Trump Undermines Global Climate Efforts in UN Speech Amid Rising Diplomatic Tensions

At the 2025 United Nations General Assembly, President Donald Trump delivered the longest U.S. presidential speech in the body’s history, dedicating significant time to dismissing climate change as a "greatest con job ever perpetrated on the world" and branding renewable energy as a "scam." He criticized carbon accounting and environmentalists, portraying green energy efforts negatively, while promoting American fossil fuels. This stance came at a diplomatic moment when China reaffirmed its commitment to reducing emissions, positioning itself as a leader in global climate efforts with a new goal for 2035. Trump's remarks drew sharp backlash from world leaders and scientists who warned that ignoring climate action endangers vulnerable populations and undermines global progress. Experts refuted Trump’s claims, highlighting that renewable energy is increasingly cost-effective worldwide, and the UN continues to emphasize the importance of transitioning to green energy. The stark contrast between Trump’s climate skepticism and international efforts underscores the diplomatic and environmental challenges ahead at the upcoming COP30 UN climate conference in Brazil.
