Conference Details
The Sabin Center for Climate Change Law and the Columbia Climate School will host a conference on the topic of Attribution Science and Climate Law at Columbia University on January 9-10, 2025. The purpose of this conference is to bring together scientific and legal experts to discuss how advances in climate change detection and attribution science can inform legal decisions related to climate change.
Attribution science provides critical insights on both the impacts attributable to anthropogenic climate change and the relative contributions of different sources for those impacts. This research plays an important role in climate litigation as well as policy-making and regulatory decision-making. For example, courts refer to attribution research when assessing legal obligations with regards to the mitigation of climate change and its harmful impacts. Attribution research is also used to support policy decisions and administrative actions, such as greenhouse gas regulations, adaptation measures, and protections for climate-imperiled species.
This conference will further advance collaboration between the scientific, legal and policy-making communities by bringing together a diverse group of researchers and practitioners to share insights on the status of attribution research and its relevance to climate law and policy. We anticipate that the participants will include physical scientists, public health researchers, economists, and social scientists, as well as legal scholars and practitioners. Three key goals of the conference are to: (i) advance substantive understanding of attribution science and its role in legal and policy decision-making, (ii) facilitate networking and discussion among diverse researchers and stakeholders, and (iii) identify concrete ways in which researchers can continue to collaborate across the scientific and legal fields.
The conference will consist of multiple presentations and panels focusing on some of the most pressing questions related to attribution research and its role in policy and legal decision-making, including:
- Scientific context: What is “detection and attribution” research, how has this field evolved over time, and how does it fit within the broader field of climate science? What are some of the major trends that have been attributed to human influence on the climate, and how has the evidence evolved before and since IPCC AR6?
- Legal context: How is science used in environmental lawmaking and litigation? Why does attribution science matter for legal decision-making, what sorts of legal claims are being filed and how does the science factor into these claims?
- Extreme event attribution: What are the different approaches to extreme event attribution, how might the suitability of these approaches differ depending on legal/policy application, and how can they complement one another?
- Impact attribution: What is the current status of research with regards to the attribution of different impacts, including but not limited to health impacts, food and water impacts, ecological impacts, socioeconomic impacts, and humanitarian impacts?
- Attribution of climate injuries and damages: To what extent can attribution research support decisions on injuries and damages attributable to specific quantities of emissions and specific responsible parties? What types of damages are quantifiable and how?
The conference will consist of a public event that is recorded and live-streamed.
