Donald Trump’s return to the presidency signals a potential roadblock for global climate change initiatives, particularly ahead of the upcoming UN climate talks, COP29. Experts warn that his skepticism towards climate policies could hinder efforts to cut emissions and support developing nations financially. Unlike his previous term, this time Trump could swiftly withdraw the US from the Paris Agreement, exacerbating global inaction. Meanwhile, ongoing public support for renewable energy may challenge his intentions to prioritize oil and gas exploration. The overall impact of his presidency on climate action remains uncertain as global leaders prepare for COP discussions.
