Climate activists reacted negatively to the US election results, anticipating a setback in global climate action under President-elect Donald Trump, who plans to withdraw from the Paris Agreement. European leaders express concern over the US's potential lack of leadership in climate negotiations, emphasizing the EU's moral imperative to address climate change and support vulnerable nations. Despite worries about Trump's administration, some believe that the US's past withdrawal was more symbolic than effective, and the EU must step up as a global leader in climate policy.
