The National Climate Assessment (NCA), a critical tool for understanding and addressing climate risks, is in dire need of reform. Despite its noble intentions, the NCA has fallen short of providing practical guidance to decision-makers, leaving a gap in our ability to effectively respond to the growing threats posed by climate change.
As an interdisciplinary climate and decision scientist, I've had the opportunity to review the NCA and engage with its purpose and potential. My conclusion is clear: the NCA, as it stands, is broken, and urgent action is required to fix it.
The core issue is that the NCA focuses primarily on identifying risks without offering a comprehensive roadmap for managing them. It's akin to a doctor diagnosing a serious illness but failing to provide treatment options or insights into the experiences of others facing similar challenges. This omission limits its value for leaders in business and government who are seeking actionable strategies to navigate the complex landscape of climate change.
The Problem with the Current Approach
Scientists who develop assessments like the NCA often prioritize evidence over recommendations, avoiding explicit value judgments. While this restraint is understandable, it has resulted in a report that enumerates risks but falls short of offering practical guidance. As climate risks become increasingly acute, this omission becomes a critical flaw.
Imagine a business leader or government official reading the NCA. They might feel overwhelmed by the severity of the risks outlined but left without a clear path forward. This lack of direction can lead to paralysis, a dangerous outcome when timely action is crucial.
The Trump Administration's Role
The appointment of Matthew Wielicki, a former geochemistry instructor and climate science critic, to lead the US Global Change Research Program (USGCRP) and oversee the NCA is a cause for concern. Given the administration's history of dismantling climate initiatives and promoting climate skepticism, it's reasonable to expect that Wielicki's leadership could further undermine the NCA's credibility and effectiveness.
The administration's previous actions, such as commissioning a report by climate skeptics to dismiss the risks of climate change, suggest a pattern of denial and misinformation. With the world experiencing some of its hottest years on record and Americans facing worsening climate impacts, the need for accurate and actionable information is more critical than ever.
A New Approach: Sharing Solutions
The real fix for the NCA is not to deny the existence of climate change but to expand its focus. The NCA should provide better advice on managing climate risks, offering a range of national and local options for adaptation and mitigation. It should also guide decision-makers on the most appropriate strategies for different places and climate scenarios, and offer insights into the decision-making process itself.
An improved NCA should build a searchable library of practical and relatable case studies. These case studies should describe real-world examples of climate risk management, such as New York City's scenario planning for sea-level rise, Flagstaff's use of a ballot initiative to address flood and wildfire risks, and the experiences of cities like Burlington and Georgetown after transitioning to renewable energy.
These case studies should be candid about the strengths and weaknesses of different options, including maintaining the status quo. They should also provide guidance on adapting lessons from one case to different contexts and risks, and be updated over time to reflect the latest outcomes and developments.
The Way Forward
An enhanced NCA, with a focus on sharing solutions and practical examples, would be a powerful tool for decision-makers. It would empower leaders in business and government to make informed choices, weighing the costs, benefits, and uncertainties associated with different climate risk management options. It would also help them understand the trade-offs of acting now, delaying action, or choosing to do nothing.
By learning from the experiences of others, decision-makers can develop a better understanding of the complex web of factors that influence climate action. This knowledge is essential for preparing for the future and making informed decisions when it's their turn to act.
In conclusion, the National Climate Assessment needs a radical overhaul to become a truly useful tool for addressing climate change. It's time to shift the focus from simply identifying risks to providing practical guidance and real-world examples of successful climate risk management. With the right leadership and approach, the NCA can become a powerful resource for a more resilient and sustainable future.
