John Kennedy Vs Energy Secretary: '$50 Trillion for Net Zero, No Idea If It Reduce Temperatures?'

Senator John Kennedy grills the U.S. Deputy Secretary of Energy on net zero:

"If we spend $50 trillion to become carbon neutral by 2050, how much is that going to reduce world temperatures?"

"You don't know, do you? You just want us to spend $50 trillion, and you don't have the slightest idea whether it's going to reduce world temperatures."
