President Donald Trump celebrated after reports claimed a United Nations climate committee had moved away from one of its most extreme global warming scenarios, calling the development a major victory over climate alarmism.
The discussion centered on the RCP8.5 scenario, a high-emissions model that has often been used in climate projections to describe severe possible warming outcomes.
Trump and his supporters argued that climate activists and Democratic politicians had relied on extreme projections for years to justify aggressive green energy policies and large government spending programs.
In a post shared online, Trump claimed the shift showed that previous climate warnings had been exaggerated and used to scare Americans.

“For too long, climate activism has been used to push bad energy policies and fund billions of dollars into questionable research programs,” Trump wrote.
Supporters praised the comments, saying the administration’s energy policy would focus on what they described as common sense, affordability and scientific accuracy rather than alarmist predictions.
The issue quickly gained traction among conservative commentators, who argued the development undermines years of warnings about climate catastrophe.
Critics of Trump’s position, however, continue arguing that climate change remains a serious global challenge and that long-term environmental risks should not be dismissed because of debate over one emissions model.
RCP8.5 has been widely discussed in climate research as a worst-case pathway, but some scientists have argued in recent years that it should not be treated as the most likely future scenario.
The debate has fueled broader political arguments over energy independence, fossil fuels, renewable energy investments and the role of government in climate policy.
Trump has repeatedly criticized climate regulations, saying they hurt American workers, increase energy costs and weaken U.S. competitiveness.
His administration has instead emphasized domestic energy production, lower fuel prices and reducing what it calls unnecessary environmental restrictions.
The latest reaction is expected to intensify political debate over climate science, green energy spending and whether government policies should be based on worst-case projections or more moderate assumptions.
