Every few years, debates about global warming circle back into the spotlight, and this time the noise is coming from scientists who say the picture isn’t nearly as simple as the public has been led to believe.
They argue that the root causes of rising temperatures remain murky — and that money, not science, now drives most big climate decisions.
The Scientist Challenging the Crisis Narrative
Richard Lindzen, a longtime meteorologist and MIT professor emeritus, has spent much of his career studying how Earth’s atmosphere behaves.
Speaking to the Daily Mail, he didn’t mince words: in his view, the growing panic about the planet heating up is built on shaky foundations, not solid evidence.
How the Public Came to See Climate Change
Climate change is widely described as a human-made warming trend, mainly tied to burning fossil fuels such as oil, coal, and natural gas.
Activists and researchers have warned that without drastic cuts, the next couple of decades could bring stronger storms, flooded coastlines, and blistering summers that strain global food production.
Lindzen’s Argument: Politics First, Science Second
But Lindzen insists the real engine behind all of this is financial.
With the global energy sector worth many trillions, he argues that the possibility of reshaping that system was irresistible to politicians.
According to him, this led to exaggerated narratives claiming tiny temperature changes would unleash disaster.
“Another half degree and we’re doomed” is how he summarized the messaging — and he believes the public instinctively sees through it.
Why He Says the Numbers Don’t Add Up
Lindzen breaks down his skepticism by pointing to the basic calculations behind climate projections.
In his view, lowering CO₂ — the gas most often blamed — simply cannot produce the dramatic temperature swings predicted.
Earth, he says, has seen large warm and cold periods over history, long before heavy fossil-fuel use.
He even pointed to the Little Ice Age around the 15th century, asking what caused that shift if carbon dioxide levels weren’t the culprit.
The Massive Money Flow Behind Energy and Research
Data from the International Energy Agency puts the global energy market at around $6 to $7 trillion.
Despite efforts to move toward renewables, fossil fuels still provide over 80 percent of the world’s energy.
Yet investment tells a different story: governments and corporations poured a record $2.2 trillion into clean-energy projects this year — twice as much as the amount going into fossil fuels.
In the U.S., billions more have been funneled into climate programs, including the Biden administration’s $27 billion Greenhouse Gas Reduction Fund.
The CO₂ Debate: Villain or Misunderstood Player?
Lindzen argues that CO₂ has been unfairly demonized.
He calls it a relatively weak greenhouse gas that actually supports plant growth.
He believes the focus on it has helped funnel enormous research grants to universities, rewarding studies that reinforce climate-alarm messaging.
Federal agencies are now spending up to $5 billion a year on climate-related research.
The White House’s 2024 budget alone sent $1.6 billion to universities and NGOs studying potential warming-driven disasters.
Claims of Silencing and Rejected Research
Lindzen has long said that challenging mainstream climate models carries consequences — including having research dismissed or seeing sympathetic journal editors pushed out.
He repeated those concerns on the Joe Rogan Experience podcast.
Judith Curry, formerly of Georgia Tech, has also spoken publicly about research being “filtered out” of academic journals.
She once said one of her co-authors selectively highlighted a small warming trend while ignoring data showing temperatures leveling off for over a decade.
What Climate Models Predict for the Future
Current published models warn that letting temperatures rise more than 2.7°F above pre-industrial levels could trigger irreversible melting of ice sheets, deadly heat waves, and major agricultural failures by mid-century.
Lindzen counters that doubling CO₂ concentrations would only warm the planet by roughly half a degree on its own — far below what many models predict.
The Iris Effect: A Natural Safety Valve?
Many catastrophic projections rely on the assumption that warming automatically causes more water vapor — which traps far more heat than CO₂.
Lindzen argues the opposite happens.
His “Iris effect” theory suggests that when tropical regions heat up, intense thunderstorms create cloud openings that vent heat into space, acting as a natural cooling mechanism.
The High Cost of Net-Zero — For Minimal Change?
Lindzen also claims that even if countries worldwide achieved net-zero emissions by 2050, the impact on global temperature would be tiny — a fraction of a degree.
But the price tag, he warns, could climb into the hundreds of trillions of dollars, a cost he believes is wildly disproportionate to the benefit.
CO₂ and the Planet’s Greenery
He adds that CO₂ enhances plant growth and reduces water needs, boosting global food production.
In his view, today’s levels are still low in geological terms.
He estimates the rise so far may have increased arable land by up to 40 percent.
Growing Dissent Among Prominent Voices
Lindzen isn’t alone. Several influential figures — including Bill Gates — have started tempering their earlier urgency, saying the world should perhaps focus more on issues like nuclear conflict.
Former activist Ted Nordhaus has also criticized what he calls shifting goalposts in climate predictions.
Earlier models projected close to 9°F of warming by 2100.
As those estimates fell, he said climate advocates began warning that even 5°F would bring the same catastrophic results.
A Debate That Isn’t Settling Down Anytime Soon
Nordhaus now believes even the most extreme warming scenarios aren’t consistent with the apocalyptic outcomes he once feared.
And as more experts publicly express doubts or frustration with climate science’s direction, Lindzen says the tide may be turning — and that future generations might look back at today’s climate panic with embarrassment.
