Pandemic Risk Assessment and its Intersection with Climate Change: Needs, Opportunities, and Design Considerations

NAM

Background Information

The increasing frequency and severity of infectious disease outbreaks—driven by factors such as climate change, new methods of land use, urbanization, and global interconnectedness—underscore the urgent need for robust pandemic risk assessment frameworks. Future pandemics, which will likely be exacerbated by complex anthropogenic factors and inadequate systems for infectious disease surveillance and response, pose a substantial and underappreciated risk to both global health and economic well-being, with expected economic losses comparable to those of climate change (Fan et al., 2018). Despite the magnitude of these threats, pandemic risk remains poorly understood, supported by fragmented and insufficiently cumulative research, and limited quantitative assessment tools exist to understand these risks.

Against this backdrop, the United Nations Foundation (UN Foundation), in collaboration with the United States (US) National Academy of Medicine (NAM), the Fundação Oswaldo Cruz (Fiocruz), and the Global Pandemic Monitoring Board (GPMB) and with support from Pax sapiens and the Skoll Foundation, organized a workshop on October 28–29, 2024, in Rio de Janeiro, Brazil, titled Pandemic Risk Assessment and its Intersection with Climate Change: Needs, Opportunities, and Design Considerations. The workshop brought together a global multidisciplinary group of health leaders, scientists, and policymakers to address the pressing need to develop a pandemic risk assessment agenda, with particular attention to climate change as a driver of risk, but also considering a broader set of contributing factors. The workshop aimed to examine existing systems and methodologies for assessing pandemic risk; identify the challenges of linking climate and health data; and propose actionable steps to enhance global capacity to identify and quantify risk drivers, estimate economic and health impacts, and monitor change in risk levels.

Meeting Summary

Welcome Remarks

The workshop opened with remarks from Dr. Victor Dzau, NAM, and Dr. Maria de Lourdes Aguiar Oliveira, Fiocruz. Dr. Dzau reflected on the lessons of COVID-19 and highlighted the complex interplay between climate change, human activity, and infectious disease emergence. He emphasized the need for comprehensive frameworks to monitor and mitigate pandemic threats and called for a global pandemic monitoring mechanism that would provide multidisciplinary assessments to inform policies and build resilience. Dr. Oliveira underscored Fiocruz’s 124-year legacy in public health and highlighted its pivotal role in pandemic response, including the COVID-19 crisis, as well as its contributions to genomic surveillance, wastewater monitoring, and diagnostic networks. She stressed the importance of cross-sector collaboration and equitable partnerships to address the interconnected challenges of pandemics and climate change.

The panel included Dr. Rachel Baker, Brown University School of Public Health: … Dr. Baker challenged the conventional view of climate-sensitive infectious diseases (CSIDs), noting that they include vector transmitted diseases and directly transmitted diseases, exhibit seasonal outbreak patterns, and demonstrate variation by latitude.

Dr. Galvão emphasized that climate-driven health risks are changing across generations, with those born in 2020 facing significantly different risks than those born in 1950. He stressed that future generations’ health outcomes will depend on the immediacy and effectiveness of current policy decisions, calling for greater alignment between global frameworks—including the UN’s Sustainable Development Goals, the Paris Agreement, and the Sendai Framework—to address climate-related health challenges. Dr. de Oliveira showcased genomic surveillance as a tool for responding to climate-driven epidemics, emphasizing how real-time genetic sequencing can support epidemic response, biomedical discovery, and vaccine development.
