I break down the latest Trump speech, sifting through the wide-ranging climate change misinformation it contains. On September 23rd 2025, President Donald Trump took to the United Nations. Instead of calling for harmony and co-operation, his one hour speech fixated on migration and climate change. This might just be the first time a president of the USA has spent so much time talking about climate... but the speech wasn't a call to action. It was dismissal and denial of everything from basic science to renewable technologies. So what's the truth behind Trump's claims?
