Biden official unable to provide cost estimate for fighting climate change.

Sen. John Kennedy questioned Deputy Energy Secretary David Turk on how much spending $50 trillion in American taxpayer money to become carbon-neutral would lower global temperatures, to which Turk was unable to provide a specific number. Kennedy criticized Turk for advocating spending trillions of dollars without being able to tell how much it would lower world temperatures. Some climate experts have claimed it will cost $50 trillion for the US to reach carbon neutrality, but critics argue that there is no guarantee spending that amount would have any effect on climate change across the globe if other countries don't take similar action.
