Trump spoke for several minutes out of his near-hour speech on climate change during his address to the United Nations General Assembly, criticizing the European Union for reducing its carbon footprint, which he claimed has taken a toll on its economy, and warning countries that have invested heavily in renewable energy that their economies will suffer.

“It’s the greatest con job ever perpetrated on the world, in my opinion,” Trump told the General Assembly. “All of these predictions made by the United Nations and many others, often for bad reasons, were wrong.”

He added: “They were made by stupid people that have cost their country’s fortunes and given those same countries no chance for success.”
