Climate-change activists haven’t run out of steam yet, but the formerly red-hot movement is looking increasingly gassed.
President Trump has taken a sledgehammer to the global-warming apparatus as he supercharges oil-and-gas development; Europe is walking back its net-zero emissions targets; and climate guru Bill Gates shook the movement last year by repudiating its “doomsday” scenarios.
New York Gov. Kathy Hochul, a Democrat, wants to delay the state’s ambitious 2030 emissions targets, arguing that they cannot be met without saddling residents and businesses with “new and additional crushing costs.”
Even Greta Thunberg has moved on.
The world’s best-known climate activist has pivoted to other causes such as the Gaza War, before reemerging last month as an ardent defender of the communist Castro regime in Cuba.
What happened? Lee Zeldin, Environmental Protection Agency administrator, gave a hat-tip Wednesday to the crowd at the Heartland Institute’s 16th International Conference on Climate Change, an annual gathering of climate skeptics and realists.
“This morning and today, all of you gathered here in D.C., is a moment to celebrate,” Mr. Zeldin told attendees at the sold-out conference, titled “Climate Realism Rising.”
“It is a day to celebrate vindication,” he proclaimed.
Critics of the climate movement argue that the issue is collapsing under its own weight after 20 years of dire warnings and trillions of dollars spent on reducing emissions with virtually no measurable impact on global temperatures.
Bjorn Lomborg, president of the “lukewarmist” Copenhagen Consensus Center, said last week that an estimated $14 trillion has been spent on the “global green transition,” to little avail.
International greenhouse-gas emissions set another record in 2025, mostly fueled by economic growth in China, India and Africa as poor countries eager for prosperity wash over the small emissions cuts in first-world nations.
“I think part of that is just the fact that the public by and large is finally becoming attuned to the fact that there’s a great disparity between what’s been predicted and what has transpired,” said Kevin Mooney, author of the newly released book, “Climate Porn: How and Why Anti-Population Zealots Fabricate Science, while Targeting American Capitalism, Freedom, and Independence.”
He said Americans are doing the cost-benefit analysis as energy prices rise while states seek to achieve net-zero emissions by transitioning to solar and wind power.
“Are we really going to spend buckets of money and reorganize our lives for something that might have a marginal influence on the planet at most?” Mr. Mooney asked in an interview with The Washington Times.
At the tip of the spear is Mr. Trump, who has made rolling back policies predicated on the climate “hoax” a central tenet of his administration.
He delivered a devastating setback to the climate movement this year by targeting two of its pillars: the Environmental Protection Agency’s 2009 Endangerment Finding, which listed carbon dioxide as a dangerous pollutant, and the 1992 United Nations Framework Convention on Climate Change.
Mr. Trump announced in January the U.S. withdrawal from the UNFCCC, the 24-year-old accord that created the structure for international climate cooperation and led to the 2015 Paris climate agreement – which the president has also exited.
In February, the EPA announced its final rule rescinding the Endangerment Finding, which classified carbon dioxide as a dangerous pollutant, the legal basis of the agency’s ability to regulate greenhouse-gas emissions.
Twenty-four Democratic attorneys general filed a lawsuit last month challenging the rollback, accusing the administration of putting the public at risk by failing to take seriously the climate “crisis.”
“Instead of helping Americans face our new reality, the Trump administration has chosen denial, repealing critical protections that are foundational to the federal government’s response to climate change,” said New York Attorney General Letitia James in a March 20 statement.
The new reality for Democrats, however, is that climate change appears to be losing its cool factor on the left as other issues take priority, including illegal immigration, the Iran war, the Gaza war, and taxing the rich.
Marc Morano, publisher of Climate Depot, a project of the Committee for a Constructive Tomorrow, said that the administration has been “the most consequential dismantler of the entire climate agenda since its inception.”
“I have been on the climate beat for over 25 years, and I have never seen anything like this,” he told The Times. “Trump is gutting everything the climate movement has ever stood for. Billionaires are silent or reversing themselves on climate, and even Democrats in Congress have been mostly silent as Trump crushes the climate movement. There has been no pushback!”
He pointed out that “Lee Zeldin routinely labels climate a ’cult’, a ’scam’, and a ’religion’, and he doesn’t even get pushback from reporters,” Mr. Morano said.
“I think a great birthday gift to America is President Trump getting us out of these international climate agreements”

Climate groups point to polls showing that warming remains a concern. A 2025 Gallup survey showed that 48% of those polled agreed that climate change is a “serious threat,” up from 25% in 1997.
Behind the scenes, however, Democrats are being advised to keep the climate at arm’s length in the 2026 midterm election.
The liberal Searchlight Institute cautioned Democratic candidates against using the term “climate change,” citing polling showing that the issue isn’t resonating with swing-state voters.
Only 6% of battleground-state voters said that climate change is their top issue, according to the institute in a September analysis titled, “The First Rule About Solving Climate Change: Don’t Say Climate Change.”
“While battleground voters overwhelmingly agree climate change is a problem, addressing it is not a priority for them,” the institute said. “While some policies that help fight climate change are modestly popular, Americans care far more about energy affordability than they do about climate.”
The pushback coincides with the 20th anniversary of “An Inconvenient Truth,” the Oscar-winning documentary film starring former Vice President Al Gore that launched the international climate-change movement.
Unfortunately for climate activists, many of its apocalyptic predictions aren’t aging well, starting with the forecasted increase in catastrophic natural disasters.
Polar-bear populations have increased; hurricane frequency has declined slightly; the area burned by wildfires has decreased globally by 25%, and the number of people killed in natural disasters has plummeted in the last 100 years by 97%, according to data cited by Mr. Lomborg in the May 2026 issue of National Review.
Rep. Alexandria Ocasio-Cortez, New York Democrat, famously warned in 2019 that “the world’s gonna end in 12 years if we don’t address climate change,” a forecast that appears to be in danger of falling short.
Mr. Mooney credited scientists and analysts who have published research challenging the global-warming assumptions, despite the risk to their own careers from being labeled “deniers.”
He argued that the danger is less rising global temperatures than ushering in centralized government control, meaning that another collectivist movement could rise from the ashes if the climate movement burns itself out.
“I think we’ll still be fighting this battle for a while,” said Mr. Mooney, an investigative reporter for Restoration News, a publication of the conservative Restoration of America Foundation. “If it’s not climate, you’ll see a new avenue for collectivism and leftism.”
In the meantime, he encouraged the Trump administration to stay the course.
“This is the big domestic success story coming out of the Trump administration: dismantling the climate-industrial complex,” Mr. Mooney said. “The administration from my point of view is aiming its arrow in the right direction. I wouldn’t say the movement is dead, but it’s in its death throes.”
