On inauguration day, President Trump reaffirmed his intention to withdraw from the Paris Climate Agreement and declared an energy emergency aimed at boosting fossil fuel production. European leaders pledged to uphold the Paris accord, with UN climate chief Simon Stiell asserting the global energy transition is inevitable. Critics focus on the detrimental effects of U.S. withdrawal on developing nations and emphasize the need for collective climate action, as public polls reveal significant opposition to Trump's decision. Experts note the potential loss of U.S. credibility in climate diplomacy and its implications for future energy policy.
