Kennedy: $50T To Make USA Carbon Neutral, How Much Will It Lower World Temperatures? Witnesses Can’t Say

In February 2023, Senator John Kennedy continued budget hearing questioning on climate policy economics, asking pointed follow-up on the benefit side of cost-benefit analysis. “If we spend $50 trillion to make the United States of America carbon neutral by 2050, how much will that lower world temperatures?” Kennedy asked. The witness responded: “I can’t understand because we don’t know what China and India and the rest of the globe has done.” Kennedy continued: “Have you heard anybody from the Biden administration say how much it will lower world temperatures?” Witness: “No.” Kennedy: “Does anybody know how much it will lower world temperatures?” Witness: “No. No one can know for sure.” Kennedy then turned to Dr. Litterman: “If we spend $50 trillion or however much it takes to make the United States carbon neutral by 2050, how much will it lower world temperatures?” Litterman: “Senator, that depends on the rest of the world. We have to work with the rest of the world. We’re in this together. It’s one world. We can’t go to the wall around the United States and see.” Kennedy pressed: “What if we spend $50 trillion? Europe cooperates. Most Western democracies cooperate, but India and China don’t.”

The Kennedy Follow-up Strategy

Strategy:

Cost established — $50T.

Benefit question — Next.

Full analysis — Sought.

Substantive — Framework.

Logical — Progression.

Kennedy’s follow-up strategy after establishing cost at $50T moved to benefit question seeking full analysis. Substantive framework for cost-benefit analysis. Logical progression building political narrative.

The Temperature Reduction Question

Question:

Specific — Metric.

Global — Framework.

Measurable — Impact.

Scientific — Question.

Substantive — Inquiry.

Kennedy’s temperature reduction question had specific metric framework on global measurable impact. Scientific question seeking substantive inquiry into actual climate policy effectiveness.

”Can’t Understand” Response

Response:

Witness uncertainty — Admitted.

China/India factor — Cited.

Limited — Knowledge.

Honest — Element.

Political — Problematic.

First witness’s “can’t understand” response admitted uncertainty while citing China/India factor. Limited knowledge honest element. Politically problematic for climate policy advocacy without benefit estimates.

The China/India Factor

Factor:

Major emitters — Yes.

Growing emissions — Both.

US action alone — Insufficient.

Cooperation — Required.

Reality — Global.

The China/India factor as major growing emitters meant US action alone was insufficient. Cooperation required. Global reality of climate policy depending on non-US actions affecting benefit calculations.

”Biden Administration Say How Much”

Kennedy question:

Administration source — Sought.

Benefit articulation — Required.

Policy advocacy — Basis.

Accountability — Through questioning.

Substantive — Challenge.

Kennedy’s “heard anybody from the Biden administration say how much it will lower world temperatures” sought administration source for benefit articulation as policy advocacy basis. Substantive accountability challenge.

”No” Responses

Responses:

Consistent — No from all.

Administration — Silent.

Experts — Unable.

Substantive — Gap.

Political — Impact.

Consistent “No” responses from administration silence and expert inability revealed substantive gap between cost and benefit knowledge. Significant political impact of the lack of benefit articulation.

”No One Can Know For Sure”

Uncertainty:

Honest — Acknowledgment.

Models — Imprecise.

Variables — Too many.

Complex — System.

“No one can know for sure” honest uncertainty acknowledgment reflected scientific reality with imprecise models due to too many variables in complex global climate system.

The Dr. Litterman Response

Litterman:

Senator addressed — Respectfully.

Global — Framing.

“One world” — Language.

Cooperation — Emphasized.

Scientific — Framing.

Dr. Litterman’s respectful “Senator” addressing with global “one world” framing emphasizing cooperation used scientific framing about interconnected climate challenge requiring global action.

”Depends on the Rest of the World”

Depends:

Global dependency — Real.

US alone insufficient — Admitted.

Cooperation — Required.

Substantive — Reality.

Complex — Diplomacy.

“Depends on the rest of the world” global dependency admission that US alone was insufficient requiring cooperation was substantive reality. Complex diplomacy dimension of climate policy.

”We Have to Work With the Rest of the World”

Cooperation:

Philosophy:

Interconnection — Acknowledged.

Shared fate — Climate.

Cooperative — Approach.

Idealistic — Element.

Framework — Standard.

“One world” philosophy acknowledged interconnection through shared climate fate with cooperative approach. Somewhat idealistic element in standard climate framework about global solutions.

”Wall Around the United States”

Metaphor:

Isolation impossible — Climate.

Global scale — Required.

US alone — Insufficient.

Cooperation — Only way.

Standard — Argument.

Litterman’s “can’t go to the wall around the United States and see” metaphor made isolation impossible argument for climate requiring global scale cooperation as only effective way.

Reality:

Coal use — Continuing.

Emissions growing — Rapidly.

Economic development — Priority.

Climate commitments — Limited.

Substantive — Problem.

India/China reality with continuing coal use and rapidly growing emissions prioritizing economic development over climate commitments created substantive problem for global climate goals regardless of US action.

The Free Rider Problem

Free rider:

Climate benefits — Public good.

Costs — Localized.

Incentive — To not contribute.

Classic — Economic.

Substantive — Challenge.

Free rider problem had climate benefits as public good with localized costs creating incentive to not contribute. Classic economics challenge. Substantive political economy problem for climate policy.

The US Leadership Argument

Leadership:

Moral — Framing.

Example setting — Priority.

Even without cooperation — Value.
