a sharp contrast with the Biden years during which workers said it was very easy to find a new job."
None of these caveats about the latest gross domestic product (GDP) data stopped US Commerce Secretary Howard Lutnick from going on Fox News on Tuesday night and falsely claiming that a 4.3% rise in GDP meant that "Americans overall—all of us—are going to earn 4.3% more money."

In reality, GDP is a sum of a nation's consumer spending, government spending, net exports, and total investments, and is not directly correlated with individuals' personal income.
