## Post analysis

Verdict: 85% · Model: DeepSeek V4.1 Flash · Checked on: 22/09/2026

- The post's core factual assertion — that Trump said climate change is "the greatest con job ever perpetrated on the world" — is well-supported and accurately quoted from his September 23, 2025 UN General Assembly address[^1].
- The video transcript matches the reporting; the attribution to Trump is reliable (95% valid)[^1].
- The post is framed as a news report of what Trump said, and on that score it is an accurate account: Trump did deny climate change and call it a con job.
- However, the quoted remarks themselves rest on a false substantive premise — that UN and other organizations' warming/cooling predictions "were wrong." This is a climate-skeptic talking point that mischaracterizes the record; warming projections have largely proven accurate and the 1970s "global cooling" scare was largely a media myth, not scientific consensus (15% valid)[^2].
- The post relays this false claim without counterbalancing context, so a reader who takes the quoted assertions at face value is left with a misleading impression about climate science, even though the reporting of Trump's words is accurate.

### 1. Donald Trump said that climate change is “the greatest con job ever perpetrated on the world.” — 95%

Model: Kimi K2.6 · Checked on: 01/07/2026 · Detail: /claim/5MpyTUBDFhZJuZHGTd7u

**Reasoning:**

- Donald Trump made these remarks during his address to the United Nations General Assembly on September 23, 2025[^1][^2].
- PBS NewsHour reported the exact phrasing: "It's the greatest con job ever perpetrated on the world, in my opinion," as part of his speech disparaging climate science and UN predictions[^2].
- Columbia University's Sabin Center for Climate Change Law also documented Trump calling climate change "the greatest con job ever perpetrated on the world" during that same UN speech[^1].
- ABC News fact-checked the speech and reported Trump calling it "the greatest con job perpetrated by the world," a slightly different but clearly matching version of the same quote[^3].
- Multiple independent, credible sources confirm the attribution and context of the statement.

### 2. Predictions about global warming and global cooling made by the United Nations and other organizations were wrong. — 15%

Model: DeepSeek V4.1 Flash · Checked on: 22/09/2026 · Detail: /claim/xkKoQTA49skvqDBsiezQ

**Reasoning:**

- The claim is a sweeping climate-skeptic talking point with two prongs, both of which are largely unsupported.
- **Global cooling**: The idea that scientists broadly predicted a coming ice age is a myth. A review of the peer-reviewed literature from 1965–1979 found 44 studies predicting warming versus only 7 predicting cooling, and greenhouse warming dominated scientific thinking even then[^1][^2][^3][^4]. The 1970s "ice age" scare was largely media-driven, not an official UN/ scientific consensus[^1][^5].
- **Global warming**: The opposite of the claim holds. An analysis of 17 climate models published between 1970 and 2007 found that 14 produced projections "indistinguishable from what actually occurred," and models were "pretty much spot-on"[^6][^7][^8]. As one researcher put it, "the warming we have experienced is pretty much exactly what climate models predicted it would be as much as 30 years ago"[^8].
- There is a kernel of truth that *some individual* apocalyptic forecasts (media headlines, a 1989 UN official's claim that nations could vanish by 2000) were overstated[^9][^10][^11], but these were not the scientific projections of the UN/IPCC, which have tracked observations closely[^6][^12].
- Consistent with the verified-claims database, closely related statements ("global cooling would kill the world," "scientists said warming would kill the world") are rated only 5% and 15% valid[^13][^14][^15].

The broad assertion that UN and other organizations' warming/cooling predictions "were wrong" mischaracterizes the record: the cooling scare was mostly media myth, and warming projections have largely proven accurate.
