Trump to UN: “greatest con job ever”

U.S. President Donald Trump once again denounced the international Climate Change lobby, this time during his UN address on September 23, 2025.

“This ‘climate change,’ it’s the greatest con job ever perpetrated on the world, in my opinion. All of these predictions made by the United Nations and many others, often for bad reasons, were wrong. They were made by stupid people that have cost their countries fortunes and given those same countries no chance for success. If you don’t get away from this green scam, your country is going to fail.”

While some will dismiss his statement as more hyperbole from the colorful president, authentic climate science is on his side. Over 1880 researchers have signed a declaration stating that there is ‘no climate emergency’, including Nobel Prize winner, John F. Clauser. David Siegel, one of the signatories, declared: “It’s clear that CO2 has almost nothing to do with climate” — unlike data showing that ocean currents have more impact than the so-called “Greenhouse effect”.

The mainstream media, on the other hand, continues a false narrative. Take Euro News headline in response to Trump’s address: “Trump calls climate change a ‘con job’ as leaders of drowning nations watch at the UN”. On the contrary, a peer-reviewed study published this past August reveals that the average rate of sea level rise in 2020 was well below other widely cited analyses, and that when projections were compared with local data, there was little evidence climate change was driving the acceleration seen in a few regions .

“Overall, this study indicates that in most places, sea levels are not rising unusually quickly. In the relatively few locations where sea levels are rising faster than average, the cause is almost certainly local factors such as land subsidence or ground compaction,” Sterling Burnett, director of the Arthur B. Robinson Center on Climate and Environmental Policy at The Heartland Institute. “Global sea levels are currently rising more slowly than they have for much of the time since the last ice age ended — a period during which seas rose more than 400 feet. Any possible increase in the recent rate of rise compared with the past century is small, within the margin of error, and not outside historical patterns.”1

Adelle Thomas, a climate scientist and vice chair of the United Nations Intergovernmental Panel on Climate Change (IPCC), claimed she experienced firsthand “the devastation of the climate disaster” when Hurricane Sandy hit the Caribbean and New York City.2 But documentarian, John Leake, says, “Critical readers may wonder why Adelle Thomas would point to Sandy—a Category 3 hurricane—as evidence of human induced “climate change.”

The most destructive hurricane in recorded history was the Great Hurricane of 1780, a Category 5 hurricane that struck Barbados, causing massive damage to the entire island. Based on observations recorded at the time—including pieces of straw driven deep into tree trunks—the hurricane is estimated to have produced 200 mph wind. The Great Hurricane also struck other islands in the Lesser Antilles, is considered the deadliest in Atlantic history, with total fatalities possibly reaching over 22,000.

Thomas went on to claim: “Millions of people around the world can already testify to the devastation that climate change has brought to their lives,” she said. “The evidence is not abstract. It is lived, it is deadly, and it demands urgent action.”2 Sure. That’s what Greta Thunberg said.

On the contrary, an Italian review of extreme weather says there is ‘no evidence’ of ‘climate crisis’ in current data, according to their paper. In fact, there has been a decrease in hurricane activity. Then there is the claim that climate is killing people when “ever fewer people die from climate-related catastrophes,” wrote Bjørn Lomborg, former director of the Danish government’s Environmental Assessment Institute. “As population has quadrupled, deaths have dropped 20-fold,” he said (see this graph). “Death risk from climate is down 99% from the 1920s.”

However, those who have been following the rhetoric of the likes of Thomas and the IPCC will already be suspicious. The IPCC has been caught several times fudging data in order to rush forward their agenda, most notably, the Paris Climate Agreement, which really has nothing to do with the environment. Rather, it’s about the redistribution of global wealth through punishing “carbon taxes”:

But one must say clearly that we redistribute de facto the world’s wealth by climate policy. Obviously, the owners of coal and oil will not be enthusiastic about this. One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with environmental policy anymore…

Ottmar Edenhofer, IPCC, dailysignal.com, November 19th, 2011

The IPCC was caught exaggerating data on Himalayan glacier melt; they ignored that there was indeed a ‘pause’ in global warming: top climate scientists were instructed to ‘cover up’ the fact that the Earth’s temperature hadn’t risen for the last 15 years. The University of Alabama in Huntsville, considered the most reliable in gathering global temperature data sets developed from satellites, has shown that there has been no global warming at all for the last seven years (as of January 2022). Climate scientists there, John Christy and Richard McNider, found that by removing the climate effects of volcanic eruptions early on in the satellite temperature record, there showed virtually no change in the rate of warming since the early 1990s.

These are but a few examples that we pointed out in Hot Air — Behind the Wind of the problematic if not fraudulent science being foisted on the public. Trump gave another example:

Another UN official stated in 1989 that within a decade, entire nations could be wiped off the map by “global warming.” Not happening.

Euro News, September 24, 2025

In fact, the increase of carbon dioxide (of which man plays an insignificant role) in our atmosphere is actually greening the planet, which is better for vegetation and food production. A study in Nature has found that “woody vegetation cover over sub-Saharan Africa increased by 8% over the past three decades… These results confirm global greening trends, thereby bringing into question widely held theories about declining terrestrial carbon balances and desert expansion.”3 The National Oceanic and Atmospheric Association reported a study in 2018 showing “Global plant growth surging alongside carbon dioxide.”4 NASA’s mapping shows “that the world is greener than it was in the early 1980s.”5 Boston University’s study found “significant greening of something between 25% and 50% of the Earth’s vegetated land.”6 Moreover, such greening actually cools the earth.7 There’s more studies along this same vein, but you get the picture.

Whether you love or hate Trump, when it comes to climate change, he’s right. As governments punish their citizens with carbon taxes and impose environmentally harmful and unreliable technologies such as wind and solar (which historically have driven up the cost of electricity); when they talk about eliminating cheap and available fossil fuels while demanding everyone move to electric heat and vehicles with already failing power grids…. it clearly is a con-job of the highest order.

Trump just has the guts to say out loud what many politicians will only whisper away from the microphone.
