President Donald Trump on Saturday hailed a decision by a major international climate panel to move away from one of its most extreme warming projections, using the shift to criticize Democratic climate policies and what he described as years of fear-driven messaging.

The United Nations-backed Intergovernmental Panel on Climate Change recently adjusted its framework that projected global temperatures could rise by 4–5°C by the year 2100. The model, known as RCP8.5, had been widely used in studies forecasting catastrophic outcomes tied to greenhouse gas emissions, including rising sea levels, widespread crop failures, and accelerated glacier melt.

“GOOD RIDDANCE! After 15 years of Dumocrats promising that ‘Climate Change’ is going to destroy the Planet, the United Nations TOP Climate Committee just admitted that its own projections (RCP8.5) were WRONG! WRONG! WRONG!” Trump wrote on Truth Social.

Trump, who has consistently promoted expanded domestic oil and gas production under his “drill baby, drill” agenda, has long rejected many mainstream climate change claims. During a United Nations address last year, he referred to climate change as a “con job.”

“For far too long Climate Activism has been used by Dumocrats to scare Americans, push horrible Energy Polices, and fund BILLIONS into their bogus research programs,” Trump added.

“Unlike the Dumocrats, who use Climate Alarmism nonsense to push their GREEN NEW SCAM, my Administration will always be based on TRUTH, SCIENCE, and FACT!”

Scientists involved in the updated assessment abandoned the high-end warming scenario in favor of seven other projections they argued provide a broader and more realistic range of possible climate outcomes.

“For the 21st century, this range will be smaller than assessed before,” the scientists wrote in the journal Geoscientific Model Development, adding that the worst-case projections “have become implausible.”

The Trump administration has reversed numerous climate-related regulations enacted during the Obama and Biden administrations. Earlier this year, EPA Administrator Lee Zeldin announced the rollback of an Obama-era greenhouse gas policy.

Some critics of climate alarmism have pointed to earlier predictions that failed to materialize, including warnings that glaciers in Montana’s Glacier National Park would disappear by 2020. Park officials later removed signs containing those projections after the glaciers remained.

Tech billionaire Bill Gates has also moderated some of his previous rhetoric, recently acknowledging that global warming is unlikely to lead to humanity’s “demise.”

Former Secretary of State Hillary Clinton criticized Trump’s remarks, calling them “total disinformation.”
